| Research Abstract |
We demonstrated that (1) bovine oocytes and preimplantation embryos express methylation pathway enzymes ; (2) among the metabolites in methylation pathway, homocysteine affects the level of DNA methylation, and methionine, thorough its conversion to S-adenosylmethionine, is involved in morula-to-blastocyst transition during bovine preimplantation development. The existence and importance of methylation pathway in bovine preimplantation development were suggested.
