"Epigenetics" is currently defined as "the inheritance of variation (-genetics) above and beyond (epi-) changes in the DNA sequence". Despite the fact that histones are believed to carry important epigenetic information, little is known about the molecular mechanisms of the inheritance of histone-based epigenetic information, including histone modifications and histone variants. Here we review recent progress and discuss potential models for the mitotic inheritance of histone modifications-based epigenetic information.
“表观遗传学”目前被定义为“超越 DNA 序列变化(epi-)的遗传变异(-genetics)”。尽管组蛋白被认为携带重要的表观遗传信息,但关于组蛋白为基础的表观遗传信息的分子机制,包括组蛋白修饰和组蛋白变体的遗传,人们知之甚少。在这里,我们回顾了最近的进展,并讨论了基于组蛋白修饰的表观遗传信息有丝分裂遗传的潜在模型。
