Definitions
- lymphoblastoid cell lines provide a self -renewable source of material, and are purported to avoid the effects of environmental exposure of cells from fresh blood. Fresh blood, however, with phenotypic state information gathered at time of harvesting, may be more informative than immortalized lymphocytes, and may avoid some of the caveats of Epstein- Barr virus (EBV) immortalization and cell culture passaging.
- EBV Epstein- Barr virus

- the level of the biomarker is determined by analyzing the expression level of
- RNA transcripts In an aspect, the expression level of the biomarker is determined by analyzing the level of protein or peptides or fragments thereof. Suitable detection techniques include microarray gene expression analysis, polymerase chain reaction (PCR), real-time PCR, quantitative PCR, immunohistochemistry, enzyme-linked immunosorbent assays (ELISA), and antibody arrays.
- PCR polymerase chain reaction
- ELISA enzyme-linked immunosorbent assays
- the determination of the level of the plurality of biomarkers is performed by an analysis of the presence or absence of the biomarkers.

- a treatment plan may be a personalized plan for the patient.
- a method for clinical screening of agents capable of affecting a mood disorder includes the steps of:
- a mood disorder microarray includes a plurality of nucleic acid molecules representing genes selected from the group of genes listed in Tables 3 and 7.
- a diagnostic microarray includes a panel of about 10 biomarkers that are predictive of a mood disorder, wherein the microarray includes nucleic acid fragments representing biomarkers designated as Mbp, Edg2, Fzd3, Atxnl, Ednrb for high mood and Fgfrl, Mag, Pmp22, Ugt8, Erbb3 for low mood.

- BioM Mood Prediction Score is based on the ratio of the sum of the scores for high mood biomarkers and sum of scores for low mood biomarkers, multiplied by 100.A cutoff score of 100 and above was used for high mood, inf- infinity- denominator is 0.
- FIG. 6 shows Connectivity Map interrogation of drugs that have similar gene expression signatures to that of high mood.
- a score of 1 indicates a maximal similarity with the gene expression effects of high mood, and a score of -1 indicates a maximal opposite effects to high mood.
- BP- bipolar Mood scores are based on subject self -report on mood VAS scale administered at time of blood draw.
- A is scored as 0, M as 0.5 and P as 1.
- BioM Mood Prediction Score is based on the ratio of the sum of the scores for high mood biomarkers and sum of scores for low mood biomarkers, multiplied by 100. A cutoff score of 100 and above was used for high mood.
- Patterns of changes in the blood that reflect whether a person has low mood (depression) or high mood (mania) are disclosed.
- these changes are analyzed at the level of gene expression, and involved genes that generally are expressed in the brain.
- Blood-based screening is clinically easier to perform than a cerebro-spinal fluid (CSF) analysis or a nasal epithelium bipopsy.
- CSF cerebro-spinal fluid
- an antidepressant medication may be started only initially, and if bipolar, will be flipped by the antidepressant into a mixed state or frank mood elevation- hypomania or mania.
- a panel of mood state markers such unclear patients are monitored by repeated lab tests after the antidepressant is started, and if the markers indicate a shift beyond normal mood, to high mood, then medications can be systematically changed, a mood stabilizer added, and a potentially dangerous and certainly dangerous episode for the patient averted. This approach is useful, especially in children and adolescents, who are hard to diagnose using traditional clinical criteria only, and in whom mood states rapidly change.
- Biomarkers disclosed herein may be personalized and tailored to the individual, based on their biomarker profiles.
- the biomarkers disclosed herein are (i) derived from fresh blood, not immortalized cell lines; (ii) capable of providing quantitative mood state information obtained at the time of the blood draw; (iii) were derived from comparisons of extremes of low mood and high mood in patients, as opposed to patients vs. normal controls (where the differences could be due to a lot of other environmental factors, medication (side) effects vs.
- Pharmacogenomic mouse model of relevance to bipolar disorder includes treatments with an agonist of the illness/bipolar disorder-mimicking drug (methamphetamine) and an antagonist of the illness/ bipolar disorder-treating drug (valproate).
- the pharmacogenomic approach is a tool for tagging genes that may have pathophysiological relevance. As an added advantage, some of these genes may be involved in potential medication effects present in human blood data (FIG. 2).
- a focused approach was used to analyze discrete quantitative phenotypic item (phene) — a Visual-Analog Scale (VAS) for mood.
- phene a Visual-Analog Scale
- This approach avoids the issue of corrections for multiple comparisons that would arise if one were to look in a discovery fashion at multiple phenes in a comprehensive phenotypic battery (PhenoChipping) changed in relationship with all genes on a GeneChip microarray. Larger sample cohorts would be needed for the latter approach.
- a panel of a subset of top candidate biomarker genes for mood state identified by the approach described herein was then used to generate a prediction score for mood state (low mood vs. high mood). This prediction score was compared to the actual self-reported mood scores from bipolar subjects in the primary cohort (FIG. 4). This panel of mood biomarkers and prediction score were also examined in a separate independent cohort of psychotic disorders patients for which gene expression data and mood state data (FIG.5) were obtained, as well as in a second independent bipolar cohort (FIG.6).
- Sample size for human subjects is comparable to the size of cohorts for human postmortem brain gene expression studies in the field. Live donor blood samples instead of postmortem donor brains were studied, with the advantage of better phenotypic characterization, more quantitative state information, and less technical variability. This approach also permits repeated intra-subject measures when the subject is in different mood states.
- biomarker genes for mood will show this complete induction related to state, but rather some will show modulation in gene expression levels, and are thus missed by a stringent filtering approach.
- biomarker genes for mood will show this complete induction related to state, but rather some will show modulation in gene expression levels, and are thus missed by a stringent filtering approach.
- a validation of the novel and non-obvious approach described herein is the fact that the biomarker panel showed sensitivity and specificity, of a comparable nature, in both independent replication cohorts (psychotic disorder cohort and secondary bipolar cohort).
- the approach of using a visual analog scale phene reflecting an internal subjective experience of well being or distress (as opposed to more complex and disease specific state/trait clinical instruments), and looking at extremes of state combined with robust differential expression based on A/P calls, and Convergent Functional Genomics prioritization is able to identify state biomarkers for mood, that are, at least in part, independent of specific diagnoses or medications. Nevertheless, a comparison with existing clinical rating scales (FIG.
- actimetry and functional neuroimaging as well as analysis of biomarker data using such instruments may be of interest, as a way of delineating state vs. trait issues, diagnostic boundaries or lack thereof, and informing the design of clinical trials that may incorporate clinical and biomarker measures of response to treatment.
- a subset of top candidate biomarker genes include five genes involved in myelination (
- genes which have a well-established role in brain functioning may show changes in blood in relationship to psychiatric symptoms state (FIG. 3, Table 3 and Table 7), and moreover that the direction of change may be concordant with that found in human postmortem brain studies. It is possible that trait promoter sequence mutations or epigenetic modifications influence expression in both tissues (brain and blood), and that state dependent transcription factor changes that modulate the expression of these genes may be contributory as well.
- myelin, growth factors are prominent players in mood disorders, and are reflected in the blood profile. Myelin abnormalities have emerged as a common if perhaps non-specific denominator across a variety of neuropsychiatric disorders. For exmaple, Mbp, is a top scoring candidate biomarker (FIG. 3), associated with high mood state.
- Mbp is a top scoring candidate biomarker (FIG. 3), associated with high mood state.
- the data provided herein regarding insulin growth factor signaling changes may provide an underpinning for the co-morbidity with diabetes and metabolic syndrome often encountered in mood disorder patients. These changes may be etiopathogenic, compensatory mechanisms, side-effects of medications, or results of illness - induced lifestyle changes (FIG. 2B).
- depression as opposed to high mood state (FIG. 3 and Table 3) indicates that depression may have more of an impact on blood gene expression changes, perhaps through a neuro-endocrine- immunological axis, as part of a whole-body reaction to a perceived hostile environment.
- biomarker genes identified herein have no previous evidence for involvement in mood disorders (Tables 3 and 7). They merit further exploration in genetic candidate gene association studies, as well as comparison with emerging results from whole -genome association studies of bipolar disorder and depression. If needed, the composition of biomarker panels for mood can be refined or changed for different sub-populations, depending upon the availability of additional evidence. Panels containing different number of biomarkers and different biomarkers can be developed using the guidelines described herein and from the biomarkers identified herein. A large number of the biomarkers that would be of use in different panels and permutations are already present in the complete list of candidate biomarker genes identified (Tables 3 and 7).
- the mood stabilizer drug valproate also a HDAC inhibitor, as well as sodium phenylbutirate and another HDAC inhibitor, trichostatin A, were shown to induce alpha-synuclein in neurons through inhibition of HDAC and that this alpha-synuclein induction was critically involved in neuroprotection against glutamate excitotoxicity.
- Human postmortem brain studies, as well as animal model and clinical studies have implicated glutamate abnormalities and histone deacetylase modulation as therapeutic targets in mood disorders.
- Novobiocin is an antibiotic drug that also has anti-tumor activity and apoptosis- inducing properties, through Hsp90 inhibition of Akt kinase an effect opposite to that of the valproate, trichostatin A and sodium phenylbutyrate (Table 6).
- This connectivity map analysis with a mood panel genes provides an interesting external biological cross-validation for the internal consistency of the biomarker approach, as well as illustrates the utility of the connectivity map for non-hypothesis driven identification of novel drug treatments and interventions.
- the data presented herein has not found reliable blood evidence for some of the top candidate genes derived from postmortem work, such as: Grial(glutamate receptor, ionotropic, AMPAl (alpha I)), Grikl (glutamate receptor, ionotropic, kainate 1), Gsk3b (glycogen synthase kinase 3 beta) and Arntl aryl hydrocarbon receptor nuclear translocator-like.
- BioM-10 A predictive score developed based on a panel of 10 top candidate biomarkers, designated herein as BioM-10 (5 for high mood, 5 for low mood) shows specificity and sensitivity for high mood and low mood states.
- a panel of candidate biomarker genes identified by this approach was then used to generate a prediction score for mood state (low mood/depression vs. high mood/mania). This prediction score was compared to the actual self -reported mood scores from human subjects. The prediction score developed by the analysis of convergent data provided a highly correlative basis for the diagnosis of mood state.
- a panel of biomarkers illustrated in Table 3 is suitable. These biomarkers include Mbp, Edg2, Fgfrl, Fzd3, Mag, Pmp22, Ugt8, Erbb3, Igfbp4, Igfbp ⁇ , Pde ⁇ d , Ptprm, Nefh, Atp2cl, Atxnl, Btgl, C6orfl82, Dicer 1, Dnajc ⁇ , Ednrb, Elovl5, Gnal, Klf5, Lin7a, Manea, Nupll, Pde ⁇ b, Slc25a23, Synpo, Tgm2, Tjp3, Tpd52, Trpcl, Bclafl, Gosr2, Rdx, Wdr34, Bic, C8orf42, Dock9, Hrasls, Ibrdc2, P2ryl2, Speed, Vil2.
- Pmp22, Ugt8, Erbb3, Igfbp4, and Igfbp ⁇ is suitable for diagnosing or predicting mood disorder.
- a panel of biomarkers include for example, Mbp, Edg2, Fzd3, Atxnl, and Ednrb that are increased in high mood (mania) condition.
- An embodiment of a first sub-group of markers that are used for analysis include for example: Mbp, Edg2, Fzd3, Atxnl, Ednrb (markers for high mood) and Fgfrl, Mag, Pmp22, Ugt8, Erbb3 (markers for low mood).
- An embodiment includes a second sub-group e.g., Pde9a, Plxndl, Camk2d, Dio2, Lepr (markers for high mood) and Igfbp4, Igfbp ⁇ , Pde ⁇ d, Ptprm, Nefh Atp2cl (markers for low mood).
- An embodiment includes a fifth sub-group e.g., Usp7, Zdhhc4, Znfl69, Cuedcl, Bivm (markers for high mood) and Pde ⁇ b, Slc25a23, Synpo, Tgm2, Tjp3 (markers for low mood).
- An embodiment includes a sixth sub-group e.g., Hla-dqal, C20orf94, C21orf56, F1J10986, Loc91431 (markers for high mood), Tpd52, Trpcl, Phldal, Znf502, Amn (markers for low mood) or a combination of one or more of the sub-goups 1-6 disclosed herein.
- Sub-groups 1-5 constitute a representative example and any number of sub-groups that has about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 200, 300, 400, 500, 600, or more markers selected from Table 7.
- An embodiment of a first sub-group of markers that are used for analysis include for example: Mbp, Edg2, Fzd3, Atxnl, Ednrb (markers for high mood), Fgfrl, Mag, Pmp22, Ugt8, Erbb3 (markers for low mood);
- second subgroup includes for example: Pde9a, Plxndl, Camk2d, Dio2, Lepr (markers for high mood), Igfbp4, Igfbp ⁇ , Pde ⁇ d, Ptprm, Nefh, (markers for low mood);
- third subgroup includes for example: Myom2, Nfix, Nt5m, Or7el04p, Rrpl (markers for high mood), Btgl, Elov5, Lrrc ⁇ b, Dicerl, Atp2cl, (markers for low mood);
- fourth subgroup includes for example: Sept2, Sfrs4, Sla2, Tex261, Ube2i (markers for high mood), Gnal
- Sub-groups 1-5 constitute a representative example and any number of sub-groups that has about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 200, 300, 400, 500, 600, or more markers selected from Tables 3 and 7.
- a panel of 36 biomarkers is a suitable subset that is useful in diagnosing a mood disorder. Larger subsets that includes for example, 150, 200, 250, 300, 350, 400, 450, 500, 600 or about 700 markers are also suitable. Smaller subsets that include high-value markers including about 2, 5, 10, 15, 20, 25, 50, 75, and 100 are also suitable.
- a variable quantitative scoring scheme can be designed using any standard algorithm, such as a variable selection or a subset feature selection algorithms can be used. Both statistical and machine learning algorithms are suitable in devising a frame work to identify, rank, and analyze association between marker data and phenotypic data (e.g., mood disorders).
- a prediction score for each subject is derived based on the presence or absence of e.g., 10 biomarkers of the panel in their blood.
- Each of the 10 biomarkers gets a score of 1 if it is detected as “present” (P) in the blood form that subject, 0.5 if it is detected as “marginally present” (M), and 0 if it is called “absent” (A).
- P present
- M marginally present
- A absent
- the predictive score was compared with actual self-reported mood scores in a primary cohort of subjects with a diagnosis of bipolar mood disorder.
- a prediction score of 100 and above had a 84.6 % sensitivity and a 68.8 % specificity for predicting high mood.
- a prediction score below 100 had a 76.9 % sensitivity and 81.3 % specificity for predicting low mood.
- the term "present” indicates that a particular biomarker is expressed to a detectable level, as determined by the technique used. For example, in an experiment involving a microarray or gene chip obtained from a commercial vendor Affymetrix (Santa Clara, CA), the embedded software rendered a "present” call for that biomarker.
- present refers to a detectable presence of the transcript or its translated protein/peptide and not necessarily reflects a relative comparion to for example, a sample from a normal subject. In other words, the mere presence or absence of a biomarker is assigned a value, e.g., 1 and a prediction score is calculated as described herein.
