Glaucocalyxin A Attenuates IL-1β-Induced Inflammatory Response and Cartilage Degradation in Osteoarthritis Chondrocytes via Inhibiting the Activation of NF-κB Signaling Pathway

Figure 1

Examination of cytotoxicity effect of GLA on human OA chondrocytes. (a) The chemical structure of GLA. (b) Primary human OA chondrocytes were prepared and incubated with different concentrations of GLA (0, 5, 10, 20, and 40 μM) for 24 h. Subsequently, cells were processed to test the cell viability using CCK-8 assay. Experiments were performed at least in triplicate. versus the control group.
