Effect of quercetin on migration of Caco-2 cells. (a) Cells were incubated in 24 well plates and treated with quercetin (5 μM) for 24 h in the presence or absence of anti-toll-like receptor 4 antibody (2 μg) or pyrrolidine dithiocarbamate (1 μM). a’: Blank control; b’: Quercetin of 5 μM; c’: Anti-toll-like receptor 4 antibody (2 μg); d’: Pyrrolidine dithiocarbamate (1 μM); e’: Quercetin (5 μM) + anti-toll-like receptor 4 antibody (2 μg); f’: Quercetin (5 μM) + pyrrolidine dithiocarbamate (1 μM). (b) The closure rate of cells was recorded, and the data were obtained from triplicate experiments and expressed as the means ± standard deviation (n = 3). *P < 0.05, **P < 0.01, versus blank control; #P < 0.05, quercetin (5 μM) + anti-toll-like receptor 4 versus anti-toll-like receptor 4 alone; ^&P < 0.05, quercetin (5 μM) + pyrrolidine dithiocarbamate versus pyrrolidine dithiocarbamate alone
