MA inhibited IL-1β-stimulated ECM degeneration in NPCs. (A-D) The expressions of anabolic-related proteins (Aggrecan, Collagen II, and Collagen I) and catabolic-related proteins (Mmp2, Mmp3, Mmp9, and Mmp13) in NPCs were analyzed with western blotting. (E-G) the expressions of Collagen II and Mmp13 were detected by immunofluorescence, scalebar = 200 μm. (H) The mRNA expression of Collagen II and Mmp13 were analyzed by RT-qPCR. Data were shown as means ± SD, n = 3. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ns, no significant difference
