廣東地區(qū)鼻咽癌和健康人群中EB病毒EBERs基因多態(tài)性研究
發(fā)布時(shí)間:2022-01-26 02:42
背景和目的EB病毒(Epstein-Barr virus,EBV)編碼小RNA(EBV-encoded small RNAs,EBERs,包括EBER1和EBER2)是所有EBV潛伏類型中表達(dá)最為豐富的RNA,其致癌作用已在淋巴和上皮性腫瘤中得到證實(shí)。我們以往對(duì)山東地區(qū)EBV相關(guān)腫瘤和健康人群中EBERs基因多態(tài)性的研究中發(fā)現(xiàn)了新的EBERs變異型(EB-8m和EB-10m),該變異型雖然不是主要亞型但在NPC中的檢出率高于EBV相關(guān)胃癌和健康人群。本研究旨在了解我國NPC高發(fā)區(qū)廣東地區(qū)NPC和健康人群中EBERs基因變異特征,并與山東地區(qū)實(shí)驗(yàn)數(shù)據(jù)和已發(fā)表EBV基因組序列毒株中的EBERs序列進(jìn)行比較,探討EBERs基因變異與NPC的相關(guān)性,為最終明確EBV基因多態(tài)性與EBV相關(guān)腫瘤的關(guān)系提供實(shí)驗(yàn)依據(jù)。方法收集NPC高發(fā)區(qū)廣東地區(qū)NPC組織標(biāo)本和健康人群咽漱液(Throat washing,TW)標(biāo)本,提取DNA,采用PCR和DNA測序檢測EBERs基因序列,同時(shí)對(duì)山東地區(qū)新增EBV陽性NPC和健康人群標(biāo)本進(jìn)行EBERs基因序列檢測,應(yīng)用Lasergene軟件對(duì)EBERs序列進(jìn)行對(duì)比分...

Only nucleotides different from B95-8 areindicated. B, The sequence analysis for multiple infection of different EBERs variants. In dualinfection with EB-6m and EB-8m, double signals were found at nucleotides 6866, 6884, 6886, 6911,6944, 6999, 7001, 7012, 7016 and 7048, which simultaneously showed the signature mutations ofEB-6m and EB-8m. In dual infection with EB-6m and B95-8, double signals were found at nucleotides6808, 6884, 6886, 6911, 6944 and 7123, which simultaneously showed the signature mutations ofEB-6m and B95-8.1.2 系統(tǒng)進(jìn)化樹分析對(duì)廣東地區(qū) 130 條序列和山東地區(qū) 187 條 EBERs 序列比對(duì)后,共出現(xiàn) 61 條不同序列,以 61 條序列和標(biāo)準(zhǔn)株 B95-8 序列繪制系統(tǒng)進(jìn)化樹,與圖 1 和圖 2 對(duì)應(yīng),每一種人群中相同序列以一個(gè)樣本作為代表,與該序列相同的標(biāo)本數(shù)列于標(biāo)本編號(hào)后括號(hào)內(nèi)。系統(tǒng)樹分為 2 大枝,每一枝又分別包含兩個(gè)亞組,四個(gè)亞組分別對(duì)應(yīng) EB-6m、B95-8、EB-10m和EB-8m四種變異型。EB-6m和B95-8型距離較近,EB-8m和EB-10m距離較近(圖 4)。EB-10m 在 161 bp 非轉(zhuǎn)錄區(qū)前的 4 個(gè)堿基突變與 EB-6m 相同,而非轉(zhuǎn)錄區(qū)后的 6 個(gè)堿基突變與 EB-8m 相同,似乎是 EB-6m 和 EB-8m 的重組株。
