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.
在原代培养的大鼠肝实质细胞中,共平面多氯联苯同系物3,3',4,4',5-五氯联苯(PenCB)以及表皮生长因子可刺激c-Jun的磷酸化,但非共平面形式则无此作用。然而,PenCB处理并未使c-Jun mRNA的量增加。PenCB可能激活了一条由蛋白激酶组成的信号转导途径。
