Burgering Forkhead transcription factors: new insights into protein kinase B (c-akt) signaling Received: 19 July 1999 / Accepted: 6 September 1999 / Published online: 23 September 1999 Abstract The proto-oncogene protein kinase B (PKB), activities of certain viruses, and the negative regulator of also known as c-Akt, is a central player in a signaling this pathway, PTEN, is a tumor suppressor. The identifi- pathway of which many components have been linked to cation of particular downstream targets of PKB has pro- tumorigenesis. Active forms of PKB as well as of its up- vided us with new insights into the possible mechanism stream activator phosphatidylinositol 3-kinase (PI3K) of PI3K/PKB-mediated tumorigenicity. Recently a sub- have been found to be responsible for the transforming family of Forkhead transcription factors was identified as additional targets for PI3K/PKB signaling. This re- view discusses the studies that have led to this conclu- sion and the possible implications of this finding for our understanding of how PI3K/PKB activity could lead to oncogenesis.
