Abstract:
Objective: To construct an eukaryotic expression plasmid containing gene coding for the hemagglutinin neuraminidase(HN) of Newcastle disease virus (NDV), and to study its mechanism and value in antitumor therapy. Methods: The HN cDNA was abtained from NDV with RT PCR and an eukaryotic expression vector of HN gene ( pcDNA3 HN ) was constructed. The antitumor effect was evaluated after injecting pcDNA3 HN into mice bearing B16 melanoma. Results: The HN cDNA of NDV was successfully cloned and pcDNA3 HN had a good expression in COS 7 cells. Animal experiments suggested that the pcDNA3 HN could significantly increase CTL and NK activity of tumor bearing mice. Conclusion:The eukaryotic expression plasmid containing the gene coding for the (HN) has the function of increasing CTL and NK activity of tumor bearing mice.
