Methamphetamine (METH) abuse causes neurodegeneration. Medicinal herb such as crocin has neuroprotective properties. The current study evaluates the role of CREB-BDNF signaling pathway in mediating the neuroprotective effects of crocin against METH-induced neurodegeneration in rats. Sixty adult male rats were divided randomly into group 1 and group 2 which received 0.7 mL/rat ...

• IF 1 regulates MCU-dependent mitochondrial Ca 2+ uptake. loss induces MCU upregulation through activation of the AMPK/CREB pathway. OMA1 depletion restores physiological levels and entry.

Objective(s): Cyclic AMP (adenosine monophosphate) response element-binding protein (CREB) and Brain-derived neurotrophic factor (BDNF) are reported to broadly involve in learning capacity and memory. BDNF exerts its functions via tropomyosin receptor kinase B (TrkB). BDNF transcription is regulated by stimulating CREB phosphorylation. The CREB-TrkB-BDNF pathway is rep...

The aim of the present study was to examine the hypothesis that miR-33-5p attenuates morphine state-dependent (StD) memory via the µ opioid receptor by regulating cyclic AMP response element-binding protein (CREB). The effects of post-training morphine and morphine StD memory and their interaction with pre-test naloxone were evaluated using a single-trial inhibitory avoidance paradigm. Then, th...

Introduction: The neuroprotective impact of curcumin and the role of CREB (cyclic AMP response element binding protein)-BDNF (brain-derived neurotrophic factor) signaling pathway was evaluated in methamphetamine (METH)-induced neurodegeneration in rats. Methods: Sixty adult male rats were randomly divided into 6 groups. While normal saline and 10 mg/kg METH were administered intraperitoneally ...

Signaling through cAMP plays an important role in heart failure. Phosphorylation of cAMP response element binding protein (CREB) at serine-133 regulates gene expression in the heart. We examined the functional significance of CREB-S133 phosphorylation by comparing transgenic models in which a phosphorylation resistant CREB-S133A mutant containing either an intact or a mutated leucine zipper dom...

Objective(s): Neurodegeneration is an outcome of Methamphetamine (METH) abuse. Studies have emphasized on the neuroprotective properties of lithium. The current study is designed towards evaluating the role of Akt-1/GSK3 and CREB-BDNF signaling pathways in mediating lithium neuroprotection against METH-induced neurodegeneration in rats. Materials and ...

In this study, the effect of topiramate, as an antiepileptic drug, was evaluated on morphine craving in rats. The conditioned place preference (CPP) test was used for this purpose. Repeated administration of morphine (10 mg/kg, i.p. for 4 days) induced significant CPP. Administration of topiramate (50 and 100 mg/kg, i.p. for 4 days) with each morphine administration decreased the acquisition of...

Prevailing views of neurotrophin action hold that the transcription factor CREB is constitutively bound to target genes with transcriptional activation occurring via CREB phosphorylation. However, we report that within several CRE-containing genes, CREB is not constitutively bound. Upon exposure of neurons to brain-derived neurotrophic factor (BDNF), CREB becomes rapidly bound to DNA coincident...
