Expression of Caspase-3 protein in sperm. Administration of C. borivilianum root extract at 250 and 500 mg/kg/day or glibenclamide to diabetic rats resulted in lower expression of caspase-3 protein as compared to non-treated diabetic rats. 250C: 250 mg/kg/day C. borivilianum root extract; 500C: 500 mg/kg/day C. borivilianum root extract, 600G: 600 μg/kg/day glibenclamide. n = 4 bands per treatment group, *p < 0.05 as compared to normal, non-diabetic control rats, †p < 0.05 as compared to non-treated diabetic rats. MW of caspase-3 is 32 kDa and β-actin is 43 kDa.
