Overview

Controlled animal study demonstrates that metformin restores aortic endothelial function in diabetic rats, supporting its protective cardiovascular role in type 2 diabetes.

Key Points

To determine whether metformin alleviates impaired endothelial function, oxidative stress, inflammation, and advanced glycation end products in a nonobese rat model of type 2 diabetes.
Goto-Kakizaki nonobese diabetic rats were maintained on a normal or high-fat diet for 4 months and administered metformin during the final 4 weeks.
Aortic rings were harvested to quantify endothelium-dependent vasodilatation, vascular and systemic oxidative stress, nitric oxide bioavailability, glycation markers, and chemokine CCL2 levels.
High-fat diet-fed diabetic rats exhibited hyperlipidaemia, heightened systemic and vascular oxidative stress, and significant impairment in endothelium-dependent vasodilation.
Metformin treatment normalized aortic endothelial function and significantly improved nitric oxide bioavailability, oxidative stress, glycation, CCL2 concentrations, and insulin resistance.
