Definitions
- the present invention relates to the use of the apolipoprotein M for the treatment and diagnosis of insulin resistance.
- Body fat is mainly adipose tissue which is one of the largest organs in the body.
- Adipose tissue is a metabolically active organ that, besides having a major role in buffering excess energy, secretes a wide panel of factors with signaling functions in homeostasis and metabolism (4). Some of these factors are polypeptides and proteins synthesized and secreted by the adipocytes, and are thus called adipokines. These molecules act locally in an autocrine- paracrine way or in an endocrine manner. Dysfunctional adipose tissue is a hallmark of systemic insulin resistance and type 2 diabetes. The study of the adipose tissue secretome has led to the identification of hundreds of adipokines with beneficial or detrimental metabolic effects, most of them having been poorly investigated so far (5, 6).
- novel adipokines are still being discovered.
- apoM belongs to the lipocalins family (7).
- S1P sphingosine-l -phosphate
- retinol lipid metabolism and inflammation
- ApoM-deficient mice lack HDL-associated S1P and display increased vascular permeability, which is a component of inflammatory response (10).
- a link between the apoM/SlP axis and energy metabolism has been demonstrated in mice (11) but the role of the apoM itself in insulin resistance has never been investigated neither in humans nor in the adipose tissue.
- the present invention relates to the use of the apolipoprotein M for the treatment and diagnosis of insulin resistance.
- the present invention is defined by the claims.
- the adipose tissue is a secretory organ producing a wide variety of factors that participate in the genesis of metabolic disorders linked to excess fat mass. Weight loss improves obesity related disorders.
- Transcriptomic studies on human AT and a combination of analyses of transcriptome and proteome profiling of conditioned media from adipocytes and stromal cells isolated from human AT has led to the identification of apolipoprotein M (apoM) as a putative adipokine.
- apoM apolipoprotein M
- the inventors aimed to validate apoM as novel adipokine, investigate the relationship of AT APOM expression with metabolic syndrome and insulin sensitivity, and study the regulation of its expression in AT and secretion during calorie restriction induced weight loss.
- APOM expression and secretion were measured during dietary interventions.
- the inventors show that APOM is expressed in human subcutaneous and visceral AT, mainly by adipocytes. ApoM is released into circulation from AT and plasma apoM concentrations correlate with adipose tissue APOM mRNA levels.
- APOM expression in AT is lower in obese compared to lean individuals and reduced in subjects with metabolic syndrome and type 2 diabetes. Regardless of fat depot, there is a positive relationship between AT APOM expression and systemic insulin sensitivity, independently of fat mass and plasma HDL.
- APOM expression is enhanced by insulin sensitizing PPAR agonists and inhibited by TNFa, a cytokine which causes insulin resistance.
- TNFa a cytokine which causes insulin resistance.
- calorie restriction increased AT APOM expression and secretion.
- the inventors show that overexpression of APOM in the AT reduces AT inflammation and improves local insulin sensitivity during high fat diet induced obesity.
- the first object of the present invention relates to a method of treating insulin resistance in a patient in need thereof comprising administering to the patient a therapeutically effective amount of an ApoM polypeptide or a nucleic acid molecule encoding thereof
- insulin resistance has its common meaning in the art. Insulin resistance is a physiological condition where the natural hormone insulin becomes less effective at lowering blood sugars. The resulting increase in blood glucose may raise levels outside the normal range and cause adverse health effects such as metabolic syndrome, dyslipidemia and subsequently type 2 diabetes mellitus. The method of the present invention is thus particularly suitable for the treatment of type 2 diabetes.
- type 2 diabetes or“non insulin dependent diabetes mellitus (NIDDM)” has its general meaning in the art. Type 2 diabetes often occurs when levels of insulin are normal or even elevated and appears to result from the inability of tissues to respond appropriately to insulin. Most of the type 2 diabetics are obese.

