摘要:
为明确FBXO32基因在高原藏猪与大约克猪肌肉中的表达差异性,选取这2个猪种作为试验动物,采用双脱氧测序技术对藏猪(33头)、大约克猪(32头)FBXO32基因的5′UTR启动子区进行单核苷酸多态性(SNPs)筛选,利用实时荧光定量聚合酶链式反应(RT-qPCR)技术检测FBXO32基因在藏猪、大约克猪腿肌及背最长肌组织中mRNA的相对表达量。研究结果表明,在FBXO32基因的5′UTR启动子区筛选到了G-257A和A-556G这2个SNPs位点,且SNPs位点在2个猪种群体间的基因型频率有着显著性差异(P<0.05);通过转录因子预测,发现这2个SNPs位点与肌细胞的更新、分化和增殖相关,推测FBXO32基因的SNPs位点是调控肌肉生长的关键位点;藏猪腿肌、背最长肌组织中FBXO32基因的mRNA相对表达量都显著高于大约克猪(P<0.05),由此推测FBXO32基因可以负向调控肌肉生长,这可能是导致高原藏猪生长速度慢的主要原因之一。本研究结果为进一步探究FBXO32基因在猪肌肉生长相关的调控机制提供了必要的理论依据。
