Expression of p-ERK1/2 induced by 10 µM melatonin in hFOB 1.19 cells for 24 and 48 h. (a) Total (ERK1/2) and phosphorylated (p-ERK1/2) protein expression levels. Expression levels were normalized by GAPDH; (b) Ratio of p-ERK1/2/ERK1/2. Expression levels were normalized by GAPDH first. Each bar is indicated as the relative percentage of control cells at 24 and 48 h. The results are represented as the means ± SEM of three independent experiments. ** p < 0.01, compared with the control cells.
