Abstract

Little research has focused on the involvement of oxidative stress as it relates to the pathophysiology of osteoarthritis (OA); while inflammation has been extensively studied. The present study evaluates the ability to modulate the response of canine chondrocytes to both inflammation and oxidative stress in an in-vitro model. Chondrocytes were incubated and then stimulated to under-go oxidative stress by using hydrogen peroxide or inflammation using interleukin-1 beta and tumor necrosis factor alpha. For inhibition of oxidative stress an antioxidant, N-acetyl-cysteine, was used prior to induction with hydrogen peroxide in a subset of chondrocytes. Measures of oxidative stress were superoxide dismutase and reduced glutathione. Prostaglandin E2 was used as a measurement of inflammation. Chondrocytes responded appropriately to both oxidative stress and inflammation. The antioxidant N-acetyl-cysteine provided adequate protection against oxidative stress. Oxidative stress and inflammation should be considered to play a role in the pathophysiology of canine OA.
