STAT3 inhibition and AMPK activation showed similar anti-inflammatory effect in mice. Mice were intraperitoneally injected with LPS (15 mg/kg) alone or LPS with BBR (10 mg/kg) or S3I-201 (5 mg/kg) and were sacrificed 6 h after LPS injection. (A) HE-staining images of lung tissue. Black arrows indicate infiltration of inflammatory cells. (B) Relative mRNA levels of inflammatory genes in lung tissue. (C) Relative mRNA levels of the STAT3 downstream genes Socs3 and Cox2 in lung tissue. Data are presented as means ± SD from 3 independent experiments **p < 0.01, ***p < 0.001, compared to LPS alone group; #p < 0.05, ##p < 0.01, ###p < 0.001, compared to LPS + BBR group. Bar represents 50 μm.
