Structure of reactive oxidative molecules in mitochondrion. Disruption of chondrocytes by nitric oxide induced inhibition is involved in chondrocyte functional compromise. Nitric oxide (NO) is released with several pro-inflammatory factors by synovial cells as a result of inflammatory transition. The nuclear transcription factor (NF-t) involved in the upregulation of several inflammatory genes is an important factor for the ROS/RNS induced inflammatory transition of synovial membrane, mainly by NO related TNF-α and IL-1 induction damage of mitochondrial DNA.
