TNF-alpha contributes to the pathogenesis of ethanol-induced gastric damage in cirrhotic rats. Alcohol ; 30 2: Physiol Rev ; Gastroenterol ; 2: Transforming growth factor beta and the liver. Liver cirrhosis is a prevalent disease around the world. As the liver becomes fibrotic, the total hepatopatiia of collagens and non-collagenous components increases and it is accompanied by a shift in the type of ECM in the subendothelial space from the normal low density basement membrane-like matrix to interstitial type matrix containing fibril-forming collagens mostly collagens I and III Chronic alcohol abuse is the main reason for developing liver fibrosis and eventually cirrhosis, a major cause of death worldwide 1,2.
