Decrease of cell population of the G₁/S transition phase reduced the apoptosis rate. TatBim-PS induced apoptosis efficiently in the G₁/S transition phase. (A) Cell cycle population and light-dependent apoptosis after treatment with thymidine. Scale bar, 50 µm. (B) Apoptosis rate after the treatment with thymidine. Data are shown as the mean ± SEM (n = 3; each of the analyzed areas included 123 cells on average). *p < 0.05 by analysis of variance followed by Student's t-test. (C) Cell cycle population after thymidine treatment. Data are shown as the mean (n = 3; each of the analyzed areas included 118 cells on average).
