Central role of mitochondria and p53 in Fas-mediated apoptosis of rheumatoid synovial fibroblasts

Abstract
Objective. Fas-mediated apoptosis is preferentially observed in synoviocytes of patients with rheumatoid arthritis (RA) and is associated with the pathophysiological process of RA. To clarify the molecular mechanisms of Fas-mediated apoptosis of RA synoviocytes, we investigated the role of the mitochondrial pathway and tumour suppressor p53 in this process.
