摘要:
为了解克隆罗非鱼SIRT1基因,并分析其在不同组织器官中的表达量和饥饿前后白肌和肝中的表达量,以期为研究罗非鱼基因功能和代谢调控机制提供参考。采用逆转录PCR(RT-PCR)技术由罗非鱼肌肉组织克隆获得罗非鱼SIRT1基因,并用生物信息学方法构建系统进化树,利用实时荧光定量PCR(QRT-PCR)技术对SIRT1在罗非鱼体内表达进行研究。结果显示,SIRT1基因开放阅读框(ORF)为2 109 bp,共编码702个氨基酸,具有保守的DUF、SIR2和TPP保守结构域。进化树分析发现,罗非鱼与伯氏朴丽鱼和红丽鱼的SIRT1首先成簇,说明2个物种的亲缘关系最接近。且SIRT1基因在所检测的组织、器官中均有表达,其中白肌、肠道中表达量最高,且差异显著(P<0.05)。与饥饿组0 d相比,饥饿组7 d的白肌SIRT1基因mRNA的表达无明显变化,而肝表达量却显著增加(P<0.05)。提示罗非鱼SIRT1基因可作为信号转导调控机体糖代谢、脂肪代谢的候选基因之一。
