1.But, mutagenic action is not the only mechanism of hereditary change, the epigenetic mechanism may also play an important role in it.
然而，致突变作用并不是遗传改变的唯一机制，表观遗传基础对此也具有重要作用。DNA甲基化成为外遗传的基础机制已经倍受关注。
2.In some cases, epigenetic changes in people seem to be passed on to subsequent generations.
在某些情况下，人类的表观遗传变异似乎会传递给后代。
3.Epigenetic mechanism might be associated with reduced expression of FHIT in a part cases of esophageal squamous cell carcinomas.
一部分食管癌FHIT基因表达降调则可能要归因于表遗传机制。
4.With epigenetic drugs, it is possible to reverse aberrant gene expression profiles associated with different disease states.
用表观药物，可能逆转与不同疾病状态相关的异常的基因表达谱。
5.At this time I would also like to see some effort "in the Department must live, death epigenetic" shadow.
这时我倒也仿佛看出了点“于绝处活，死而后生”的影子。
6.Recently, the concept that epigenetic, as well as genetic, events might be central to the evolution of human cancer is re-emerging.
最近，这一概念后生，以及遗传，事件可能是中央的演变人类癌症是重新出现。
7.But it's hard to tell in most natural populations whether inheritance is due to DNA sequence variation or epigenetic changes.
但在自然界大多数种群中，很难判断遗传是否源于DNA序列改变或者表观基因变异。
8.The nature of these reactions means epigenetic processes are susceptible to chemical intervention in a way that genetic mutations are not.
从这一过程的特性可以看出，表观遗传调控容易受到化学物质的影响，而遗传突变并不是这样。
9.DNA methylation is one of the most common epigenetic events occurring in human genome and is implicated in cancer.
DNA甲基化是人类基因组发生最为常见的一种表观遗传学事件，因而研究甲基化与肿瘤的关系成为当前分子生物学的热点之一。
10.The main cause of these problems may be attributed to the epigenetic reprogramming of somatic donor genome.
有研究认为，克隆胚胎发育障碍的一个重要的原因是供体细胞的遗传重编程不完全。
