Abstract excerpt
In alpha1-antitrypsin (alpha1-AT) deficiency, a mutant form of alpha1-AT polymerizes in the endoplasmic reticulum (ER) of liver cells resulting in chronic hepatitis and hepatocellular carcinoma by a gain of toxic function mechanism. Although some aspects of the cellular response to mutant alpha1-AT Z have been partially characterized, including the involvement of several proteasomal and nonproteasomal mechanisms...
