摘要
目的总结DNA甲基化和组蛋白甲基化在肝纤维化中的作用机制。方法综述国内外有关探究肝纤维化过程中DNA甲基化和组蛋白甲基化的文献并进行分析总结。结果 DNA甲基化和组蛋白甲基化都是表观遗传学的重要组成部分,在肝纤维化过程中通过上调或下调某些基因表达,导致后续通路激活或失活,如PTEN、SEPT9、Smad7等在肝纤维化中呈高甲基化且表达降低,Spp1在肝纤维化中就呈低甲基化且表达增加。结论甲基化通过改变基因的表观遗传学从而影响基因的表达,通过对甲基化在肝脏疾病中的作用及机制进行系统而深入的研究可为肝脏疾病的治疗提供新的方向和靶向治疗的位点。
Objective To summarize mechanism of DNA methylation and histone methylation in liver fibrosis.Method The literatures on the DNA methylation and histone methylation during the liver fibrosis were reviewed and analyzed.Results The DNA methylation and histone methylation were the important components of epigenetics.The up-regulation or down-regulation of genes during the liver fibrosis leaded to the activation or inactivation of the subsequent pathways.For example,the PTEN,SEPT9,Smad7,etc.were hypermethylated and the expressions were decreased in the liver fibrosis.The Spp1 was hypomethylated and the expression was increased in the liver fibrosis.Conclusions Methylation affects expression of genes by altering epigenetics of genes.Systematic and in-depth study of role and mechanism of methylation in liver diseases provides a new direction and locations for some target treatments for liver disease.
