[Expression of HGF and its receptor c-Met in renal cell carcinoma].
OBJECTIVE
To study the clinical significance of expression of hepatic growth factor (HGF) and its receptor c-Met in renal cell cancer (RCC).


METHODS
Twenty-six patients with RCC and 10 benign renal tumor patients were examined. The expression of HGF and c-Met mRNA was detected using Northern blot. GAPDH was used as the internal control.


RESULTS
Twenty-one out of 26 patients with RCC had positive gene expression of HGF and c-Met with the positive rate of 80.8%. According to the tumor TNM staging, the more advanced the cancer had a stronger expression of HGF and c-Met, the expression of c-Met was higher than that of HGF in the RCC. Whereas in the control group with benign tumor, the expression of c-Met was rather mild.


CONCLUSIONS
The result suggests that HGF and its receptor c-Met may play an important role in the development and progression of renal cancer, which may also imply a potential clinical significance in diagnosing and assessing prognosis of RCC.
