Repetitive cycles of hypoxia and reoxygenation associated with changes in synovial perfusion are postulated to activate hypoxia - inducible factor - 1alpha and nuclear factor - kappaB , two key transcription factors that are regulated by changes in cellular oxygenation and cytokine stimulation , and that in turn orchestrate the expression of a spectrum of genes critical to the persistence of synovitis .
