TLDR
It is demonstrated that Akt also regulates the activity of FKHRL1, a member of the Forkhead family of transcription factors, which triggers apoptosis most likely by inducing the expression of genes that are critical for cell death, such as the Fas ligand gene.About:

Cell signaling by receptor-tyrosine kinases
TL;DR: Understanding of the complex signaling networks downstream from RTKs and how alterations in these networks are translated into cellular responses provides an important context for therapeutically countering the effects of pathogenic RTK mutations in cancer and other diseases.

AKT/PKB signaling: navigating downstream.
TL;DR: Those Akt substrates that are most likely to contribute to the diverse cellular roles of Akt, which include cell survival, growth, proliferation, angiogenesis, metabolism, and migration are discussed.

Phosphorylation and regulation of Akt/PKB by the rictor-mTOR complex
TL;DR: In this paper, the rictor-mTOR complex was used to identify compounds which modulate Akt activity mediated by the Rictor mTOR complex and methods for treating or preventing a disorder that is associated with aberrant Akt activation.
Journal ArticleDOI
Cellular survival: a play in three Akts
TL;DR: The mechanisms by which survival factors regulate the PI3K/c-Akt cascade, the evidence that activation of the PI 3K/ c-AKT pathway promotes cell survival, and the current spectrum of c- akt targets and their roles in mediating c- Akt-dependent cell survival are reviewed.

Akt Phosphorylation of BAD Couples Survival Signals to the Cell-Intrinsic Death Machinery
Sandeep Robert Datta,Henryk Dudek,Xu Tao,Shane C. Masters,Haian Fu,Yukiko Gotoh,Michael E. Greenberg +6 more
TL;DR: It is shown that growth factor activation of the PI3'K/Akt signaling pathway culminates in the phosphorylation of the BCL-2 family member BAD, thereby suppressing apoptosis and promoting cell survival.

Tumor suppressor p53 is a direct transcriptional activator of the human bax gene
T Miyashita,John C. Reed +1 more
TL;DR: The bax gene promoter region contains four motifs with homology to consensus p53-binding sites and wild-type but not mutant p53 protein bound to oligonucleotides corresponding to this region of the bax promoter, suggesting that bax is a p53 primary-response gene, presumably involved in a p 53-regulated pathway for induction of apoptosis.
