Anti-laryngeal carcinoma with adenovirus vector mediated HSV-tk gene
Abstract：Objective To observe killing action of HSV-tk/GCV system onlaryngeal cancer cells. Methods Hep-2 cells were transfected by adenovirus vector with LacZ gene, then stained with X-gal for measurement of the adenovirus transfected efficiency. The recombinant adenovirus carrying HSV-tk was constructed by homologous recombination techniques. Hep-2 cells survival and by stander effect were observed after adding 10 mg/L GCV to transfected cells. Results The more the multiplicity of infection (MOI), the more the adenovirus transfected efficiency to Hep-2 cells. 100% transfected efficiency needs MOI 200. The killing action of HSV-tk/GCV on Hep-2 cells depends on the amount of AdCMVtk. There is a weak by stander effect. Conclusion Adenovirus mediated HSV-tk/GCV can kill Hep-2 cells.
