Researchers have found that sustained expression of excess hypoxia-inducible factor (HIF)-1α leads to unwanted formation of blood vessels (angiogenesis) that destroys cartilage and causes osteoarthritis. A necessary but destructive factor Being required for extracellular matrix (ECM) construction and energy in the absence of oxygen, HIF-1α is necessary for cartilage-building cells (chondrocytes), which normally live in...

In Aging Cell, researchers have published a potential method of ameliorating disc degeneration that focuses on the cells living in a low-oxygen environment within the discs. Living on low oxygen Yesterday, we discussed how an antioxidant compound was found to alleviate intervertebral disk degeneration (IVDD). This related paper focuses on a tissue that is already...
