- Abstract
- Background: Hepatocyte growth factor (HGF) is a potent mitogenic cytokine. C-met protein, which is known to be the HGF receptor has transmembrane tyrosine kinase activity and is encoded by the c-met oncogene. The HGF/c-met signaling pathway may play various roles in the carcinogenesis of various organs. Methods: We examined HGF and c-met mRNA expression by utilizing reverse transcription polymerase chain reaction on 40 surgically resected intracranial meningiomas (25 benign, 10 atypical, and 5 anaplastic cases). Results: An HGF overexpression was detected in 28%, 50%, and 80% of the benign, atypical and anaplastic meningiomas, respectively; a high expression of HGF or the coexpression of HGF/c-met was detected in the high grade meningiomas (the atypical and anaplastic cases, p=0.046, p=0.014). An HGF expression was statistically significant in the recurrent meningiomas (p=0.003), and HGF expression was significantly lower than c-met mRNA expression in benign meningiomas (p=0.034). Conclusions: There was no correlation between histologic subtypes and HGF/c-met expression. Determination of HGF expression can be used as a molecular predictor for recurrence of meningioimas. These results suggest that HGF and c-met expression in meningiomas may be associated with anaplastic progression.
