Introduction: Bisphenol A (BPA) is a toxic chemical that is used as a monomer in the production of plastic products. The BPA has an endocrine-disrupting effect and ‎induces damage to the nervous system. Crocin, an active ingredient of Crocus sativus L. has ‎neuroprotective effects. Therefore, this study aimed to evaluate crocin’s effects on BPA-induced ‎memory impairment in rats and the levels ...

Long-term potentiation (LTP) is a form of activity dependent plasticity that induced by high-frequency stimulation or theta burst stimulation and results in synaptic transmission. Several Studies have been shown that LTP is one of the most important processes in the CNS that plays an important role in learning and memory formation. Ca2+/calmodulin-dependent protein kinase II (CaMKII) is a major...

Vincristine (VCR), an alkaloid isolated from vinca, is a commonly used chemotherapeutic drug. However, VCR therapy can lead to dose-dependent peripheral neurotoxicity, mainly manifesting as neuropathic pain, which one of the dominant reasons for limiting its utility. Experimentally, we discovered that VCR-induced pain (VINP) was accompanied by astrocyte activation; upregulation phospho-CaMKII (...

Abstract Pressure overload-induced cardiac hypertrophy is a maladaptive response with poor outcomes and limited treatment options. The transient receptor potential melastatin 4 (TRPM4) ion channel key to activation of Ca 2+ /calmodulin-dependent kinase II (CaMKII)-reliant hypertrophic signaling pathway after pressure overload, but TRPM4 neither stretch-activated nor -permeable. Here we show tha...

To examine the role of Ca2+/calmodulin-dependent protein kinase II (CaMKII) in cell differentiation and neuronal functions, stable transformants of PC12 cells were established that expressed levels of the alpha-subunit of CaMKII (alpha CaMKII) equivalent to mammalian neurons. The expression of the transfected alpha CaMKII gene or the endogenous beta CaMKII gene was monitored by RNase protection...

In a continuing search for proteins that target calcium/calmodulin-dependent protein kinase II (CaMKII) to postsynaptic density (PSD) substrates important in synaptic plasticity, we showed that the PSD protein densin-180 binds CaMKII. Four putative splice variants (A-D) of the cytosolic tail of densin-180 are shown to be differentially expressed during brain development. Densin-180 splicing aff...

One of the important targets of dopamine D4 receptors in prefrontal cortex (PFC) is the multifunctional Ca2+/calmodulin-dependent protein kinase II (CaMKII). In the present study, we investigated the effect of D4 receptor activation on subcellular localization of CaMKII. We found that activation of D4 receptors, but not D2 receptors, induced a rapid translocation of alpha-CaMKII from cytosol to...
