title: Modulating effects of hesperidin on key carbohydrate-metabolizing enzymes, lipid profile, and membrane-bound adenosine triphosphatases against 7,12-dimethylbenz(a)anthracene-induced breast carcinogenesis.
abstract: The aim of this study was to document the effect of hesperidin on the key enzyme activities of carbohydrate metabolism, lipid profile, and membrane-bound adenosine triphosphatases (ATPases) during 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast carcinogenesis. Hesperidin has been reported to have multiple biological properties. Breast cancer was induced by single dose of DMBA (20 mg/kg body weight (bw)). The results revealed that there was a significant increase in the activities of hexokinase, phosphoglucoisomerase, and aldolase and a concomitant decrease in the activities of glucose-6-phosphatase and fructose-1,6-diphosphatase in cancer-induced animals. The activities of ATPases were found to be decreased both in erythrocyte membrane and in the liver of mammary cancer-bearing animals. The lipid profiles such as total cholesterol, free cholesterol, phospholipids, triglycerides, and free fatty acids significantly increased and in contrast the ester cholesterol in plasma was found to be decreased, whereas it was found to be elevated in the liver of cancer-bearing groups. The altered levels of the above-mentioned biochemical parameters in cancer-bearing animals were significantly ameliorated by the administration of hesperidin at the dosage of 30 mg/kg bw for 45 days. The histopathological analysis of breast and liver tissues were well supported the modulatory property of hesperidin, and this might be associated with normalizing the gluconeogenesis process, stabilization of cell membranes, and modulation of lipid biosynthesis.
