Hypoxia and the hypoxia-inducible factor 1alpha (Hif1alpha) are known to play critical physiological functions in endochondral bone development. However, their role in abnormal cartilage formation (chondrodysplasia) is unknown. Our goal was to test the possibility that altered oxygen homeostasis, which would result in abnormal Hif1alpha expression and activity, could lead to chondrodysplasia. This was done using matrix metalloproteinase (MMP) 9 and 13 deficient mice, which pre...
