In this experiment, the G1 and S-phase ratios of HeLa and PC3 tumor cells were down-regulated and the G2 phase was increased under the effect of 3-DSC, while enhanced expression of CDK1 and CDK2 proteins were detected, and 3-DSC was also found to promote p53 protein expression in HeLa and PC3 cells. Here, CDK1 is linked to neoplasm.
