ABSTRACT
AIM:
To investigate the anti-tumor effect of newcastle disease virus (NDV).METHODS:
Plaque formation test was used to investigate the effect of NDV on chicken embryofibroblasts(CEF). Cell suppression test, agarose gel electrophoresis, cytoskeleton staining, fluorescence staining, TUNEL staining, and sialic acid content determination were used to observe the influence of NDV on several human tumor cells.RESULTS:
The Plaque formation was observed in chicken embryo fibroblasts.NDV could lead to the apparent cytopathy of BHK, Hela and Hep-2 tumor cells, but has no apparent effect on Wish cells. The strong suppressive effect of NDV on the growth of these tumor cells was found without dose dependence. The optimal dose of NDV could induce the death of tumor cells which was mainly apoptosis, as showed by the classical DNA ladder in DNA gel electrophoresis. NDV also resulted in the changes of cytoskeleton and decreased the level of sialic acid contents on tumor cells.CONCLUSION:
NDV may be a potential anti-tumor agent.
