Objective:
To investigate the biological effect of hepatocyte growth factor (HGF) on HGF gene-transfected Raji cells.
Methods:
Total RNA was extracted from human hepatic tissue, HGF gene cDNA was amplified by RT-PCR, and then cloned into vector pVITRO2-mcs to construct recombinant eukaryotic expression vector pVITRO2-mcs-HGF. The recombinant vector was transfected to Raji cells, and the stably transfected cells were selected by homomycin B in serial passages, and confirmed by real-time fluorescent quantitative PCR, ELISA, immunocytohistochemistry. The biological features of transfected Raji cells were evaluated by semisolid culture.
Results:
RT-PCR results showed that Raji cells were transfected successfully with recombinant eukaryotic expression vector pVITRO2-mcs-HGF. HGF mRNA and protein were expressed successfully in Raji cells. Expression of HGF gene enhanced proliferation, metastasis and invasion of Raji cells.
Conclusion:
HGF gene has been cloned and recombined to construct recombinant eukaryotic expression vector pVITRO2-mcs-HGF successfully. Transfected HGF may change the biological features of Raji cells.
