Influence of SFN on cell cycle progression/distribution in PA-1 cells: (A) Cell cycle analysis of PA-1 cells after being cultured with SFN for 24 h; (B) SFN induced an increase in the number of G 2 /M phase cells (%). The symbols * and & in each group of bars indicates that the differences resulting from treatment with SFN is statistically significant at P < 0.05.
