Effect of phosphoinositide-dependent kinase 1 on protein kinase B translocation and its subsequent activation.
In this report we investigated the function of phosphoinositide-dependent protein kinase 1 (PDK1) in protein kinase B (PKB) activation and translocation to the cell surface. Wild-type and PDK1 mutants were transfected into HeLa cells, and their subcellular localization was analyzed. PDK1 was found to translocate to the plasma membrane in response to insulin, and this process did not require a f...
متن کاملCharacterization of a 3-phosphoinositide-dependent protein kinase which phosphorylates and activates protein kinase Bα
Background: Protein kinase B (PKB), also known as c-Akt, is activated rapidly when mammalian cells are stimulated with insulin and growth factors, and much of the current interest in this enzyme stems from the observation that it lies ‘downstream’ of phosphoinositide 3-kinase on intracellular signalling pathways. We recently showed that insulin or insulin-like growth factor 1 induce the phospho...
متن کاملThe Effect of Protein Kinase-B on FOXO Autophagy Family Proteins (FOXO1 and FOXO3a) Following High Intensity Interval Training in the Left Ventricle of the Heart of Diabetic Rats by Streptozotocin and Nicotinamide
Background: FOXO family proteins are important factors in autophagy pathway. Protein kinase-B is an important regulator for this family that can be regulated through exercise training. Therefore, the aim of this study is to investigate the effect of protein kinase-B (PKB) on FOXO autophagy family proteins (FOXO1 and FOXO3a) following high intensity interval training (HIIT) in the left ventricle...
متن کاملAntiapoptotic signaling in LNCaP prostate cancer cells: a survival signaling pathway independent of phosphatidylinositol 3'-kinase and Akt/protein kinase B.
Constitutive activation of the phosphatidylinositol 3'-kinase (PI3 kinase)-Akt/protein kinase B (PKB) "survival signaling" pathway is a likely mechanism by which many cancers become refractory to cytotoxic therapy. In LNCaP prostate cancer cells, the PTEN phosphoinositide phosphatase is inactivated, leading to constitutive activation of Akt/PKB and resistance to apoptosis. However, apoptosis an...
متن کاملMuscarinic receptors mediate phospholipase C-dependent activation of protein kinase B via Ca2+, ErbB3, and phosphoinositide 3-kinase in 1321N1 astrocytoma cells.
In 1321N1 astrocytoma cells, heterotrimeric G-protein-coupled receptors that activate phosphoinositide-specific phospholipase Cbeta (PLCbeta) isoforms via G(q), induced a prolonged activation of protein kinase B (PKB) after a short delay. For example, the effect of carbachol acting on M3 muscarinic receptors is blocked by wortmannin, suggesting it is mediated via a phosphoinositide 3-kinase (PI...
