Fig. 1From: Bacterial endotoxin decreased histone H3 acetylation of bovine mammary epithelial cells and the adverse effect was suppressed by sodium butyrateEffect of lipopolysaccharide (LPS) on histone H3 and H4 acetylation levels in MAC-T bovine mammary epithelial cells. The MAC-T bovine mammary epithelial cells were treated for 48 h with LPS at 0 (control), 1, 10, 100, 1000 endotoxin units (EU)/mL, respectively. (a) Histone H3 levels deceased significantly after LPS treatments (n = 5/treatment); (b) Histone H4 levels were not significantly (P > 0.05) affected by LPS treatments (n = 6/treatment). Data represent the mean and standard deviation and the asterisk indicates statistical difference between the indicated column and the control column (*, P < 0.05; **, P < 0.01). The raw data were shown in Additional file 1: Table S1Back to article page
