β-Actin is used as a standard control. The expression of TLR4 decreased significantly in DM–Fgl2–RNAi group compared with GFP group and DM group (P<0.05). The expression of p38 MAPK in DM–Fgl2–RNAi group decreased significantly compared with GFP group and DM group (P<0.05). Data are given as the means±S.D.s. ^#P<0.05 compared with normal; *P<0.05 compared with DM–Fgl2–RNAi, ^☆P > 0.05 compared with GFP group, ^▽P<0.001 compared with normal; ^＊P > 0.05 compared with normal.
