Description:
The tumor promoters 12-O-tetradecanoyl-phorbol-13-acetate and teleocidin markedly enhanced the transformation of C3H 10T1/2 mouse fibroblasts when these cells were transfected with the cloned human bladder cancer c-rasH oncogene. Transfection studies with the drug resistance marker gpt and time course studies indicate that this enhancement is not simply an effect on the process of DNA transfection. These findings, together with parallel studies with NIH 3T3 fibroblasts, also indicate that the competence of animal cells for DNA transfection is a function of the recipient cell line, the transfected marker, and the growth conditions. Our findings suggest that during multistage carcinogenesis tumor promoters may complement the function of activated cellular oncogenes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hsiao, W L -- Gattoni-Celli, S -- Weinstein, I B -- CA 26056/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Nov 2;226(4674):552-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6436974" target="_blank"〉PubMed〈/a〉
