PG - 461-467 LID - 10.1080/13813455.2018.1423624 [doi] AB - OBJECTIVE: We hypothesised that vitamin D has a beneficial renal protective effect from diabetic nephropathy (DN). METHODS: Four rat groups were included: normal control (control), type 2 diabetes for eight weeks (DM), treated group with angiotensin receptor blocker losartan (DM + L), and vitamin D-treated group started from the onset of diabetes (DM + Vit D). RESULTS: In the both treated groups, we found a significant (p < .05) reduction in the renal pro-inflammatory and profibrotic markers induced by diabetes. Vitamin D caused more reduction in monocyte chemoattractant protein-1 (MCP-1), transforming growth factor (TGFbeta-1), and renin-angiotensin levels that gave better kidney function compared to the DM + L group. CONCLUSION: Vitamin D may have a valuable role in the renal protective effect from DN, this may occur via expression of its VDR, Klotho and blocking renin-angiotensin activation, so vitamin D should be considered as a target in renal prophylactic measures against DN.
