Hepatocyte oxidant stress and alcoholic liver disease. Conde de la Rosa, H. Moshage 1 y N. Acute and chronic alcohol consumption increases the production of reactive oxygen species ROSand enhances lipid peroxidation of lipids, proteins, and DNA. The mechanism by which alcohol causes cell injury is still not clear but a major role for ROS and lipid peroxidation-end products is considered.

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.

These pathways are not exclusive of one another and it is likely that several, indeed many, systems contribute to the ability of ethanol to induce acloholica state of oxidative stress. Algunas de estas especies por ejemplo, O 2.

En condiciones normales, el O 2. Las tres isoformas dismutan el O 2. Los hepatocitos expresan Fas CD95 pero no ligando Fas. En la gran familia de las MAPK se han identificado tres subgrupos: La familia de la PI3-cinasa es una superfamilia que comprende tres clases distintas de enzimas vinculadas con la supervivencia celular. Las enzimas de la clase I se han clasificado y subdividido en dos grupos de PI3-cinasas: Se han lacoholica tres isoformas distintas de la HO Tumour necrosis factor related apoptosis inducing ligand TRAIL induces hepatic steatosis in viral hepatitis and after alcohol intake.
