摘要
Diabetic nephropathy (DN) is one of the most important complications of diabetes mellitus and it is considered as a principal cause for end-stage renal failure. Ganoderma lucidum (GL) has been studied for its reno-protective effect against different kidney injury models. The aim of our study is to investigate the mechanisms by which GL can improve kidney injury and consequent renal inflammation and fibrosis.GL either in a low dose (250 mg/kg, i.p.) or high dose (500 mg/kg, i.p.) was administered to DN rat model, and nephropathy indices were investigated.GL treatment significantly down-regulated kidney injury molecule-1 (KIM-1) gene expression and inhibited TLR-4 (Toll-like receptor-4)/NFκB (nuclear factor kappa B) signalling pathway. As well, GL treatment significantly decreased the pro-inflammatory mediator; IL-1β (interleukin-1 beta) level and fibrosis-associated growth factors; FGF-23 (fibroblast growth factor-23) and TGFβ-1 (transforming growth factor beta-1) levels. In addition, GL remarkably inhibited (Bax) the pro-apoptotic protein and induced (Bcl-2) the anti-apoptotic protein expression in kidneys. Moreover, GL treatment significantly alleviates kidney injury indicated by correcting the deteriorated kidney function and improving oxidative stress status in DN rats.GL significantly improved renal function indices through dose-dependent kidney function restoration, oxidative stress reduction, down-regulation of gene expression of KIM-1 and TLR4/NFκB signalling pathway blockage with subsequent alleviation of renal inflammation and fibrosis.
