Butyrate and propionate inhibited IL-6 in LPS and TNFα-stimulated HUVEC. Pre-treatment with butyrate (0.1 mM) and propionate (0.3 mM) for 24 h significantly reduced IL-6 levels in 12 h LPS- or TNFα-stimulated groups. (A) and (B) show the effects of butyrate; (C) and (D) show the role of GLPG and/or SHB on the effects of propionate; N = 4, ∗∗p < 0.01, ∗∗∗p < 0.001 compared with control group; ##p < 0.01, ###p < 0.001 compared with LPS or TNFα group; $p < 0.05, $$p < 0.01, $$$p < 0.001 compared with butyrate or propionate alone group.
