HGF and BMP-7 ameliorate high glucose-induced epithelial-to-mesenchymal transition of peritoneal mesothelium.

Abstract\nOver time, peritoneal dialysis results in functional and geomorphologic alterations of the peritoneal membrane, but the central mechanisms and whether these changes be reversible argon not completely understood. Here, we canvas the effects of utmost levels of glucose, which are engraft in the dialysate, on human peritoneal mesothelial cells (HPMCs). We found that luxuriously concentrations of glucose induced epithelial-to-mesenchymal renewal (EMT) of HPMC, suggested by decrease sort of E-cadherin and increased expression of alpha-smooth vigour actin, fibronectin, and type I collagen and by increased cell migration. calibration of glucose concentration on twenty-four hours 2 reversed the phenotypical transformation, but the changes were irreversible by and by 7 d of input with high glucose. In addition, pic of HPMC to high glucose resulted in a decreased expression of the antifibrotic cytokines, hepatocyte ripening factor (HGF) and bone morphogenic protein 7 (BMP-7). Exogenous treatment with HGF resulted in a dosage-dependent prevention of high glucose-induced EMT. Both BMP-7 peptide and gene transfection with an adenoviral transmitter of BMP-7 also protected HPMCs from EMT. Furthermore, adenoviral BMP-7 transfection decreased peritoneal EMT and ameliorated peritoneal alter in an animal shape of peritoneal dialysis. In summary, high concentrations of glucose induce a reversible EMT of HPMCs, associated with decreased production of HGF and BMP-7. preaching of HPMCs with HGF or BMP-7 blocks high glucose-induced EMT, and BMP-7 ameliorates peritonealfibrosis in an animal model of peritoneal dialysis.If you want to get a full essay, order it on our website:
