Effects of vitamin C on expression of 14-3-3 isoforms in AGS cells. Cells were treated with vitamin C (0 and 300 lg/ml) for 24 h. The cell lysates were subjected to SDS–PAGE and analyzed by Western blotting. Densitometric analyses of data were expressed as the mean ± SD of three independent experiments (*P < 0.05, **P < 0.01 compared with control).
