To investigate the effect of ionizing radiation on p16 gene transcription and protein expression in EL-4 cells in vitro, RT-PCR semi-quantity method was applied to determine the p16mRNA level and immunocytochemistry (ICC) was employed to measure the p16 protein expression. The time-course experiments showed that the p16 mRNA level increased at 2—48h in EL-4 cells, and the p16 protein expression increased significantly in EL-4 cells (,p,<,0.01) at 12h after 2.0Gy X-irradiation. The dose-effect experiments showed that the p16mRNA level increased with the dose, and the p16 protein expression increased significantly (,p,<,0.01) with the dose in 2.0 - 6.0Gy range. The results suggested that the increase of p16 gene transcription and protein expression in EL-4 cells might play role in G1 arrest induced by ionizing radiation in vitro.
