Figure 10. Knockdown of LOXL1 inhibited inflammatory reaction of RA synovial cells. (A) IL-6, INOS and COX2 mRNA expression levels were analyzed using qPCR. (B) IL-6, INOS and COX2 protein levels were detected using western blot. (C) Quantitative analysis of western blot results. (D) Validation of IL-6 and COX2 expression using cellular immunofluorescence. *P < 0.05, **P < 0.01, ***P < 0.001.
