Four-Octyl Itaconate Protects Chondrocytes against H2O2-Induced Oxidative Injury and Attenuates Osteoarthritis Progression by Activating Nrf2 Signaling

Figure 2

OI inhibited H2O2-stimulated cell death and apoptosis in primary murine chondrocytes. Primary murine chondrocytes were added with OI (25 μM) or vehicle control (“Veh”), followed by H2O2 (300 μM) stimulation. Cell viability (a), cell death (b), caspase-3 activity (c), accumulation of single-stranded DNA (ssDNA) contents (d), and apoptosis (e) were assessed. (f, g) Annexin V FACS assays were performed. The values are represented as . vs. “Ctrl” group. # vs. cells treated with H2O2 only.
