Chronic Exposure to NaBu Causes Resistance to Butyrate-Induced Cell Death. HCT116-PT and HCT116-BR cells were treated with 0–10 mM NaBu for 48 h (B). Cell viability was evaluated using the MTT reduction assay and presented as a percentage of the control. The values are mean ± S.D. (n = 3). *p < 0.05 **p < 0.01 indicate significant differences compared with the untreated control. #p < 0.05 indicates a significant difference in cell viability between the two cell types
