Transcriptional regulation of hepatic stellate cell activation.
The hepatic stellate cell (HSC) is now well established as the key cellular element involved in the development of hepatic fibrosis and because of this there is considerable interest in establishing the molecular events that trigger and perpetuate HSC activation. HSC activation at the level of gene transcription requires the coordinated activity of several key transcriptional regulators of the ...
متن کاملEpigenetic Changes during Hepatic Stellate Cell Activation
BACKGROUND AND AIMS Hepatic stellate cells (HSC), which can participate in liver regeneration and fibrogenesis, have recently been identified as liver-resident mesenchymal stem cells. During their activation HSC adopt a myofibroblast-like phenotype accompanied by profound changes in the gene expression profile. DNA methylation changes at single genes have been reported during HSC activation and...
متن کاملMitochondrial uncouplers inhibit hepatic stellate cell activation
BACKGROUND Mitochondrial dysfunction participates in the progression of several pathologies. Although there is increasing evidence for a mitochondrial role in liver disease, little is known about its contribution to hepatic stellate cell (HSC) activation. In this study we investigated the role of mitochondrial activity through mild uncoupling during in vitro activation of HSCs. METHODS Cultur...
متن کاملEpigenetic regulation during hepatic stellate cell activation
Background Hepatic stellate cells (HSC) have recently been identified as liver-resident mesenchymal stem cells and are thought to contribute to liver repair and fibrogenesis [1]. Quiescent HSC are located in the space of Disse and store vitamin A in characteristic lipid droplets. During their activation HSC lose their vitamin A stores and adopt a myofibroblast-like phenotype. This activation of...
