Matrix metalloproteinases (MMPs), especially MMP-2 and MMP-9, play a significant role in the degradation of proteins and angiogenesis; while epidermal growth factor receptor (EGFR) is involved in the recovery of damaged tissues. Herein, we investigated the relationship between MMP-2 and MMP-9 / EGFR in the kidney tissues of streptozotocin-induced Wistar male rats. We also examined the effects of resveratrol known as a strong tissue-protective on these changes. Diabetes was induced by streptozotocin (55 mg/kg) and trans-resveratrol (20 mg/kg/day intraperitoneal) was used for treatment. Rats were divided into 4 groups as control, resveratrol (Res), diabetes (Diab) and diabetes plus resveratrol (Diab+Res). Superoxide dismutase (SOD) and catalase (CAT) levels were significantly decreased in the kidneys in the diabetic group, whereas nitrite / nitrate, urea, creatine kinase (CK) and uric acid concentrations increased. MMP-2, MMP-9, calcium-binding protein B (S100B) and platelet-derived growth factor (PDGF) concentrations of kidney were increased although reduced EGFR in the diabetes group. Resveratrol supplementation markedly restored all these structures. Diabetes activates MMP related inflammation and oxidative stress by suppressing antioxidant enzymes in the kidney tissues. Resveratrol has partly modulatory effects on diabetes-induced changes.}, number={2}
