- BBR ameliorated the biochemical symptoms and renal pathophysiology in DN rats.
- The DN mechanism was associated with the regulation of AGEs-RAGE signaling pathway.
- BBR effectively disrupted the AGEs-RAGE axis and downstream processes.
In this study, we explored the effect of berberine treatment on the AGEs-RAGE pathway in a rat model of diabetic nephropathy, and we investigated the mechanism by which key factors caused kidney injury and the effects of berberine. In vivo, berberine improved fasting blood glucose, body weight, the majority of biochemical and renal function parameters and histopathological changes in the diabetic kidney. Western blotting and immunohistochemistry revealed significant increases in the levels of AGEs, RAGE, P-PKC-β and TGF-β1 in injured kidneys, and these levels were markedly decreased by treatment with berberine. In vitro, berberine inhibited mesangial cell proliferation. Cells treated with berberine showed reduced levels of AGEs, accompanied by decreased RAGE, p-PKC and TGF-β1 levels soon afterwards. Berberine exhibited renoprotective effects in diabetic nephropathy rats, and the molecular mechanism was associated with changes in the levels and regulation of the AGEs-RAGE-PKC-β-TGF-β1 signaling pathway.
