...Glorianne Lazaro; Eleftherios Kostaras; Igor Vivanco Aberrant activation of the PI3K pathway is one of the commonest oncogenic events in human cancer. AKT is a key mediator of PI3K oncogenic function, and thus has been intensely pursued as a therapeutic target. Multiple AKT inhibitors, broadly...

...Katharina M. Siess; Thomas A. Leonard Akt is an essential protein kinase activated downstream of phosphoinositide 3-kinase and frequently hyperactivated in cancer. Canonically, Akt is activated by phosphoinositide-dependent kinase 1 and mechanistic target of rapamycin complex 2, which phosphorylate...

...Aswin G. Abraham; Eric O’Neill Mutations activating the PI3K (phosphoinositide 3-kinase)/Akt signalling pathway and inactivating the TP53 tumour-suppressor gene are common mechanisms that cancer cells require to proliferate and escape pre-programmed cell death. In a well-described mechanism, Akt...

...Camilla Norrmén; Ueli Suter Akt signalling has emerged as one of the major pathways involved in myelination, implicated in the regulation of several steps during the development of myelinating Schwann cells and oligodendrocytes. One of the main pathways intimately linked with Akt is mTOR [mammalian...

...Edita Aksamitiene; Anatoly Kiyatkin; Boris N. Kholodenko In the present paper, we describe multiple levels of cross-talk between the PI3K (phosphoinositide 3-kinase)/Akt and Ras/MAPK (mitogen-activated protein kinase) signalling pathways. Experimental data and computer simulations demonstrate...

... encoding enzymes required for fatty acid and cholesterol biosynthesis. Lipid metabolism is perturbed in some diseases and SREBP target genes, such as FASN (fatty acid synthase), have been shown to be up-regulated in some cancers. We have previously shown that mTORC1 plays a role in SREBP activation and Akt...

...) and Rag GTPases, acting upstream of mTORC1 [ 9 ]. More recently, rictor has also been shown to regulate autophagy, independently of mTORC1 in muscle cells under fasting conditions, where a decrease in Akt activity allowed FOXO transcription factors to enter the nucleus and transcriptionally regulate...

Given that recombinant influenza A viruses unable to activate PI3K signalling are attenuated in tissue culture, the PI3K pathway could be a novel target for the development of future anti-influenza drugs. Akt...

...J.-H. Paik The mammalian FoxO (forkhead box O) transcription factors FoxO1, FoxO3 and FoxO4 represent one of several effector arms of the PI3K (phosphoinositide 3-kinase)–Akt signalling network that has been linked to cancer, metabolism and aging. Specific roles of the FoxOs in the vascular cell...

The distribution and time course of Akt activation are similar to those of increased PtdIns(3,4) P 2 levels. These observations suggest that the increase in PtdIns(3,4) P 2 and the subsequent...
