Resumen:
Liver regeneration is the most important reaction of the liver to an injury. Indeed, the liver possesses an extraordinary regenerative capacity orchestrated by a highly coordinated response of all the different cell types in order to recover the tissue lost, while maintaining homeostasis and all the hepatic functions. To achieve this impressive physiological accomplishment, the liver experiences a transient but precisely controlled transcriptional reprogramming that allows the simultaneous activation and silencing of multiple genes at different stages of the regeneration process. Epigenetic events play a fundamental role in the organization of chromatin architecture and hence in the tight control of gene transcription. In this review, we will summarize the most relevant epigenetic modifications associated with the critical changes in gene expression and cellular behavior occurring during liver regeneration. We will discuss the relevance of DNA methylation, histone modifications, and chromatin remodelers, and the interplay between these epigenetic events, during the regeneration process, mainly after partial hepatectomy or after chemical injury.