- the formulations are easily administered in a variety of dosage forms, such as the type of injectable solutions described above, but drug release capsules and the like can also be employed.
- aqueous solutions For parenteral administration in an aqueous solution, for example, the solution should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose.
- aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration.
- sterile aqueous media which can be employed will be known to those of skill in the art in light of the present disclosure. Some variation in dosage will necessarily occur depending on the condition of the subject being treated. The person responsible for administration will, in any event, determine the appropriate dose for the individual subject.
- a further object of the present invention relates to a method of determining whether a subject has or is at risk of having insulin resistance comprising i) determining the expression level of ApoM in a biological sample obtained from the subject and ii) comparing the expression level determined at step i) with a predetermined reference value wherein detecting differential between the expression level determined at step i) with the predetermined reference value indicated whether the subject has or is at risk of having insulin resistance.
- cardiometabolic disease has its general meaning in the art and relates to cardiovascular diseases associated with metabolic syndrome, such as obesity, diabetes/insulin resistance, hypertension and dyslipidemia.
- cardiovascular diseases refers to cardiac consequences of metabolic syndrome such as atherosclerosis, coronary heart disease, obesity- associated heart disease, insulin resistance- associated heart disease, hypertensive heart disease, cardiac remodeling, heart failure and cardiometabolic diseases disclosed in Hertle et al, 2014; Hua and Nair, 2014; U.S. Pat. Application No. 2012/0214771 and International Patent Application No. 2008/094939.
- risk in the context of the present invention, relates to the probability that an event will occur over a specific time period and can mean a subject's "absolute” risk or “relative” risk.
- Absolute risk can be measured with reference to either actual observation post-measurement for the relevant time cohort, or with reference to index values developed from statistically valid historical cohorts that have been followed for the relevant time period.
- Relative risk refers to the ratio of absolute risks of a subject compared either to the absolute risks of low risk cohorts or an average population risk, which can vary by how clinical risk factors are assessed.
- Odds ratios the proportion of positive events to negative events for a given test result, are also commonly used (odds are according to the formula p/(l-p) where p is the probability of event and (1- p) is the probability of no event) to no- conversion.
- "Risk evaluation,” or “evaluation of risk” in the context of the present invention encompasses making a prediction of the probability, odds, or likelihood that an event or disease state may occur, the rate of occurrence of the event or conversion from one disease state to another. Risk evaluation can also comprise prediction of future clinical parameters, traditional laboratory risk factor values, or other indices of relapse, either in absolute or relative terms in reference to a previously measured population.
- the methods of the present invention may be used to make continuous or categorical measurements of the risk of conversion, thus diagnosing and defining the risk spectrum of a category of subjects defined as being at risk of conversion.
- the invention can be used to discriminate between normal and other subject cohorts at higher risk.
- the present invention may be used so as to discriminate those at risk from normal.
- the biological sample is a blood sample.
- blood sample means any blood sample derived from the subject. Collections of blood samples can be performed by methods well known to those skilled in the art.
- the blood sample is a serum sample or a plasma sample.
- the measurement of the level of ApoM in the blood sample is typically carried out using standard protocols known in the art.
- the method may comprise contacting the blood sample with a binding partner capable of selectively interacting with ApoM in the sample.
- the binding partners are antibodies, such as, for example, monoclonal antibodies or even aptamers.
- the binding may be detected through use of a competitive immunoassay, a non-competitive assay system using techniques such as western blots, a radioimmunoassay, an ELISA (enzyme linked immunosorbent assay), a“sandwich” immunoassay, an immunoprecipitation assay, a precipitin reaction, a gel diffusion precipitin reaction, an immunodiffusion assay, an agglutination assay, a complement fixation assay, an immunoradiometric assay, a fluorescent immunoassay, a protein A immunoassay, an immunoprecipitation assay, an immunohistochemical assay, a competition or sandwich ELISA, a radioimmunoassay, a Western blot assay, an immunohistological assay, an immunocytochemical assay, a dot blot assay, a fluorescence polarization assay, a scintillation proximity assay, a homogeneous time resolved fluorescence
- the aforementioned assays generally involve the binding of the partner (ie. antibody or aptamer) to a solid support.
