Epigenetic modifications serve as a means of intermediate gene expression control and nutritional inputs may modify methylation patterns in regulatory regions of genes. Therefore, we proposed that folate availability affects adipocyte development and metabolism through impacting the one-carbon cycle and subsequent DNA methylation patterns. This study was aimed to verify the effects of folic acid on lipid metabolism both in vivo and in primary preadipocytes of Beijing-You chickens. We evaluated the effects o...
