Description

The new gene relevant to glutaminyl cyclase
Invention field
The present invention relates to as glutaminyl cyclase (QC; new glutamine peptide cyclotransferase sample albumen (QPCTL) of isozyme EC2.3.2.5); and relate to the isolating nucleic acid of these isozymes of coding; described isolating nucleic acid all can be used for finding new therapeutant, for measuring cyclase activity and for the inhibit activities of deterministic compound to these glutaminyl cyclase isozymes.
Background of invention
Glutaminyl cyclase (QC, EC2.3.2.5) catalyze ammonia cardinal extremity glutamine residue is to Pyrrolidonecarboxylic acid (pGlu *) intramolecular cyclization, thus release ammonia.QC was separated (Messer, M.1963Nature4874,1299) by Messer first the emulsion from tropical plants papaya (Caricapapaya) in 1963.After 24 years, corresponding enzymic activity finds in animal hypophysis (1987JBiolChem262, the 8532-8536 such as Busby, W.H.J.; Fischer, W.H. and Spiess, J.1987ProcNatlAcadSciUSA84,3628-3632).For Mammals QC, can confirm that QC causes Gln to be converted into pGlu (1987JBiolChem262, the 8532-8536 such as Busby, W.H.J. at the precursor of TRH and GnRH; Fischer, W.H. and Spiess, J.1987ProcNatlAcadSciUSA84,3628-3632).In addition, initial QC positioning experiment shows it and locates altogether with the presumption product of its katalysis in Niu Chuiti, this promotes further its potential function in peptide hormone synthesis 1995JNeuroendocrinol7,445-453 such as () Bockers, T.M..On the contrary, the physiological function of plant QC is more unclear.With regard to the enzyme from papaya (C.papaya), effect 2001CellMolLifeSci58,556-570 such as () ElMoussaoui, A. in the plant defense of opposing pathogenic microbes is proposed.The presumption QC (2000ProteinExprPurif20, the 27-36 such as Dahl, S.W.) from other plant is identified more recently by gene comparision.But the physiological function of these enzymes is still unclear.
From the known QC display of plant and animal, the stringent specificity of L-glutaminate in substrate N-terminus position is found that their dynamics observes Michaelis-Menten equation (Pohl, T. 1991ProcNatlAcadSciUSA88,10059-10063 is waited; The 1988AnalBiochem175 such as Consalvo, A.P., 131-138; 1996BiolChemHoppeSeyler377, the 395-398 such as Gololobov, M.Y.).But, compare primary structure from the QC of papaya and the primary structure from mammiferous well-conserved QC and then do not disclose any sequence homology 2000ProteinExprPurif20,27-36 such as () Dahl, S.W..Although plant QC seems to belong to a new family (Dahl, S.W. 2000ProteinExprPurif20 is waited, 27-36), but find that Mammals QC has the remarkable sequence homology (Bateman with bacterium aminopeptidase, R.C. 2001Biochemistry40 is waited, 11246-11250), thus draw conclusion like this, the QC namely from plant and animal has Different Evolutionary origin.
Recently, recombinant human QC has been confirmed and from the QC-active catalytic aminoterminal glutamyl of brain extract and L-glutamic acid cyclisation.The most surprisingly find near pH6.0, be conducive to the enzymatic Glu of cyclisation 1-transform, and Gln 1conversion to pGlu derivative occurs optimal pH about 8.0 time.Due to can by suppress recombinant human QC active and from the QC of porcine pituitary extract activity and suppress pGlu-A beta related peptides to be formed, therefore QC enzyme develops the target being used for the treatment of the medicine of alzheimer's disease.

Definition
Enzyme inhibitors
Reversibility enzyme inhibitors: comprise competitive inhibitor, reversible non-competitive inhibition agent slow fixation or close adhesion inhibitor, transition state analog and multiple substrate analogue.
competitive inhibitordisplay
I) interact with enzyme non-covalent,
Ii) with substrate competition zymophore,
The Main Function mechanism of reversibility enzyme inhibitors and the definition of dissociation constant can be shown as follows:
The formation of enzyme-inhibitor [E-I] mixture stops Binding Capacity, and thus this reaction can not be advanced into normal physiological product P.Larger inhibitor concentration [I] produces comparatively large [E-I], thus make can be less with the resolvase of Binding Capacity.