- marginally present refers to border line expression level that may be less intense than the "present” but statistically different from being marked as "absent” (above background noise), as determined by the methodology used.
- absent is used. For example, if a subject has a plurality of markers for high or low mood are differentially expressed, a prediction based on the differential expression of markers is determined. Differential expression of about 1.2 fold or 1.3 or 1.5 or 2 or 3 or 4 or 5-fold or higher for either increased or decreased levels can be used. Any standard statistical tool such as ANOVA is suitable for analysis of differential expression and association with high or low mood diagnosis or prediction.
- a prediction based on the analysis of either high or low mood markers alone may also be practiced. If a plurality of high mood markers (e.g., about 6 out of 10 tested) are differentially expressed to a higher level compared to the low mood markers (e.g., 4 out of 10 tested), then a prediction or diagnosis of high mood status can be made by analyzing the expression levels of the high mood markers alone without factoring the expression levels of the low mood markers as a ratio.
- a detection algorithm uses probe pair intensities to generate a detection p-value and assign a Present, Marginal, or Absent call.
- Each probe pair in a probe set is considered as having a potential vote in determining whether the measured transcript is detected (Present) or not detected (Absent). The vote is described by a value called the Discrimination score [R].
- the score is calculated for each probe pair and is compared to a predefined threshold Tau. Probe pairs with scores higher than Tau vote for the presence of the transcript. Probe pairs with scores lower than Tau vote for the absence of the transcript.
- the voting result is summarized as a p-value. The greater the number of discrimination scores calculated for a given probe set that are above Tau, the smaller the p-value and the more likely the given transcript is truly Present in the sample. The p-value associated with this test reflects the confidence of the Detection call.
- a two-step procedure determines the Detection p-value for a given probe set.
- the Discrimination score [R] is calculated for each probe pair and the discrimination scores are tested against the user-definable threshold Tau.
- the detection Algorithm assesses probe pair saturation, calculates a Detection p-value, and assigns a Present, Marginal, or Absent call.
- the default thresholds of the Affymetrix MAS 5 software were used.
- characteristics that determine the prediction include one or more of the biomarkers for the mood disorder disclosed herein.
- clinical outcome refers to biological or biochemical or physical or physiological responses to treatments or therapeutic agents that are generally prescribed for that condition compared to a condition would occur in the absence of any treatment.
- a “clinically positive outcome” does not necessarily indicate a cure, but could indicate a lessening of symptoms experienced by a subject.
- biomarker and “biomarker” are synonymous and as used herein, refer to the presence or absence or the levels of nucleic acid sequences or proteins or polypeptides or fragments thereof to be used for associating or correlating a phenotypic state.
- a biomarker includes any indicia of the level of expression of an indicated marker gene. The indicia can be direct or indirect and measure over- or under-expression of the gene given the physiologic parameters and in comparison to an internal control, normal tissue or another phenotype.
- Nucleic acids or proteins or polypeptides or portions thereof used as markers are contemplated to include any fragments thereof, in particular, fragments that can specifically hybridize with their intended targets under stringent conditions and immunologically detectable fragments.
- markers may be related. Marker may also refer to a gene or DNA sequence having a known location on a chromosome and associated with a particular gene or trait. Genetic markers associated with certain diseases or for pre-disposing disease states can be detected in the blood and used to determine whether an individual is at risk for developing a disease. Levels of gene expression and protein levels are quantifiable and the variation in quantification or the mere presence or absence of the expression may also serve as markers. Using proteins/peptides as biomarkers can include any method known in the art including, without limitation, measuring amount, activity, modifications such as glycosylation, phosphorylation, ADP- ribosylation, ubiquitination, etc., imunohistochemistry (IHC).
- IHC imunohistochemistry
- array refers to an array of distinct polynulceotides, oligonucleotides, polypeptides, or oligopeptides synthesized on a substrate, such as paper, nylon, or other type of membrane, filter, chip, glass slide, or any other suitable solid support. Arrays also include a plurality of antibodies immobilized on a support for detecting specific protein products. There are several microarrays that are commercially available. A microarray may include one or more biomarkers disclosed herein. A panel of about 20 biomarkers as nucleic acid fragments can be included in an array.
- the nucleic acid fragments may include oligonucleotides or amplified partial or complete nucleotide sequences of the biomarkers.
- a microarray consists essentially of markers from Table 3. [00097]
- the microarray is prepared and used according to the methods described in U.S. Pat. No. 5,837,832, Chee et al.; PCT application WO95/11995, Chee et al.; Lockhart et al., 1996. Nat Biotech., 14:1675-80; and Schena et al., 1996. Proc. Natl.
- condition refers to any disease, disorder or any biological or physiological effect that produces unwanted biological effects in a subject.
- the term "subject" refers to an animal, or to one or more cells derived from an animal.
- the animal may be a mammal including humans.
- Cells may be in any form, including but not limited to cells retained in tissue, cell clusters, immortalized cells, transfected or transformed cells, and cells derived from an animal that have been physically or phenotypically altered.
- Suitable body fluids include a blood sample (e.g., whole blood, serum or plasma), urine, saliva, cerebrospinal fluid, tears, semen, and vaginal secretions. Also, lavages, tissue homogenates and cell lysates can be utilized.
- Mass-spectrometry, chromatography, real-time PCR, quantitative PCR, probe hybridization, or any other analytical method to determine expression levels or protein levels of the markers are suitable. Such analysis can be quantitative and may also be performed in a high-through put fashion.
- Cellular imaging systems are commercially available that combine conventional light microscopes with digital image processing systems to perform quantitative analysis on cells and tissues, including immunostained samples. (See e.g. the CAS-200 System (Becton, Dickinson & Co.))- Some other examples of methods that can be used to determine the levels of markers include immunohistochemistry, automated systems, quantitative IHC, semiquantitative IHC and manual methods.
- Other analytical systems include western blotting, immunoprecipitation, fluorescence in situ hybridization (FISH), and enzyme immunoassays.
- diagnosis refers to evaluating the type of disease or condition from a set of marker values and/or patient symptoms where the subject is suspected of having a disorder. This is in contrast to disease predisposition, which relates to predicting the occurrence of disease before it occurs, and the term “prognosis”, which is predicting disease progression in the future based on the marker levels/patterns.
- correlation refers to a process by which one or more biomarkers are associated to a particular disease state, e.g., mood disorder.
- identifying such correlation or association involves conducting analyses that establish a statistically significant association- and/or a statistically significant correlation between the presence (or a particular level) of a marker or a combination of markers and the phenotypic trait in the subject.
- An analysis that identifies a statistical association (e.g., a significant association) between the marker or combination of markers and the phenotype establishes a correlation between the presence of the marker or combination of markers in a subject and the particular phenotype being analyzed.
- This relationship or association can be determined by comparing biomarker levels in a subject to levels obtained from a control population, e.g., positive control— diseased (with symptoms) population and negative control— disease-free (symptom-free) population.
- the biomarkers disclosed herein provide a statistically significant correlation to diagnosis at varying levels of probability.
- Subsets of markers for example a panel of about 20 markers, each at a certain level range which are a simple threshold, are said to be correlative or associative with one of the disease states. Such a panel of correlated markers can be then be used for disease detection, diagnosis, prognosis and/or treatment outcome.
- Preferred methods of correlating markers is by performing marker selection by any appropriate scoring method or by using a standard feature selection algorithm and classification by known mapping functions.
- a suitable probability level is a 5% chance, a 10% chance, a 20% chance, a 25% chance, a 30% chance, a 40% chance, a 50% chance, a 60% chance, a 70% chance, a 75% chance, a 80% chance, a 90% chance, a 95% chance, and a 100% chance.
- Each of these values of probability is plus or minus 2% or less.
- a suitable threshold level for markers of the present invention is about 25 pg/mL, about 50 pg/mL, about 75 pg/mL, about 100 pg/mL, about 150 pg/mL, about 200 pg/mL, about 400 pg/mL, about 500 pg/mL, about 750 pg/mL, about 1000 pg/mL, and about 2500 pg/mL.
- Prognosis methods disclosed herein that improve the outcome of a disease by reducing the increased disposition for an adverse outcome associated with the diagnosis. Such methods may also be used to screen pharmacological compounds for agents capable of improving the patient's prognosis, e.g., test agents for mood disorders.
- the analysis of a plurality of markers for example, a panel of about 20 or 10 markers may be carried out separately or simultaneously with one test sample. Several markers may be combined into one test for efficient processing of a multiple of samples. In addition, one skilled in the art would recognize the value of testing multiple samples (for example, at successive time points) from the same individual. Such testing of serial samples may allow the identification of changes in marker levels over time, within a period of interest, or in response to a certain treatment.
- kits for the analysis of markers includes for example, devises and reagents for the analysis of at least one test sample and instructions for performing the assay.
- the kits may contain one or more means for using information obtained from marker assays performed for a marker panel to diagnose mood disorders.
- Probes for markers, marker antibodies or antigens may be incorporated into diagnostic assay kits depending upon which markers are being measured.
- a plurality of probes may be placed in to separate containers, or alternatively, a chip may contain immobilized probes.
- another container may include a composition that includes an antigen or antibody preparation. Both antibody and antigen preparations may preferably be provided in a suitable titrated form, with antigen concentrations and/or antibody titers given for easy reference in quantitative applications.
- kits may also include a detection reagent or label for the detection of specific reaction between the probes provided in the array or the antibody in the preparation for immunodetection.
- Suitable detection reagents are well known in the art as exemplified by fluorescent, radioactive, enzymatic or otherwise chromogenic ligands, which are typically employed in association with the nucleic acid, antigen and/or antibody, or in association with a secondary antibody having specificity for first antibody.
- the reaction is detected or quantified by means of detecting or quantifying the label.
- Immunodetection reagents and processes suitable for application in connection with the novel methods of the present invention are generally well known in the art.
- the reagents may also include ancillary agents such as buffering agents and protein stabilizing agents, e.g., polysaccharides and the like.
- the diagnostic kit may further include where necessary agents for reducing background interference in a test, agents for increasing signal, software and algorithms for combining and interpolating marker values to produce a prediction of clinical outcome of interest, apparatus for conducting a test, calibration curves and charts, standardization curves and charts, and the like.
- the methods of correlating biomarkers with treatment regimens can be carried out using a computer database.
- Computer-assisted methods of identifying a proposed treatment for mood disorders are suitable. The method involves the steps of (a) storing a database of biological data for a plurality of patients, the biological data that is being stored including for each of said plurality of patients (i) a treatment type, (ii) at least one marker associated with a mood disorder and (iii) at least one disease progression measure for the mood disorder from which treatment efficacy can be determined; and then (b) querying the database to determine the dependence on the marker of the effectiveness of a treatment type in treating the mood disorder, to thereby identify a proposed treatment as an effective treatment for a subject carrying the marker correlated with the mood disorder.
- treatment information for a patient is entered into the database (through any suitable means such as a window or text interface), marker information for that patient is entered into the database, and disease progression information is entered into the database. These steps are then repeated until the desired number of patients has been entered into the database.
- the database can then be queried to determine whether a particular treatment is effective for patients carrying a particular marker, not effective for patients carrying a particular marker, and the like. Such querying can be carried out prospectively or retrospectively on the database by any suitable means, but is generally done by statistical analysis in accordance with known techniques, as described herein.
- Pharmacogenomic mouse model of relevance to bipolar disorder consists of treatments with an agonist of the illness/bipolar disorder-mimicking drug (methamphetamine) and an antagonist of the illness/ bipolar disorder-treating drug (valproate).
- methamphetamine an agonist of the illness/bipolar disorder-mimicking drug
- valproate an antagonist of the illness/ bipolar disorder-treating drug
- the human subjects used in this example included those who were directly recruited, and data collected in other procedures/settings. Blood samples were collected.
- Subjects included men and women over 18 years of age. A demographic breakdown is shown in Table 1. Initial studies were focused primarily on a male population, due to the demographics of the catchment area (primarily male in a VA Medical Center), and to minimize any potential gender-related state effects on gene expression, which would have decreased the discriminative power of the analysis for the sample size used. Subjects were recruited from the general population, the patient population at the IU school of Medicine, the Indianapolis VA Medical Center, as well as various facilities that serve people with mental illnesses in Indiana. The subjects were recruited largely through referrals from care providers, the use of brochures left in plain sight in public places and mental health clinics, and through word of mouth. Subjects were excluded if they had significant medical or neurological illness or had evidence of active substance abuse or dependence.
- RNA extraction 2.5-5 ml of whole blood was collected into each PaxGene tube by routine venipuncture.
- PaxGene tubes contain proprietary reagents for the stabilization of RNA.
- the cells from whole blood will be concentrated by centrifugation, the pellet washed, resuspended and incubated in buffers containing Proteinase K for protein digestion. A second centrifugation step will be done to remove residual cell debris.
- the lysate is applied to a silica-gel membrane/column.
- the RNA bound to the membrane as the column is centrifuged and contaminants are removed in three wash steps.
- the RNA is then eluted using DEPC-treated water.
- Globin reduction To remove globin mRNA, total RNA from whole blood is mixed with a biotinylated Capture Oligo Mix that is specific for human globin mRNA. The mixture is then incubated for 15 min to allow the biotinylated oligonucleotides to hybridize with the globin mRNA. Streptavidin Magnetic Beads are then added, and the mixture is incubated for 30 min. During this incubation, streptavidin binds the biotinylated oligonucleotides, thereby capturing the globin mRNA on the magnetic beads.
- RNA binding Bead suspension is added to the samples, and using magnetic capture to wash and elute the GLOBINclear RNA.
- Second Strand cDNA Synthesis converts the single-stranded cDNA into a double- stranded DNA (dsDNA) template for transcription.
- the reaction employs DNA Polymerase and RNase H to simultaneously degrade the RNA and synthesize second strand cDNA.
- cDNA Purification removes RNA, primers, enzymes, and salts that would inhibit in vitro transcription.
- aRNA Purification removes unincorporated NTPs, salts, enzymes, and inorganic phosphate to improve the stability of the biotin-modified aRNA.
- Microarrays Biotin labeled aRNA are hybridized to Affymetrix HG-U133 Plus 2.0
- GeneChips according to manufacturer's protocols (Affymetrix Inc., Santa Clara, CA). All GAPDH 375' ratios should be less than 2.0 and backgrounds under 50. Arrays are stained using standard Affymetrix protocols for antibody signal amplification and scanned on an Affymetrix Gene Array 2500 scanner with a target intensity set at 250. Present/ Absent calls are determined using GCOS software with thresholds set at default values.
- mice were treated by intraperitoneal injection with either single-dose saline, methamphetamine (10 mg/kg), valproate (200 mg/kg), or a combination of methamphetamine and valproate (10 mg/kg and 200 mg/kg respectively).
- Three independent de novo biological experiments were performed at different times. Each experiment included three mice per treatment condition, for a total of 9 mice per condition across the three experiments.

- the quality of the total RNA was confirmed using an Agilent 2100 Bioanalyzer (Agilent Technologies, Palo Alto, CA). The quantity and quality of total RNA was also independently assessed by 260 nm UV absorption and by 260/280 ratios, respectively (Nanodrop spectrophotometer). Starting material of total RNA labeling reactions was kept consistent within each independent microarray experiment.
