[Epigenetics and liver fibrogenesis].

Epigenetic modification refers to a variety of regulating processes that may induce the changes in gene expression without altering DNA sequence. Epigenetic mechanisms including DNA methylation, histone modification, and regulatory non-coding RNAs are involved in hepatic stellate cell activation and liver fibrogenesis. A deep understanding of epigenetic mechanisms in liver fibrosis helps to identify new markers and therapies for liver fibrosis.