reversible non-competitive inhibition agent
I) (allosteric combining site) is combined at other position except reactive site
Ii) the enzyme conformational change reducing or stop catalytic activity is caused
slow fixation or close adhesion inhibitor
I) be the competitive inhibitor that the balance wherein between inhibitor and enzyme slowly reaches,
Ii) (k onslowly), may owing to the conformational change that must occur in enzyme or inhibitor
A) transition state analog often
B) with enzyme concn (sub-nmole K dvalue) in similar concentration effectively
C) because of k offbe worth so low, therefore the inhibitor of these types " almost " is irreversible.
transition state analog
It is the competitive inhibitor of the transition state of mimetic enzyme catalysis reaction.Enzyme catalysis occurs because reducing the energy of this transition state, and therefore, transition state keying action has precedence over Binding Capacity effect.
multiple substrate analogue
For the reaction relating to two or more substrates, can design such competitive inhibitor or transition state analog, it contains the constitutional features similar to two or more substrates described.
Irreversible enzyme inhibitor: always drive the balance between unconjugated enzyme and inhibitor and enzyme inhibitor complex (E+I<--->E-I) to the right, containing making the irreversible covalent linkage of restraining effect (about 100kcal/ mole).
affinity tag
. for the irreversible inhibitor of reactive site(competitive irreversible inhibitor), by enzyme identification (reversibility, specific binding), forms covalent linkage subsequently, and
I) structurally similar to substrate, transition state or product, thus create conditions for specificity between medicine and target enzyme interacts,
Ii) reactive functional groups (such as the nucleophilic group ,-COCH that create conditions is formed containing promising covalent linkage 2br).
Following reaction scheme describes reagent for reactive site and its target enzyme, wherein K dbe dissociation constant and k deactivation(k inactivation) be covalent linkage synthesis speed.
. based on the enzyme-deactivating thing (being also called suicide inhibitor) of mechanismbe the reagent (non-reacted) for reactive site, this reagent and wherein this reagent change into activity form (activation) zymophore because of enzyme catalysis ability is combined.Once activate, then form covalent linkage between enzyme therewith at described inhibitor.
Following reaction scheme shows the mechanism of action based on the enzyme-deactivating thing of mechanism, wherein K dthe mixture that dissociates, k 2be with enzyme in conjunction with time activation inhibitor speed, k 3be the inhibitor P the activated speed (product still can responding property) of dissociating from this enzyme and k 4the speed forming covalent linkage between inhibitor and enzyme activated.
(covalent linkage is formed, k in deactivation 4) must at (the k that dissociates 3) occur before, otherwise activity inhibitor is released in environment now.For side reaction more than effective inactivation system and undesirable Minimum Residual, partition rate k 3/ k 4, namely releasing product is to deactivation product ratio, should minimize.Large partition rate (support is dissociated) causes nonspecific reaction.
Noncompetitive enzyme inhibitors: following equation can be write out from the definition of noncompetitive inhibitor (inhibitor be only combined with ES mixture):
Described ES mixture to dissociate described substrate with the dissociation constant equaling Ks, this substrate (namely having null Ks value) and ESI mixture does not dissociate.The K of expection Michaelis-Menten type enzyme mreduce.Increasing concentration of substrate causes ESI (can not develop into the mixture of reaction product) concentration to increase, therefore can not derepression effect.

Guillain-Barr é syndrome (GBS)
Alternative names is Landry-Guillain-Barr é syndrome, acute idiopathic polyneuritis, infectious polyneuritis or acute inflammation polyneuropathy.
Guillain-Barr é syndrome is a kind of serious conditions occurred when neural part is attacked in body defenses (immunity) system mistake.This causes and causes amyasthenic neuroinflamation, and wherein the latter continues to worsen.
Guillain-Barr é syndrome is autoimmune disorder.The syndromic clear and definite cause of disease of unknown Guillain-Barr é.This syndrome can occur at any age, but 30 and two kinds of sexes of 50 years old crowd in the most common.It is secondary mild infection usually, and normally respiratory tract (lung) infects or digestive tube (gi tract are long) infection.Usually, the initial sign that infects disappears before the symptom of Guillain-Barr é starts.Guillain-Barr é syndrome causes the inflammation of injured nerve part.This nervous lesion causes tingle, myasthenia and paralysis.The tectum (myelin) that this inflammation affects the nerves usually.This infringement is called demyelination.Demyelination slows down Neurotransmission effect.Nerve can be caused to quit work to the infringement of neural other parts.