- Mouse Genome 430 2.0 arrays (Affymetrix, Santa Clara, CA) were used.
- the GeneChipTM Mouse Genome 430 2.0 Array contain over 45,000 probe sets that analyze the expression level of over 39,000 transcripts and variants from over 34,000 well- characterized mouse genes.
- Affymetrix Human Genome U133 Plus 2.0 GeneChip with over 40,000 genes and ESTs were used. Standard manufacturer's protocols were used to reverse transcribe the messenger RNA and generate biotinlylated cRNA.
- the amount of cRNA used to prepare the hybridization cocktail was kept constant intra-experiment. Samples were hybridized at 45°C for 17 hours under constant rotation. Arrays were washed and stained using the Affymetrix Fluidics Station 400 and scanned using the Affymetrix Model 3000 Scanner controlled by GCOS software. All sample labeling, hybridization, staining and scanning procedures were carried out as per manufacturer's recommendations.
- Microarray data analysis Data analysis was performed using Affymetrix Microarray Suite
- transcripts were called Present in at least one of the two samples (saline or drug) intra-experiment, and that were reproducibly changed in the same direction in at least two out of three independent experiments, were analyzed further.
- a high threshold was used, with at least 75% of subjects in a cohort showing a change in expression from Absent to Present between low and high mood ( reflecting an at least 3 fold mood state related enrichment of the genes thus filtered)
- a low threshold was also used, with at least 60% of subjects in a cohort showing a change in expression from Absent to Present between low and high mood ( reflecting an at least 1.5 fold mood state related enrichment of the genes thus filtered).
- the high threshold identified candidate biomarker genes that are more common for all subjects, with a lower risk of false positives, whereas the lower threshold identified genes that are present in more restricted subgroups of subjects, with a lower risk of false negatives.
- the high threshold candidate biomarker genes have, as an advantage, a higher degree of reliability, as they are present in at least 75% of all subjects with a certain mood state (high or low) tested. They may reflect common aspects related to mood disorders across a diverse subject population, but may also be a reflection of the effects of common medications used in the population tested, such as mood stabilizers.
- the low threshold genes may have lower reliability compared to the high threshold, being present in at least 60% of the subject population tested, but, nevertheless, captures more of the diversity of genes and biological mechanisms present in a genetically diverse human subject population.
- Affymetrix Human Genome U133 Plus 2.0 GeneChip by using the high threshold, in an embodiment, about 21 novel candidate biomarker genes (13 genes with known functions and 7 ESTs) (Table 3), of which 8 had at least one line of prior independent evidence for potential involvement in mood disorders (i.e. CFG score of 3 or above).
- a larger list totaling 661 genes (539 genes and 122 ESTs) (Table 7), of which an additional 24 had at least two lines of prior independent evidence for potential involvement in mood disorders (i.e. CFG score of 3 or above).
- four of the low threshold candidate biomarker genes (Bclafl and Rdx8, Gosr2 and Wdr3413) are changed in expression in the same direction, in lymphoblastoid cell lines (LCLs) from bipolar subjects.
- a panel e.g, the BioM-10 Mood panel
- a cohort of 29 bipolar disorder subjects containing the 26 subjects (13 low mood, 13 high mood) from which the candidate biomarker data was derived, as well as 3 additional subjects with mood in the intermediate range (self -reported mood scores between 40 and 60) was used.
- a prediction score for each subject based on the presence or absence of the 10 biomarkers of the panel in the blood GeneChip data.
- Each of the 10 biomarkers gets a score of 1 if it is detected as Present (P) in the blood form that subject, 0.5 if it is detected as Marginally Present (M), and 0 if it is called Absent (A).
- the primary and secondary bipolar mood disorder cohorts are apriori more related and germane to mood state biomarkers identification, but may have blood gene expression changes due at least in part to the common pharmacological agents used to treat bipolar mood disorders.
- the psychotic disorders cohort may have blood gene expression changes related to mood state irrespective of the diagnosis and the different medication classes subjects with different diagnoses are on (Table 1 and FIG. 2B).
- the psychosis cohort was also notably different in terms of the ethnic distribution (see Table Ib).
- biomarkers identified herein provide quantitative tools for predicting disease states/conditions in subjects suspected of having a mood disorder or in any individual for psychiatric evaluation.
- BLAST analysis identified the closest (most similar) known gene existing in the database (the highest known gene at the top of the BLAST list of homologues) which then could be used to search the GeneCards database (Weizmann Institute, Rehovot, Israel). Probe-sets that did not have a known gene were labeled "EST" and their accession numbers were kept as identifiers.
- Postmortem convergence was deemed to occur for a gene (or a biomarker) if there were human postmortem data showing changes in expression of that gene in brains from patients with mood disorders (bipolar disorder, depression), or secondarily of other major neuropsychiatric disorders that impact mood (schizophrenia, anxiety, alcoholism).
- the gene may have positive reports from candidate gene association studies, or map within lOcM of a microsatellite marker for which at least one study demosntrated evidence for genetic linkage to mood disorders (bipolar disorder or depression) or secondarily to another neuropsychiatric disorder.
- the University of Southampton's sequence-based integrated map of the human genome The Genetic Epidemiological Group, Human Genetics Division, was used to obtain cM locations for both genes and markers. The sex-averaged cM value was calculated and used to determine convergence to a particular marker.
- the Marshfield database Center for Medical Genetics, Marshfield, WI, USA was used with the NCBI Map Viewer web-site to evaluate linkage convergence.
- Biomarkers were given the maximum score of 2 points if changed in the human blood samples with high threshold analysis, and only 1 point if changed with low threshold.
- Biomarkers received 1 point for each external cross-validating line of evidence human postmortem brain data, human genetic data, animal model brain data, and animal model blood data.
- Biomarkers received additional bonus points if changed in human brain and blood, as follows:
- Biomarkers also received additional bonus points if changed in brain and blood of the animal model, as follows:
- the scoring pattern described herein is biased more towards awarding additional points for live subject human blood data (if it made the high threshold cut) than literature-derived human postmortem brain data, human genetic data, or the animal model data.
- the human blood-brain concordance is weighted more favorably than the animal model blood-brain concordance.
- the scoring analysis presented herein is just one example of assigning quantifiable values to prioritizing biomarkers for mood disorder analysis. Other ways of weighing the scores of line of evidence may give slightly different results in terms of prioritization, if not in terms of the list of genes per se.
- weightage given to a particular evidence may be varied. Additional scoring matrices may also be included to account for additional variables.
- One such example would be the temporal aspect — how long a particular biomarker is turned on.
- RNA is isolated from the blood using standard protocols, for example with PAXgene blood RNA extraction kit (PreAnalytiX, a QIAGEN/BD company), followed by GLOBINclearTM-Human or GLOBINclearTM-Mouse/Rat (Ambion/ Applied Biosystems Inc., Austin, TX) to remove the globin mRNA.
- PAXgene blood RNA extraction kit PreAnalytiX, a QIAGEN/BD company
- GLOBINclearTM-Human or GLOBINclearTM-Mouse/Rat Ambion/ Applied Biosystems Inc., Austin, TX
- the labeled RNA is then quantified for the presence of one or more of the biomarkers disclosed herein.
- gene expression analysis is performed using a panel of about 10 biomarkers (e.g., BioM 10 panel) by any standard technique, for example microarray analysis or quantitative PCR or an equivalent thereof.
- the gene expression levels are analyzed and the absent/present state or fold changes (either increased, decreased, or no change) are determined and a score is established
- Biomarkers disclosed herein are used in the form of panels of biomarkers, as exemplified by a BioM-10 Mood panel, for clinical laboratory tests for mood disorders. Such tests can be: 1) at an mRNA level, quantitation of gene expression through polymerase chain reaction, 2) at a protein level, quantitation of protein levels through immunological approaches such as enzyme-linked immunosorbent assays (ELISA).
- ELISA enzyme-linked immunosorbent assays
- CSF urine
- urine may play a desirable part of personalizing treatment to increase effectiveness and avoid adverse reactions- personalized medicine in psychiatry.
- Biomarker-based tests for mood disorders help: 1) Diagnosis, early intervention and prevention efforts; 2) Prognosis and monitoring response to various treatments; 3) New neuropsychiatric drug development efforts by pharmaceutical companies, at both a pre-clinical and clinical (Phase I, II and III) stages of the process; 4) Identifying vulnerability to mood problems for people in high stress occupations (for example, military, police, homeland security).
- Example 4A Diagnosis, early intervention and prevention efforts.
- a patient with no previous history of mood disorders presents to a primary care doctor or internist complaining of non-specific symptoms: low energy, fatigue, general malaise, aches and pains.
- Such symptoms are reported in conditions such as stress after a job loss, bereavement, mononucleosis, fibromyalgia, and postpartum in the general population, as well as Gulf War syndrome in veterans.
- a panel of mood biomarkers can substantiate that the patient is showing objective changes in the blood consistent with a low mood/depressive state.
- anti-depressant medications such as Prozac (fluoxetine), Zolof (sertraline), Celexa (citalopram), Cymbalta (duloxetine), Effexor (venlafaxine) or Wellbutrin (buproprion).
- Example 4B Clinical diagnosis of a young patient.
- a young patient child, adolescent, young adult
- mood biomarkers panels of mood biomarkers
- Example 4C Monitoring mood biomarkers over an extended period. Many patients with bipolar disorder may present initially with a depressive episode to their primary care doctor or psychiatrist. Monitoring mood biomarkers over time may also help to differentiate depression vs. bipolar disorder (manic-depression). This distinction is helpful because the first-line treatments for the two disorders are different: anti-depressants for depression, mood stabilizers for bipolar. If patients are miss-diagnosed as depressives instead of bipolars, and started on anti-depressant medications only, this can lead to activation and flip into manic states.
- Example 4D Prognosis and monitoring response to various treatments.
- depression initiating medication treatment with current anti-depressants medications is a trial-and -error endeavor. It takes up to 6-8 weeks to see if a medication truly works.
- a baseline biomarker panel test and then a repeat test early one in treatment (after 1 week, for example), there would be an early objective indication if an anti-depressant is starting to work or not, and if a switch to another medication is indicated. This would save time and avoid needles suffering for patients, with the attendant socio-economic losses.
- Example 4F Determining adequacy of treatment plan. Objective monitoring with blood biomarker panels of the effect of less reliable or evidence-based interventions: psychotherapy, lifestyle changes, diet and exercise programs for improving mood health. This will show whether the particular intervention works, is sufficient, or medications may need to be added to the regimen.
- Example 4G Identifying vulnerability to developing mood problems for people in high stress occupations.
- Military personnel (recruits in boot-camp, active duty soldiers), other people in high-stress jobs (police, homeland security, astronauts), can be monitored on a regular basis to detect early objective changes in mood biomarker profile that would indicate the need for preventive intervention and/or the temporary removal from a high-stress environment.
- Biomarker testing may provide an objective signature of the genetic and biological make-up of the responders, which can inform recruitment for subsequent validatory clinical trials with higher likelihood of success, as well as inform which patients should be getting the medication, once it is

Description
BLOOD BIOMARKERS FOR MOOD DISORDERS
CROSS REFERENCE TO RELATED APPLICATIONS
[0001 ] This application claims priority to U.S. provisional application Ser. No. 60/909,859, filed
April 2, 2007, the disclosure of which is hereby incorporated by reference in its entirety.
[0002] Part of the work during the development of this invention was made with government support from the National Institutes of Health under grant NIMH ROl MH071912-01. The U.S. Government has certain rights in the invention.
BACKGROUND
[0003] Research into the biological basis of mood disorders (e.g., bipolar disorders, depression) has been primarily focused in human and animal studies mostly independently. The two avenues of research have complementary strengths and weaknesses. In human genetic studies, for example, in samples of patients with mood disorders and their family members, positional cloning methods such as linkage analysis, linkage-disequilibrium mapping, and candidate-gene association analysis are narrowing the search for the chromosomal regions harboring risk genes for the illness and, in some cases, identifying plausible candidate genes and polymorphisms that will require further validation. Human postmortem brain gene expression studies have also been employed as a way of trying to identify candidate genes for mood and other neuropsychiatric disorders. In general, human studies suffer from issues of sensitivity- the signal is often difficult to detect due to the noise generated by the genetic heterogeneity of individuals and the effects of diverse environmental exposures on gene expression and phenotypic penetrance.
[0004] In animal studies, carried out in isogenic strains with controlled environmental exposure, the identification of putative neurobiological substrates of mood disorders is typically accomplished by modeling human mood disorders through pharmacological or genetic manipulations. Animal model studies suffer from issues of specificity- questions regarding direct relevance to the human disorder modeled. Each independent line of investigation (i.e., human and animal studies) is contributing to the incremental gains in knowledge of mood disorders etiology witnessed in the last decade.
[0005] However, a lack of integration between these two lines of investigation, hinders scientific understanding and slows the pace of discovery. Psychiatric phenotypes, as currently defined, are primarily the result of clinical consensus criteria rather than empirical determination. The present disclosure provides methods and compositions that empirically determine disease states for diagnosis and treatment.
[0006] Objective biomarkers of illness and treatment response would make a significant difference in the ability to diagnose and treat patients with psychiatric disorders, eliminating subjectivity and reliance of patient's self -report of symptoms. Blood gene expression profiling has emerged as a particularly interesting area of research in the search for peripheral biomarkers. Most of the studies to date have focused on human 1 lymphoblastoid cell lines (LCLs) gene expression profiling,
comparison between illness groups and normal controls. They suffer from one of both of the following limitations: 1) the sample size used is often small. Given the genetic heterogeneity in human samples and the effects of illness state and environmental history, including medications and drugs, on gene expression, it may not be reliable to extract bona fide findings. 2) Use of lymphoblastoid cell lines — passaged lymphoblastoid cell lines provide a self -renewable source of material, and are purported to avoid the effects of environmental exposure of cells from fresh blood. Fresh blood, however, with phenotypic state information gathered at time of harvesting, may be more informative than immortalized lymphocytes, and may avoid some of the caveats of Epstein- Barr virus (EBV) immortalization and cell culture passaging.
[0007] The current state of the understanding of the genetic and neurobiological basis for mood disorders (such as bipolar disorder and depression) in general, and of peripheral molecular biomarkers of the illness in particular, is still inadequate. Almost all of the fundamental genetic, environmental, and biological elements needed to delineate the etiology and pathophysiology of mood disorders are yet to be completely identified, understood and validated. One of the rate- limiting steps has been the lack of concerted integration across disciplines and methodologies. The use of a multidisciplinary, integrative research framework as in the present disclosure provided herein, should lead to a reduction in the historically high rate of inferential errors committed in studies of complex diseases like bipolar disorder and depression.
[0008] Identification and validation of peripheral biomarkers for bipolar mood disorders has proven arduous, despite recent large-scale efforts. Human genomic studies are susceptible to the issue of being underpowered, due to genetic heterogeneity, the effect of variable environmental exposure on gene expression, and difficulty of accrual of large samples. Animal model gene expression studies, in a genetically homogeneous and experimentally tractable setting, can avoid artifacts and provide sensitivity of detection. Subsequent comparisons of the animal datasets with human genetic and genomic datasets can ensure cross-validatory power and specificity.
