Phosphorylation of c-Jun stimulated in primary cultured rat liver parenchymal cells by a coplanar polychlorinated biphenyl.

摘要

Phosphorylation of c-Jun was stimulated in primary cultured rat liver parenchymal cells by treatment with a coplanar polychlorinated biphenyl congener, 3,3'4,4'5-pentachlorobiphenyl (PenCB), as well as by epidermal growth factor, but was not stimulated by the non-coplanar form. However, the amount of c-Jun mRNA did not increase with PenCB treatment. PenCB may activate a signal-transducing pathway consisting of protein kinases.
