Chronic ethanol administration impairs receptor‐mediated endocytosis of epidermal growth factor by rat hepatocytes
Douglas D. Dalke, Michael F. Sorrell, Carol A. Casey, Dean J. Tuma – 1 November 1990 – The effects of chronic ethanol administration on the receptor‐mediated endocytosis of epidermal growth factor were studied in isolated rat hepatocytes. In initial experiments, it was demonstrated that significantly less ligand was bound by hepatocytes isolated from rats fed an ethanol liquid diet for 5 to 7 wk than by cells isolated from chow‐fed or pair‐fed controls. Reduced binding was shown to be primarily caused by a decreased number of surface receptors rather than by changes in receptor affinity.
