Bottom Line: However, the effect of NDV on lung cancer has yet to be elucidated.Following rl-RVG transfection, RVG and NDV gene expression, decreased tumor growth, subcutaneous tumor necrosis, tumor apoptosis and an increased number of cluster of differentiation (CD)3(-)/CD49(+) natural killer cells were more evident in the rl-RVG group.The present study demonstrated that rl-RVG transfection effectively restrained lung adenocarcinoma A549 cell growth in vivo, which may have been accomplish by inducing tumor cell apoptosis and regulating the cell immune response.

ABSTRACT
Newcastle disease virus (NDV) has been reported to selectively duplicate in and then destroy tumor cells, whilst sparing normal cells. However, the effect of NDV on lung cancer has yet to be elucidated. In the present study, recombinant NDV (rl-RVG) was applied to lung adenocarcinoma A549 cell tumor-bearing mice to explore its effect on the proliferation of the cells and the immune response of the mice. Following rl-RVG transfection, RVG and NDV gene expression, decreased tumor growth, subcutaneous tumor necrosis, tumor apoptosis and an increased number of cluster of differentiation (CD)3(-)/CD49(+) natural killer cells were more evident in the rl-RVG group. The present study demonstrated that rl-RVG transfection effectively restrained lung adenocarcinoma A549 cell growth in vivo, which may have been accomplish by inducing tumor cell apoptosis and regulating the cell immune response.

Flow cytometry determined the number of NK cells in the spleen. The results proved that the number of NK cells was markedly higher in the rl-RVG and NDV groups compared with the PBS group (P<0.001), with the rl-RVG group exhibiting a higher number of cells than the NDV group. NK, natural killer; NDV, Newcastle disease virus; RVG, rabies virus glycoprotein; rl-RVG, recombinant NDV; PBS, phosphate-buffered saline; CD, cluster of differentiation; PE, phycoerythrin; FITC, fluorescein isothiocyanate.
