NLRC5 attenuates inflammatory response in IL-1β-stimulated human osteoarthritis chondrocytes through the NF-κB signaling pathway


Figure 2. Overexpression of NLRC5 attenuated IL-1β-induced inflammatory injury in human OA chondrocytes. The pcDNA3.1-NLRC5 or pcDNA3.1 vector was transfected into chondrocytes, followed by IL-1β (10 ng/ml) stimulation for 24 h. (A) The expression levels of NLRC5 in chondrocytes were measured using western blot after transfection. (B) Cell viability of chondrocytes was detected using MTT assay. (CF) The mRNA and protein levels of iNOS and COX-2 were measured using RT-PCR and western blot analysis. (G, H) The production of NO and PGE2 in chondrocytes. *p < 0.05.
