abstract：:Mouse C3H 10T1/2 cells are most sensitive to radiation-induced neoplastic transformation in the G2/M-phase of the cell cycle. When synchronized 10T1/2 cells were exposed to phorbol 12-myristate 13-acetate (TPA) after irradiation, transformation of cells not in the transformation-sensitive window was enhanced, but tran...
