Thus CaMKIV mediated phosphorylation of CREB may be a major mediator of this consolidation, in part through enhancement of local slow delta oscillations during NREM sleep. | |||||||||||||||
| |||||||||||||||
|
CaMKIV phosphorylates CREB at a particular residue, serine 133 (Ser133), and phosphorylation of Ser133 is required for CREB-mediated transcription [29]. | |||||||||||||||
| |||||||||||||||
|
CaMKIV phosphorylates CREB and the phosphorylation is terminated by calcineurin, possibly through direct CREB dephosphorylation or through activation of the downstream protein phosphatase 1 [19]. | |||||||||||||||
| |||||||||||||||
|
Second, it has been demonstrated that CaMKIV phosphorylates and regulates the function of synaptic proteins including the actin binding protein synapsin I [35] and the microtubule regulator Stathmin [36]. | |||||||||||||||
| |||||||||||||||
|
The nuclear location of CaMKIV, its ability to phosphorylate CREB and its broad expression throughout forebrains areas suggests that CaMKIV may play an important role in higher brain function. | |||||||||||||||
| |||||||||||||||
|
CaMKIV is a serine-threonine kinase and is activated by a combination of elevated intracellular Ca2+ and CaMK kinase during neuronal activity [for review, see [25] and phosphorylates CREB [26,27]]. | |||||||||||||||
| |||||||||||||||
|
It has been well established that the cyclic AMP-responsive element binding protein (CREB) is a major transcription factor associated with long-term memory [12,13], and calcium-calmodulin-dependent protein kinase IV (CaMKIV) plays an essential role in activity-dependent CREB phosphorylation [14-16]. | |||||||||||||||
| |||||||||||||||
|
The CMS procedure inhibited hippocampal protein kinase A (PKA) activity, extracellular signal-regulated kinases (ERK1/2), and calcium/calmodulin-dependent protein kinase IV (CaMKIV) phosphorylation in AQP4(+/+) and AQP4(-/-) mice. | |||||||||||||||
| |||||||||||||||
|
However, fluoxetine restored CMS-induced inhibition of hippocampal CaMKIV phosphorylation in AQP4(+/+) mice but failed in AQP4(-/-) mice. | |||||||||||||||
| |||||||||||||||
|
This is the first evidence to suggest that the increased CREB phosphorylation via CaMKIV signal pathway in hippocampus is relevant to opioids psychological dependence. | |||||||||||||||
| |||||||||||||||
|
Thus, it appears that CaMKIV, a key upstream molecule which phosphorylates CREB [26], can modulate the expression of slow delta oscillations as a consequence of learning. | |||||||||||||||
| |||||||||||||||
|
CaMKIV plays a role in the activity-dependent phosphorylation of CREB, which regulates the expression of genes involved in neuroplasticity [24], learning and memory [25], [26], and emotional behaviors [27], [28]. | |||||||||||||||
| |||||||||||||||
|
cAMP response-element binding protein (CREB), a transcription factor involved in learning, memory and drug addiction, is phosphorylated by calcium-calmodulin-dependent protein kinase IV (CaMKIV). | |||||||||||||||

| |||||||||||||||
|
F9203, which could not induce CPP, failed to increase the CREB phosphorylation and the colocalization of P-CREB with CaMKIV both in hippocampus from CPP mice and in cultured hippocampal neurons. | |||||||||||||||
| |||||||||||||||
|
Calcineurin directly dephosphorylates and inactivates CaMKIV [18]. | |||||||||||||||
| |||||||||||||||
|
To better understand the role of CREB in opioids dependence and underlying signal pathways, we compared the effects of three ohmfentanyl stereoisomers ((-)-cis-(3R,4S,2'R) OMF (F9202), (+)-cis-(3R,4S,2'S) OMF (F9204), (-)-cis-(3S,4S,2'R) OMF (F9203)) and morphine on CREB phosphorylation and the expression of Ca2+/calmodulin-dependent protein kinase IV (CaMKIV) in hippocampus derived from mice which displayed conditioned place preference (CPP) behavior by Western blot, and immunohistochemistry analyses. | |||||||||||||||

| |||||||||||||||
|
The results showed that F9202, F9204 or morphine, which could induce CPP, enhanced CREB phosphorylation and the expression of CaMKIV in hippocampus from CPP mice without affecting total CREB protein level. | |||||||||||||||
