Expression of hepatocyte growth factor receptor in flbroblasts induced by high glucose / 中华肾脏病杂志

ABSTRACT

Objective To examine the expression of hepatocyte growth factor(HGF) receptor (c-met) and investigate the changes in activity of the HGF/c-met system in human kidney fibroblast by high glucose. Methods HGF and c-met mRNA levels in fibroblast induced by high glucose were detected by RT-PCR. C-met protein was examined by Western blotting. At the same time, the expression of TGF-? and c-met in the exogenous HGF and treating with anti-c-met antibody in vitro were measured. Results Extremely rapid induction of HGF and c-met mRNA was observed at the first six hours by high glucose. On the other hand, both c-met mRNA and c-met protein were markedly increased. HGF (50 ng/ml) induced the expression of c-met ( P
