Hepatocyte growth factor receptor in acute tubular necrosis.

In acute tubular necrosis, there are early transient increases in circulating and local bioactive hepatocyte growth factor (HGF) levels and renal HGF receptor (c-MET) gene expression. It has therefore been suggested that endogenous HGF may play a role in initiating renal repair. To test this hypothesis, changes in the levels, activity, and anatomic distribution of c-MET protein were characterized in relation to the onset and localization of DNA synthesis in kidneys of rats with ischemia-induced acute tubular necrosis.
