The activated c-Ha-ras oncogene induced AP1-site DNA-binding activity in F9 cells. This induction appeared to be due, at least in part, to the induction of c-jun transcription. Both activated c-Ha-ras and c-jun induced the differentiation of F9 cells to endoderm-like cells. Thus, AP1 appears to play a key role in the initial stage of F9 cell differentiation.
活化的c-Ha-ras癌基因在F9细胞中诱导了AP1位点的DNA结合活性。这种诱导作用似乎至少部分归因于c-jun转录的诱导。活化的c-Ha-ras和c-jun均诱导F9细胞分化为内胚层样细胞。因此,AP1似乎在F9细胞分化的初始阶段起着关键作用。
