Hesperidin has been reported to have an excellent and wide variety of biological activities. This property has brought the compound to a new stage in the treatment of various oxidative stress-mediated diseases. The present investigation was aimed to evaluate the therapeutic potential of hesperidin by assaying the activities of antioxidant enzymes, lipid peroxidation, membrane bound marker enzymes, adenosine triphosphates, and TCA cycle enzymes, especially in kidney tissues during 7,12-dimethybenz(a)anthracene-induced breast cancer. Daily oral administration of hesperidin (30 mg/kg body wt) to breast cancer-bearing rats for 45 days demonstrated a significant (P < .05) decline in renal lipid peroxidation and membrane bound marker enzymes, as well as a remarkable increase in adenosine triphosphatases, mitochondrial functional enzymes, and renal antioxidants. Furthermore, histological studies of liver and kidney provided evidence of biochemical alterations. Thus, the protective effects of hesperidin on attenuating the peroxidation reaction and membrane bound marker enzyme activities as well as upregulation of adenosine triphosphatases, TCA cycle enzymes, and antioxidants suggest promising uses of flavonoglycoside hesperidin in the future treatment of oxidative stress-mediated diseases.
