Vitamin B receptor and its protective role in diabetic nephropathy

Objective To review the advances of studies on vitamin D receptor and its role in the pathogenesis of diabetic nephropathy. Data sources A comprehensive search of the Pub Med literatures without restriction on the publication date was carried out using keywords such as vitamin D receptor and diabetic nephropathy. Study selection Articles related to vitamin D receptor and diabetic nephropathy were selected and carefully analyzed. Results The ligands as well as construction and tissue distribution of vitamin D receptor were summarized. Pathogenesis of diabetic nephropathy was analyzed. The mechanisms underlying the renoprotective role of vitamin D receptor including inhibition of renin-angiotensin system, anti-inflammation, anti-fibrosis and the reduction of proteinuria were reviewed. Mounting evidences from animal and clinical studies have suggested that vitamin D therapy has beneficial effects on the renal systems and the underlying renoprotective mechanisms of the vitamin D receptor-mediated signaling pathways is a hot research topic. Conclusion Our study suggests that vitamin D receptor has a great potential for preventing the progression of diabetic nephropathy via multiple mechanisms.