- Solid supports which can be used in the practice of the invention include substrates such as nitrocellulose (e.g., in membrane or microtiter well form); polyvinylchloride (e.g., sheets or microtiter wells); polystyrene latex (e.g., beads or microtiter plates); polyvinylidine fluoride; diazotized paper; nylon membranes; activated beads, magnetically responsive beads, and the like.
- An exemplary biochemical test for identifying specific proteins employs a standardized test format, such as ELISA test, although the information provided herein may apply to the development of other biochemical or diagnostic tests and is not limited to the development of an ELISA test (see, e.g., Molecular Immunology: A Textbook, edited by Atassi et al. Marcel Dekker Inc., New York and Basel 1984, for a description of ELISA tests). Therefore ELISA method can be used, wherein the wells of a microtiter plate are coated with a set of antibodies which recognize ApoM. A sample containing or suspected of containing ApoM is then added to the coated wells.
- the plate(s) can be washed to remove unbound moieties and a detectably labelled secondary binding molecule added.
- the secondary binding molecule is allowed to react with any captured sample marker protein, the plate washed and the presence of the secondary binding molecule detected using methods well known in the art.
- Measuring the level of ApoM may also include separation of the compounds: centrifugation based on the compound’s molecular weight; electrophoresis based on mass and charge; HPLC based on hydrophobicity; size exclusion chromatography based on size; and solid-phase affinity based on the compound's affinity for the particular solid-phase that is used.
- said one or two biomarkers proteins may be identified based on the known "separation profile" e.g., retention time, for that compound and measured using standard techniques.
- the separated compounds may be detected and measured by, for example, a mass spectrometer.
- levels of immunoreactive ApoM in a sample may be measured by an immunometric assay on the basis of a double-antibody "sandwich” technique, with a monoclonal antibody specific for ApoM.
- said means for measuring ApoM level are for example i) a ApoM buffer, ii) a monoclonal antibody that interacts specifically with ApoM, iii) an enzyme- conjugated antibody specific for ApoM and a predetermined reference value of ApoM.
- the predetermined reference value is a threshold value or a cut off value.
- a “threshold value” or “cut-off value” can be determined experimentally, empirically, or theoretically.
- a threshold value can also be arbitrarily selected based upon the existing experimental and/or clinical conditions, as would be recognized by a person of ordinary skilled in the art. For example, retrospective measurement of expression level of the gene in properly banked historical patient samples may be used in establishing the predetermined reference value. The threshold value has to be determined in order to obtain the optimal sensitivity and specificity according to the function of the test and the benefit/risk balance (clinical consequences of false positive and false negative).
- the optimal sensitivity and specificity can be determined using a Receiver Operating Characteristic (ROC) curve based on experimental data.
- ROC Receiver Operating Characteristic
- the full name of ROC curve is receiver operator characteristic curve, which is also known as receiver operation characteristic curve. It is mainly used for clinical biochemical diagnostic tests.
- ROC curve is a comprehensive indicator that reflects the continuous variables of true positive rate (sensitivity) and false positive rate (1 -specificity). It reveals the relationship between sensitivity and specificity with the image composition method.
- a series of different cut-off values are set as continuous variables to calculate a series of sensitivity and specificity values. Then sensitivity is used as the vertical coordinate and specificity is used as the horizontal coordinate to draw a curve. The higher the area under the curve (AUC), the higher the accuracy of diagnosis.
- AUC area under the curve
- the point closest to the far upper left of the coordinate diagram is a critical point having both high sensitivity and high specificity values.