The symptom of Guillain-Barr é worsens extremely rapidly.Namely it only can reach the most serious symptom in several hours.Myasthenia or muscle function are lost (paralysis) and are affected health both sides.If myasthenia starts at leg and extends to arm subsequently, then this myasthenia is called ascending paralysis.
Patient can aware tingle, podalgia or hand pain and clumsiness.When muscle function forfeiture increases the weight of, this patient may need assisted respiartion.

Chronic inflammatory demyelinating polyneuropathy (CIDP)
A kind of similar to GBS but be that the disease of feature is called chronic inflammatory demyelinating polyneuropathy (CIDP) with chronic process.For CIDP, the also general definition be suitable for, but observe that it is contrary with GBS, its progressive stage, is continued above 4 weeks, often beyond 6 months, and often leaves defect in patients.Because GBS and CIDP causes serious paretic mechanism to comprise to be secondary to the immune response of T mediated by lymphocytes and the inflammation of peripheral nerve unit demyelinization.This hypothesis by the amount of the complement complex observed in patients serum and cerebrospinal fluid or cytokine raise support.At present by demyelination process, the demyelination process especially in nerve root region is considered as the developing decisive mechanism of nerve block.Based on a kind of theoretical step relatively important in early days in development using blood/cerebrospinal fluid (CSF) barrier as this disease.Another kind of theory claims that the leakage at blood/CSF barrier develops because of this disease and causes protein content increase in CSF.In a word, not being directly involved in immune nonspecific sera component can infiltrate CSF from blood, causes neurone or spongiocyte functional disorder and/or regulates neuronal activity.Another kind of mechanism is that CSF flow velocity reduces, and the protein content in this possible explanation CSF increases.This explanation does not require that blood/CSF barrier selectivity is impaired or change.Although mentioned whole effects may be important for GBS and CIDP process, but they are not still illustrated the actual contribution of symptom.Also can not set up contacting between the protein concn increased in CSF and certain electric physiological Study result or clinical picture.Be described in recently in the CSF of GBS patient and patients with multiple sclerosis with the interactional factor in action potential dependency sodium channel (W ü z etc. 1995, MuscleandNerve18,772-781).The factor described in Brinkmeier (Brinkmeier etc. 1996, MuscleandNerve19,54-62) report has and is less than 3kDa molecular weight, and is less than 1kDa under stricter experiment condition.Even if observe and the fact of described factor active also not obvious reduction after CSF and protease incubation based on this, author reaches a conclusion; The described factor is non-antibody also non-cytokine both.
Multiple sclerosis (MS)
Multiple sclerosis is the autoimmune disorder affecting central nervous system (brain and spinal cord).The impact of multiple sclerosis on women exceedes the male sex usually.This illness is the most common to start between 20 years old-40 years old, but can show effect on any age.The definite cause of disease is unknown, but it is believed that MS is caused by the protectiveness material-myelin infringement because surrounding neurocyte.This disease is PD, means that this infringement increases the weight of in time.Inflammation destroys myelin, leaves multiple scar tissue district (sclerosis).When the immune cells attack neural system of health self, inflammation occurs.This inflammation causes the slack-off or retardance of nerve impulse, produces MS symptom.The recurrent exerbation of inflammation or burst can occur along region any in brain and spinal cord.Symptom is changeable, because the position of each invasion and attack is different with degree.Usually, last for days, several weeks or several months outbreak and symptom occurrence number declines or asymptomatic (alleviation) alternately occurs.(recurrence) is common repeatedly, but also can occur without the continuing advances alleviating period.
Which kind of material not clear starts is attacked.MS patient generally has higher immuning cell number than Healthy People, and this prompting immunne response may play a role.Modal theory relates to virus or hereditary defect or its and combines.This disease seems also there is genetic linkage.Compared with other area, MS more may appear at the north, Europe, northern US, South Australia and New Zealand.Geography research shows there is relevant environmental factor.There is the people of MS family history and MS sickness rate those people that live in district higher, there is this higher sick risk.
Knownly at present multiple sclerosis cannot be cured.But, there are numerous therapies of this disease that can slow down.Therapeutic purpose control symptom and maintain orthobiosis quality.

