Induction of cytochrome P enzymes and generation of protein-aldehyde adducts are associated with sex-dependent sensitivity to alcohol-induced liver disease in micropigs. Mechanisms of caspase activation and inhibition during apoptosis. 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 and altered cytokine production, increased endotoxin levels and activation of Kupffer cells, mobilization of iron, modulation of the antioxidant defense, particularly mitochondrial glutathione GSHone electron oxidation of ethanol to 1-hydroxy-ethyl radical, and induction of CYP2E1.

While most ethanol is oxidized by ADH when hepatopstia levels are low; cytochrome PE1 CYP2E1an ethanol inducible from in the microsomal compartment of hepatocytes and Kupffer cells, plays a more important role in ethanol oxidation at high concentrations of ethanol binge drinking and in chronic alcohol consumption chronic alcoholism Transforming growth factor beta and the liver.

Activation of stellate cells is mediated by factors released from hepatocytes and Kupffer cells as they produce reactive oxygen species, hepatopatiz oxide, cytokines, growth factors, and cyclooxygenase and lipoxygenase metabolites, which provide pivotal paracrine effects in the liver milieu.
