B细胞淋巴瘤表观遗传学研究进展

表观遗传学是功能基因组学的重要组成部分,是研究DNA序列不发生变化但基因表达发生遗传性改变的一门遗传学分支学科,主要包括DNA甲基化、组蛋白修饰、染色体重塑和微小RNA(miRNA)等基因表达调节机制.表观遗传学调控机制在B细胞淋巴瘤的发展中具有重要作用,有研究表明在B细胞淋巴瘤中常见表观遗传学模式的不稳定性和分子突变.文章从DNA甲基化、组蛋白修饰、miRNA等方面对B细胞淋巴瘤的发生、发展、治疗及预后进行综述.

Research progress of epigenetics in B cell lymphoma

As an important component of functional genomics,epigenetics is a subdiscipline within genetics and refers to heritable changes in gene expression without any alteration in DNA sequence,including DNA methylation,histone modification,chromatin remodeling and microRNA (miRNA).Epigenetic regulation plays a crucial role on the development of B-cell lymphomas,as it has been reported that perturbation of epigenetic pattern and mutations in epigenetic mechanisms are frequent events in B-cell lymphomas.This review summarized the research progress on DNA methylation,histone modification and miRNA as well as their roles in the development,treatment and prognosis of B-cell lymphomas.