Be used in NCBI ( http:// www.ncbi.nlm.nih.gov/BLAST/) on Nucleotide BLAST, utilize people QC as template, find polynucleotide of the present invention by similarity searching.This search causes the presumption QPCTL finding to be positioned on karyomit(e) 19, and its coding region is in 19q13.32 region.Based on this search, devise the primer (table 4) for using cell line selection people isoQC.The separation cDNA of people QPCTL contains the open reading-frame (ORF) of the protein of coding 382 amino acid lengths, and wherein said open reading-frame (ORF) is relevant to people QC, the sequence thereto of performance 45.24% and 71.98% similarity.The different bioinformatics of applied forcasting Subcellular Localization ( www.expasy.ch) do not produce reliable results.According to described predictor, prediction is diverted golgi body or plastosome.
In the M28 family member of people QPCTL and metallopeptidase ClanMH, the amino acid alignment result of other member shows people QPCTL albumen and has and the overall sequence homology of people and mouse QC (Fig. 1) and bacterium aminopeptidase (Fig. 3) and structural homology.The database search of extra people QPCTL genes involved is disclosed and there is rodent, monkey, ox and dog QPCTL.The comparison result of these sequences and described novel people QPCTL shows them and shows the huge homology with its mankind's counterpart.The zinc complexing residue of people QC (Asp-Glu-His) guards (Fig. 2) in from the QPCTL of Different Origin.
People isoQC gene contains at least 8 exons.The sequence of encoding human isoQC protein is positioned at the 1st to the 7th exon.People isoQC is positioned No. 19 chromosome position 19q13.32 place.Cell line selection method for people isoQC discloses from liver (Hep-G2, hepatocellular carcinoma), skin (HaCaT, keratinocyte) and neuronal tissue (LN405, astrocytoma; SH-SY5Y, neuroblastoma) cell source (Fig. 6) in transcript.
The functional expression of the QPCTL-cDNA of separation is tested in several expressive host.The pichia pastoris phaff (P.pastoris) being successfully applied to people QC expresses the protein not having generation to have enzymic activity.Expression in mammalian cell causes activity being detected, but expression level is extremely low.Therefore, the protein of enzymic activity can not be separated with the knowledge of technician.Only use in the intestinal bacteria (E.coli) unconventional expression condition (existence 37 DEG C in 1% glucose express 4 hours, use 20 μMs of IPTG abduction deliverings) express GST-QPCTL fusion rotein after be just separated to the protein of enzymic activity.Described expression condition produces low expression level in intestinal bacteria, and it is required that this is that described peptide chain generating function folds.
In another embodiment, the present invention relates to QPCTL knock-out animal.Described animal is preferably rat or mouse.Knock-out mice is a kind of important tool analysing in depth the use in QPCTL gene function.
Polynucleotide of the present invention can be rna form or DNA form; DNA should be understood to comprise cDNA, genomic dna and synthetic DNA.Described DNA can be double-strand or strand, and if in strand, then this DNA can be coding strand or non-coding (antisense) chain.The encoding sequence of encoding mature polypeptide can be identical with the encoding sequence shown in SEQIDNO:2-9, or it can be different from the encoding sequence of coding same mature polypeptide because of the redundancy of genetic codon or degeneracy or single nucleotide polymorphism.Such as, described encoding sequence also can be the rna transcription thing comprising the arbitrary complete length of SEQIDNO:11-18.
The polynucleotide of the maturation protein of coding SEQIDNO:2-9 can include, but are not limited to the encoding sequence of described maturation protein itself; The encoding sequence of the additional additional coding sequence of described mature polypeptide (as leading or secretion sequence or proprotein sequence) and as described in maturation protein encoding sequence (with optionally additional coding sequence) additional non-coding sequence (as intron or as described in 5 ' and/or the 3 ' non-coding sequence of encoding sequence of maturation protein).
Therefore, term " polynucleotide of coded polypeptide " or term " nucleic acid of coded polypeptide " should be understood to the polynucleotide of the encoding sequence only comprising described maturation protein or nucleic acid and comprise polynucleotide or the nucleic acid of extra coding and/or non-coding sequence.Term " polynucleotide " and " nucleic acid " use interchangeably.
