摘要
To compare the mode of action of ras p21 with those of protein kinases A and C in the regulation of gene expression in NIH/3T3 cells, we investigated the transcriptional activity of various enhancer/promoters and enhancer motifs in the cells transfected with the c-Ha-rasval12 complementary DNA (cDNA). The results indicate that the c-Ha-rasval12 protein stimulates the enhancer/promoters of the c-fos gene, the metallothionein IIA gene, the simian virus 40 (SV40) virus genome and the Rous sarcoma (RS) virus genome, and the serum-response element and the 12-O-tetradecanoylphorbol-13-acetate (TPA)-response element in a manner independent of protein kinases A and C in NIH/3T3 cells. © 1990.
