Relationships among genome DNA methylation patterns in each upstream CG region on the 22 of genes controlled by epigenetic system and economic traits in Japanese Black cattle
Heritabilities of meat quality in Japanese Black cattle (JB) are between 0.3 and 0.6, and meat of JB has become very popular. However the main mechanism of developing their characteristic features are not well understood although many researchers have them reported SNPs and QTLs. DNA methylation to the upstream region of a start codon controls the expression of many genes. This study’s aims to examine relationships among DNA methylation pattern (DMP) and economic carcass traits in JB. DMP of genome DNA from adipose tissues were analyzed with using specific primers for analyzing each upstream region of the 22 genes controlled by epigenetic system and some TAKARA’s reagent kits. Correlations among some traits and DMPs were highly significant, and specific methylation patterns to C in some CG rich regions may have relation with rib loin thickness and carcass weight.
