Modulatory Role of Shorea robusta Bark on Glucose-metabolizing Enzymes in Diethylnitrosamine Induced Hepatocellular Carcinoma in Rats

Introduction: The modulations of glucose‑metabolizing enzyme activities play a vital rolein the depletion of energy metabolism and leads to inhibition of cancer growth. Objective: To find the effect of shorearobusta bark extract on glucose-metbolizing enzymes in diethylnitrosamine (DEN) induced hepatocellular carcinoma rats. Materials and Methods: Biochemical evaluation of glucose metabolizing enzyme were done in before and after shorearobusta bark extract (500mg/kg) treatment in DEN induced rats. Results: A significant increasein the activities of the key glycolytic enzymes viz., hexokinase and phosphoglucoisomerase, with a significant decrease in the gluconeogenic enzymes glucose‑6‑phosphatase and fructose‑1,6‑bisphosphatasewere observed in HCC bearing rats, when compared with the control. Administration of shorearobusta extract caused a significant decrease in theactivities of glycolytic enzymes and an increase in the gluconeogenic enzymes activities to near normal values. Conclusion: The current findings suggest that the S. robusta extract has a definite modulating role on the key enzymes ofglucose‑metabolism in HCC. The modulatory effect may be due to the phytoactive constituents present in the extract of S. robusta.
