Abstract

The transformation frequency of mouse BALB/3T3 cells was significantly enhanced after transfection with an activated ras oncogene (v-Ha-ras) followed by treatment with a tumor promoter, 12-O-tetradecanoyl-phorbol-13-acetate (TPA), suggesting that the ras oncogene acted as an initiator in two-stage carcinogenesis. A cell clone (Bhas42) containing the ras oncogene was isolated from the ras-transfected BALB/3T3 cells. Bhas42 cells were flat and showed contact inhibition, but the addition of TPA to quiescent Bhas42 cultures resulted in a dramatic change of cell morphology to spindle shape, doubling of the cell population, and increased DNA synthesis.

摘要

用活化的ras癌基因(v-Ha-ras)转染小鼠BALB/3T3细胞,随后用肿瘤促进剂12-O-十四烷酰佛波醇-13-乙酸酯(TPA)处理后,其转化频率显著提高,这表明ras癌基因在两阶段致癌过程中起启动子的作用。从经ras转染的BALB/3T3细胞中分离出一个含有ras癌基因的细胞克隆(Bhas42)。Bhas42细胞扁平,表现出接触抑制,但向静止的Bhas42培养物中添加TPA会导致细胞形态急剧变为纺锤形,细胞数量加倍,并增加DNA合成。
