Fig. 5From: Inhibition of Nrf2/HO-1 signaling leads to increased activation of the NLRP3 inflammasome in osteoarthritisHistology and IHC staining of the synovium in OA model rats. a Histochemistry and IHC staining of the synovium from the sham, 4-week and 8-week OA groups. Representative images are shown above. Scale bar = 100 μm. b Relative expression level of NLRP3. c Relative expression level of ASC. d Relative expression level of Nrf2. e Relative expression level of HO-1 (n = 8, *P < 0.05, **P < 0.01 vs sham)Back to article page
