查询词典 methylation

HTERT is expressed in cancer cell lines despite promoter DNA methylation by preservation of unmethylated DNA and active chromatin around the transcription start site.

人端粒酶逆转录酶是一种核糖核蛋白酶，由端粒RNA和端粒酶蛋白组成的一种特殊逆转录酶，在激活端粒酶的过程中起限速作用，能以自身RNA为模板合成端粒序列以稳定端粒长度使细胞获得永生，也是人类端粒酶的活性中心，其表达是端粒酶活化的必须前题［2～4］。
