Effects of melatonin and U0126 on cell proliferation. The cells were exposed to U0126 (20 µM), melatonin (10 µM) alone and both of them for 24 h. Cell proliferation was measured by the CCK-8 assay. Results are indicated as the relative percentage of control cells. The results are represented as the means ± SEM of three independent experiments. ** p < 0.01, compared with control cells; # p < 0.05, compared with the melatonin treatment group; && p < 0.01, compared with the U0126 treatment group.
