The Effects of Urtica dioica and Lamium album Extracts on the Expression Level of Cyclooxygenase-2 and Caspase-3 in the Liver and Kidney of Streptozotocin-Induced Diabetic Rats
Background: Diabetes seems to be associated with increased inflammation and induced apoptosis in several tissues. Urtica dioica and Lamium album have shown to possess a variety of beneficial properties like anti-inflammatory effects. In this experimental study, we tried to evaluate the effects of U....

| Summary: | Background: Diabetes seems to be associated with increased inflammation and induced apoptosis in several tissues. Urtica dioica and Lamium album have shown to possess a variety of beneficial properties like anti-inflammatory effects. In this experimental study, we tried to evaluate the effects of U. dioica and L. album extracts on the expression level of cyclooxygenase-2 (COX-2; as an inflammation marker) and caspase-3 (CASP-3; as an apoptotic marker) in the liver and kidney tissues of diabetic rats. Methods: Thirty-two male Wistar rats were randomly allocated to four groups: normal control, diabetic control, diabetic treated with U. dioica (100 mg/kg/daily), and diabetic treated with L. album (100 mg/kg/daily) for 28 days. At the end of the study, liver and kidney tissues were harvested and mRNA expression level of COX-2 and CASP-3 was determined by real-time PCR technique. Also, serum glucose was measured. Results: Liver COX-2 mRNA in diabetic rats was significantly higher than normal control rats (P=0.02). However, U. dioica and L. album caused significant decrease in mRNA expression of liver COX-2 in diabetic rats (P=0.015 and P=0.03, respectively). Also, in diabetic rats treated with both extracts, serum glucose was remarkably lower than diabetic control rats (P<0.0001 and P<0.01, respectively). Conclusion: It appears that U. dioica and L. album might decrease liver damage by decreasing the inflammatory effects of COX-2 in streptozocin-induced diabetic rats. Since these plant extracts may influence diabetes by several mechanisms, further research in this field is warranted. |
