| Research Abstract |
Background : To investigate the behavior of nuclear proteins in apoptosis induced by protein phosphatase 1 inhibitors, okadaic acid, anti-cancer drugs, and UV radiation in cultured human oral cancer cells.
Methods : Dynamic alternations of nucleolin and AgNOR proteins in all inducer-induced apoptosis of cultured human oral cancer cells and in a cell-free apoptotic system were examined using Western blot analysis and immunocytochemical method.
Results: The 110-kD_a form of nucleolin and AgNOR protein decreased and the 80-, and 95-kD_a forms appeared during apoptosis in human oral cancer cells and in a cell-free apoptotic system. In addition, the induction of DNA ladder formation coincided with the appearance of alternation of nucleolin and AgNOR proteins in a cell-free apoptosis. Nucleolin diffusely spread out into the nuclear material in the apoptotic body of human oral cancer cells.
Conclusions : The present results indicate that alternations of nucleolin and AgNOR proteins are associated with the induction of DNA fragmentation and the final active phase of apoptosis induced by okadaic acid-, anti-cancer drugs, UV radioation in oral cancer cells.
