Objectives miR-200a has been established as a key regulator of HSC activation processes in liver fibrosis. Epigenetic silencing of miR-200a contributing to SIRT1 over-expression has been discussed in breast cancer; however, whether miR-200a controls SIRT1 gene expression in hepatic fibrosis is still unknown. Methods and materials We analyzed miR-200a regulation of SIRT1 expression in CCl4-induced...
Hepatic fibrosis is a common final pathological process in the progression of liver disease, which is primarily due to oxidative stress. Nrf2 is known to coordinate induction of genes that encode antioxidant enzymes. Moreover, Nrf2 expression is largely regulated through the association of Nrf2 with Keap1, which results in cytoplasmic Nrf2 degradation. Conversely, little is known concerning the regulation...
