Fig. 6. Targeting miR-18a sensitized chondrocytes in OA lesions to anticytokine drugs.

Fig. 6

a AS101 (1 mg/kg) was intraperitoneal injected, and 10 μL antagomir of miR-18a (250 nM) were intra-articular injected in rat model of knee OA every 3 days, followed by dissociation of knee joint after 4 weeks. HE staining, Safarin O, and fast green staining, and IHC of p65, p-SMAD2/3, and RUNX2 were conducted. Scale bar: 50 μm. b Mankin’s score was assessed. c Expression of SERPINE1 and RUNX2 in articular cartilage from OA rats with administration of AS101 or combination of AS101 and miR-18a antagomir. d qRT-PCR to determine the expression of hypertrophy-related genes in human ACs and SW1353 cells with treatment of adalimumab or combination of adalimumab and miR-18a antagomir. Data in bd are presented as mean ± SD. *P < 0.05.
