CREB-H is a liver-enriched bZIP transcription factor of the CREB3 subfamily. CREB-H is activated by intramembrane proteolysis that removes a C-terminal transmembrane domain. Aberrant expression of CREB-H is implicated in liver cancer. In this study we characterized N-linked glycosylation of CREB-H in the luminal domain at the C-terminus. We found that CREB-H is modified at three N-linked glycos...

OBJECTIVE To examine the impact of low-density lipoprotein (LDL), an established mediator of atherosclerosis, on the transcription factor cAMP-response element-binding protein (CREB), which is a regulator of vascular smooth muscle cell (VSMC) quiescence. METHODS AND RESULTS VSMC CREB content is diminished in rodent models of diabetes and pulmonary hypertension. We examined aortic CREB content...

The cyclic AMP (cAMP)-response element binding protein (CREB) is an activity-dependent transcription factor playing a role in synaptic plasticity, learning and memory, and emotional behavior. However, the impact of Creb ablation on rodent behavior is vague as e.g., memory performance of different Creb mutant mice depends on the specific type of mutation per se but additionally on the background...

BACKGROUND Transcription factors CREB, C/EBPβ and Jun regulate genes involved in keratinocyte proliferation and differentiation. We questioned if specific combinations of CREB, C/EBPβ and c-Jun bound to promoters correlate with RNA polymerase II binding, mRNA transcript levels and methylation of promoters in proliferating and differentiating keratinocytes. RESULTS Induction of mRNA and RNA po...

BACKGROUND The role of β-adrenergic stimulation on viral myocarditis has been investigated in animal models of viral myocarditis. Excess stimulation of β-adrenergic receptors by catecholamines causes phosphorylation/activation of cAMP response element binding protein (CREB) by the cAMP signaling pathway. CREB as an important regulator of gene expression mediates the cardiovascular remodeling pr...

Animals change their behavior and metabolism in response to external stimuli. cAMP response element binding protein (CREB) is a signal-activated transcription factor that enables the coupling of extracellular signals and gene expression to induce adaptive changes. Biogenic amine neurotransmitters regulate CREB and such regulation is important for long-term changes in various nervous system func...

Activity-regulated transcription has been implicated in adaptive plasticity in the CNS. In many instances, this plasticity depends upon the transcription factor CREB. Precisely how neuronal activity regulates CREB remains unclear. To address this issue, we examined the phosphorylation state of components of the CREB transcriptional pathway. We show that NMDA activates transcription of CREB-resp...

BACKGROUNDS The cyclic AMP response element-binding protein (CREB) plays an important role in neuropathic pain. Kinesin superfamily motor protein 17 (KIF17) is involved in long-term memory formation. CREB could increase the level of KIF17 when activated by synaptic input. This study is to investigate the role and mechanism of CREB antisense oligonucleotide (ODN) in neuropathic pain induced by c...

The transcription factor cAMP response element binding protein (CREB) is implicated in the actions of drugs of abuse in several brain areas, but little information is available about a role for CREB in the ventral tegmental area (VTA), one of the key reward regions of the brain. Here, we demonstrate that chronic exposure to drugs of abuse induces CREB activity throughout the VTA. Using viral-me...

Although odorants are known to activate olfactory receptor neurons through cAMP, the long-term effects of odorant detection are not known. Our recent findings indicate that there is also a delayed and sustained cAMP response, with kinetics sufficient to mediate long-term cellular responses. This cAMP response is mediated by cGMP through activation of adenylyl cyclase by protein kinase G (PKG). ...
