Lung cancer is the leading cause of cancer deaths worldwide. Recent advances in targeted therapies hold promise for the development of new treatments for certain subsets of cancer patients by targeting specific signaling molecule. Based on the identification of the transcription factor cyclic AMP response element-binding protein (CREB) as an important regulator of growth of several types of can...
The human α1A voltage-dependent calcium channel (Cav2.1) is a pore-forming essential subunit embedded in the plasma membrane. Its cytoplasmic carboxyl(C)-tail contains a small poly-glutamine (Q) tract, whose length is normally 4∼19 Q, but when expanded up to 20∼33Q, the tract causes an autosomal-dominant neurodegenerative disorder, spinocerebellar ataxia type 6 (SCA6). A recent study has shown ...
Purpose: To investigate the effect of puerarin on symptoms depression in ovariectomized female rat model, and mechanism action involved.
 Methods: Ninety healthy Sprague Dawley (SD) rats were assigned to five groups: sham, low-dose puerarin, medium-dose high-dose groups, with 18 per group. Changes levels dopamine (DA), norepinephrine (NA), 5-hydroxytryptamine (5-HT), apoptosis-related prot...
The induction of long-term potentiation and depression (LTP and LTD) is thought to trigger gene expression and protein synthesis, leading to consolidation of synaptic and neuronal changes. However, while LTP and LTD have been proposed to play important roles for sensori-motor learning in the cerebellum granular layer, their association with these mechanisms remained unclear. Here, we have inves...
Experimental evidence indicates that chemical stimulation of lateral hypothalamus (LH) by carbachol can produce conditioned place preference (CPP) in rats. Several lines of evidence have shown that cAMP-response element binding protein (CREB), extracellular signal-regulated kinase (ERK), and c-fos have pivotal role in CPP induced by drugs of abuse, such as morphine, cocaine, nicotine, and alcoh...
Antidepressant activity of crocin, saffron main component, has been established before. Based on previous study, it is suggested that elevation in the levels of BDNF (brain-derived neurotrophic factor), CREB (cAMP response element binding) and VGF neuropeptide could be considered as one probable molecular mechanisms involved in antidepressant activity of long term crocin administration in the r...
The aim of this study was to investigate whether an excitotoxic concentration of N-methyl-D-aspartate (NMDA) increases the expression of the phosphorylated cAMP response element-binding protein (p-CREB) and the DNA-binding activity of the cAMP response element (CRE) in rat retina. Intravitreal injection of NMDA was performed in adult male Wistar rats. p-CREB protein levels in the retina were ex...
BACKGROUND AND PURPOSE White matter lesions contribute to cognitive impairment in poststroke patients. The present study was designed to assess the neuroprotective mechanisms of cilostazol, a potent inhibitor of type III phosphodiesterase, through signaling pathways that lead to activation of transcription factor cAMP-responsive element binding protein (CREB) phosphorylation using rat chronic c...
Fetal alcohol syndrome (FAS) is a developmental neuropathology resulting from in utero exposure to ethanol; many of ethanol's effects are likely to be mediated by the neurotransmitter γ-aminobutyric acid (GABA). We studied modulation of the neurotransmitter receptor GABA(B)R and its capacity for intracellular signal transduction under conditions of ethanol treatment (ET) and RNA interference to...
BACKGROUND There are numerous studies implicating that EphB receptors and ephrinB ligands play important roles in modulating the transduction of spinal nociceptive information. EphrinB-EphB signaling may contribute to hyperalgesia via various kinds of downstream molecules, the mechanisms of which have not been completely understood. OBJECTIVE The aim of the present study was to identify wheth...