The present invention also comprises such polynucleotide, and the encoding sequence of wherein said maturation protein can merge identical open reading-frame (ORF) with auxiliary expression polypeptide and from the polynucleotide sequence of host cell secretes; Such as, the leader sequence played a role as the secretion sequence controlled from cell transport polypeptide can merge in such a way.The polypeptide with this leader sequence is called proteinogen or preproprotein and can excises this leader sequence to form the mature form of this protein by host cell.These polynucleotide can have 5 ' elongated area, thus such proteinogen of encoding, it is that maturation protein is added to N-terminal additional amino acid residue.The expression product with former sequence (prosequence) like this is called proteinogen, and it is the inactive form of described maturation protein; But, once this former sequence is cleaved, then leave activated maturation protein.Therefore, such as, polynucleotide of the present invention encoding mature albumen or coding can have the protein of former sequence or have the protein of former sequence and presequence (leader sequence).

As shown in Figure 24, mouse QC and mouse isoQC expresses in whole organs of inspection.Contrary with mouse QC, the variation that between Different Organs, mouse isoQC expresses is less, shows the lower severity of transcriptional regulation.The data that mQC expresses are with previously corresponding to the analysis of ox QC, and wherein use Northern-Blot analyzes described ox QC 1991ProcNatlAcadSciUSA88,10059-10063 such as () Pohl, T..In thalamus, hippocampus and cortex, observe QC expresses the highest.Therefore, QC expresses and mainly detects in neuronal tissue.In peripheral organ is as spleen and kidney, seldom detect that QC expresses.MisoQC also expresses in neuronal tissue, but is in lower level compared with mQC.On the contrary, very similar between the expression level of isoQC and QC in peripheral organ.
Based on the result of transcript concentration, reach a conclusion: associating active (isoQC and QC) should be the highest in brain.Therefore, the highest QC-protein level is present in the organ attacked as alzheimer's disease, Familial British Dementia and Familial Danish Dementia by amyloidosis.
Embodiment 10: suppress people isoQC by heterocycle sequestrant
result
Previous use heterocycle sequestrant as 1,10-phenanthroline and dipicolinic acid have studied to the QC of different sources time m-dependency restraining effect (6,9).Similarly, also time-dependent manner ground is by heterocycle sequestrant 1,10-phenanthroline (Figure 25) and the deactivation of dipicolinic acid's (not shown) for h-isoQC, and this is clear points out that metal relies on activity.In addition, EDTA also suppresses h-isoQC (Figure 25).This and QC form sharp contrast, because EDTA causes noticeable suppression all to people QC, pig QC or mouse QC.But the even more high inhibition of EDTA to hisoQC shows to there is metal-dependant catalysis.
Embodiment 11: the Subcellular Localization using the hisoQC of cellular fractioning research

result
For further confirmation, biochemical analysis is carried out to the QC activity distribution expressed derived from hisoQC and hQC.Natural hisoQC and hQC starting from methionine(Met) I and II expresses respectively in HEK293 cell.After cell grade is separated, uses fluorometry, utilize H-Gln-β NA as substrate, the QC measured in often kind of fraction is active.In cell with empty carrier (pcDNA) transfection, almost measure less than specificity QC active.When expressing natural hisoQC (MetI) and hisoQC (MetII), can detect that QC is active easily, and most high reactivity is present in weight film fraction (MetI:40 ± 2 μm ole/ minute/g; MetII:36 ± 1.5 μm ole/ minute/g) and substratum (MetI:30 ± 2 μm ole/ minute/g; MetII:54 ± 3 μm ole/ minute/g) in.On the contrary, it is active that hQC shows most high specific QC in substratum (1339 ± 76 μm of ole/ minute/g), subsequently display time high specific QC activity (Figure 26 A) in heavy film fraction (251 ± 21 μm of ole/ minute/g).
In addition, calculate absolute activity, show that the expression of hisoQC (MetI) and hisoQC (MetII) mainly causes QC activity in born of the same parents to increase, relic (MetI:1032 ± 9nM/ minute in sight; MetII:1110 ± 10nM/ minute) and heavy film fraction (MetI:374 ± 20nM/ minute; MetII:281 ± 12nM/ minute) increase of middle QC activity.A small amount of QC activity (MetI:27 ± 2nM/ minute is only there is in substratum; MetII:53 ± 3nM/ minute).On the contrary, by hQC express derive QC activity in the medium (1138 ± 65nM/ minute) and in intracellular region room (relic: 1089 ± 14nM/ minute; Heavy film fraction: 583 ± 38nM/ minute) display high reactivity, support the hisoQC Golgi localization (Figure 26 B) as passed through as shown in tissue chemical analysis.
