Hck enhances IL-1β-induced ECM degradation, inflammation, and apoptosis in chondrocytes via JAK-STAT3 signaling pathway. A Western blot analysis of JAK-STAT3 signaling proteins in IL-1β-stimulated chondrocytes following Hck knockdown and colivelin treatment. B CCK-8 assay measuring cell viability in IL-1β-stimulated chondrocytes following Hck knockdown and colivelin treatment. C-D ELISA examined the levels of inflammatory markers in IL-1β-stimulated chondrocytes following Hck knockdown and colivelin treatment. E Cell apoptosis in IL-1β-stimulated chondrocytes following Hck knockdown and colivelin treatment was measured by flow cytometry. F-G Western blot analyzed the levels of apoptosis and ECM-related proteins in IL-1β-stimulated chondrocytes following Hck knockdown and colivelin treatment. P < 0.01, vs. control group. ##P < 0.01, vs. IL-1β group. &&P < 0.01, vs. IL-1β-si-Hck#2 group
