猪脂肪沉积候选基因AOC3、PPARG1及SOD3 DNA甲基化差异研究

Abstract

Abstract:

This reasearch intended to find out the link between intramuscular fat（IMF）and DNA methylation level of AOC3,PPARG1 and SOD3 genes,and to make clear how DNA methylation influcence the fat deposition process.We used 10 F2 pigs with the extreme IMF of the Yorkshire pig×Min pig resource population.Longissimus muscle tissues were collected to find out the connection between the methylation level and IMF by using BSP.The results showed that there were no significant methylation differences in all the three candidate genes between the IMF extreme groups,which suggested that the phenotypic differences in this population might not be controlled by the degree of the methylation level,further study was still needed.

Key words: pig; DNA methylation; fat deposition; AOC3 gene; SOD3 gene; PPARG1 gene
