Abstract

Pro-inflammatory cytokines such as interleukin-1β (IL-1β) and tumor necrosis factor- alpha (TNF-α) play a key role in the pathogenesis of osteoarthritis (OA). Once released, these cytokines are potent stimulators for the de novo production of catabolic enzymes such as matrix metalloproteinases (MMPs) and cyclo-oxygenase-2 (COX-2). Anti-inflammatory agents capable of suppressing the production and catabolic actions of these cytokines may have therapeutic potential in the treatment of OA and a range of other osteoarticular disorders. The purpose of this study was to examine the therapeutic effect of Curcumin (diferuloylmethane), a pharmacologically safe phytochemical agent, on males and foals affected by degenerative joint diseases. Curcumin, in the form phytosome (CURCUVET ®, Indena Spa, Milan, Italy) was administered to animals for fifteen days and gene expression was monitored before the treatment and after four, eight, and fifteen days. In mares, Curcumin inhibited the expression of COX-2, TNF-α, IL-1β, IL1RN, and IL6, even if only the downregulation of IL-1β and IL1RN were significant. In foals, Curcumin significantly inhibited the expression of COX-2, TNF-α, IL1RN and significantly increased that of IL6. These results indicate that Curcumin has nutritional potential as a natural anti-inflammatory agent for treating osteoarticular
