| 摘 要： | 克隆半滑舌鳎(Cynoglossus semilaevis)的1种细胞凋亡抑制因子survivin基因,并对其序列及表达模式进行分析.结果表明,该基因cDNA 序列全长704 bp(GenBank登录号为EU499314),包括86 bp5'非翻译区,444 bp开放阅读框以及含 poly(A)信号的174 bp的3'非翻译区,编码147个氨基酸.氨基酸序列同源性分析表明,半滑舌鳎survivin氨基酸序列与斑马鱼、非洲爪蟾、鸡、小鼠和人survivin氨基酸序列的同源性分别达到了63.3%,49.0%,43.7%,43.6%和41.5%.RT-PCR分析表明,survivin基因在半滑舌鳎成体雌鱼卵巢中大量表达,在雌鱼的肾脏中微量表达,在其它雌鱼的组织中无表达,在雄性的任何组织中均无表达.该基因在受精卵、多细胞和囊胚3个胚胎发育的早期阶段,大量表达,而随着胚胎发育的进程,survivin基因的表达逐渐减少,在孵化前尾芽期胚胎中只有微量表达,在孵化后5 d的仔鱼中,几乎检测不到survivin基因的表达.表明该基因可能参与卵子形成和胚胎的早期发育.

| Abstract: | Survivin is one of the members of inhibitor of apoptosis(IAPs) which only contains one BIR functional region.Survivin expresses highly in the embryo tissues and rapidly dividing cells,while is hardly detected in the regular growing cells.We cloned the full length cDNA of survivin from Cynoglossus semilaevis and sequenced it.Sequence analysis revealed that the fragment of survivin cDNA contained 444 bp open reading frame(ORF),86 bp 5' untranslated region(UTR) and 174 bp 3'UTR.Alignment analysis showed the am... |