- the AUC value of the ROC curve is between 1.0 and 0.5. When AUC>0.5, the diagnostic result gets better and better as AUC approaches 1. When AUC is between 0.5 and 0.7, the accuracy is low. When AUC is between 0.7 and 0.9, the accuracy is moderate.
- the predetermined reference value is the expression level of ApoM determined in a population of healthy individuals. Typically, it is concluded that the subject has or is at risk of having insulin resistance when the expression level of is at least 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 100 fold lower than the expression level determined in a population of healthy individuals.

Proteins were extracted from tissue lysates and quantified according to Bradford. Fifteen pg proteins were separated by SDS-PAGE and after transfer to nitrocellulose membranes were immunoblotted using antibodies raised against Ser(P)-Akt 473 or total- Akt.
- EXAMPLE 1 apolipoprotein M: a novel adipokine decreasing with obesity and upregulated by calorie restriction.
- Cohort A included 8 obese women (BMI 33.9 ⁇ 0.1 kg/m 2 ) with stable weight during the 3 months preceding the study. As previously described in (12), exclusion criteria were hypertension, diabetes, hyperlipidemia, or any drug treatment.
- Cohort B comprised 56 women scheduled to have abdominal surgery (laparoscopic or laparotomic cholecystectomy, hysterectomy and gastric banding) at the Departments of Surgery and Gynecology at Kralovske Vinohrady Faculty Hospital in Prague.
- BMI ranged from 17.3 to
- Cohort C included 14 obese (BMI 34.1 ⁇ 4.7 kg/m2) women with or without polycystic ovary syndrome (PCOS) recruited during 2004-2005.
- Anthropometric measurements, blood sampling, euglycemic-hyperinsulinemic clamp and subcutaneous abdominal adipose tissue needle biopsies were performed as described in (14).
- Cohort D included 10 metabolically healthy overweight and obese women (BMI 34.1 ⁇
- Cohort E included a subgroup of 336 (111 men and 225 women) overweight and obese individuals (BMI 34.1 ⁇ 4.7 kg/m2) from the DiOGenes Study in 8 European countries (16). Individuals followed a VLCD for 8 weeks, and those that lost at least 8% of their baseline weight were randomized to one of five ad libitum follow-up diets for 6 months. Clinical measures and subcutaneous abdominal adipose tissue biopsies were taken at each time-points. The participants were instructed not to change their habitual activity during the study. Only baseline and post-VLCD fat samples and clinical data were investigated in the present study.
- the risk score for metabolic syndrome was calculated according to (19).
- the quantitative insulin-sensitivity check index (QUICKI), calculated as l/[log(I) + log(G)], where I is fasting insulin (pun its/m L) and G is fasting glucose (mg/dL), was used since it has been reported to be more reproducible and has a better correlation to the reference glucose clamp method than other surrogates including HOMA-IR, especially for longitudinal studies (20).
- NanoLC/ESI LTQ-Orbitrap MS/MS was used for analysis of 24h culture media of the different human adipose tissue cell types. Details are reported in (23).
- microarray assays were performed using the Agilent Whole Human Genome Microarray 4x44K v2 according to manufacturer’s recommendations (Agilent Technologies) and analysed as described in (21).
- Subcutaneous adipose tissue catheterization To measure arteriovenous differences across subcutaneous abdominal adipose tissue, venous and arterial blood were sampled in 8 obese women (BMI 33.9 ⁇ 0.1 kg/m 2 ) as described in (12) (cohort A).
- the Human multipotent adipose-derived stem cell (hMADS) cells were cultured and differentiated as previously described (24). Briefly, after six days of proliferation, the cells were incubated in the differentiation medium (serum- free DMEM low glucose/ Ham’s F-12 medium containing l0pg/ml of transferrin, 5pg/ml of insulin, 0.2 nM triiodothyronine, 100mM 3- isobutyl-l-methylxanthine, 1 mM dexamethasone, and 100 nM rosiglitazone). Three days after (day3), dexamethasone and 3 -isobutyl- l-methylxanthine were omitted from the medium.
