The effect of concentration on hepatic transport of exogenous epidermal growth factor
Susan Jo Burwen, Mary E. Barker, Ira S. Goldman, Albert L. Jones – 1 March 1985 – Epidermal growth factor (EGF), taken up by rat liver hepatocytes, is primarily transported to the lysosomes and degraded. However, a small but significant percentage of endocytosed EGF is transported by a nonlysosomal pathway and is secreted intact into bile. There is no information as to the mechanisms that regulate the selection of transport pathway and thereby determine the different metabolic fates for EGF.
