TBI induces autophagy and the activation of GSK-3β in rat brains. (a) Immunoblotting analysis of GSK-3β as a function of time after TBI. Rat brains were removed after a specified time. Protein was extracted and analyzed using immunoblotting with anti-LC3, anti-p-ser9-GSK-3β, anti-p- tyr216-GSK-3β, anti-t-GSK-3β, and anti-GAPDH antibodies. GAPDH and t-GSK-3β were used as internal controls to normalize the amount of proteins. (b–d) The statistical results are presented as mean±S.E.M. (n=3/group). *P<0.05, **P<0.01 versus the respective control, one-way ANOVA
