Urtica Dioica and Lamium Album Decrease Glycogen Synthase Kinase-3 beta and Increase K-Ras in Diabetic Rats

Area of Science:

• Biochemistry
• Pharmacology
• Diabetology

Background:

• Diabetes mellitus is a complex metabolic disorder characterized by hyperglycemia.
• Key signaling pathways involving K-Ras and GSK-3 beta play a role in glucose homeostasis.
• Natural compounds are being explored for their potential anti-diabetic effects.

Purpose of the Study:

• To evaluate the impact of Urtica Dioica and Lamium Album extracts on serum levels of K-Ras and GSK-3 beta in streptozotocin-induced diabetic rats.
• To assess the efficacy of these herbal extracts in modulating key molecular targets associated with diabetes.

Main Methods:

• A study involving 32 male Wistar rats, randomly assigned to control and diabetic groups.
• Diabetes was induced using streptozotocin (60 mg/kg).
• Treated groups received hydroalcoholic extracts of U. dioica or L. Album (100 mg/kg) daily for 28 days, with measurements of body weight, fasting blood sugar, blood glucose, K-Ras, and GSK-3 beta.

Main Results:

• Diabetic rats exhibited increased GSK-3 beta and decreased K-Ras levels compared to controls.
• Both U. dioica and L. Album extracts significantly reduced blood glucose levels.
• U. dioica extract significantly reduced GSK-3 beta levels, while both extracts increased K-Ras levels in diabetic rats.
• No significant differences were observed between the two extracts regarding their effects on blood glucose and K-Ras levels.

Conclusions:

• Urtica Dioica and Lamium Album extracts demonstrate potential in improving blood glucose levels in diabetic rats.
• These effects appear to be mediated through the regulation of GSK-3 beta and K-Ras pathways.
• Further research is warranted to fully elucidate the therapeutic potential and mechanisms of these herbs in diabetes management.
