Chondrosarcomas are the second most common cause of bone cancer and are removed surgically with wide margins. On recurrence, they are resistant to chemo and radiation therapy and new treatment options are critically required. This tumor type produces hyaline cartilage, a cartilage normally formed under hypoxic and acidic environment due to lack of vasculature in cartilage. Paradoxically, chondrosarcomas arise in the well vascularized, oxygen rich environment of the bone. Hypoxia and acidosis are two stressors where the cellular effects are typically reported separately even though cells experience combined effects of hypoxia and acidosis. Given the mechanistic links between hypoxia and …

The importance of understanding how costal cartilage chondrocytes respond to stimuli such as oxidative stress and low pH has been largely overlooked in studies involving tissue culturing due to major differences between oxygen and pH levels during incubation and the natural environment of hyaline cartilage. Hyaline cartilage is avascular and naturally hypoxic which subsequently leads to increased glycolytic metabolism and ultimately causes a decrease in extracellular pH. To examine how healthy costal cartilage responds to these extreme growth conditions, we examined responses in three hyaline cartilage diseases. Our ability to identify the disease mechanisms responsible for pectus excavatum, pectus carinatum, …
