摘要: 为了探究膜联蛋白A2(ANXA2)基因单核苷酸多态性(SNP)及其在组织中的表达差异,以180日龄的藏猪、大约克猪作为试验对象,检测ANXA2 基因在肝脏、腹脂和背脂组织上mRNA表达差异,并对ANXA2基因的5′侧翼区进行多态性分析。结果显示,在ANXA2基因5′侧翼区筛选到4个SNP位点,g.111574291G> A、g.111574499C>T、g.111574522G>C和g.111574638A>G,且藏猪与大约克猪等位基因频率差异显著(P<0.05)。在肝脏中,藏猪和大约克猪ANXA2基因的mRNA表达趋势基本一致;在背脂和腹脂中,藏猪ANXA2基因的mRNA表达量极显著低于大约克猪(P<0.01)。综上,ANXA2基因可能是调控脂肪沉积和脂肪代谢的重要候选基因。

Abstract: In order to explore the single nucleotide polymorphism(SNP)of Annexin A2(ANXA2)gene and its expression differences in tissues,180‑day‑old Tibetan pigs and Yorkshire pigs were used as experimental objects to detect the mRNA expression difference of ANXA2 gene in liver,abdominal fat and dorsal fat tissus,and the polymorphism of 5′flanking region of ANXA2 gene was analyzed. The results showed that four SNP sites were screened in the 5′flanking region of ANXA2 gene,g.111574291G>A,g.111574499C>T,g.111574522G>C and g.111574638A>G. There was a significant difference in allele frequency between Tibetan pigs and Yorkshire pigs(P<0. 05).In liver tissue,the mRNA expression trend of ANXA2 gene in Tibetan pigs and Yorkshire pigs was basically the same;In abdominal fat and dorsal fat tissus,the mRNA expression of ANXA2 gene in Tibetan pigs was significantly lower than that in Yorkshire pigs(P<0. 01).In conclusion,ANXA2 gene may be an important candidate gene for regulating fat deposition and fat metabolism.
