FoxOs increase antioxidants and further regulate multiple functions of chondrocytes. FoxOs possibly promote proliferation and block hypertrophic differentiation along with the PTEN/Akt/FoxO signaling. FoxOs also repress apoptosis and autophagy with altering the SIRT-1 protein level. PTEN = phosphatase and tensin homolog deleted on chromosome ten.
