Fig. 3. Inhibitory effects of periplanetasin-5 on iNOS and COX-2 expression in LPS-stimulated Raw264.7 cells. (A) The levels of iNOS (left) and COX-2 (right) mRNA were determined by quantitative real-time PCR. (B) The protein expression levels of iNOS and COX-2 were determined through western blot analysis. Data shown are means ± SD of triplicate experiments. #p < 0.05 compared to the control group. ***p < 0.001, **p < 0.01, *p < 0.05 compared to the LPS group. CTR, control; LPS, lipopolysaccharide.
