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.
