Fig. 6. Protein expression in the urethra and cyclic guanosine mono-phosphate (cGMP) levels in the corpus cavernosum. (A) All groups were com-pared with respect to p-AKT, AKT, Bax, Cleaved PARP, and Bcl-2 expression in the corpus cavernosum by western blotting. (B) Relative density of bands in the western blot analysis for each group. *P<0.05 p-AKT/AKT compared with the Old group, **P<0.05. Cleaved PARP/PARP compared with the Old group, #P<0.05 Bax compared with the old group, ##P<0.05 Bcl-2 compared with the old group. (C) cGMP levels in the corpus cavernosum. Each bar shows the mean values. *P<0.05 compared with the old group.