[0009] Convergent functional genomics (CFG), is an approach that translationally cross-matches animal model gene expression data with human genetic linkage data and human tissue data (blood, postmortem brain), as a Bayesian strategy of cross validating findings and identifying candidate genes, pathways and mechanisms for neuropsychiatric disorders. Predictive biomarkers for mood disorders are desired for clinical diagnosis and treatment purposes. The present disclosure provides several biomarkers that are predictive of mood disorders in clinical settings.
SUMMARY [00010] Methods and compositions to clinically diagnose mood disorders using a panel of biomarkers are disclosed. A panel of biomarkers may include 1 to about 100 or more biomarkers.

DETAILED DESCRIPTION
[00043] Patterns of changes in the blood that reflect whether a person has low mood (depression) or high mood (mania) are disclosed. In an embodiment, these changes are analyzed at the level of gene expression, and involved genes that generally are expressed in the brain.
[00044] Unlike cancer, in psychiatric disorders, one cannot perform a biopsy the target organ (brain).
Therefore, implementing a readily accessible peripheral readout in blood or any other non-brain tissue is highly useful. Blood-based screening is clinically easier to perform than a cerebro-spinal fluid (CSF) analysis or a nasal epithelium bipopsy.
[00045] Relying on the patients' self-report of symptoms and the clinician's impression of how ill the patient is alone do not necessarily provide an accurate diagnosis. Because patients' mind itself is affected in a mood disorder, their reporting of symptoms of how they feel may not be accurate or may not predict the nature of disease outcome. For example, patients aren't sure how ill they really are, and neither is the clinician- sometimes dismissing their symptoms, sometimes overestimating them. Therefore, an objective test for disease state, disease severity, and to measure response to treatment is highly desirable.
[00046] For example, for depression in general, a patient gets started on an antidepressant, and it may take weeks or months before it is known if the medication is working or if something else needs to be tried. A blood test for mood state for the biomarkers disclosed herein is able to objectively reflect whether a treatment works.
[00047] For example, for someone diagnosed as depressed but is in reality bipolar (manic- depressive), an antidepressant medication may be started only initially, and if bipolar, will be flipped by the antidepressant into a mixed state or frank mood elevation- hypomania or mania. With a panel of mood state markers, such unclear patients are monitored by repeated lab tests after the antidepressant is started, and if the markers indicate a shift beyond normal mood, to high mood, then medications can be systematically changed, a mood stabilizer added, and a potentially dangerous and certainly miserable episode for the patient averted. This approach is useful, especially in children and adolescents, who are hard to diagnose using traditional clinical criteria only, and in whom mood states rapidly change.
[00048] Sub-groups of biomarkers can be identified for different subpopulations, potential gender differences, age related differences, response to different medications. Biomarkers disclosed herein may be personalized and tailored to the individual, based on their biomarker profiles.
[00049] In an aspect, the biomarkers disclosed herein are (i) derived from fresh blood, not immortalized cell lines; (ii) capable of providing quantitative mood state information obtained at the time of the blood draw; (iii) were derived from comparisons of extremes of low mood and high mood in patients, as opposed to patients vs. normal controls (where the differences could be due to a
lot of other environmental factors, medication (side) effects vs. no medications; (iv) scored based on an all or nothing (Absent/Present) call for gene expression changes, not incremental changes in expression — statistically more robust and avoids false positives; (v) based on integration of multiple independent lines of evidence that permits extraction of signal from noise (large lists of genes), and prioritization of top candidates; and (vi) used to form the basis of prediction score algorithm based.
[00050] Integration of animal model and human data was used as a way of reducing the false- positives inherent in each approach and helping identify true biomarker molecules. Gene expression differences were measured in fresh blood samples from patients with bipolar disorder (manic- depressive illness) that have low mood vs. those that have high mood at the time of the blood draw. Separately, changes in gene expression were measured in the brains and bloods of a mouse pharmacogenomic model of bipolar disorder. Human blood gene expression data was integrated with animal model gene expression data, human genetic linkage/association data, and human postmortem data for cross-validating and prioritizing findings.
[00051 ] Gene expression changes in specific brain regions and blood from a pharmacogenomic animal model were used as cross-validators to identify human blood biomarkers for mood disorders. Pharmacogenomic mouse model of relevance to bipolar disorder includes treatments with an agonist of the illness/bipolar disorder-mimicking drug (methamphetamine) and an antagonist of the illness/ bipolar disorder-treating drug (valproate). The pharmacogenomic approach is a tool for tagging genes that may have pathophysiological relevance. As an added advantage, some of these genes may be involved in potential medication effects present in human blood data (FIG. 2).
[00052] In an aspect, human whole blood gene expression studies were initially performed in a primary cohort of bipolar subjects. Whole blood was used as a way of minimizing potential artifacts related to sample handling and separation of individual cell types, and also as a way of having a streamlined approach that lends itself well to scalability, future large scale studies in the field, and easy applicability in clinical laboratory settings and doctor's offices. Genes that were differentially expressed in low mood vs. high mood subjects were compared with: 1) the results of animal model brain and blood data, as well as 2) human genetic linkage/association data, and 3) human postmortem brain data, as a way of cross-validating the findings, prioritizing them, and identifying a short list of high probability biomarker genes (FIGS. 2A and 3).
[00053] A focused approach was used to analyze discrete quantitative phenotypic item (phene) — a Visual-Analog Scale (VAS) for mood. This approach avoids the issue of corrections for multiple comparisons that would arise if one were to look in a discovery fashion at multiple phenes in a comprehensive phenotypic battery (PhenoChipping) changed in relationship with all genes on a GeneChip microarray. Larger sample cohorts would be needed for the latter approach.
[00054] A panel of a subset of top candidate biomarker genes for mood state identified by the approach described herein was then used to generate a prediction score for mood state (low mood vs. high mood). This prediction score was compared to the actual self-reported mood scores from
bipolar subjects in the primary cohort (FIG. 4). This panel of mood biomarkers and prediction score were also examined in a separate independent cohort of psychotic disorders patients for which gene expression data and mood state data (FIG.5) were obtained, as well as in a second independent bipolar cohort (FIG.6).
[00055] Sample size for human subjects (n=29 for the primary bipolar cohort, n= 30 for the psychotic disorders cohort, n= 19 for the secondary bipolar cohort) is comparable to the size of cohorts for human postmortem brain gene expression studies in the field. Live donor blood samples instead of postmortem donor brains were studied, with the advantage of better phenotypic characterization, more quantitative state information, and less technical variability. This approach also permits repeated intra-subject measures when the subject is in different mood states.
[00056] The experimental approach for detecting gene expression changes relies on a well- established methodology — oligonucleotide microarrays. To avoid the possibility that some of the gene expression changes detected from a single biological experiment are biological or technical artifacts, the analyses described herein were designed to minimize the likelihood of having false positives, even at the expense of potentially having false negatives, due to the high cost in time and resources of pursuing false leads.
[00057] For the animal model work, using isogenic mouse strain affords a suitable control baseline of saline injected animals for the drug-injected animals. Three independent de novo biological experiments were performed, at different times, with different batches of mice. This overall design is geared to factor out both biological and technical variability. It is to be noted that the concordance between reproducible microarray experiments using the latest generations of oligonucleotide microarrays and other methodologies such as quantitative PCR, with their own attendant technical limitations, is estimated to be over 90%. For the human blood samples differential gene expression analyses, which are the results of single biological experiments, it has to be noted that the approach described herein used a very restrictive and technically robust, all or nothing induction of gene expression (change from Absent Call (A) to Present Call (P)). It is possible that not all biomarker genes for mood will show this complete induction related to state, but rather some will show modulation in gene expression levels, and are thus missed by a stringent filtering approach. Moreover, given the genetic heterogeneity and variable environmental exposure, it is possible, indeed likely, that not all subjects will show changes in all the biomarker genes.
[00058] To identify candidate biomarker genes, two stringency thresholds were used: changes in
75% of subjects, and in 60% of subjects with low mood vs. high mood. Moreover, the approach, as described herein, is predicated on the existence of multiple cross-validators for each gene that is called a candidate biomarker (FIG. 2A): 1) is it changed in human blood, 2) is it changed in animal model brain, 3) is it changed in animal model blood, 4) is it changed in postmortem human brain, and 5) does it map to a human genetic linkage locus. All these lines of evidence are the result of independent experiments. The virtues of this networked Bayesian approach are that, if one or
another of the nodes (lines of evidence) becomes questionable/non-functional upon further evidence in the field, the network is resilient and maintains functionality. Additional lines of evidence may move certain genes in the prioritization scoring. Using approaches described herein, a small number of genes were identified and prioritized as top biomarkers, out of the over 40,000 transcripts (about half of which are detected as Present in each subject) measured by the microarrays that were used.
[00059] A validation of the novel and non-obvious approach described herein is the fact that the biomarker panel showed sensitivity and specificity, of a comparable nature, in both independent replication cohorts (psychotic disorder cohort and secondary bipolar cohort). Thus, the approach of using a visual analog scale phene reflecting an internal subjective experience of well being or distress (as opposed to more complex and disease specific state/trait clinical instruments), and looking at extremes of state combined with robust differential expression based on A/P calls, and Convergent Functional Genomics prioritization, is able to identify state biomarkers for mood, that are, at least in part, independent of specific diagnoses or medications. Nevertheless, a comparison with existing clinical rating scales (FIG. 6), actimetry and functional neuroimaging, as well as analysis of biomarker data using such instruments may be of interest, as a way of delineating state vs. trait issues, diagnostic boundaries or lack thereof, and informing the design of clinical trials that may incorporate clinical and biomarker measures of response to treatment.
[00060] Human blood gene expression changes may be influenced by the presence or absence of both medications and drugs of abuse. While access to the subject's medical records was available and clinical information as part of the informed consent for the study, medication non-compliance, on the one hand, and substance abuse, on the other hand, are not infrequent occurrences in psychiatric patients. That medications and drugs of abuse may have effects on mood state and gene expression is in fact being partially modeled in the mouse pharmacogenomic model, with valproate and methamphetamine treatments respectively. The association of blood biomarkers with mood state is analyzed, regardless of the proximal causes, which could be diverse (see FIG. 2B). The performance the biomarkers identified herein can also be analyzed at a protein level, in larger cohorts of both genders, in different age groups, and in theragnostic settings- measuring responses to specific treatments/medications.
[00061 ] A subset of top candidate biomarker genes include five genes involved in myelination (
Mbp, Edg2, Mag, Pmp22 and Ugt8), six genes involved in growth factor signaling ( Fgfrl, Fzd3, Erbb3, Igfbp4, Igfbpό), one gene involved in light transduction (PDE6D), and one gene involved in neurofilaments (Nefh). These genes were selected as having a line of evidence (CFG) score of 4 or higher (Table 3). That means, in addition to the human blood data, these genes have at least two other independent lines of evidence implicating them in mood disorders and/or concordance of expression in human brain and blood. Using this cutoff score, about 13 genes (FIG. 3), all of which have evidence of differential expression in human postmortem brains from mood disorder patients.
[00062] It is intriguing that genes which have a well-established role in brain functioning may show changes in blood in relationship to psychiatric symptoms state (FIG. 3, Table 3 and Table 7), and moreover that the direction of change may be concordant with that found in human postmortem brain studies. It is possible that trait promoter sequence mutations or epigenetic modifications influence expression in both tissues (brain and blood), and that state dependent transcription factor changes that modulate the expression of these genes may be contributory as well.
[00063] The data provided herein demonstrate that genes involved in brain infrastructure changes
(myelin, growth factors) are prominent players in mood disorders, and are reflected in the blood profile. Myelin abnormalities have emerged as a common if perhaps non-specific denominator across a variety of neuropsychiatric disorders. For exmaple, Mbp, is a top scoring candidate biomarker (FIG. 3), associated with high mood state. The data provided herein regarding insulin growth factor signaling changes may provide an underpinning for the co-morbidity with diabetes and metabolic syndrome often encountered in mood disorder patients. These changes may be etiopathogenic, compensatory mechanisms, side-effects of medications, or results of illness - induced lifestyle changes (FIG. 2B).
[00064] The fact that many of the biomarkers identified are associated with a low mood state
(depression) as opposed to high mood state (FIG. 3 and Table 3) indicates that depression may have more of an impact on blood gene expression changes, perhaps through a neuro-endocrine- immunological axis, as part of a whole-body reaction to a perceived hostile environment.
[00065] Some of the candidate biomarker genes identified herein have no previous evidence for involvement in mood disorders (Tables 3 and 7). They merit further exploration in genetic candidate gene association studies, as well as comparison with emerging results from whole -genome association studies of bipolar disorder and depression. If needed, the composition of biomarker panels for mood can be refined or changed for different sub-populations, depending upon the availability of additional evidence. Panels containing different number of biomarkers and different biomarkers can be developed using the guidelines described herein and from the biomarkers identified herein. A large number of the biomarkers that would be of use in different panels and permutations are already present in the complete list of candidate biomarker genes identified (Tables 3 and 7).
[00066] An interrogation of a connectivity map with a signature query composed of the genes in a panel of top biomarkers for low mood and high mood revealed that sodium phenylbutyrate exerts the most similar effects to high mood, and novobiocin the most similar effects to low mood (FIG. 5). Sodium phenylbutirate is a medication used to treat hyperammonemia that also has histone deacetylase (HDAC) properties, cell survival and anti-apoptotic effects. The mood stabilizer drug valproate, also a HDAC inhibitor, as well as sodium phenylbutirate and another HDAC inhibitor, trichostatin A, were shown to induce alpha-synuclein in neurons through inhibition of HDAC and that this alpha-synuclein induction was critically involved in neuroprotection against glutamate
excitotoxicity. Human postmortem brain studies, as well as animal model and clinical studies have implicated glutamate abnormalities and histone deacetylase modulation as therapeutic targets in mood disorders. Novobiocin is an antibiotic drug that also has anti-tumor activity and apoptosis- inducing properties, through Hsp90 inhibition of Akt kinase an effect opposite to that of the valproate, trichostatin A and sodium phenylbutyrate (Table 6).
[00067] This connectivity map analysis with a mood panel genes provides an interesting external biological cross-validation for the internal consistency of the biomarker approach, as well as illustrates the utility of the connectivity map for non-hypothesis driven identification of novel drug treatments and interventions.
[00068] The results provided herein are consistent with a trophicity model for genes involved in mood regulation: cell survival and proliferation associated with high mood, and cell shrinkage and death associated with low mood. This perspective is both of evolutionary interest and pragmatic clinical importance. Nature may have selected primitive cellular mechanisms for analogous higher organism level-functions: survival and expansion in favorable, mood-elevating environments, withdrawal and death (apoptosis) in unfavorable, depressogenic environments. In this view, suicide is the organismal equivalent of cellular apoptosis (programmed cell death). Pragmatically, the results point to an unappreciated molecular and therapeutic overlap between two broad areas of medicine: mood disorders and cancer. This overlap is relevant for the clinical co-morbidity of mood disorders and cancer, as well as for empirical studies to evaluate the use of mood-regulating drugs in cancer, and of cancer drugs in mood disorders.
[00069] In clinical practice there is a high degree of overlap and co-morbidity between mood disorders, psychosis and substance abuse.The data in bipolar and psychotic disorder cohorts point to the issue of heterogeneity, overlap and interdependence of major psychiatric syndromes as currently defined by DSM-IV, and the need for a move towards comprehensive empirical profiling and away from categorical diagnostic classifications.
