Abstract:
Objective To construct an expression vector harboring CYP2B1 suicide gene, and detect its expressions in tumor cell lines. Methods PCR amplification was performed using primers based on murine CYP2B1 gene sequence from gene bank and pc3/2B1 as template. PCR product was directly inserted an eukaryotic expression plasmid pcDNA3.0. The recombinants were analyzed and identified by restriction enzyme analysis, PCR and sequencing. Then the recombinant vector pcDNA3.0/CYP2B1 was transfected into three tumor cell lines by liposome-mediated method. The expressions of CYP2B1 gene in all the cell lines were detected by RT-PCR method. Results pCDNA3.0/CYP2B1 vector was successfully constructed, and could express CYP2B1 mRNA in the three tumor cell lines. Conclusion Eukaryotic expression vector pcDNA3.0/CYP2B1 containing CYP2B1 gene under the control of a CMV promoter is an novel effective expression vector for tumor gene therapy.
