| 摘 要： | 从DNA甲基化修饰、组蛋白甲基化和乙酰化修饰、基因印记和RNA干扰等几个方面,综述了表观遗传学的基本机制及其对哺乳动物生殖细胞发育分化的影响。表观遗传学对于动物机体生长、代谢及功能的正常维持具有重要作用,其中任何方面的异常都会导致体细胞和生殖细胞的生长分化调控失常,甚至引发疾病。

| Abstract: | We reviewed the fundamental mechanism of epigenetics and its effects on the differentation and development of germ cells,which involves DNA methylation,histone acetylation and methylation,gene imprinting,RNA interference,and so on.Epigenetics is mainly on the study of the heritable phenotype changes which is not strictly dependent on DNA sequence.It plays an important role in the specification and differentiation of germ cell.These disorders can affect the renewal and differentiation of normal and germ cell... |
