Fig. 5: Effects of siRNA targetting ERK1(siERK1) and ERK2 (siERK2) on low dose (0.1 μg/mL) LPS induced tight junction barrier dysfunction.

a, b The results with siERK1 and siERK2, respectively. Data are expressed as the mean ± SD. Values in the control group are set to 100% and other values are given relative to those in the control group. (n = 6/group). **p < 0.01 compared with corresponding control (same color) group or as indicated.
