摘要:

试验旨在克隆获得PDK4、FGF10基因,并研究大白猪与从江香猪不同组织中PDK4、FGF10基因mRNA的表达差异。采用RT-PCR分别克隆从江香猪PDK4、FGF10基因并进行生物信息学分析,利用实时荧光定量PCR技术检测PDK4、FGF10基因在大白猪和从江香猪不同组织中mRNA的相对表达量。结果显示,从江香猪PDK4基因的编码区全长1 224 bp,编码407个氨基酸;FGF10基因的编码区全长636 bp,编码211个氨基酸。经BLAST软件进行同源性比对,发现从江香猪PDK4基因与羊、马、人的核苷酸序列同源性分别为93%、92%和91%;FGF10基因与羊、牛、人、鼠的核苷酸序列同源性分别为94%、93%、93%和90%。由PDK4基因系统进化树可知,从江香猪与牛、绵羊亲缘关系较近;由FGF10基因系统进化树可知,从江香猪与绵羊、牛、人、猕猴亲缘关系较近,与小鼠和鸡亲缘关系较远。实时荧光定量PCR结果显示,在从江香猪不同组织中,PDK4基因在肾脏中的表达量最高,在胃和脂肪中表达量较高,FGF10基因在胃中表达量最高,在肾脏和脂肪中表达量较高,两个基因在背最长肌中的表达量均最低;在大白猪的不同组织中,PDK4、FGF10基因在脂肪中的表达量均最高,PDK4基因在背最长肌中的表达量最低,而FGF10基因在心脏中表达量最低。本试验成功克隆了从江香猪PDK4、FGF10基因,并检测了其在大白猪与从江香猪不同组织中的表达,为进一步研究PDK4、FGF10基因在脂质代谢及脂肪沉积等方面的调控作用提供科学依据。

Abstract:

The objective of this study was to clone PDK4 and FGF10 genes, and investigate the expression level of PDK4 and FGF10 genes mRNA in different tissues of Large White pig and Congjiang Xiang pig. The PDK4 and FGF10 genes were cloned by RT-PCR and analyzed by bioinformatics, the relative expression of PDK4 and FGF10 genes were detected by Real-time PCR. The results showed that the coding region of PDK4 gene was 1 224 bp, encoding 407 amino acids; The coding region of FGF10 gene was 636 bp and encoded 211 amino acids. The homologies of nucleotide sequences of PDK4 gene with sheep, horse and human were 93%, 92% and 91%,respectively. The homologies of nucleotide sequences of FGF10 gene with sheep, cattle, human and mouse were 94%,93%, 93% and 90%, respectively. The phylogenetic tree of PDK4 gene showed that the genetic relationship of Congjiang Xiang pig, cattle and sheep were very close, the phylogenetic tree of FGF10 gene indicated that the genetic relationship of Congjiang Xiang pig, cattle, sheep, human and macaque were very close, but the genetic relationship of Congjiang Xiang pig, rat and chicken were far away. Real-time PCR results showed that, in different tissues of Congjiang Xiang pig,PDK4 gene expression in kidney tissue was higher than other tissues, with a higher expression in stomach and adipose as well,FGF10 gene expression in stomach tissue was higher than other tissues, with a higher expression in kidney and adipose as well, but both of PDK4 and FGF10 genes expression were the lowest in longissimus dorsi. In different tissues of Large White pig, both of PDK4 and FGF10 genes were expressed the highest in adipose than other tissues, PDK4 gene expression in longissimus dorsi was the lowest, while the FGF10 gene expression the lowest in heart. This study successfully cloned the PDK4 and FGF10 genes of Large White pig and Congjiang Xiang pig,and detected the relative expression of PDK4 and FGF10 genes in different tissues of Large White pig and Congjiang Xiang pig, and also provided scientific basis for further study on regulation of PDK4 and FGF10 genes on lipid metabolism and deposition.
