TL;DR: It is shown that Beclin 1, an essential autophagy and tumor suppressor protein, is a target of the protein kinase Akt, and Akt-mediated phosphorylation of BeClin 1 functions in Autophagy inhibition, oncogenesis, and the formation of an autophile-inhibitory BeclIn 1/14-3-3/vimentin intermediate filament complex.
Abstract: Aberrant signaling through the class I phosphatidylinositol 3-kinase (PI3K)-Akt axis is frequent in human cancer. Here, we show that Beclin 1, an essential autophagy and tumor suppressor protein, is a target of the protein kinase Akt. Expression of a Beclin 1 mutant resistant to Akt-mediated phosphorylation increased autophagy, reduced anchorage-independent growth, and inhibited Akt-driven tumorigenesis. Akt-mediated phosphorylation of Beclin 1 enhanced its interactions with 14-3-3 and vimentin intermediate filament proteins, and vimentin depletion increased autophagy and inhibited Akt-driven transformation. Thus, Akt-mediated phosphorylation of Beclin 1 functions in autophagy inhibition, oncogenesis, and the formation of an autophagy-inhibitory Beclin 1/14-3-3/vimentin intermediate filament complex. These findings have broad implications for understanding the role of Akt signaling and intermediate filament proteins in autophagy and cancer.

TL;DR: Current data suggests that conventional antidepressants and ketamine mediate their antidepressant-like effects by increasing BDNF in forebrain regions, in particular the hippocampus, making BDNF an essential determinant of antidepressant efficacy.

TL;DR: The ability of p53 to interact physically and functionally with a co-activator (CBP) that has histone acetyltransferase activity, and with components (TAFs), of the general transcription machinery indicates that it may have different functions in a multistep activation pathway.
Abstract: The tumour suppressor p53 is a transcriptional regulator whose ability to inhibit cell growth is dependent upon its transactivation function. Here we demonstrate that the transcription factor CBP, which is also implicated in cell proliferation and differentiation, acts as a p53 coactivator and potentiates its transcriptional activity. The amino-terminal activation domain of p53 interacts with the carboxy-terminal portion of the CBP protein both in vitro and in vivo. In transfected SaoS-2 cells, CBP potentiates activation of the mdm-2 gene by p53 and, reciprocally, p53 potentiates activation of a Gal4-responsive target gene by a Gal4(1-147)-CBP(1678-2441) fusion protein. A double point mutation that destroys the transactivation function of p53 also abolishes its binding to CBP and its synergistic function with CBP. The ability of p53 to interact physically and functionally with a coactivator (CBP) that has histone acetyltransferase activity and with components (TAFs) of the general transcription machinery indicates that it may have different functions in a multistep activation pathway.

TL;DR: Future work needs to understand how CREB and DeltaFosB, acting in concert with numerous other drug-induced molecular changes in nucleus accumbens and many other brain regions, interact with one another to produce the complex behavioral phenotype that defines addiction.
