Core Tip
Core tip: Both oxidative and nitrosative stress are associated with ongoing manifestations of chronic cholestasis, and in particular, primary biliary cirrhosis. Abnormalities in nitric oxide metabolism and thiols oxidation already occur at early stages, thus leading to the hypothesis that these biochemical events play a pathogenic role in primary biliary cirrhosis. The association of these metabolic abnormalities with the progression of the disease may indicate some biochemical parameters as early diagnostic markers of disease evolution, and may open up the potential for pharmacological intervention to inhibit intra- and extra-cellular stress events for resuming hepatocellular functions. This article summarizes the current knowledge by outlining molecular mechanisms of the disease related to these stress events.
