title: Concomitant expression of hepatocyte growth factor (HGF), HGF activator and c-met genes in human glioma cells in vitro.
abstract: Three new cell lines of human glioblastoma have been established. These cells co-expressed hepatocyte growth factor (HGF) and its receptor, c-Met, genes in vitro. Reverse-transcriptase/polymerase-chain reaction study revealed that the cells also expressed gene for HGF activator, a recently cloned serine proteinase, suggesting that HGF might have a role in glioma cells in vitro as an autocrine factor. The activator mRNA was also detected in other well-established glioma cell lines, glioma tissues and normal brain. The concomitant expression of HGF, HGF activator and c-met was also detected in one glioblastoma case in vivo out of five tested.
