Abstract:
To determine the effect of Ad-53 and Ad-16both alone and in combination on the growth of human lung adeuocarcinoma cell line GLC-82. Methods: Human lung adenocarcinoma cell line GLC-82 were trasferredvia an adenovirus-mediated p53 gene (Ad-p53), P16 gene Ad-p16 or both. Cell growth inhibition assay, colony formation, flow cytometry assay, TUNEL, RT-PCR and immunhistochemistry assays were used to evaluate the therapeutic efficiency of such strategy on trasferred cells. Results: in vitro experiments, at the same dose ofAd (multiplicity of infection), simultaneous transfer of Ad-p53 and Ad-p16 to GLC-82 cells caused stronger therapeutic efficacy than caused by single kind of Ad transfer, demonstrating that Ad-p53 treatment has synergistic efficacy with Ad-p16 treatment on GLC-82 cells. Conclusion: Ad-p53 for GLC-82 cells shows enhanced therapeutic efficiency when combined with Ad-p16.
