a Analysis of protein expression by western blot. B4G12 cells were transfected with the same amount of Flag-tagged PAX6 WT or PAX6 K53/89R plasmid. Cell lysates were proved with anti-Flag and anti-GAPDH antibodies. b Relative expression levels of PAX6 were calculated. Note: de-SUMOylation induced the increased PAX6 protein level. c B4G12 cells were transfected with either PAX6 WT or PAX6 K53/89R plasmid, and then treated with 20 μg/ml CHX for 0, 12, or 24 h as indicated inhibiting protein synthesis. Cell lysates were analyzed by western blot using anti-Flag and anti-GAPDH antibodies. d The ratio of PAX6 protein was compared. Error bars showed means ± SEM (n = 3/group; *p < 0.05).