The data obtained by expressing natural enzyme obtain having the hisoQC (MetI and MetII) of carboxyl terminal FLAG label and the support (Figure 26 C) of hQC by expressing further.Compare with mitochondrial labelled protein with Golgi complex, the western blot analysis of the FLAG labeling protein of gained disclose hisoQC (MetI) and hisoQC (MetII) mainly at inner cellular localization in described relic fraction and weight film fraction, and hQC is enriched in substratum, but be also present in described relic fraction and heavy film fraction.Golgi complex and mitochondrial labelled protein video picture are shown that these compartments are present in described relic fraction and heavy film fraction.In addition, 65kDa mitochondrial protein also exists in soluble fractions with smaller portions.
Embodiment 12: to the analysis of hisoQC Golgi retention signal
For understanding fully when the aminoterminal transbilayer helix of prediction is responsible for being detained hisoQC in Golgi complex, by the signal peptide comprising described transbilayer helix starting from MetI and MetII place to meet open reading-frame (ORF) mode and EGFP clones.Gained carrier hisoQC (MetI) SSEGFP and hisoQC (MetII) SSEGFP is at LN405 cells and use confocal laser scanning microscope, CLSM to check in the mode being similar to total length hisoQCEGFP fusion rotein.The expression of hisoQC (MetI) SSEGFP causes as located the viewed identical Golgi complex of total length hisoQC (MetI) EGFP fusion rotein.Again, hisoQC (MetI) SSEGFP is not observed to mitochondrial transport (Figure 27 A).In addition, the expression of amino-terminal truncated version peptide hisoQC (MetII) SSEGFP also causes this protein-enriched in Golgi complex.Similar with hisoQC (MetI) SSEGFP, plastosome EGFP fluorescence (Figure 27 B) can not be recorded to.Therefore, the amino terminal sequence of hisoQC causes this protein be transported to ER film with common interpretative system and cause being trapped in Golgi complex.In addition, because hisoQC (MetII) SSEGFP expresses, Golgi retention signal is roughly located be between the 19th methionine(Met) and Serine the 53rd (from MetI counting amino acid).
Extra topological Analysis discloses the possibility of hisoQC aminoterminal and glycosyltransferase function homology.Glycosyltransferase is II type transmembrane protein, has short endochylema sequence, catalyst structure domain in follow-up transbilayer helix and a large chamber.Obviously, this structural domain structure constructs substantially the same (Figure 28) with the structural domain found misoQC with hisoQC.For numerous glycosyltransferase, determine Golgi retention signal and be positioned at described membrane spaning domain.In addition, for some enzyme in these enzymes, find that the endochylema sequence described in brachymemma does not affect activity or the location of this protein.In a word, provide such evidence, namely hisoQC is II type transmembrane protein, shows in the Golgi complex similar to glycosyltransferase and is detained.

Pearson's bilateral significant correlation in cancer (p=2E-31) and cancer of the stomach (p=0.015) is organized to the further research announcement of QPCT and QPCTL expression level.Dependency (p=0.46) is not observed to QPCT and the QPCTL expression level in thyroid carcinoma.
qPCTL relies on the expression of differentiation phase in cancer of the stomach
For cancer of the stomach, the QPCTL that have studied in the sample representing the different Tumor Differentiation phase expresses.Healthy tissues served as control around tumour.Healthy tissues compares with tumor tissues, and QPCTL significantly higher in display tumor tissues expresses (p=0.04).Undifferentiated cancer of the stomach display is expressed lower than the QPCTL of healthy tissues.Compared with healthy tissues, low differentiation and the good cancer of the stomach to medium differentiation do not show difference (Figure 32) in median.
the expression of QPCT and QPCTL in asynchronous thyroid carcinoma
Express with regard to QPCT and QPCTL, study asynchronous thyroid carcinoma.Be categorized as follicular thyroid carcinoma (FTC), papillary thyroid carcinoma (PTC) and undifferentiated thyroid carcinoma (UTC) according to the name of the World Health Organization (WHO) by stages.From the sample served as control of thyrocele patient.