- the differentiation medium serum- free DMEM low glucose/ Ham’s F-12 medium containing l0pg/ml of transferrin, 5pg/ml of insulin, 0.2 nM triiodothyronine, 100mM
- Rosiglitazone was omitted at day 9. By day 13, cells were fully differentiated into adipocytes. At day 14, cells were treated with 100 nM of the PPARy agonist rosiglitazone (Alexis Biochemicals), or 300 nM of the PPARa agonist GW7647 (Sigma), or 10 ng/ml TNFa (Sigma), or the vehicle, for 4 days.
- PPARy agonist rosiglitazone Alexis Biochemicals
- 300 nM of the PPARa agonist GW7647 Sigma
- 10 ng/ml TNFa 10 ng/ml TNFa
- Adipose tissue samples of about 400 mg obtained from 10 obese women were cut into small pieces and incubated at 37°C for 4h in 4ml of Krebs/Ringer phosphate buffer supplemented with lg/F glucose and 20g/F bovine serum albumin as described in (15) (cohort D).
- Real-time PCR was performed in duplicate using a set of TaqMan (Thermo Fisher Scientific) probes and primers assays (Hs002l9533_ml). 20 ng cDNA was analyzed on a StepOne Plus Real-Time PCR system (Applied Biosystems, Carlsbad, CA) or, for longitudinal dietary interventions, using the Bio markTM HD system (BioMark) as described in (21). Adipose tissue and cell data were normalized to GUSB (Hs00939627_ml) or LRP10 (Hs0l047362_ml), respectively.
- GUSB Hs00939627_ml
- LRP10 Hs0l047362_ml
- ApoM protein level was measured in duplicate using a human apoM EFISA kit (E-EF- H0473, Elabscience, Clinisciences, Nanterre, France), following manufacturer’s instructions. ApoM concentration was calculated using sigmoidal standard curve fitted by nonlinear regression analysis for each test.
- Gaussian distribution was tested using the D'Agostino & Pearson test. For comparing data from two groups, where a normal distribution was unattainable, a Wilcoxon or Mann- Whitney test was employed for paired or unpaired comparisons respectively. For a comparison using data from more than two groups, ANOVA was performed with Dunnett’s post-hoc test or Kruskal- Wallis with Dunn’s post-hoc test for non-normal data distribution. Linear regression was performed with adipose tissue APOM expression as the dependent variable and the Benjamini-Hochberg procedure was applied to account for multiple testing. Multiple regression was performed with all variables significantly correlated with adipose tissue APOM expression. Partial correlations were computed to assess direct correlations independently of other confounding variables.
- APOM is released by human adipose tissue and secreted by adipocytes.
- the adipose tissue contains different cell types including preadipocytes and immune, endothelial and progenitor cells corresponding to the stroma vascular fraction.
- preadipocytes and immune, endothelial and progenitor cells corresponding to the stroma vascular fraction.
- a comparative proteomic analysis of the proteins secreted by these 5 distinct human adipose tissue cell populations led to the identification of 626 proteins secreted by adipocytes, 123 of which have never been described in the literature as produced by the adipose tissue and were found specifically in the media of mature adipocytes.
- We compared this list of potentially new adipokines with the data of the transcriptome analyses on the same different adipose tissue cellular fractions.
- APOM expression and secretion were compared between isolated adipocytes and stroma vascular fractions. Compared to the stroma vascular fraction of adipose tissue, APOM was expressed ( Figure IB) and secreted ( Figure 1C) mainly by adipocytes.
- cohort B there was a positive relationship between plasma apoM and subcutaneous adipose tissue APOM expression (cohort B, data not shown).
- APOM expression increased in a time-dependent manner (data not shown). This cell line was used to investigate the effect of prominent regulators of adipocyte secretory activities (25).
