Butyrate stimulates IL-32α expression in human intestinal epithelial cell lines

Figure 6 Effects of butyrate on histone H3 acetylation. HT-29 cells were stimulated for 12 h with IL-1β (50 ng/mL) in the presence or absence of butyrate (10 mmol/L). Histone H3 acetylation was then detected by histone H3 acetylation assay kits (Epigentek; Brooklyn, NY, USA). Histone H3 acetylation was expressed as a value relative to medium alone. The data are expressed as mean ± SD (n = 4). ^aP < 0.05, ^bP < 0.01.
