摘要:
为初步阐明gga-miR-26a在鸡脂肪沉积中的作用,以矮小品系S3系(DW)和隐性白羽鸡(RR)为试验素材,采用实时荧光定量PCR法检测gga-miR-26a在2个品种不同生长发育时期肝脏、腹脂及腿肌组织,腹脂和肌内脂肪细胞增殖期和分化期的表达变化,并利用生物信息学的方法,对gga-miR-26a靶基因进行预测和分析。结果表明,gga-miR-26a在S3系鸡(DW)和隐性白羽鸡(RR)16 W时肝脏组织中的表达存在显著的品种差异,S3系鸡在5个发育阶段表达均高于隐性白羽鸡;腹脂组织中,gga-miR-26a在0 W时存在极显著的品种差异(P<0.01)且显著高于其他周龄;gga-miR-26a在腿肌组织中的表达无显著的品种差异(P>0.05);在脂肪细胞中,gga-miR-26a在分化4 d的表达显著高于增殖期(P<0.05)。利用TargetScan、miRDB、miRmap等3个软件对gga-miR-26a靶基因进行预测,共预测到163个交集靶基因;GO及KEGG分析提示gga-miR-26a可能通过靶向调节PTEN、ULK2和PRKCD的表达,进而调控鸡的脂肪沉积。综上所述,gga-miR-26a在2个品种鸡脂肪相关组织及脂肪细胞中均有表达,且具有显著的品种差异;gga-miR-26a参与了鸡的脂肪沉积过程,PTEN、ULK2和PRKCD可能是gga-miR-26a调控脂肪沉积的预测靶基因。