[00070] There are to date no reliable clinical laboratory blood tests for mood disorders. A translational convergent approach is disclosed herein to identify and prioritize blood biomarkers of mood state. Data demonstrate that blood biomarkers are effective in offering an unexpectedly informative window into brain functioning and disease state. Panels of such biomarkers may serve as a basis for objective clinical laboratory tests, a longstanding unmet need for psychiatry. Biomarker-based tests are extremely valuable for early intervention and prevention efforts, as well as monitoring response to various treatments. In conjunction with other relevant clinical information, biomarker tests play a desirable part of personalizing treatment to increase effectiveness and avoid adverse reactions- personalized medicine in psychiatry. Moreover, the biomarkers identified herein are useful for identifying or screening new neuropsychiatric drugs, at both a pre-clinical and clinical (Phase I, II and III) stages of the process.
[00071 ] Because brain is a highly specialized organ, it is not expected that the genes expressed in the brain would be present in the blood. Expression products of genes (e.g., RNA and protein) are generally tissue specific and are not expected or predicted to be expressed in an unrelated tissue., e.g., blood. Therefore, the finding that certain markers are expressed in blood and are predictable for mood disorder in patients is surprising and non-obvious. Not all markers differentially expressed in blood and are associated with predicting/diagnosing mood disorder are expressed in the brain. Similarly, not all genes that are differentially expressed in brain are expressed in blood for predicting/diagnosing mood disorder.
[00072] Human postmortem brain gene expression studies are generally susceptible to the issue of being underpowered, due to uncertainty of diagnosis and difficulty of accrual of large well- characterized cohorts, as well as due to genetic heterogeneity and the effect of variable environmental exposure on gene expression. Moreover, postmortem work artifacts (agonal interval, pH and tissue degradation) may influence gene expression changes.
[00073] For example, the data presented herein has not found reliable blood evidence for some of the top candidate genes derived from postmortem work, such as: Grial(glutamate receptor, ionotropic, AMPAl (alpha I)), Grikl (glutamate receptor, ionotropic, kainate 1), Gsk3b (glycogen synthase kinase 3 beta) and Arntl aryl hydrocarbon receptor nuclear translocator-like. Conversely, some of the top blood biomarkers identified herein do not appear to have reliable human postmortem brain evidence to date: Btgl (B -cell translocation gene 1, anti-proliferative), Ednrb (endothelin receptor type B), EIo vl5 (ELOVL family member 5, elongation of long chain fatty acids), and Trpcl (transient receptor potential cation channel, subfamily C, member 1).
[00074] A plurality of high probability blood candidate biomarker genes for mood state is identified.
In an aspect, a select panel of biomarkers include for example, five genes involved in myelination ( Mbp, Edg2, Mag, Pmp22 and Ugt8), six genes involved in growth factor signaling ( Fgfrl, Fzd3, Erbb3, Igfbp4, Igfbpό), one gene involved in light transduction (PDE6D), and one gene involved in neurofilaments (Nefh). . These genes have evidence of differential expression in human postmortem brains from mood disorder patients.
[00075] A predictive score developed based on a panel of 10 top candidate biomarkers, designated herein as BioM-10 (5 for high mood, 5 for low mood) shows specificity and sensitivity for high mood and low mood states.
[00076] A parallel profiling of cognitive and affective state was performed to investigate: (i) relationships between phenotypic items ("phenes"), including with objective motor measures, and (ii) relationships between subjects. This approach is useful in advancing current diagnostic classifications, and indicates that a combinatorial building-block structure underlies many psychiatric syndromes. The adaptation of microarray-based informatic tools for phenotypic analysis facilitates direct integration with gene expression profiling of blood in the same individuals, a strategy for molecular biomarker identification. Empirically derived clusterings of (endo)phenotypes
and of patients provide a basis for genetic, pharmacological, and imaging research, as well as clinical practice.
[00077] In an aspect, some of the candidate genes included in a panel of biomarkers used herein, have no previous evidence for involvement in mood disorders other than being mapped to bipolar genetic linkage loci (Table 3). These genes constitute novel candidate genes for bipolar disorder and depression. The composition of biomarker panels for mood can be refined or changed for different sub-populations. Panels containing different number of biomarkers and different biomarkers can be developed using the guidelines described herein and from the complete list of more than 600 biomarkers identified (Tables 3 and 7).
[00078] Any number of biomarkers can be used as a panel for diagnosis. The panel may contain equal number of biomarkers for high and low mood, or different number of biomarkers associated with low mood than high mood. The panel may be tested as a microarray or as any form of diagnostic analysis.
[00079] In the present disclosure, gene expression changes in specific brain regions and blood of animal models developed were studied to identify one or more of the biomarkers disclosed herein. Data were obtained from a pharmacogenomic mouse model of bipolar (involving treatments with a stimulant — methamphetamine, and a mood stabilizer — valproate) as a discovery engine and cross- validator for the identification of potential peripheral blood biomarkers (see Ogden et al., (2004), Candidate genes, pathways and mechanisms for bipolar (manic-depressive) and related disorders: an expanded convergent functional genomics approach. MoI Psychiatry 9(11): 1007-29.). Data from other animal models of bipolar disorder, such as genetic models, can be used (see Le-Niculescu et al. (2008) Phenomic, convergent functional genomic and biomarker studies in a stress-reactive genetic animal model of bipolar disorder and co-morbid alcoholism. American Journal of Medical Genetics Part B (Neuropsychiatric Genetics) 147(2): 134-66.
[00080] In an embodiment, a comprehensive analysis of: (i) fresh human blood gene expression data tied to illness state (quantitative measures of symptoms), (ii) cross-validation of blood gene expression profiling in conjunction with brain gene expression studies in animal models presenting key features of bipolar disorder, and (iii) integration of the results in the context of the available human genetic linkage/association and postmortem brain findings in the field is provided.
[00081 ] In an aspect, human blood gene expression studies were carried out in a primary group of bipolar subjects with low mood states and high mood states, as well as in a group of subjects with psychotic disorders (schizoaffective disorder, schizophrenia, and substance induced psychotic disorder), and in a second, independent, group of subjects with bipolar disorder. Genes that were differentially expressed in low mood vs. high mood subjects were compared with (i) the results of animal model data, (ii) human genetic linkage/association data and (iii) human postmortem brain data to cross-validate the results, prioritizing the genes, and identifying a short list of high
probability candidate biomarker genes. A panel of candidate biomarker genes identified by this approach was then used to generate a prediction score for mood state (low mood/depression vs. high mood/mania). This prediction score was compared to the actual self -reported mood scores from human subjects. The prediction score developed by the analysis of convergent data provided a highly correlative basis for the diagnosis of mood state.
[00082] In an embodiment, a panel of biomarkers illustrated in Table 3 is suitable. These biomarkers include Mbp, Edg2, Fgfrl, Fzd3, Mag, Pmp22, Ugt8, Erbb3, Igfbp4, Igfbpό, Pdeόd , Ptprm, Nefh, Atp2cl, Atxnl, Btgl, C6orfl82, Dicer 1, Dnajcό, Ednrb, Elovl5, Gnal, Klf5, Lin7a, Manea, Nupll, Pdeόb, Slc25a23, Synpo, Tgm2, Tjp3, Tpd52, Trpcl, Bclafl, Gosr2, Rdx, Wdr34, Bic, C8orf42, Dock9, Hrasls, Ibrdc2, P2ryl2, Speed, Vil2.
[00083] In an embodiment, a panel of about 10 biomarkers, e.g., Mbp, Edg2, Fgfrl, Fzd3, Mag,
Pmp22, Ugt8, Erbb3, Igfbp4, and Igfbpό, is suitable for diagnosing or predicting mood disorder.
[00084] In an embodiment, a panel of biomarkers include for example, Mbp, Edg2, Fzd3, Atxnl, and Ednrb that are increased in high mood (mania) condition.
[00085] An embodiment of a first sub-group of markers that are used for analysis include for example: Mbp, Edg2, Fzd3, Atxnl, Ednrb (markers for high mood) and Fgfrl, Mag, Pmp22, Ugt8, Erbb3 (markers for low mood). An embodiment includes a second sub-group e.g., Pde9a, Plxndl, Camk2d, Dio2, Lepr (markers for high mood) and Igfbp4, Igfbpό, Pdeόd, Ptprm, Nefh Atp2cl (markers for low mood). An embodiment includes a third sub-group e.g., Myom2, Nfix, Nt5m, Or7el04p, Rrpl (markers for high mood) and Atp2cl, Btgl, Elov5, Lrrcδb, Dicerl, Dnajcό (markers for low mood). An embodiment includes a fourth sub-group e.g., Sept2, Sfrs4, Sla2, Tex261, Ube2i (markers for high mood) and Gnal, Klf5, Lin7a, Manea, Nupll (markers for low mood). An embodiment includes a fifth sub-group e.g., Usp7, Zdhhc4, Znfl69, Cuedcl, Bivm (markers for high mood) and Pdeόb, Slc25a23, Synpo, Tgm2, Tjp3 (markers for low mood). An embodiment includes a sixth sub-group e.g., Hla-dqal, C20orf94, C21orf56, F1J10986, Loc91431 (markers for high mood), Tpd52, Trpcl, Phldal, Znf502, Amn (markers for low mood) or a combination of one or more of the sub-goups 1-6 disclosed herein. Sub-groups 1-5 constitute a representative example and any number of sub-groups that has about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 200, 300, 400, 500, 600, or more markers selected from Table 7.
[00086] An embodiment of a first sub-group of markers that are used for analysis include for example: Mbp, Edg2, Fzd3, Atxnl, Ednrb (markers for high mood), Fgfrl, Mag, Pmp22, Ugt8, Erbb3 (markers for low mood); second subgroup includes for example: Pde9a, Plxndl, Camk2d, Dio2, Lepr (markers for high mood), Igfbp4, Igfbpό, Pdeόd, Ptprm, Nefh, (markers for low mood); third subgroup includes for example: Myom2, Nfix, Nt5m, Or7el04p, Rrpl (markers for high mood), Btgl, Elov5, Lrrcδb, Dicerl, Atp2cl, (markers for low mood); fourth subgroup includes for example: Sept2, Sfrs4, Sla2, Tex261, Ube2i (markers for high mood), Gnal, Klf5, Lin7a, Manea,
Dnajcό (markers for low mood); fifth subgroup includes for example: Usp7, Zdhhc4, Znfl69, Cuedcl, Bivm (markers for high mood), Pdeόb, Slc25a23, Synpo, Tgm2, Nupll (markers for low mood); and sixthy subgroup includes for example: Hla-dqal, C20orf94, C21orf56, Vil2, Loc91431 (markers for high mood), Tpd52, Trpcl, Phldal, Tjp3, Amn (markers for low mood) or a combination of one or more of the sub-goups 1-6 disclosed herein. Sub-groups 1-5 constitute a representative example and any number of sub-groups that has about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 200, 300, 400, 500, 600, or more markers selected from Tables 3 and 7.
[00087] A panel of 36 biomarkers, as illustrated in an example described herein, is a suitable subset that is useful in diagnosing a mood disorder. Larger subsets that includes for example, 150, 200, 250, 300, 350, 400, 450, 500, 600 or about 700 markers are also suitable. Smaller subsets that include high-value markers including about 2, 5, 10, 15, 20, 25, 50, 75, and 100 are also suitable. A variable quantitative scoring scheme can be designed using any standard algorithm, such as a variable selection or a subset feature selection algorithms can be used. Both statistical and machine learning algorithms are suitable in devising a frame work to identify, rank, and analyze association between marker data and phenotypic data (e.g., mood disorders).
[00088] In an embodiment, a prediction score for each subject is derived based on the presence or absence of e.g., 10 biomarkers of the panel in their blood. Each of the 10 biomarkers gets a score of 1 if it is detected as "present" (P) in the blood form that subject, 0.5 if it is detected as "marginally present" (M), and 0 if it is called "absent" (A). The ratio of the sum of the high mood biomarker scores divided by the sum of the low mood biomarker scores is multiplied by 100, and provides a prediction score. If the ratio of high biomarker genes to low mood biomarker genes is 1 , i.e. the two sets of genes are equally represented, the mood prediction score is 1x100=100. The higher this score, the higher the predicted likelihood that the subject will have high mood. The predictive score was compared with actual self-reported mood scores in a primary cohort of subjects with a diagnosis of bipolar mood disorder. A prediction score of 100 and above had a 84.6 % sensitivity and a 68.8 % specificity for predicting high mood. A prediction score below 100 had a 76.9 % sensitivity and 81.3 % specificity for predicting low mood. The term "present" indicates that a particular biomarker is expressed to a detectable level, as determined by the technique used. For example, in an experiment involving a microarray or gene chip obtained from a commercial vendor Affymetrix (Santa Clara, CA), the embedded software rendered a "present" call for that biomarker. The term "present" refers to a detectable presence of the transcript or its translated protein/peptide and not necessarily reflects a relative comparion to for example, a sample from a normal subject. In other words, the mere presence or absence of a biomarker is assigned a value, e.g., 1 and a prediction score is calculated as described herein. The term "marginally present: refers to border line
expression level that may be less intense than the "present" but statistically different from being marked as "absent" (above background noise), as determined by the methodology used.
[00089] In an embodiment, a prediction score based on differential expression (instead of "present",
"absent") is used. For example, if a subject has a plurality of markers for high or low mood are differentially expressed, a prediction based on the differential expression of markers is determined. Differential expression of about 1.2 fold or 1.3 or 1.5 or 2 or 3 or 4 or 5-fold or higher for either increased or decreased levels can be used. Any standard statistical tool such as ANOVA is suitable for analysis of differential expression and association with high or low mood diagnosis or prediction.
[00090] A prediction based on the analysis of either high or low mood markers alone (instead of a ratio of high versus low mood markers) may also be practiced. If a plurality of high mood markers (e.g., about 6 out of 10 tested) are differentially expressed to a higher level compared to the low mood markers (e.g., 4 out of 10 tested), then a prediction or diagnosis of high mood status can be made by analyzing the expression levels of the high mood markers alone without factoring the expression levels of the low mood markers as a ratio.
[00091 ] In an embodiment, a detection algorithm uses probe pair intensities to generate a detection p-value and assign a Present, Marginal, or Absent call. Each probe pair in a probe set is considered as having a potential vote in determining whether the measured transcript is detected (Present) or not detected (Absent). The vote is described by a value called the Discrimination score [R]. The score is calculated for each probe pair and is compared to a predefined threshold Tau. Probe pairs with scores higher than Tau vote for the presence of the transcript. Probe pairs with scores lower than Tau vote for the absence of the transcript. The voting result is summarized as a p-value. The greater the number of discrimination scores calculated for a given probe set that are above Tau, the smaller the p-value and the more likely the given transcript is truly Present in the sample. The p-value associated with this test reflects the confidence of the Detection call.
[00092] Regarding detection p-value, a two-step procedure determines the Detection p-value for a given probe set. The Discrimination score [R] is calculated for each probe pair and the discrimination scores are tested against the user-definable threshold Tau. The detection Algorithm assesses probe pair saturation, calculates a Detection p-value, and assigns a Present, Marginal, or Absent call. In an embodiment, the default thresholds of the Affymetrix MAS 5 software were used.
