Sodeman, Thomas, Steven F. Bronk, Patricia J. Roberts, Hideyuki Miyoshi, and Gregory J. Gores. Bile salts mediate hepatocyte apoptosis by increasing cell surface trafficking of Fas. Am J Physiol Gastrointest Liver Physiol 278: G992–G999, 2000.—Toxic bile salts induce hepatocyte apoptosis by a Fas-dependent, Fas ligand-independent mechanism. To account for this observation, we formulated the hyp...
