Excerpt
The synovial microenvironment in rheumatoid arthritis (RA) is often hypoxic with evidence of anaerobic metabolism. This results from an imbalance between high metabolic demands and impaired tissue perfusion due to microvascular damage. Cellular responses to hypoxia are mediated by the transcription factor HIF-1α, which is exquisitely and rapidly controlled by cellular oxygen tension. HIF-1α has been shown to play a key role in promoting tumor angiogenesis, and was recently shown to be critically important in inflammatory responses. …
