Abstract:
Objective To investigate the effects of the HyTK gene transduction on murine bladder carcinoma cells in vitro . Methods The retroviral vector plasmid PL(HyTK)SN was transfected into packaging cell line PA317 using the liposome method. The obtained recombinant retroviral supernatant fluid was used to infect murine bladder cancer cell line T739 cells. B resistant colonies, named as T739 TK, were obtained after hygromycin B selection. The integration and expression of HyTK gene in T739 TK cells were identified by RT PCR. The in vitro killing effects of GCV on T739 TK cells were observed. Results RT PCR showed that HyTK gene was inserted into T739 cells successfully and there was mRNA expression of HyTK gene. In vitro , T739 TK cells expressed the killing effects after treatment with GCV of different concentrations. However, T739 cells grew well at different doses of GCV. Conclusion GCV has obvious killing effect on HyTK gene transfected T739 cells in vitro .