[00093] In spiking experiments by the manufacturer to establish default thresholds (adding of known quantities of test transcripts to a mixture, to measure the sensitivity of the Affymetrix MAS 5 detection algorithm) 80% of spiked transcripts are called Present at a concentration of 1.5 pM. This concentration corresponds to approximately one transcript in 100,000 or 3.5 copies per cell. The false positive rate of making a Present call was roughly 10%, as noted by 90% of the transcripts being called Absent when not spiked into the sample (0 pM concentration).
[00094] The term "predictive" or the term "prognostic" does not imply 100% predictive ability. The use of these terms indicates that subjects with certain characteristics are more likely to experience a particular mood state or clinical outcome than subjects who do not have such characteristics. For example, characteristics that determine the prediction include one or more of the biomarkers for the mood disorder disclosed herein. The phrase "clinical outcome" refers to biological or biochemical or physical or physiological responses to treatments or therapeutic agents that are generally prescribed for that condition compared to a condition would occur in the absence of any treatment. A "clinically positive outcome" does not necessarily indicate a cure, but could indicate a lessening of symptoms experienced by a subject.
[00095] The terms "marker" and "biomarker" are synonymous and as used herein, refer to the presence or absence or the levels of nucleic acid sequences or proteins or polypeptides or fragments thereof to be used for associating or correlating a phenotypic state. A biomarker includes any indicia of the level of expression of an indicated marker gene. The indicia can be direct or indirect and measure over- or under-expression of the gene given the physiologic parameters and in comparison to an internal control, normal tissue or another phenotype. Nucleic acids or proteins or polypeptides or portions thereof used as markers are contemplated to include any fragments thereof, in particular, fragments that can specifically hybridize with their intended targets under stringent conditions and immunologically detectable fragments. One or more markers may be related. Marker may also refer to a gene or DNA sequence having a known location on a chromosome and associated with a particular gene or trait. Genetic markers associated with certain diseases or for pre-disposing disease states can be detected in the blood and used to determine whether an individual is at risk for developing a disease. Levels of gene expression and protein levels are quantifiable and the variation in quantification or the mere presence or absence of the expression may also serve as markers. Using proteins/peptides as biomarkers can include any method known in the art including, without limitation, measuring amount, activity, modifications such as glycosylation, phosphorylation, ADP- ribosylation, ubiquitination, etc., imunohistochemistry (IHC).
[00096] As used herein, "array" or "microarray" refers to an array of distinct polynulceotides, oligonucleotides, polypeptides, or oligopeptides synthesized on a substrate, such as paper, nylon, or other type of membrane, filter, chip, glass slide, or any other suitable solid support. Arrays also include a plurality of antibodies immobilized on a support for detecting specific protein products. There are several microarrays that are commercially available. A microarray may include one or more biomarkers disclosed herein. A panel of about 20 biomarkers as nucleic acid fragments can be included in an array. The nucleic acid fragments may include oligonucleotides or amplified partial or complete nucleotide sequences of the biomarkers. The term "consisting essentially of generally refers to a collection of markers that substantially affects the determination of the disorder and may include other components such as controls. For example, a microarray consists essentially of markers from Table 3.
[00097] In an embodiment, the microarray is prepared and used according to the methods described in U.S. Pat. No. 5,837,832, Chee et al.; PCT application WO95/11995, Chee et al.; Lockhart et al., 1996. Nat Biotech., 14:1675-80; and Schena et al., 1996. Proc. Natl. Acad. Sci. 93:10614-619, all of which are herein incorporated by reference to the extent they relate to methods of making a microarray. Arrays can also be produced by the methods described in Brown et al., U.S. Pat. No. 5,807,522. Arrays and microarrays may be referred to as "DNA chips" or "protein chips." [00098] A variety of clustering methods are available for microarray-based gene expression analysis.
See for example, Shamir & Sharan (2002) Algorithmic approaches to clustering gene expression data. In Current Topics In Computational Molecular Biology (Edited by: Jiang T, Xu Y, Smith T). 2002, 269-300; Tamames et al., (2002): Bioinformatics methods for the analysis of expression arrays: data clustering and information extraction, J Biotechnol, 98:269-283.
[00099] "Therapeutic agent" means any agent or compound useful in the treatment, prevention or inhibition of mood disorder or a mood-related disorder.
[000100] The term "condition" refers to any disease, disorder or any biological or physiological effect that produces unwanted biological effects in a subject.
[000101 ] The term "subject" refers to an animal, or to one or more cells derived from an animal. The animal may be a mammal including humans. Cells may be in any form, including but not limited to cells retained in tissue, cell clusters, immortalized cells, transfected or transformed cells, and cells derived from an animal that have been physically or phenotypically altered.
[000102] Any body fluid of an animal can be used in the methods of the invention. Suitable body fluids include a blood sample (e.g., whole blood, serum or plasma), urine, saliva, cerebrospinal fluid, tears, semen, and vaginal secretions. Also, lavages, tissue homogenates and cell lysates can be utilized.
[000103] Many different methods can be used to determine the levels of markers. For example, protein arrays, protein chips, cDNA microarrays or RNA microarrays are suitable. More specifically, one of ordinary skill in the art will appreciate that in one example, a microarray may comprise the nucleic acid sequences representing genes listed in Table 1. For example, functionality, expression and activity levels may be determined by immunohistochemistry, a staining method based on immunoenzymatic reactions uses monoclonal or polyclonal antibodies to detect cells or specific proteins. Typically, immunohistochemistry protocols include detection systems that make the presence of markers visible (to either the human eye or an automated scanning system), for qualitative or quantitative analyses. Mass-spectrometry, chromatography, real-time PCR, quantitative PCR, probe hybridization, or any other analytical method to determine expression levels or protein levels of the markers are suitable. Such analysis can be quantitative and may also be performed in a high-through put fashion. Cellular imaging systems are commercially available that combine conventional light microscopes with digital image processing systems to perform quantitative analysis on cells and tissues, including immunostained samples. (See e.g. the CAS-200
System (Becton, Dickinson & Co.))- Some other examples of methods that can be used to determine the levels of markers include immunohistochemistry, automated systems, quantitative IHC, semiquantitative IHC and manual methods. Other analytical systems include western blotting, immunoprecipitation, fluorescence in situ hybridization (FISH), and enzyme immunoassays.
[000104] The term "diagnosis", as used in this specification refers to evaluating the type of disease or condition from a set of marker values and/or patient symptoms where the subject is suspected of having a disorder. This is in contrast to disease predisposition, which relates to predicting the occurrence of disease before it occurs, and the term "prognosis", which is predicting disease progression in the future based on the marker levels/patterns.
[000105] The term "correlating," as used in this specification refers to a process by which one or more biomarkers are associated to a particular disease state, e.g., mood disorder. In general, identifying such correlation or association involves conducting analyses that establish a statistically significant association- and/or a statistically significant correlation between the presence (or a particular level) of a marker or a combination of markers and the phenotypic trait in the subject. An analysis that identifies a statistical association (e.g., a significant association) between the marker or combination of markers and the phenotype establishes a correlation between the presence of the marker or combination of markers in a subject and the particular phenotype being analyzed.
[000106] This relationship or association can be determined by comparing biomarker levels in a subject to levels obtained from a control population, e.g., positive control— diseased (with symptoms) population and negative control— disease-free (symptom-free) population. The biomarkers disclosed herein provide a statistically significant correlation to diagnosis at varying levels of probability. Subsets of markers, for example a panel of about 20 markers, each at a certain level range which are a simple threshold, are said to be correlative or associative with one of the disease states. Such a panel of correlated markers can be then be used for disease detection, diagnosis, prognosis and/or treatment outcome. Preferred methods of correlating markers is by performing marker selection by any appropriate scoring method or by using a standard feature selection algorithm and classification by known mapping functions. A suitable probability level is a 5% chance, a 10% chance, a 20% chance, a 25% chance, a 30% chance, a 40% chance, a 50% chance, a 60% chance, a 70% chance, a 75% chance, a 80% chance, a 90% chance, a 95% chance, and a 100% chance. Each of these values of probability is plus or minus 2% or less. A suitable threshold level for markers of the present invention is about 25 pg/mL, about 50 pg/mL, about 75 pg/mL, about 100 pg/mL, about 150 pg/mL, about 200 pg/mL, about 400 pg/mL, about 500 pg/mL, about 750 pg/mL, about 1000 pg/mL, and about 2500 pg/mL.
[000107] Prognosis methods disclosed herein that improve the outcome of a disease by reducing the increased disposition for an adverse outcome associated with the diagnosis. Such methods may also be used to screen pharmacological compounds for agents capable of improving the patient's prognosis, e.g., test agents for mood disorders.
[000108] The analysis of a plurality of markers, for example, a panel of about 20 or 10 markers may be carried out separately or simultaneously with one test sample. Several markers may be combined into one test for efficient processing of a multiple of samples. In addition, one skilled in the art would recognize the value of testing multiple samples (for example, at successive time points) from the same individual. Such testing of serial samples may allow the identification of changes in marker levels over time, within a period of interest, or in response to a certain treatment.
[000109] In another embodiment, a kit for the analysis of markers includes for example, devises and reagents for the analysis of at least one test sample and instructions for performing the assay. Optionally, the kits may contain one or more means for using information obtained from marker assays performed for a marker panel to diagnose mood disorders. Probes for markers, marker antibodies or antigens may be incorporated into diagnostic assay kits depending upon which markers are being measured. A plurality of probes may be placed in to separate containers, or alternatively, a chip may contain immobilized probes. In an embodiment, another container may include a composition that includes an antigen or antibody preparation. Both antibody and antigen preparations may preferably be provided in a suitable titrated form, with antigen concentrations and/or antibody titers given for easy reference in quantitative applications.
[000110] The kits may also include a detection reagent or label for the detection of specific reaction between the probes provided in the array or the antibody in the preparation for immunodetection. Suitable detection reagents are well known in the art as exemplified by fluorescent, radioactive, enzymatic or otherwise chromogenic ligands, which are typically employed in association with the nucleic acid, antigen and/or antibody, or in association with a secondary antibody having specificity for first antibody. Thus, the reaction is detected or quantified by means of detecting or quantifying the label. Immunodetection reagents and processes suitable for application in connection with the novel methods of the present invention are generally well known in the art.
[000111] The reagents may also include ancillary agents such as buffering agents and protein stabilizing agents, e.g., polysaccharides and the like. The diagnostic kit may further include where necessary agents for reducing background interference in a test, agents for increasing signal, software and algorithms for combining and interpolating marker values to produce a prediction of clinical outcome of interest, apparatus for conducting a test, calibration curves and charts, standardization curves and charts, and the like.
[000112] In some embodiments, the methods of correlating biomarkers with treatment regimens can be carried out using a computer database. Computer-assisted methods of identifying a proposed treatment for mood disorders are suitable. The method involves the steps of (a) storing a database of biological data for a plurality of patients, the biological data that is being stored including for each of said plurality of patients (i) a treatment type, (ii) at least one marker associated with a mood disorder and (iii) at least one disease progression measure for the mood disorder from which treatment efficacy can be determined; and then (b) querying the database to determine the
dependence on the marker of the effectiveness of a treatment type in treating the mood disorder, to thereby identify a proposed treatment as an effective treatment for a subject carrying the marker correlated with the mood disorder.
[000113] In an embodiment, treatment information for a patient is entered into the database (through any suitable means such as a window or text interface), marker information for that patient is entered into the database, and disease progression information is entered into the database. These steps are then repeated until the desired number of patients has been entered into the database. The database can then be queried to determine whether a particular treatment is effective for patients carrying a particular marker, not effective for patients carrying a particular marker, and the like. Such querying can be carried out prospectively or retrospectively on the database by any suitable means, but is generally done by statistical analysis in accordance with known techniques, as described herein.
EXAMPLES
[000114] The following examples are to be considered as exemplary and not restrictive or limiting in character and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
EXAMPLE 1 Experimental framework for identification of biomarkers used in diagnosis of mood disorders
[000115] Gene expression changes in specific brain regions and blood from a pharmacogenomic animal model were used as cross-validators for identification of potential human blood biomarkers. Pharmacogenomic mouse model of relevance to bipolar disorder consists of treatments with an agonist of the illness/bipolar disorder-mimicking drug (methamphetamine) and an antagonist of the illness/ bipolar disorder-treating drug (valproate). The pharmacogenomic approach is a tool for tagging genes that may have pathophysiological relevance.
[000116] Human blood gene expression studies were carried out in a cohort of bipolar subjects.
Genes that were differentially expressed in low mood vs. high mood subjects were compared with: 1) the results of the animal model brain and blood data, as well as 2) published human genetic linkage/association data, and 3) human postmortem brain data, as a way of cross-validating the findings, prioritizing them, and coming up with a short list of high probability candidate biomarker genes (FIGS. 2A and 3).
[000117] A Visual-Analog Scale (VAS) for mood was used for the scoring analysis. This approach avoids the issue of corrections for multiple comparisons that would arise if multiple symptom (phenotypic) socres (i.e. "phenes") were analyzed in a comprehensive phenotypic battery changed in relationship with all genes on a GeneChip microarray. Larger sample cohorts would be needed for the latter approach.
[000118] A panel of top candidate biomarker genes for mood state identified was then used to generate a prediction score for mood state (low mood vs. high mood). This prediction score was
compared to the actual self-reported mood scores from bipolar subjects (FIG. 4). This panel of mood biomarkers and prediction score were examined in a separate independent cohort of psychotic disorders patients for which gene expression data and mood state data is available (FIG. 5), and in a second independent cohort of bipolar disorder subjects (FIG.6).
[000119] Sample size for human subjects (n=29 for the bipolar cohort, n= 30 for the psychotic disorders cohort) is comparable to the size of cohorts for human postmortem brain gene expression studies. Live donor blood samples were used instead of postmortem donor brains, with the advantage of better phenotypic characterization, more quantitative state information, and less technical variability.
[000120] For the animal model work, isogenic mouse strain was used. Three independent de novo biological experiments were performed, at different times, with different batches of mice. This overall design is geared to factor out both biological and technical variability. Concordance between reproducible microarray experiments using the latest generations of oligonucleotide microarrays and other methodologies such as quantitative PCR, with their own attendant technical limitations, is estimated to be over 90%. For the human blood samples gene expression analyses, which are the results of single biological experiments, a very restrictive, all or nothing induction of gene expression (change from Absent Call to Present Call). It is possible that not all biomarker genes for mood may show this complete induction related to state, but rather some may show modulation in gene expression levels, and are thus missed by this filtering. Moreover, given the genetic heterogeneity and variable environmental exposure, it is possible, indeed likely, that not all subjects may show changes in all the biomarker genes. Hence two stringency thresholds were used: changes in 75% of subjects, and in 60% of subjects with low mood vs. high mood. This approach is predicated on the existence of multiple cross-validators for each gene that is called a candidate biomarker (FIG. 2B): 1) is it changed in human blood, 2) is it changed in animal model brain, 3) is it changed in animal model blood, 4) is it changed in postmortem human brain, and 5) does it map to a human genetic linkage locus. All these lines of evidence are the result of independent experiments.
