TLDR
The transcription factor CREB functions in glucose homeostasis, growth-factor-dependent cell survival, and has been implicated in learning and memory, and how is specificity achieved in these signalling pathways?
Abstract
The transcription factor CREB -- for 'cyclic AMP response element-binding protein' -- functions in glucose homeostasis, growth-factor-dependent cell survival, and has been implicated in learning and memory. CREB is phosphorylated in response to various signals, but how is specificity achieved in these signalling pathways?

Wnt-Frizzled signalling and the many paths to neural development and adult brain homeostasis.

TL;DR: Key findings showing the pivotal nature of Wnt-Frizzled (FZD) signaling in neurogenesis as revealed by a number of molecular genetic studies using mice and other model organisms are reviewed.

CREB Is Activated by Muscle Injury and Promotes Muscle Regeneration

TL;DR: It is shown that CREB phosphorylation and target genes are induced after acute muscle injury and during regeneration due to genetic mutation, and a new physiologic function for CREB is revealed in contributing to skeletal muscle regeneration.

Impaired insulin secretion in a mouse model of ataxia telangiectasia

TL;DR: It is shown that young Atm-deficient mice show normal fasting glucose levels and normal insulin sensitivity, however, oral glucose tolerance testing revealed delayed insulin secretion and resulting transient hyperglycemia, indicating a role for ATM in metabolic function.
Journal ArticleDOI

cDNA gene expression profile of rat hippocampus after chronic treatment with antidepressant drugs.

TL;DR: A significant number and homology in gene expression were observed with the three antidepressants and many of the genes were associated with neurogenesis and synaptogenesis, including synaptophysin and neogenin.

Adenosine stimulates CREB activation in macrophages via a p38 MAPK-mediated mechanism.

TL;DR: Some of the immunomodulatory effects of adenosine in macrophages may be explained by its augmenting effect on CREBactivation, indicating that p38 MAPK but not p42/44 MAPK is an upstream mediator of CREB activation.

Cyclic AMP stimulates somatostatin gene transcription by phosphorylation of CREB at serine 133

TL;DR: Results suggest that phosphorylation of CREB may stimulate transcription by a mechanism other than by simply providing negative charge, as CREB mutants containing acidic residues in place of the Ser-133 phosphoacceptor were also transcriptionally inactive.
Journal ArticleDOI

Phosphorylated CREB binds specifically to the nuclear protein CBP

TL;DR: It is proposed that CBP may participate in cAMP-regulated gene expression by interacting with the activated phosphorylated form of CREB, which is activated as a result of phosphorylation by protein kinase A7.
Journal ArticleDOI

Cell survival promoted by the Ras-MAPK signaling pathway by transcription-dependent and -independent mechanisms.

TL;DR: The findings suggest that the MAPK signaling pathway promotes cell survival by a dual mechanism comprising the posttranslational modification and inactivation of a component of the cell death machinery and the increased transcription of pro-survival genes.

Deficient long-term memory in mice with a targeted mutation of the cAMP-responsive element-binding protein

TL;DR: Consistent with models claiming a role for long-term potentiation (LTP) in memory, LTP in hippocampal slices from CREB mutants decayed to baseline 90 min after tetanic stimulation, however, paired-pulse facilitation and posttetanic potentiation are normal.
Journal ArticleDOI

Nuclear protein CBP is a coactivator for the transcription factor CREB

TL;DR: Fluorescence anisotropy measurements are used to define the equi-librium binding parameters of the phosphoCREB:CBP interaction and report here that CBP can activate transcription through a region in its carboxy terminus.
