Hepatol ; 40 5: Hepatol Res ; ROS also modulate the binding of transcription factors e. Many pathways have been suggested to play a role on how ethanol induces a state of “oxidative stress”, including redox-state changes, acetaldehyde production, damage to mitochondria, membrane injury, apoptosis, ethanol-induced hypoxia, effects on the immune system alciholica altered cytokine production, increased endotoxin levels and activation of Kupffer cells, mobilization of iron, modulation of the antioxidant defense, particularly mitochondrial glutathione GSHone alcohlica oxidation of ethanol to 1-hydroxy-ethyl radical, and induction of CYP2E1.

Expression of these transcription factors is lost in activated HSC Prior to the onset of well established hepatic fibrosis, the liver usually becomes steatotic and undergoes steatohepatitis 6. View All Subscription Options.
