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

Abstract\noer time, peritoneal dialysis results in operative and structural alterations of the peritoneal membrane, scarcely the underlying mechanisms and whether these changes are rechargeable are not entirely understood. Here, we studied the effects of broad(prenominal) levels of glucose, which are found in the dialysate, on human peritoneal mesothelial carrells (HPMCs). We found that towering concentrations of glucose constituentrate epithelial-to-mesenchymal transition (EMT) of HPMC, suggested by decrease formulation of E-cadherin and increased bearing of alpha-smooth muscle actin, fibronectin, and type I collagen and by increased cell migration. Normalization of glucose concentration on day 2 change by reversal the phenotypic transformation, but the changes were irreversible after 7 d of stimulation with high glucose. In addition, exposure of HPMC to high glucose resulted in a decreased expression of the antifibrotic cytokines, hepatocyte growth factor (HGF) and fig up morphogenic protein 7 (BMP-7). Exogenous intervention with HGF resulted in a dosage-dependent cake of high glucose-induced EMT. Both BMP-7 peptide and gene transfection with an adenoviral vector of BMP-7 also defend HPMCs from EMT. Furthermore, adenoviral BMP-7 transfection decreased peritoneal EMT and ameliorated peritoneal thickening in an wildcat perplex of peritoneal dialysis. In summary, high concentrations of glucose induce a reversible EMT of HPMCs, associated with decreased work of HGF and BMP-7. Treatment 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 take aim a full essay, put up it on our website:
