Ceramides 11-19 AKT serine/threonine kinase 1 Homo sapiens 114-117 19959757-1 2010 OBJECTIVE: Ceramide is now recognized as a negative regulator of insulin signaling by impairing protein kinase B (PKB)/Akt activation. Ceramides 11-19 AKT serine/threonine kinase 1 Homo sapiens 119-122 19959757-2 2010 In different cells, two distinct mechanisms have been proposed to mediate ceramide inhibition of PKB/Akt: one involving atypical protein kinase C zeta (PKCzeta) and the other the protein phosphatase-2 (PP2A). Ceramides 74-82 AKT serine/threonine kinase 1 Homo sapiens 97-100 19959757-2 2010 In different cells, two distinct mechanisms have been proposed to mediate ceramide inhibition of PKB/Akt: one involving atypical protein kinase C zeta (PKCzeta) and the other the protein phosphatase-2 (PP2A). Ceramides 74-82 AKT serine/threonine kinase 1 Homo sapiens 101-104 19959757-5 2010 RESULTS: Although the PKCzeta-mediated negative effect of ceramide on insulin-stimulated PKB/Akt was dominant in adipocytes, a ceramide action through PP2A outside CEMs, prevented by OKA, was also unraveled. Ceramides 58-66 AKT serine/threonine kinase 1 Homo sapiens 70-96 19959757-8 2010 CONCLUSIONS: Our results show that ceramide can switch from a PKCzeta-dependent mechanism to a PP2A pathway, acting negatively on PKB/Akt, and hence revealing a critical role of CEMs of the PM in this process.