- APOM mRNA level was reduced by TNFa treatment with ( Figure ID) and enhanced by a treatment with PPAR agonists (PPARy, rosiglitazone; PPARa, GW 7647)
- APOM expression was analysed in paired samples of subcutaneous and visceral adipose tissue from lean and obese women (cohort B). Irrespective of the fat depot, a higher APOM expression was found in lean compared to obese individuals ( Figure 2B). As previously reported (26), plasma apoM was lower in overweight and obese compared to lean women (data not shown). Moreover, a strong negative correlation between body fat and APOM expression in both subcutaneous and visceral adipose tissue was found (cohort B, Figure 2C).
- Low adipose tissue APOM expression is associated with a dysmetabolic phenotype.
- Obesity is an important risk factor for metabolic syndrome as the enlargement of fat mass impacts adipocyte biology. Adipocyte size is linked to metabolic syndrome (27).
- Figure 3A shows that subcutaneous adipose tissue characterized by large fat cells (hypertrophy) displayed lower APOM expression than fat from subjects matched for BMI but with many small adipocytes (hyperplasia), irrespective of body weight status (cohort F). A negative correlation between adipose tissue APOM expression and adipocyte volume was found accordingly (data not shown).
- Subcutaneous adipose tissue APOM expression was lower in subjects with type 2 diabetes and prediabetes (impaired fasting glucose and/or impaired glucose tolerance, assessed as in (28)) compared to normal glucose-tolerant individuals (cohort E, Figure 4A).
- apoM expression and plasma levels are associated with obesity and comorbidities developed in obesity, we aimed to study if a weight-reducing diet which improves metabolic profile could influence the levels of apoM expression and production.
- VLCD The secretion of apoM by subcutaneous adipose tissue explants was assessed in obese women during a 1 -month VLCD (cohort D).
- the VLCD induced weight and body fat loss and an improvement in insulin sensitivity.
- ApoM concentration in media from adipose tissue explants significantly increased (+22%) at the end of the VLCD ( Figure 5B).
- a combination of microarray studies and proteomic profiling of conditioned media from freshly isolated adipocytes and cell populations in the stroma vascular fraction from human adipose tissue has led to the identification of apoM as a novel adipokine.
- the present study shows that the human adipose tissue is a site of expression of the APOM gene and that adipose tissue and predominantly adipocytes do secrete apoM.
- apoM With reference to other apolipoproteins, the apoM, which was identified in 1999 (33), is comparatively recent. The apoM has been mainly studied in liver where it is produced in hepatocytes; also, kidney proximal tubule cells express apoM (7). Here, we show that apoM is released from adipose tissue in vivo and ex vivo, particularly from adipocytes. The apoM concentration in media from adipose tissue explants in culture is comparable to other adipokines, such as leptin or IL6 (15).
- adipokines such as leptin or IL6
- Weight gain in adults is accompanied by an increase in adipocyte size.
- Adipocytes of obese subjects are dysfunctional, especially regarding metabolism and secretory functions (34).
- Large adipocytes were reported to be associated with metabolic disease, insulin resistance and type 2 diabetes in multiple studies (35).
- APOM mRNA level was reported to be associated with metabolic disease, insulin resistance and type 2 diabetes in multiple studies (35).
- APOM mRNA level was associated with metabolic disease, insulin resistance and type 2 diabetes in multiple studies (35).
- hypertrophic adipose tissue containing few but large adipocytes, displayed lower APOM expression compared to hyperplastic tissue that includes more adipocytes but with smaller size.
- the APOM gene expression thus seems to be a hallmark of healthy adipose tissue.
- Unhealthy adipose tissue deficient in beneficial adipokines such as adiponectin and producing excess of harmful factors, is one of the features of metabolic syndrome and diseases such as insulin resistance and type 2 diabetes.
- the present study has shown that, in contrast to most adipokines (5, 21) and similarly to adiponectin (37), APOM gene expression in adipose tissue was lower with increasing adiposity. This trend is in accordance with the plasma concentration of apoM lower in obese compared to lean individuals, as previously reported (26).
