(Submitter supplied) In this study we show that, in embryonic fibroblasts from mice on a high fat diet and treated with Forskolin, ionizing radiation exposure or both, phosphorylation of CREB-binding protein (CREB) by ATM (ataxia-telangiectasia-mutated) and casein kinases 1 and 2 (CK1 and CK2) on a cluster of five phosphorylation sites (the ATM/CK cluster) within the unstructured kinase-inducible domain (KID) provides an additional level of regulation through dynamic modulation of CREB DNA binding activity. more...

(Submitter supplied) The CREB family of transcription factors stimulates cellular gene expression following phosphorylation at a conserved serine (Ser133 in CREB1) in response to cAMP and other extracellular signals. In order to characterize CREB target genes in various tissues, we give a cAMP agonist, forskolin (FSK), to cell lines or primary cultures and monitor the gene expression. To eliminate CREB-independent effects of FSK on cellular gene expression, we employed a dominant negative form of CREB called A-CREB, which dimerizes selectively with and blocks the DNA binding activity of CREB but not other bZIP family members. more...

(Submitter supplied) Populations of circulating immune cells are maintained in equilibrium through signals that enhance the retention or egress of hematopoietic stem cells (HSCs) from bone marrow (BM). Prostaglandin E2 (PGE2) stimulates HSC renewal and engraftment, for example, via induction of the cAMP pathway. Triggering of PGE2 receptors increases HSC survival in part via the PKA-mediated induction of the CREB signaling pathway. more...

(Submitter supplied) During fasting, increases in circulating pancreatic glucagon maintain glucose balance by up-regulating hepatic gluconeogenesis. Triggering of the cAMP pathway stimulates the gluconeogenic program through the phosphorylation of CREB and via the de-phosphorylation of the CREB coactivator CRTC2. Hormonal and nutrient signals are also thought to modulate gluconeogenic genes by promoting epigenetic changes that facilitate assembly of the transcriptional machinery, although the nature of these modifications is unclear. more...

Analysis of C57BL6/J primary hepatocytes depleted of either lysine acetyltransferase 2B (KAT2B) or WD repeat-containing protein 5 (WDR5) via shRNA knockdown, then stimulated with glucagon for 90 minutes. Results provide insight into the roles of KAT2B and WDR5 in hepatic gluconeogenesis.

(Submitter supplied) In fasted mammals, glucose homeostasis is maintained through activation of the cAMP responsive CREB coactivator TORC2, which stimulates the gluconeogenic program in concert with the forkhead transcription factor FOXO1. Here we show that starvation also triggers TORC activation in Drosophila, where it maintains energy balance by promoting the expression of CREB target genes in the brain. TORC mutant flies have reduced glycogen and lipid stores, and they are sensitive to starvation as well as oxidative stress. more...

(Submitter supplied) Differential expression analysis used the DESeq2 Bioconductor package, a model based on the negative binomial distribution. the estimates of dispersion and logarithmic fold changes incorporate data-driven prior distributions, Padj of genes were setted <0.05 to detect differential expressed ones.Our study represents the detailed analysis of of NP1 and NP1/CRTCHA drosophila gut transcriptomes, with biologic replicates, generated by RNA-seq technology.Transcriptome analysis indicated that the genes involved in proteasome assembly, ROS scavengers, and protein folding were highly enriched among those differentially expressed genes (DEGs) in CRTC overexpressing (CRTCOE) intestines.

(Submitter supplied) Metabolic homeostasis in mammals critically depends on the regulation of fasting-induced genes by CREB in the liver. Previous genome-wide analysis has shown that only a small percentage of CREB target genes are induced in response to fasting-associated signaling pathways. The precise molecular mechanisms by which CREB specifically targets these genes in response to alternating hormonal cues remain to be elucidated. more...
