Activation of cyclic AMP response element-binding protein (CREB) in aggressive periodontal disease.
Quintessence international (Berlin, Germany : 1985), 2009 To report a novel observation of neutrophil signal transduction abnormalities in patients with localized aggressive periodontitis (LAP) that are associated with an enhanced phosphorylation of the nuclear signal transduction protein cyclic AMP response element-binding factor (CREB).Peripheral venous blood neutrophils of 18 subjects, 9 patients with LAP ...

Journal of Neurochemistry, 1996
Abstract: We have recently demonstrated that mRNA expression of cyclic AMP (cAMP) response element‐binding protein (CREB) is down‐regulated in CATH.a cells (a neural‐derived cell line) by activation of the cAMP pathway. We now demonstrate that this down‐regulation can be accounted for by a decrease in the rate of CREB gene transcription.

Cyclic AMP‐Responsive Element Binding Protein in Brain Mitochondria
Journal of Neurochemistry, 1999Abstract: Cyclic AMP‐responsive element binding protein (CREB) is critically involved in many important brain functions, including the formation of long‐term memory. CREB is the best characterized member of a family of transcription factors (CREB/ATF family) recognized to be important nuclear targets for intracellular signal transduction systems. Here

Presence of a Cyclic AMP Response Element‐Binding Protein in Oligodendrocytes
Journal of Neurochemistry, 1993Abstract: Several lines of evidence indicate that cyclic AMP (cAMP) induces oligodendrocyte differentiation. However, the mechanism(s) of this stimulation remains unknown. Because in several cell types the transcriptional activity of various cAMP‐responsive genes is regulated through a cisacting DNA sequence known as cAMP response element (CRE), we ...

Role of cyclic AMP response element binding protein in human leukemias
Cancer, 2005AbstractAcute myeloid leukemia (AML) in adults has a 20% 5‐year disease‐free survival despite treatment with aggressive cytotoxic chemotherapy. Previous work from our laboratory demonstrated that the majority of patients with acute lymphoid and myeloid leukemia overexpress CREB in the bone marrow.

The purpose of the present study was to track the acute effects of ethanol on the cerebellar adenylyl cyclase cascade from membrane to nucleus and to determine how this important signaling pathway neuroadapts during chronic ethanol exposure. An acute ethanol challenge increased cyclic AMP content and protein kinase A activity by 80% compared to control

The present study was undertaken to examine the effect of paroxetine, a selective serotonin reuptake inhibitor, on the phosphorylation of cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) in the rat brain. Single administration of paroxetine significantly induces the phosphorylation of CREB in the rat frontal cortex and ...

Pituitary, 1998
The proopiomelanocortin (POMC) gene expressed in corticotrophs of the anterior pituitary encodes several biologically active peptides and is primarily under the positive control of hypophysiotropic factors (e.g. corticotropin releasing hormone). Using AtT20 cells as a model, we show that these factors increase levels of POMC primary RNA transcripts ...

Abstract The NF-kappaB family of transcription factors regulates the inducible expression of a variety of genes. Recently, we showed that elevation of intracellular cyclic AMP inhibits NF-kappaB-mediated transcription in human monocytes and endothelial cells without preventing nuclear translocation of NF-kappaB complexes.

Estrogen Modulation of the Cyclic AMP Response Element-Binding Protein Pathway
Neuroendocrinology, 2001Actions of estrogen include mechanisms leading to alterations in gene transcription that may be independent of nuclear estrogen receptors, as well as those involving direct action of the estrogen receptor on the genome. Also, the influence of estrogen in the brain appears to extend well beyond areas associated with reproduction and may include ...
