Figure Legend Snippet: ZBP1 is essential for chondrocyte damage. Chondrocytes were transfected with siNC or ZBP1 siRNA for 24 h following TNF-α induction for 24 h. (A, B) Western blots and quantitative analysis of ZBP1, MMP13, and MMP3 expression levels ( n = 3). (C, D) Western blots and quantitative analysis of SOX9 expression levels. (E, F) Western blot and quantitative analysis of iNOS expression levels ( n = 3). (G) qPCR results showing the relative expression levels of Zbp1 and Inos ( n = 3). (H-K) Immunofluorescence staining and fluorescence intensity analysis of the relative expression levels of COL2A1 and MMP13 ( n = 3; scale bar: 50 μm). Chondrocytes were transfected with siNC or ZBP1 siRNA following TSZ (20 ng/ml TNF-α, 100 nM Smac mimetic, and 20 mM Z-VAD) induction for 12 h. (L, M) Western blots and quantitative analysis of ZBP1, P-RIPK3, and P-MLKL expression levels ( n = 3). The data are shown as the means ± SDs. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
Techniques Used: Transfection, Western Blot, Expressing, Immunofluorescence, Staining, Fluorescence
Figure Legend Snippet: ZBP1 is essential for OA progression in DMM mice. (A, B) IHC staining showing ZBP1-positive cells in the cartilage of the four groups (scale bar: 100 μm). (C, D) Safranin O/fast green staining, H&E staining and OARSI scores of the four groups (sham + AAV9-shGFP, n = 8; sham + AAV9-shZBP1, n = 8; DMM + AAV9-shGFP, n = 8; DMM + AAV9-shZBP1, n = 8; scale bar: 200 μm). (E-H) IHC staining showing COL2A1-positive cells and MMP13-positive cells in the cartilage of the four groups (scale bar: 100 μm). (I) Images showing 3D reconstructions of mouse joints; the black arrow indicates an osteophyte (scale bar: 1 mm). (J, K) Transverse sectional images and statistical analysis of the maximum osteophyte outgrowth of each joint in the four groups; the white arrow indicates the osteophyte (scale bar: 1 mm). The data are shown as the means ± SDs. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
