FN1 and diabetes mellitus: Cheng et al. [40] found that the whole-body exposure of type 1 diabetic mice (DM) to 25 mGy X-rays weekly decreased the microalbuminuria, the renal accumulation of 3-nitrotyrosine and 4-hydroxynonenal, and the renal expression of collagen IV and fibronectin, suggesting that low-dose radiation (LDR) improved DM-induced oxidative/nitrosative damage and renal fibrosis effectively.
