Objective: To study a comprehensive proteomic analysis of celecoxib in oseteoarthritis (OA) chondrocytes. Methods: OA chondrocytes were stimulated with celecoxib, IL-1¦Â and IL-1¦Â together with celecoxib. Proteins were extracted from the cells and subjected to 2-dimensional differential image gel electrophoresis (2D-DIGE). Proteins of interest were identified by mass spectrometry. Results: Eighty-six protein spots showed significantly different intensities with each reagent or reagent combination. AAA+ protein, HSP47/Serpin, cAMP-dependent protein kinase type II-beta regulatory subunit, alpha-actin-4 and tubulin decreased with the addition of celecoxib, while apolipoprotein A-V, glutamate carboxipeptide 2, mitochondrial stress-70 protein, sorting nexin-9 and GRP78 increased with the addition of celecoxib. GRP78 is a stress protein and may be chondroprotective. Celecoxib modulated IL-1¦Â stimulated chondrocytes, and CD200R and moesin were identified as such resulting proteins. Conclusion: Protein profiles of OA chondrocytes changed after administration of celecoxib. Further investigation is needed to elucidate the function of each protein in OA chondrocytes.
