Western blot analysis of cleaved-caspase 3 in the dorsal portion of lumbar spinal cord. Values are presented as the mean ± SEM band density ratio for each group. Beta-actin (B-actin) was used as an internal control. Asterisks indicate significant difference (*P < 0.05, ***P < P < 0.01 and ***P < 0.001) vs. control group. Hashtags indicate significant difference (##P < 0.01) vs. diabetic groups
