Distinct effects of butyrate on colon cancer cell lines (A) HCT116, (B) HT-29, (C) Caco-2 cell growth curves for 24, 48, and 72 h, (D) data for cell growth curve (A–C). The “N/D” stands for “not detectable”. Letters that are not shared between concentration group means are significantly different by row within cell lines using Tukey’s HSD after on-way ANOVA, p < 0.05, at a given time point, cell growth curves were repeated (n = 4) for each cell line, and data are presented as means ± SDs.
