Fig. 4From: Water-separated part of Chloranthus serratus alleviates lipopolysaccharide- induced RAW264.7 cell injury mainly by regulating the MAPK and Nrf2/HO-1 inflammatory pathwaysEffects of CSSPW on mRNA expression levels of COX-2 (a), iNOS (b) in LPS-induced RAW264.7 cells. Cells were incubated with CSSPW (15 ng/mL, 1.5 μg/mL and 150 μg/mL), Dex (0.13 mg/mL) and LPS (1 μg/mL) for 24 h. COX-2 and iNOS mRNA expression levels were detected by qPCR. Data were represented as mean ± SD (n = 6). **p < 0.01 vs. the Con group; #p < 0.05, ##p < 0.01 vs. the LPS group; $$p < 0.01 vs. the 15 ng/mL groupBack to article page