[000121 ] Human blood gene expression changes may be influenced by the presence or absence of both medications and drugs of abuse. That medications and drugs of abuse may have effects on mood state and gene expression is in fact being partially modeled in the mouse pharmacogenomic model, with valproate and methamphetamine treatments respectively. It is the association of blood biomarkers with mood state that is the primary purpose of this analysis, regardless of the proximal causes, which could be diverse (see FIG. 2B).
[000122] The human subjects used in this example included those who were directly recruited, and data collected in other procedures/settings. Blood samples were collected.
[000123] Human data from three independent cohorts of patients are presented. One cohort consists of 29 subjects with bipolar I disorder. The second cohort consists of 30 subjects with psychotic disorders (schizophrenia, schizoaffective disorder, and substance induced psychosis). The third
cohort consists of 19 subjects with bipolar I disorder. The diagnosis is established by a structured clinical interview- Diagnostic Interview for Genetic Studies (DIGS), which has details on the course of illness and phenomenology, and is the scale used by the Genetics Initiative Consortia for both Bipolar Disorder and Schizophrenia.
[000124] Subjects included men and women over 18 years of age. A demographic breakdown is shown in Table 1. Initial studies were focused primarily on a male population, due to the demographics of the catchment area (primarily male in a VA Medical Center), and to minimize any potential gender-related state effects on gene expression, which would have decreased the discriminative power of the analysis for the sample size used. Subjects were recruited from the general population, the patient population at the IU school of Medicine, the Indianapolis VA Medical Center, as well as various facilities that serve people with mental illnesses in Indiana. The subjects were recruited largely through referrals from care providers, the use of brochures left in plain sight in public places and mental health clinics, and through word of mouth. Subjects were excluded if they had significant medical or neurological illness or had evidence of active substance abuse or dependence. All subjects understood and signed informed consent forms before assessments began. All subjects signed an informed consent form detailing the research goals, procedure, caveats and safeguards. Subjects completed diagnostic assessments (DIGS), and then a visual-analog scale for mood (VAS Mood) at the time of blood draw.
[000125] Human blood gene expression experiments and analysis:
[000126] RNA extraction: 2.5-5 ml of whole blood was collected into each PaxGene tube by routine venipuncture. PaxGene tubes contain proprietary reagents for the stabilization of RNA. The cells from whole blood will be concentrated by centrifugation, the pellet washed, resuspended and incubated in buffers containing Proteinase K for protein digestion. A second centrifugation step will be done to remove residual cell debris. After the addition of ethanol for an optimal binding condition the lysate is applied to a silica-gel membrane/column. The RNA bound to the membrane as the column is centrifuged and contaminants are removed in three wash steps. The RNA is then eluted using DEPC-treated water.
[000127] Globin reduction: To remove globin mRNA, total RNA from whole blood is mixed with a biotinylated Capture Oligo Mix that is specific for human globin mRNA. The mixture is then incubated for 15 min to allow the biotinylated oligonucleotides to hybridize with the globin mRNA. Streptavidin Magnetic Beads are then added, and the mixture is incubated for 30 min. During this incubation, streptavidin binds the biotinylated oligonucleotides, thereby capturing the globin mRNA on the magnetic beads. The Streptavidin Magnetic Beads are then pulled to the side of the tube with a magnet, and the RNA, depleted of the globin mRNA, is transferred to a fresh tube. The treated RNA is further purified using a rapid magnetic bead-based purification method. This consists of adding an RNA Binding Bead suspension to the samples, and using magnetic capture to wash and elute the GLOBINclear RNA.
[000128] Sample Labeling: Sample labeling is performed using the Ambion MessageAmp II-
BiotinEnhanced aRNA amplification kit. The procedure is briefly outlined herein and involves the following steps:
[000129] 1. Reverse Transcription to Synthesize First Strand cDNA is primed with the T7 Oligo(dT)
Primer to synthesize cDNA containing a T7 promoter sequence.
[000130] 2. Second Strand cDNA Synthesis converts the single-stranded cDNA into a double- stranded DNA (dsDNA) template for transcription. The reaction employs DNA Polymerase and RNase H to simultaneously degrade the RNA and synthesize second strand cDNA.
[000131 ] 3. cDNA Purification removes RNA, primers, enzymes, and salts that would inhibit in vitro transcription.
[000132] 4. In Vitro Transcription to Synthesize aRNA with Biotin-NTP Mix generates multiple copies of biotin-modified aRNA from the double- stranded cDNA templates; this is the amplification step.
[000133] 5. aRNA Purification removes unincorporated NTPs, salts, enzymes, and inorganic phosphate to improve the stability of the biotin-modified aRNA.
[000134] Microarrays: Biotin labeled aRNA are hybridized to Affymetrix HG-U133 Plus 2.0
GeneChips according to manufacturer's protocols (Affymetrix Inc., Santa Clara, CA). All GAPDH 375' ratios should be less than 2.0 and backgrounds under 50. Arrays are stained using standard Affymetrix protocols for antibody signal amplification and scanned on an Affymetrix Gene Array 2500 scanner with a target intensity set at 250. Present/ Absent calls are determined using GCOS software with thresholds set at default values.
[000135] The human blood gene expression experiments and analysis was performed at two levels: (i) high threshold >75%; 3x enrichment, and (ii) low threshold (>60%; 1.5x enrichment). The animal model data included pharmacogenomic models that involved DBP KO mouse.
[000136] The cross-validation and integration of data from human blood gene expression, mouse models and other mouse and human data were processed through a convergent functional genomics approach.
[000137] For generating the animal model data, standard pharmacogenomic testing methodologies were adopted. All experiments were performed with male C57/BL6 mice, 8 to 12 weeks of age, obtained from Jackson Laboratories (Bar Harbor, ME), and acclimated for at least two weeks in an animal facility prior to any experimental manipulation. The bipolar pharmacogenomic model included Methamphetamine and Valproate treatments in mice (see Ogden et al. (2004)). Briefly, mice were treated by intraperitoneal injection with either single-dose saline, methamphetamine (10 mg/kg), valproate (200 mg/kg), or a combination of methamphetamine and valproate (10 mg/kg and 200 mg/kg respectively). Three independent de novo biological experiments were performed at different times. Each experiment included three mice per treatment condition, for a total of 9 mice per condition across the three experiments.
[000138] RNA extraction and microarray analysis: Standard techniques were used to obtain total
RNA (22 gauge syringe homogenization in RLT buffer) and to purify the RNA (RNeasy mini kit, Qiagen, Valencia, CA) from micro-dissected mouse brain regions. For the human and whole mouse blood RNA extraction, PAXgene blood RNA extraction kit (PreAnalytiX, a QIAGEN/BD company) was used, followed by GLOBINclear™-Human or GLOBINclear™-Mouse/Rat (Ambion/ Applied Biosystems Inc., Austin, TX) to remove the globin mRNA. All the methods and procedures were carried out as per manufacturer's instructions. The quality of the total RNA was confirmed using an Agilent 2100 Bioanalyzer (Agilent Technologies, Palo Alto, CA). The quantity and quality of total RNA was also independently assessed by 260 nm UV absorption and by 260/280 ratios, respectively (Nanodrop spectrophotometer). Starting material of total RNA labeling reactions was kept consistent within each independent microarray experiment.
[000139] For the mouse analysis, blood or brain tissue regions from 3 mice were pooled for each experimental condition, and equal amounts of total RNA extracted from tissue samples or blood was used for labeling and microarray assays. Mouse Genome 430 2.0 arrays (Affymetrix, Santa Clara, CA) were used. The GeneChip™ Mouse Genome 430 2.0 Array contain over 45,000 probe sets that analyze the expression level of over 39,000 transcripts and variants from over 34,000 well- characterized mouse genes. For the human analysis, Affymetrix Human Genome U133 Plus 2.0 GeneChip with over 40,000 genes and ESTs were used. Standard manufacturer's protocols were used to reverse transcribe the messenger RNA and generate biotinlylated cRNA. The amount of cRNA used to prepare the hybridization cocktail was kept constant intra-experiment. Samples were hybridized at 45°C for 17 hours under constant rotation. Arrays were washed and stained using the Affymetrix Fluidics Station 400 and scanned using the Affymetrix Model 3000 Scanner controlled by GCOS software. All sample labeling, hybridization, staining and scanning procedures were carried out as per manufacturer's recommendations.
[000140] Quality control: All arrays were scaled to a target intensity of 1000 using Affymetrix MASv
5.0 array analysis software. Quality control measures including 375' ratios for GAPDH and beta- actin, scaling factors, background, and Q values were within acceptable limits.
[000141 ] Microarray data analysis: Data analysis was performed using Affymetrix Microarray Suite
5.0 software (MAS v5.0). Default settings were used to define transcripts as present (P), marginal (M), or absent (A). For the pharmacogenomic mouse model, a comparison analysis was performed for each drug treatment, using its corresponding saline treatment as the baseline. "Signal," "Detection," "Signal Log Ratio," "Change," and "Change p-value," were obtained from this analysis. Only transcripts that were called Present in at least one of the two samples (saline or drug) intra-experiment, and that were reproducibly changed in the same direction in at least two out of three independent experiments, were analyzed further. For the DBP knock-out mice, a comparison analysis was performed for each KO saline and KO Meth mouse, using WT saline mice as the baseline "Signal," "Detection," "Signal Log Ratio," "Change," and "Change p-value," were
obtained from this analysis. Only transcripts that were called Present in at least one of the two samples in a comparison pair, and that were reproducibly changed in the same direction in at least six out of 9 comparisons, were analyzed further.
EXAMPLE 2 Analysis and identification of biomarkers
[000142] Gene expression profiling studies were performed with peripheral whole blood samples from a primary cohort of 29 human subjects with bipolar I disorder (27 males, 2 females) (Table 1).13 had low self-reported mood scores (below 40) on the Visual-Analog (VAS) Mood Scale (Figure 1), and 13 had high self-reported mood scores (above 60). 3 of them had intermediate mood scores (between 40 and 60). Their mood scores at time of blood collection were used as a way of narrowing the field and identifying candidate biomarker genes for mood. Only t all or nothing gene expression differences were identified by Absent (A) vs. Present (P) Calls in the Affymetrix MAS software. Genes whose expression is detected as Absent in the Low Mood subjects and detected as Present in the High Mood subjects were classified, as being candidate biomarker genes for elevated mood state (mania). Conversely, genes whose expression is detected as Present in the Low Mood subjects and Absent in the High Mood subjects are being classified as candidate biomarker genes for low mood state (depression) (Tables 2 and 3 ). It is possible that some of the genes associated with high mood state or low mood state may not necessarily be involved in the induction of that state, but rather in its suppression as part of a homeostatic regulatory networks or treatment response mechanisms ( similar conceptually to oncogenes and tumor-suppressor genes).
[000143] Two thresholds for analysis of gene expression differences between low mood and high mood (Table 2) were undertaken. First, a high threshold was used, with at least 75% of subjects in a cohort showing a change in expression from Absent to Present between low and high mood ( reflecting an at least 3 fold mood state related enrichment of the genes thus filtered) As psychiatric disorders are clinically and (likely) genetically heterogeneous, with different combinations of genes and biomarkers present in different subgroups, a low threshold was also used, with at least 60% of subjects in a cohort showing a change in expression from Absent to Present between low and high mood ( reflecting an at least 1.5 fold mood state related enrichment of the genes thus filtered). The high threshold identified candidate biomarker genes that are more common for all subjects, with a lower risk of false positives, whereas the lower threshold identified genes that are present in more restricted subgroups of subjects, with a lower risk of false negatives. The high threshold candidate biomarker genes have, as an advantage, a higher degree of reliability, as they are present in at least 75% of all subjects with a certain mood state (high or low) tested. They may reflect common aspects related to mood disorders across a diverse subject population, but may also be a reflection of the effects of common medications used in the population tested, such as mood stabilizers. The low threshold genes may have lower reliability compared to the high threshold, being present in at least
60% of the subject population tested, but, nevertheless, captures more of the diversity of genes and biological mechanisms present in a genetically diverse human subject population.
[000144] By cross-validating with animal model and other human datasets (FIG. 2A) using CFG, a shorter list of genes was identified for which there are external corroborating line of evidence (e.g., human genetic evidence, human postmortem brain data, animal model brain and blood data) linking them to mood disorders (bipolar disorder, depression), thus reducing the risk of false positives. This cross-validation identifies candidate biomarkers that are more likely directly related to the relevant neuropathology, as opposed to being potential artifactual effects or indirect effects of lifestyle, environment, etc.
[000145] Using the approach described herein, out of over 40,000 genes and ESTs on the
Affymetrix Human Genome U133 Plus 2.0 GeneChip, by using the high threshold, in an embodiment, about 21 novel candidate biomarker genes (13 genes with known functions and 7 ESTs) (Table 3), of which 8 had at least one line of prior independent evidence for potential involvement in mood disorders (i.e. CFG score of 3 or above). In addition to the high threshold genes, by using the low threshold, a larger list totaling 661 genes (539 genes and 122 ESTs) (Table 7), of which an additional 24 had at least two lines of prior independent evidence for potential involvement in mood disorders (i.e. CFG score of 3 or above). Of interest, four of the low threshold candidate biomarker genes (Bclafl and Rdx8, Gosr2 and Wdr3413) are changed in expression in the same direction, in lymphoblastoid cell lines (LCLs) from bipolar subjects.
[000146] Making a combined list of all the high value candidate biomarker genes identified as described above- including the high threshold genes with at least on other external line of evidence (8) and of the additional low threshold genes with at least two other external lines of evidence (24), and the low threshold genes with prior LCL evidence (4), a list of 36 candidate biomarker genes for mood, prioritized based on CFG score (Table 3) was developed.
[000147] In an embodiment, selecting the 5 top scoring candidate biomarkers for high mood
(MBP, EDG2, FZD3, ATXNl, EDNRB) and the 5 top scoring candidate biomarkers for low mood (FGFRl, MAG, PMP22, UGT8, ERBB3), a panel of 10 biomarkers for mood disorder was developed that has diagnostic and predictive value.
[000148] To test the predictive value of a panel (e.g, the BioM-10 Mood panel), a cohort of 29 bipolar disorder subjects, containing the 26 subjects (13 low mood, 13 high mood) from which the candidate biomarker data was derived, as well as 3 additional subjects with mood in the intermediate range (self -reported mood scores between 40 and 60) was used. A prediction score for each subject, based on the presence or absence of the 10 biomarkers of the panel in the blood GeneChip data. Each of the 10 biomarkers gets a score of 1 if it is detected as Present (P) in the blood form that subject, 0.5 if it is detected as Marginally Present (M), and 0 if it is called Absent (A). The ratio of the sum of the high mood biomarker scores divided by the sum of the low mood biomarker scores is multiplied by 100, and provides a prediction score. If the ratio of high biomarker genes to low mood biomarker
genes is 1 , i.e. the two sets of genes are equally represented, the mood prediction score is 1x100=100. The higher this score, the higher the predicted likelihood that the subject will have high mood. The predictive score was compared with actual self -reported mood scores in the primary cohort of subjects with a diagnosis of bipolar mood disorder (n=29). A prediction score of 100 and above had a 84.6 % sensitivity and a 68.8 % specificity for predicting high mood. A prediction score below 100 had a 76.9 % sensitivity and 81.3 % specificity for predicting low mood (Table 4A and FIG. 4).
