摘要 为了解FAM134B基因的表达规律以及对绵羊肉质的影响,试验以敖汉细毛羊组织样本为材料,运用实时荧光定量PCR技术对不同组织FAM134B mRNA的表达情况进行研究,并对肌肉组织中FAM134B mRNA表达量与肌内脂肪含量进行关联分析。结果表明:FAM134B基因在所选的绵羊心脏、肝脏、脾脏、肺脏、肾脏、背最长肌、股二头肌、皮下脂肪、腹部脂肪器官组织中均有表达,其中在肝脏中的表达量最高,而在肺脏中的表达量最低。关联分析显示,在绵羊背最长肌、股二头肌中FAM134B基因的mRNA表达水平与肌内脂肪含量呈极显著正相关(P<0.01)。初步推测,FAM134B基因可能对绵羊肌内脂肪沉积具有重要的调控作用。
