Increased Expression of the Akt/PKB Inhibitor TRB3 in Osteoarthritic Chondrocytes Inhibits IGF-1 Mediated Cell Survival and Proteoglycan Synthesis

OBJECTIVE: The chondrocyte response to IGF-1 is reduced with aging and in OA. IGF-1 signals through the PI-3 kinase/Akt pathway. TRB3, a tribbles homolog, has been shown to inhibit IGF-1 activation of Akt in HEK293 cells. In this study, we determined if TRB3 is expressed in chondrocytes and if TRB3...