[000149] Table 5 shows a representative sample of biological roles based on ingenuity pathway analysis (IPA) of biological roles categories among the top blood candidate biomarker genes for mood.
[000150] Human blood gene expression analysis was conducted in an independent cohort consisting of 30 subjects with other psychotic disorders (schizophrenia, schizoaffective disorder, substance induced psychosis), who also had mood state scores obtained at the time of the blood draw. The subjects in the psychosis cohort also had a distribution of low (n=9), intermediate (n=7) and high (n=14) mood scores. This cohort was used as a way to verify the predictive power of the mood state biomarker panel, independent of a bipolar disorder diagnosis.
[000151 ] In the psychotic disorders cohort (n=30), with various psychotic disorders diagnoses, a prediction score of 100 and above had a 71.4 % sensitivity and a 62.5 % specificity for predicting high mood. A prediction score below 100 had a 66.7 % sensitivity and 61.9 % specificity for predicting low mood (Table 4B and FIG. 5).
[000152] Human blood gene expression analysis was also conducted in a second independent bipolar disorder cohort, subsequently collected, consisting of 19 subjects. The subjects in the secondary bipolar cohort had a distribution of low (n=6), intermediate (n=3) and high (n=10) mood scores. The second bipolar cohort was used as a replication cohort, to verify the predictive power of the mood state biomarker panel identified by analysis of data from the primary bipolar cohort.
[000153] In the second bipolar cohort (n=19), a prediction score of 100 and above had a 70.0 % sensitivity and a 66.7 % specificity for predicting high mood. A prediction score below 100 had a 66.7 % sensitivity and 61.5 % specificity for predicting low mood (Table 4C and FIG. 6).
[000154] The primary and secondary bipolar mood disorder cohorts are apriori more related and germane to mood state biomarkers identification, but may have blood gene expression changes due at least in part to the common pharmacological agents used to treat bipolar mood disorders. The psychotic disorders cohort may have blood gene expression changes related to mood state irrespective of the diagnosis and the different medication classes subjects with different diagnoses are on (Table 1 and FIG. 2B). The psychosis cohort was also notably different in terms of the ethnic distribution (see Table Ib).
[000155] The MIT/Broad Institute connectivity map was interrogated with a signature query composed of the genes in the BioM -10 Mood panel of top biomarkers for low mood and high mood
(FIG. 5). The effects of drugs in the Connectivity Map database and their effects on gene expression as the effects of high mood or low mood on gene expression. As such, as part of the signature query, the 5 biomarkers for high mood were considered as genes "Increased " by high mood, the 5 biomarkers for low mood were genes "Decreased " by high mood. The analysis revealed that sodium phenylbutyrate exerts the most similar effects to high mood, and novobiocin the most similar effects to low mood. Conventional gene expression analysis may not result in the same set of biomarkers.
[000156] By selecting 5 candidate biomarkers for high mood and 5 candidate biomarkers for low mood, a panel of 10 biomarkers for mood disorder that has diagnostic and predictive value was developed based on the scores of the biomarkers for low and high mood sections. [000157] Thus, the biomarkers identified herein provide quantitative tools for predicting disease states/conditions in subjects suspected of having a mood disorder or in any individual for psychiatric evaluation.
[000158] A meta-analysis of the two bipolar subject cohorts was also conducted. A panel of
10 top biomarkers identified by the meta-analysis was tested for sensitivity and specificity for low and high mood in the two bipolar cohorts (Table 4D). The panel included Edg2, Ednrb, Vil2, Bivm, Camk2d (high mood markers) and Trpcl, Elovl5, Ugt8, Btgl, Nefh (low mood markers). A number of new biomarker genes revealed only in the meta-anlysis were identified (see Table 3).
EXAMPLE 3
Cross-validation and integration using convergent functional genomics approaches to identify and prioritize biomarkers for mood disorders
[000159] The identities of transcripts were established using NetAFFX™ to correlate the GeneChip® array results with array design and annotation information (Affymetrix, Santa Clara, CA), and confirmed by cross-checking the target mRNA sequences that had been used for probe design in the Mouse Genome 430 2.0 Array GeneChip® or the Affymetrix Human Genome Ul 33 Plus 2.0 GeneChip® with the GenBank database. Where possible, identities of ESTs were established by BLAST searches of the nucleotide database. A National Center for Biotechnology Information (NCBI) (Bethesda, MD) BLAST analysis of the accession number of each probe-set was done to identify each gene name. BLAST analysis identified the closest (most similar) known gene existing in the database (the highest known gene at the top of the BLAST list of homologues) which then could be used to search the GeneCards database (Weizmann Institute, Rehovot, Israel). Probe-sets that did not have a known gene were labeled "EST" and their accession numbers were kept as identifiers.
[000160] Human Postmortem Brain Convergence: Information about the candidate genes was obtained using GeneCards, the Online Mendelian Inheritance of Man database at the NCBI database, as well as database searches using PubMed and various combinations of keywords (gene
name, bipolar, depression, psychosis, schizophrenia, alcoholism, suicide, dementia, Alzheimer, opiates, cocaine, marijuana, hallucinogens, amphetamines, benzodiazepines, human, brain, postmortem, lymphocytes, fibroblasts). Postmortem convergence was deemed to occur for a gene (or a biomarker) if there were human postmortem data showing changes in expression of that gene in brains from patients with mood disorders (bipolar disorder, depression), or secondarily of other major neuropsychiatric disorders that impact mood (schizophrenia, anxiety, alcoholism).
[000161 ] Human Genetic Data Convergence: To designate convergence for a particular gene, the gene may have positive reports from candidate gene association studies, or map within lOcM of a microsatellite marker for which at least one study demosntrated evidence for genetic linkage to mood disorders (bipolar disorder or depression) or secondarily to another neuropsychiatric disorder. The University of Southampton's sequence-based integrated map of the human genome (The Genetic Epidemiological Group, Human Genetics Division, was used to obtain cM locations for both genes and markers. The sex-averaged cM value was calculated and used to determine convergence to a particular marker. For markers that were not present in the Southampton database, the Marshfield database (Center for Medical Genetics, Marshfield, WI, USA) was used with the NCBI Map Viewer web-site to evaluate linkage convergence.
[000162] Gene Ontology (GO) analysis: The NetAffx™ Gene Ontology Mining Tool (Affymetrix,
Santa Clara, CA) was employed to categorize the genes in the datasets into functional categories, using the Biological Process ontology branch.
[000163] Ingenuity analysis: Ingenuity Pathway Analysis 5.1 software(Ingenuity Systems, Redwood
City, CA) was used to analyze the direct interactions of the top candidate genes resulting from the CFG analysis, biological roles, as well as employed to identify genes in the datasets that are the target of existing drugs.
[000164] Convergent Functional Genomics (CFG) Analysis Scoring (see FIG. 2A) is presented as folows:
(i) Biomarkers were given the maximum score of 2 points if changed in the human blood samples with high threshold analysis, and only 1 point if changed with low threshold.
(ii) Biomarkers received 1 point for each external cross-validating line of evidence (human postmortem brain data, human genetic data, animal model brain data, and animal model blood data).
(iii) Biomarkers received additional bonus points if changed in human brain and blood, as follows:
(a) 2 points if changed in the same direction;
(b) 1 point if changed in opposite direction;
(iv) Biomarkers also received additional bonus points if changed in brain and blood of the animal model, as follows:
(a) 1 point if changed in the same direction in the brain and blood;
(b) 0.5 points if changed in opposite direction.
[000165] Thus the total maximum CFG score that a candidate biomarker gene can have is 9 (2 + 4 +2
+1). To identify blood biomarkers the scoring pattern described herein is biased more towards awarding additional points for live subject human blood data (if it made the high threshold cut) than literature-derived human postmortem brain data, human genetic data, or the animal model data. The human blood-brain concordance is weighted more favorably than the animal model blood-brain concordance. The scoring analysis presented herein is just one example of assigning quantifiable values to prioritizing biomarkers for mood disorder analysis. Other ways of weighing the scores of line of evidence may give slightly different results in terms of prioritization, if not in terms of the list of genes per se.
[000166] The weightage given to a particular evidence, e.g., post-mortem data or blood expression may be varied. Additional scoring matrices may also be included to account for additional variables. One such example would be the temporal aspect — how long a particular biomarker is turned on.
EXAMPLE 4 Clinical Applications
[000167] A sample, such as, 5-10 ml of blood is obtained from a patient suspected of having a mood disorder. RNA is isolated from the blood using standard protocols, for example with PAXgene blood RNA extraction kit (PreAnalytiX, a QIAGEN/BD company), followed by GLOBINclear™-Human or GLOBINclear™-Mouse/Rat (Ambion/ Applied Biosystems Inc., Austin, TX) to remove the globin mRNA.. Isolated RNA is labeled using any suitable detectable label if necessary for the gene expression analysis.
[000168] The labeled RNA is then quantified for the presence of one or more of the biomarkers disclosed herein. For example, gene expression analysis is performed using a panel of about 10 biomarkers (e.g., BioM 10 panel) by any standard technique, for example microarray analysis or quantitative PCR or an equivalent thereof. The gene expression levels are analyzed and the absent/present state or fold changes (either increased, decreased, or no change) are determined and a score is established
[000169] Applications of biomarkers for mood disorders: There are no reliable clinical laboratory blood tests for mood disorders. Given the complex nature of mood disorders, the current reliance on patient self -report of symptoms and the clinician's impression on interview of patient is a rate limiting step in delivering the best possible care with existing treatment modalities, as well as in developing new and improved treatment approaches, including new medications.
[000170] Biomarkers disclosed herein are used in the form of panels of biomarkers, as exemplified by a BioM-10 Mood panel, for clinical laboratory tests for mood disorders. Such tests can be: 1) at an mRNA level, quantitation of gene expression through polymerase chain reaction, 2) at a protein level, quantitation of protein levels through immunological approaches such as enzyme-linked immunosorbent assays (ELISA).
[000171 ] In conjunction with other clinical information, biomarker testing of blood and other fluids
(CSF, urine) may play a desirable part of personalizing treatment to increase effectiveness and avoid adverse reactions- personalized medicine in psychiatry.
[000172] Biomarker-based tests for mood disorders help: 1) Diagnosis, early intervention and prevention efforts; 2) Prognosis and monitoring response to various treatments; 3) New neuropsychiatric drug development efforts by pharmaceutical companies, at both a pre-clinical and clinical (Phase I, II and III) stages of the process; 4) Identifying vulnerability to mood problems for people in high stress occupations (for example, military, police, homeland security).
[000173] Example 4A: Diagnosis, early intervention and prevention efforts. A patient with no previous history of mood disorders presents to a primary care doctor or internist complaining of non-specific symptoms: low energy, fatigue, general malaise, aches and pains. Such symptoms are reported in conditions such as stress after a job loss, bereavement, mononucleosis, fibromyalgia, and postpartum in the general population, as well as Gulf War syndrome in veterans. A panel of mood biomarkers can substantiate that the patient is showing objective changes in the blood consistent with a low mood/depressive state. This will direct treatment towards, and substantiate the need to use, anti-depressant medications such as Prozac (fluoxetine), Zolof (sertraline), Celexa (citalopram), Cymbalta (duloxetine), Effexor (venlafaxine) or Wellbutrin (buproprion).
[000174] Example 4B : Clinical diagnosis of a young patient. A young patient (child, adolescent, young adult) with no previous history of mood disorders, but coming from a family where one or more blood relatives suffer from depression may be monitored with regular laboratory tests by their primary care doctor/pediatrician using panels of mood biomarkers,. These tests may detect early on a change towards decreased mood (depression) or towards increased mood (mania). This indicates and substantiates the need for initiation of medication treatment with anti-depressants (mentioned above), or mood stabilizers for mania- medication such as Depakote (divalproex), Lithobid (lithium), Lamictal (lamotrigene), Tegretol (carbamazepine), Topomax (topiramate). This early intervention may be helpful to prevent full-blown illness and hospitalizations, with their attendant negative medical and social consequences. The decision to start medications in children and adolescents is particularly difficult without objective proof, due to the potential side-effects of medications in that age group (agitation, suicidality, weigh-gain, sexual side-effects).
[000175] Example 4C: Monitoring mood biomarkers over an extended period. Many patients with bipolar disorder may present initially with a depressive episode to their primary care doctor or psychiatrist. Monitoring mood biomarkers over time may also help to differentiate depression vs. bipolar disorder (manic-depression). This distinction is helpful because the first-line treatments for the two disorders are different: anti-depressants for depression, mood stabilizers for bipolar. If patients are miss-diagnosed as depressives instead of bipolars, and started on anti-depressant medications only, this can lead to activation and flip into manic states. If prior objective substantiation through biomarker testing of mood cyclicity (going up and down) existed, or early
detection of mania in patients put on anti-depressants by seeing a change in biomarker profile towards a high mood state profile before full blown illness and clinical symptoms, an appropriate addition or change to a mood stabilizer medication can be implemented, preventing clinical decompensation, needles suffering and socio-economic loss (employment, relationships).
[000176] Example 4D: Prognosis and monitoring response to various treatments. In depression, initiating medication treatment with current anti-depressants medications is a trial-and -error endeavor. It takes up to 6-8 weeks to see if a medication truly works. By doing a baseline biomarker panel test, and then a repeat test early one in treatment (after 1 week, for example), there would be an early objective indication if an anti-depressant is starting to work or not, and if a switch to another medication is indicated. This would save time and avoid needles suffering for patients, with the attendant socio-economic losses.
[000177] Example 4E: Detecting loss of efficacy of an existing treatment. When a patient has been stable for a while on a medication for depression or bipolar disorder, regular biomarker testing may detect early loss of efficacy of the medication or recurrence of the illness, which would indicate the dose needs to be increased, medication changed, or another medication added, to prevent full blown clinical symptoms.
[000178] Example 4F: Determining adequacy of treatment plan. Objective monitoring with blood biomarker panels of the effect of less reliable or evidence-based interventions: psychotherapy, lifestyle changes, diet and exercise programs for improving mood health. This will show whether the particular intervention works, is sufficient, or medications may need to be added to the regimen.
[000179] Example 4G: Identifying vulnerability to developing mood problems for people in high stress occupations. Military personnel (recruits in boot-camp, active duty soldiers), other people in high-stress jobs (police, homeland security, astronauts), can be monitored on a regular basis to detect early objective changes in mood biomarker profile that would indicate the need for preventive intervention and/or the temporary removal from a high-stress environment.
EXAMPLE 5
New neuropsychiatric drug development
[000180] Early-stage pre-clinical work and clinical trials of new neuropsychiatric medications for treating mood disorders may benefit from biomarker monitoring to help make a decision early on whether the compound is working. This will speed up the drug-development process and avoid unnecessary costs. Depending on the expression profile of the biomarkers, the results of clinical trials may be obtained earlier than usual.
[000181 ] In later-stage large clinical trials, a new compound being tested may show an overall statistically non-significant positive effect, despite working well in a sub-group of people in the study. Biomarker testing may provide an objective signature of the genetic and biological make-up of the responders, which can inform recruitment for subsequent validatory clinical trials with higher
likelihood of success, as well as inform which patients should be getting the medication, once it is
FDA approved and on the market.
