Figure 3. Dvl2 increases synovial apoptosis and reduces the secretion of inflammatory cytokines in the knee joints of CIA rats.
A. Synovial apoptosis in the knee joints was analyzed by TUNEL staining. B. Quantitative evaluation of TUNEL-positive synovial cells (n = 5/group). C. The level of intra-articular inflammatory cytokines was analyzed by ELISA (n = 10/group). *p < 0.05, **p < 0.01; CIA, collagen-induced arthritis; Normal, healthy rats without CIA; Dvl2, the knee joints of CIA rats injected with lentivirus-Dvl2; Control, the knee joints of CIA rats injected with lentivirus-control. Scale bars: 100 μm.
