Abstract

Cardiac fibrosis represents an adoptive response in the heart exposed to various stress cues. While resolution of the fibrogenic response heralds normalization of heart function, persistent fibrogenesis is usually associated with progressive loss of heart function and eventually heart failure. Cardiac fibrosis is regulated by a myriad of factors that converge on the transcription of genes encoding extracellular matrix proteins, a process the epigenetic machinery plays a pivotal role. In this mini-review, we summarize recent advances regarding the epigenetic regulation of cardiac fibrosis focusing on the role of histone and DNA modifications and non-coding RNAs.

Keywords: Cardiac fibrosis; Epigenetics; Endothelial cell; Fibroblast

Core tip: Cardiac fibrosis contributes to the increased accidence of sudden cardiac death, heart failure and arrhythmia. The molecular mechanisms underlying cardiac fibrosis remain obscure. Seminal studies have revealed complex pathways associated with cardiac fibrosis. How histone/DNA modifying enzymes and microRNAs fine-tune these events are actively pursued by investigators. This review provides an overview on recent advances regarding the epigenetic regulation of fibrosis.
