As this distribution is highly reminiscent of the distribution of cells containing the phosphatase inhibitor, DARPP-32, we raised the possibility that these two proteins may coexist in tanycytes and that DARPP-32 may modulate type 2 deiodinase activity by regulating the phosphorylation state of the cAMP regulatory factor, CREB.

This suggested that PEPCK was suppressed by GSK-3 inhibition-mediated inactivation of CREB.
|

Alpha-MSH has an activating effect on hypophysiotropic TRH neurons via the phosphorylation of CREB, and when administered exogenously, can completely reverse fasting-induced suppression of TRH mRNA in the PVN.
|

16310285
|
Neuropeptide Y may also modulate the effects of the melanocortin signaling system during fasting by potentiating the inhibitory actions of AGRP on hypophysiotropic TRH neurons to prevent the phosphorylation of CREB and through direct inhibitory effects on alpha-MSH-producing neurons in the arcuate nucleus.

Expression of CREB mutants in human islets resulted in significant (p < 0.001) activation of caspase-9, a key regulatory enzyme in the mitochondrial pathway of apoptosis, when compared with islets transduced with adenoviral beta galactosidase.
|
17 |
17593347
|
Furthermore, the anti-apoptotic action of growth factors exendin-4 and betacellulin in human islets exposed to cytokines was partially lost when CREB function was impaired.

We hypothesized that high GnRH pulse frequencies might stimulate a transcriptional repressor(s) to attenuate the action of CRE binding protein (CREB) and show that inducible cAMP early repressor (ICER) fulfills such a role.
|
21 |
20008557
|
ICER binds to the FSH beta CRE site to reduce CREB occupation and abrogates both maximal GnRH stimulation and GnRH pulse frequency-dependent effects on FSH beta transcription.
|
22 |
20008557
|
These data suggest that ICER production antagonizes the stimulatory action of CREB to attenuate FSH beta transcription at high GnRH pulse frequencies, thereby playing a critical role in regulating cyclic reproductive function.

Here we show that Creb activity during fasting is modulated by Cry1 and Cry2, which are rhythmically expressed in the liver.
|
28 |

|
Cry1 expression was elevated during the night-day transition, when it reduced fasting gluconeogenic gene expression by blocking glucagon-mediated increases in intracellular cAMP concentrations and in the protein kinase A-mediated phosphorylation of Creb.

Subsequent studies established that GIP increased phosphorylation of Serine 133 in cAMP-response element binding protein (CREB) and the nuclear localization of cAMP-responsive CREB coactivator 2 (TORC2) through a pathway involving phosphatidylinositol 3-kinase (PI3-K), PKB, and AMP-activated protein kinase (AMPK).

The action of GLP-1 at -410RIP1-LUC was also reduced by cotransfection with A-CREB, a genetically engineered isoform of the CRE binding protein CREB, which dimerizes with and prevents binding of basic-region-leucine-zipper (bZIP) transcription factors to the CRE.
|
31 |
10909973
|
On the basis of these studies, it is proposed that PKA-independent stimulatory actions of GLP-1 at RIP1 are mediated by bZIP transcription factors related in structure but not identical to CREB.

ANG II and 12(S)-HETE led to activation of p38(MAPK) and its target transcription factor cAMP-responsive element-binding protein (CREB).
|
33 |
12372774
|
ANG II- and 12(S)-HETE-induced CREB activation and [(3)H]leucine incorporation were blocked by the p38(MAPK) inhibitor SB-202190.
|
34 |
12372774
|
Thus p38(MAPK)-dependent CREB activation may mediate ANG II- and LO product-induced FN expression and cellular growth in rat MC.

Cyclic AMP response element-binding protein (CREB) stimulates beta cell Irs2 expression and is a major calcium/calmodulin-dependent kinase (CaMK)(IV) target in neurons.
|
36 |
21301804
|
We therefore hypothesised that CaMK(IV) mediates glucose-induced Irs2 expression in beta cells via CREB activation.
|
37 |
21301804
|
Similarly, overproduction of a constitutively active form of CaMK(IV) promoted sustained CREB phosphorylation and a significant increase in Irs2 but not Irs1 expression.
|
38 |
21301804
|
Finally, overproduction of a dominant negative form of CREB completely suppressed glucose and CaMK(IV) stimulation of Irs2 expression.

Treatment of HK-2 cells with an angiotensin II receptor 1 (AT1) blocker--losartan--prevented high-glucose-induced USF2 expression and high-glucose-enhanced phosphorylation of CREB (cAMP response element-binding protein).
|
44 |
20814220
|
Our data established that high glucose stimulated USF2 expression in HK-2 cells, at least in part, through angiotensin II-AT1-dependent activation of CREB, which can contribute to diabetic tubulointerstitial fibrosis.

|
Treatment of TR-iBRB2 cell with IGF-1 (100ng/ml for 0-24h) increases phosphorylation of (i) Akt Thr308, and its substrates including GSK-3? at Ser9, which inactivates its kinase function, and (ii) CREB at Ser133 (activation).
|

|
Based on these results, we propose that insulin/IGF-I act through IRS-1 phosphorylation to stimulate differentiation of brown preadipocytes via two complementary pathways: 1) the Ras-ERK1/2 pathway to activate CREB and 2) the phosphoinositide 3 kinase-Akt pathway to deactivate FoxO1.

We found that learning and memory level in the ghrelin treatment group improved significantly, expression of Bcl-xl, BDNF, CREB, p-CREB, and p-ERK1/2 in the hippocampus was increased in the ghrelin treatment group, and the number of apoptotic neurons in the hippocampus decreased remarkably.
|
51 |

|
We suggested that ghrelin improved cognitive ability in streptozotocin-induced diabetic rats by improving the expressions of BDNF and CREB and by attenuating hippocampus neuronal apoptosis.
