Effect of sodium butyrate (NaB) treatment for (A) 24 h and (B) 48 h on the apoptosis (including both early and late apoptosis) of cancerous HCT116 (solid lines) and non-cancerous NCM460 (dashed lines) colon cells. Values are means ± SD, n = 5 to 6. There was a significant interaction between cell type and concentration at 24 h (p < 0.0001) and at 48 h (p < 0.0001) by two-way ANOVA. * Different from HCT116 control (0 mmol/L NaB); * p < 0.05, ** p < 0.0001. + Different from NCM460 control (0 mmol/L NaB); + p < 0.05, ++ p < 0.0001.
