Chronic alcohol abuse causes liver disease that progresses from simple steatosis through stages of steatohepatitis, fibrosis, cirrhosis, and eventually hepatic failure. In addition, chronic alcoholic liver disease (ALD), with or without cirrhosis, increases risk for hepatocellular carcinoma (HCC). Acetaldehyde, a

Microcompartments are loose protein cages that encapsulate enzymes for particular bacterial metabolic pathways. These structures are thought to retain and perhaps concentrate pools of small, uncharged intermediates that would otherwise diffuse from the cell. In Salmonella enterica, a microcompartment encloses

Aldehyde dehydrogenases (ALDHs) catalyse the conversion of toxic aldehydes into non-toxic carboxylic acids. Of the 21 ALDHs in mice, it is the ALDH3 family members (ALDH3A1, ALDH3A2, ALDH3B1, ALDH3B2 and ALDH3B3) that are responsible for the removal of lipid-derived aldehydes.
