Expression levels of Bcl-2, Bax, caspase-3 and caspase-9 proteins in the DRG. (A) The expression level of Bcl-2 protein in rat bladders was detected by western blot analysis. (B) The expression levels of Bax, caspase-3, cleaved caspase-3, caspase-9 and cleaved caspase-9 proteins in rat bladders were detected by western blot analysis. *P<0.05 vs. control group; #P<0.05 vs. caffeine group; @P<0.05 vs. DM group. Bcl-2, B-cell lymphoma-2; Bax, Bcl-2-associated X protein; DRG, dorsal root ganglion; DM, diabetes mellitus.