- APOM mRNA level is lower in adipose tissue obtained from subjects with metabolic syndrome, independently of fat mass, and that adipose tissue APOM mRNA level is associated with several metabolic syndrome features (waist circumference, plasma HDF and triglycerides).
- plasma apoM has been described as a component of the pre-b HDL (8) and reduced with metabolic syndrome (38), in accordance with the present report.
- adipose tissue APOM mRNA level is reduced with prediabetes and diabetes. More evidence is provided by another independent longitudinal study where lean men were investigated before and after a 4-d treatment with the glucocorticoid analogue, dexamethasone. The treatment induced insulin resistance without change in fat mass (42).
- the adipose tissue microarray data included APOM and showed that glucocorticoid exposure downregulated (mean fold change 0.6) APOM gene expression in subcutaneous fat
- apoM was reported as a carrier of several anti-inflammatory lipids (7).
- apoM/SlP protects against atherosclerosis (9) and controls the metabolic activity of brown fat (11).
- the ability of apoM to bind anti-inflammatory factors could convey a local effect on the inflammatory status of the adipose tissue. Though, this highlights apoM as a good candidate for monitoring healthy adipose tissue status.
- the present study reports apoM production by adipocytes for the first time. It shows that APOM mRNA level is reduced in adipose tissue from obese subjects and independently of body fat mass, is also lower in individuals with insulin resistance, type 2 diabetes or dyslipidemia. Patterns of expression and secretion in adipose tissue indicate that apoM is also regulated in response to calorie-restriction induced weight loss.
- apoM is a new adipokine, which may reflect changes in adipose tissue mass and whole body metabolic dysfunction, and which presence in the white adipose tissue is positively associated with insulin sensitivity.
- EXAMPLE 2 Effect of human APOM overexpression in the perigonadic adipose tissue in high fat fed mice.
- mice fed ad libitum were randomized in 3 groups of 10 mice according to body weight and glucose tolerance tests (lmg glucose/g body weight, intraperitoneal). Mice were housed at room temperature and manipulated according to Inserm guidelines and European Directive 2010/63/UE in the local animal care facility (agreements A 31 555 04 and C 31 555 07). Mice were fed with a 60% high fat diet for 4 weeks.
- mice were anaesthetized and perigonadic adipose tissues (PG-AT) were injected with recombinant adenoviruses (2xl0 9 particles/fat pad) containing coding sequences of human APOM (ad-hAPOM) or green fluorescent protein (ad-GFP), or with saline (sham) or red fluorescent protein (mCherry).

- II- 1 b interleukin 1
- Mcpl macrophage chemoattractant protein
- Tnf-a tumor necrosis factor

Abstract
Dans le cadre de la présente invention, des inventeurs ont examiné le taux et la sécrétion d'ARNm de l'apoM dans l'AT de patients lors de 6 essais cliniques indépendants et in vitro dans des adipocytes hMADS. L'expression et la sécrétion d'apoM ont été mesurées pendant des interventions alimentaires. Les inventeurs ont montré que l'apoM est exprimée dans l'AT sous-cutané et viscéral humain et est libérée dans la circulation à partir de l'AT. L'expression de l'apoM dans l'AT est inférieure chez les personnes obèses par comparaison avec des individus maigres et réduite chez des sujets atteints de syndrome métabolique et de diabète de type 2. Quel que soit le dépôt de graisse, il existe une relation positive entre l'expression d'apoM de l'AT et la sensibilité systémique à l'insuline. Enfin, les inventeurs ont montré que la surexpression d'apoM dans l'AT réduit l'inflammation d'AT et améliore la sensibilité locale à l'insuline dans le cas d'une obésité induite par un régime riche en graisses. Ainsi, la présente invention concerne l'utilisation de l'apolipoprotéine M pour le traitement et le diagnostic de la résistance à l'insuline.
