Punica granatum L. peel extract protects diabetic nephropathy by activating the Nrf-2/HO-1 pathway
Diabetes raises cardiovascular morbidity and mortality worldwide and causes retinopathy, neuropathy, and nephropathy. Punica granatum L. (Pomegranate) is a fruit that has been used for its medicinal properties in various cultures. This article aims to investigate the antioxidant, anti-inflammatory, anti-apoptotic activity of Punica granatum L. peel ethanol extract (PGE) and its efficacy on NF-κB and Nrf-2/HO-1 signaling pathways in kidney tissue of rats with streptozotocin-induced diabetes. Single dose STZ 60 mg/kg/i.p. rats were given to induce diabetes and blood glucose measurements were taken 7 days later. PGE 10 mg/kg/p.o. administered to the treatment groups for 20 days. Blood, kidney, and pancreas samples taken from anesthetized rats were analyzed biochemically and histopathologically. It was observed that STZ increased the levels of urea, uric acid and creatine in the blood, while PGE significantly decreased these parameters. The diabetic group had higher MDA and lower renal tissue GSH level, CAT, GPx, and SOD activity than the control group. STZ also enhanced inflammation, apoptosis, Bax, Caspase-3, and NF-κB expression, and decreased Bcl-2, HO-1, and Nrf-2 expression. Experimental results showed that PGE has the potential to alleviate the harmful effects on the kidney and pancreas by altering the mentioned parameters in diabetic rats.
期刊介绍：
Acta Diabetologica is a journal that publishes reports of experimental and clinical research on diabetes mellitus and related metabolic diseases. Original contributions on biochemical, physiological, pathophysiological and clinical aspects of research on diabetes and metabolic diseases are welcome. Reports are published in the form of original articles, short communications and letters to the editor. Invited reviews and editorials are also published. A Methodology forum, which publishes contributions on methodological aspects of diabetes in vivo and in vitro, is also available. The Editor-in-chief will be pleased to consider articles describing new techniques (e.g., new transplantation methods, metabolic models), of innovative importance in the field of diabetes/metabolism. Finally, workshop reports are also welcome in Acta Diabetologica.
