 note = {PMID:27033449, Persistent high concentration of glucose causes cellular stress and damage in diabetes via derangement of gene expressions. We previously reported high glucose activates hypoxia-inducible factor-1αand downstream gene expression in mesangial cells, leading to an extracellular matrix expansion in the glomeruli. A glucose-responsive transcription factor carbohydrate response element-binding protein (ChREBP) is a key mediator for such perturbation of gene regulation. To provide insight into glucose-mediated gene regulation in mesangial cells, we performed chromatin immunoprecipitation followed byDNAmicroarray analysis and identified platelet-derived growth factor-C (PDGF-C) as a novel target gene of ChREBP In streptozotocin-induced diabetic mice, glomerular cells showed a significant increase inPDGF-C expression; the ratio ofPDGF-C-positive cells to the total number glomerular cells demonstrated more than threefold increase when compared with control animals. In cultured human mesangial cells, high glucose enhanced expression ofPDGF-C protein by 1.9-fold. Knock-down of ChREBPabrogated this induction response. UpregulatedPDGF-C contributed to the production of typeIVand typeVIcollagen, possibly via an autocrine mechanism. Interestingly, urinaryPDGF-C levels in diabetic model mice were significantly elevated in a fashion similar to urinary albumin. Taken together, we hypothesize that a high glucose-mediated induction ofPDGF-C via ChREBPin mesangial cells contributes to the development of glomerular mesangial expansion in diabetes, which may provide a platform for novel predictive and therapeutic strategies for diabetic nephropathy., application/pdf, application/pdf},
