Gene expression of HGF and c-met proto-oncogene was examined during rat brain development and in cultured PC-12 cells, using reverse-transcriptase (RT)-polymerase chain reaction (PCR) technique. The both mRNAs of HGF and c-met proto-oncogene were remained at low levels in the middle and late stages of gestation (E-13 and E-18). After birth, and the level of both mRNA expression suddenly increased. During P-1 and P-12, their high level of expression continued and then decreased in P-20 and adult brain. Both HGF mRNA and c-met photo-oncogene mRNA were transiently expressed between day 2 and day 5, and disappeared in cultured PC-12 cells treated with NGF. The neurites of PC-12 cells that were treated with anti-sense oligonucleotides of HGF and c-met proto-oncogene, were shorter and fewer in number than untreated control cells. We conclude that neurite extension of PC-12 cells treated with NGF may ensue by way of c-MET protein activation and signal transduction pathways. Thus, c-MET protein activation and up-regulation of the two mRNAs may also play an important role in neuronal maturation in the developing rat brain.
