牛人在我身邊(1)
2009年初,安徽醫(yī)科大學(xué)皮膚病研究所張學(xué)軍教授研究團(tuán)隊通過全基因組關(guān)聯(lián)分析(Genome Wide Association Study,GWAS)方法,,在國際上首次發(fā)現(xiàn)銀屑病易感基因LCE,。之后,他們通過深入分析數(shù)據(jù),,聯(lián)合歐美銀屑病遺傳研究團(tuán)隊,,采用多中心、多種族,、大樣本,,在30000余份銀屑病和對照中繼續(xù)開展易感基因深層發(fā)掘,進(jìn)一步發(fā)現(xiàn)了6個銀屑病新的易感基因,;并發(fā)現(xiàn)其中3個基因在中國人群、美國人群和德國人群銀屑病易感性的異同,;2個基因與早發(fā)型銀屑病密切相關(guān),;提出了銀屑病發(fā)病的遺傳異質(zhì)性。
據(jù)介紹,,這項研究得到國家自然科學(xué)基金重點(diǎn)項目,、國家“973”計劃項目、“863”計劃項目和美國NIH項目支持,。研究實(shí)現(xiàn)了亞洲人群,、歐美人群的國際性合作,突破了疾病易感基因研究人群單一的局限,,研究結(jié)果具代表性和科學(xué)性,。
同時,由于目前國際上已經(jīng)發(fā)現(xiàn)并被廣泛公認(rèn)的銀屑病易感基因近20種,,本次發(fā)現(xiàn)6個新易感基因,,對于構(gòu)建銀屑病易感基因譜,深入了解銀屑病的發(fā)病機(jī)制將起到積極推動作用,,也為疾病預(yù)警,、遺傳咨詢、臨床診療,、新藥開發(fā)等提供了科學(xué)依據(jù),。
GWAS是目前國際上公認(rèn)的搜尋和鑒定復(fù)雜疾病易感基因的研究方法。近5年來,,中外科學(xué)家通過GWAS研究,,在近200種包括腫瘤、精神疾病,、代謝疾病,、免疫疾病、傳染病等復(fù)雜疾病中發(fā)現(xiàn)近3000個疾病易感基因,推動了人類對復(fù)雜疾病遺傳學(xué)發(fā)病機(jī)制的認(rèn)識,。
安醫(yī)大皮膚病研究所從2007年開始在國內(nèi)開展復(fù)雜疾病GWAS研究,,先后利用GWAS在國際上首次發(fā)現(xiàn)漢族人銀屑病、白癜風(fēng),、麻風(fēng),、系統(tǒng)性紅斑狼瘡等皮膚復(fù)雜疾病易感基因,深入揭示了這些復(fù)雜疾病的分子發(fā)病機(jī)制,,使我國銀屑病,、白癜風(fēng)、麻風(fēng)和系統(tǒng)性紅斑狼瘡等皮膚復(fù)雜疾病易感基因研究處于世界領(lǐng)先水平行列,。(生物谷Bioon.com)

We extended our previous genome-wide association study for psoriasis with a multistage replication study including 8,312 individuals with psoriasis (cases) and 12,919 controls from China as well as 3,293 cases and 4,188 controls from Germany and the United States and 254 nuclear families from the United States. We identified six new susceptibility loci associated with psoriasis in the Chinese study containing the candidate genes ERAP1, PTTG1, CSMD1, GJB2, SERPINB8 and ZNF816A (combined P < 5 × 10?8) and replicated one locus, 5q33.1 (TNIP1-ANXA6), previously reported (combined P = 3.8 × 10?21) in the European studies. Two of these loci showed evidence for association in the German study at ZNF816A and GJB2 with P = 3.6 × 10?3 and P = 7.9 × 10?3, respectively. ERAP1 and ZNF816A were associated with type 1 (early onset) psoriasis in the Chinese Han population (test for heterogeneity P = 6.5 × 10?3 and P = 1.5 × 10?3, respectively). Comparisons with the results of previous GWAS of psoriasis highlight the heterogeneity of disease susceptibility between the Chinese and European populations. Our study identifies new genetic susceptibility factors and suggests new biological pathways in psoriasis.
