Effects of bacterial metabolites on KLF4 protein in HT29-MTX cells. Representative Western blot and densitometric analyses of KLF4 and P21 proteins in HT29-MTX cells incubated with (A) 0, 10, 20 mM acetate, (B) 0, 5, 10 mM propionate, and (C) 0, 1, 5 mM butyrate. Each graph reports means of three independent experiments with three internal repeats per experiment. Means with different letters are significantly different (P-value <0.05).