QPCTmRNA level (median) is higher than (thyrocele: 2100 copy/50ng total serum IgE) in nonneoplastic tissue in the thyroid carcinoma FTC (6700 copy/50ng total serum IgE) and PTC (16000 copy/50ng total serum IgE) of differentiation.UTC has 5400 copy/50ng total serum IgE and higher than the copy number observed in thyrocele 2.5 times.The mRNA copy number of QPCT is significantly higher than thyrocele (p=0.04, Student ' st-inspection) (Figure 33) in whole thyroid tumor.
QPCTLmRNA level in thyroid carcinoma is uniform.Similar to thyrocele (2500 copy/50ng total serum IgE) with the sample of UTC (2500 copy/50ng total serum IgE) from FTC (2600 copy/50ng total serum IgE).The expression of QPCTL in PTC drops to 1900 copy/50ng total serum IgE (Figure 34) slightly.
In a word, QPCT and QPCTL expresses comparably in thyrocele.But in tumor tissues, the expression of QPCT increases, and the expression of QPCTL keeps stable.

the basal expression of QPCT and QPCTL in HEK293, FTC-133 and THP-1
Evaluate in clone HEK293, FTC-133 and THP-1 used basal expression and be subsequent stimuli experiment get ready.The copy number of QPCT and QPCTL transcript is summed up in table 13.
Table 13: the basal expression of QPCT and QPCTL in different clone
the impact that selected stimulator is expressed QPCT and QPCTL
The modulability binding site not describing the promotor of QPCT and QPCTL so far and the signal transduction pathway causing them to regulate.Therefore, different clone and stimulator is used to implement stimulation test.QPCTmRNA in HEK293 cell stimulates horizontally through use TNF-α, HGF and butyric acid and increases.In addition, have studied the regulating effect to the CCL2 as QPCT/QPCTL substrate.TNF-α and butyric acid increase the amount of CCL2 transcript in HEK293.HGF expresses not impact to CCL2.On the contrary, QPCTL does not regulate (Figure 35) by TNF-α, HGF and butyric acid.
In addition, use LPS and TGF-β to stimulate FTC-133 and detect the regulating effect to QPCT, QPCTL and CCL2.In FTC-133, LPS and TGF-β stimulates QPCTmRNA to express, but does not induce QPCTL and CCL2 to express (Figure 36).
This experiment stimulates THP-1 cell to confirm further by use LPS (1 μ g/ml), LPS (10 μ g/ml), TGF-β and TNF-α.As FTC-133 and HEK293 is observed, use different stimulated thing, QPCT may be induced to express, in addition, use LPS and TNF-α to express induction of CCL2.Equally, fail to observe the induction of QPCTLmRNA or check (Figure 37).
In a word, this experiment is disclosed QPCT and can be regulated by group stimulator of in different clone (LPS, TNF-α, HGF, butyric acid and other).On the contrary, QPCTL may not check stimulator stimulation by institute or check, thus implies house keeper's function of QPCTL.
selected stimulator is on the impact of the expression of QPCT and substrate thereof
Induced by multiple stimulator because QPCT expresses, therefore propose such problem: whether QPCT induction occurs with conjunction QPCT substrate CCL2, CCL7, CCL8 together with the induction of CCL13.Therefore, use THP-1 monocyte, use LPS (1 μ g/ml) respectively, LPS (10 μ g/ml), TGF-β (100ng/ml) and TNF-α (100ng/ml) stimulate.THP-1 expresses whole chemokine with basal level, and this is important for comparing at negative control and irriate cell paper.
LPS and TNF-α causes reliably inducing the chemokine and QPCT all checked in THP-1 cell.TGF-β is so ineffective as stimulator, and QPCT, CCL2, CCL7 and CCL8 of induction 2 times at most express.CCL13 is checked (Figure 38) by TGF-β hormesis.
qPCT and QPCTL expresses to be stimulated by hypoxemia
QPCTL expresses and may not be regulated by chemical agent, biologically active peptides or LPS.Therefore, we check QPCTL to express by no by hypoxemia adjustment.As summed up in Figure 39, the expression of QPCTL is induced but not the expression of QPCT in hypoxia-selective ground.Comparatively speaking, hypoxic inducing factor-1 a (HIF1a) is thwarted and reaches 15% (Figure 39 A) and 45% (Figure 39 C).These data show contacting of QPCTL and hypoxemia.
