| ABSTRACT: OBJECTIVE To investigate whether Raddeanin A (RA) affects the growth and migration of oral cancer CAL27 cells through regulating apoptosis and EMT. METHODS Human oral cancer CAL27 cells in logarithmic growth phase were selected and grouped according to the experiment. CCK-8 assay was used to detect the effects of RA on cell proliferation, cell cloning assay to detect cell proliferation ability, Hoechst 33342 staining assay and flow cytometry to detect apoptosis of cells, and scratch assay to detect the migration of cells. Western blot was performed to detect the expression of apoptotic proteins B lymphoblastoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), Cleaved Caspase-3, and EMT-related proteins such as E-cadherin, N-cadherin, Vimentin and Snail. RESULTS CCK-8 and clonogenic assay showed the cell proliferation of the administered group was decreased in a concentration-dependent manner (P<0.05 versus the control); Hoechst 33342 staining assay and flow cytometry showed that RA induced apoptosis and inhibited the growth of CAL27 cells (P<0.05 versus the control); and the scratch assay showed that the migration of the cells was decreased (P<0.05 versus the control). Western blot showed that the expression of apoptotic protein Bcl-2 was significantly decreased, and the expression of Bax and Cleaved Caspase-3 significantly increased (P<0.05 versus the control; The expression of EMT-related protein E-cadherin was significantly increased, and the expression of N-cadherin, Vimentin and Snail significantly decreased (P<0.05 versus the control). CONCLUSION Raddeanin A can inhibit growth and migration of oral cancer CAL27 cells through regulating apoptosis and EMT. |
