Cell viability assay: (A) HT-29, SW48, and Caco-2 were treated with various concentrations of melatonin for 72 h. (B–D) HT-29, SW48, and Caco-2 were treated with various concentrations of melatonin alone or together with 0.1 mM TUDCA or with 1 mM TUDCA. Means ± standard error of mean (SEM) of three separate experiments are shown. Two-way analysis of variance (ANOVA), followed by Dunnett’s post hoc test, was performed to compare each treatment group and control; statistically significantly different from control: *, p < 0.05; #, p < 0.01.
