#1
Bo Young Choi, Dae Ki Hong, Sang Won Suh
Our previous study demonstrated that colchicine-induced dentate granule cell death is caused by blocking axonal flow and the accumulation of intracellular zinc. Zinc is concentrated in the synaptic vesicles via zinc transporter 3 (ZnT3), which facilitates zinc transport from the cytosol into the synaptic vesicles. The aim of the present study was to identify the role of ZnT3 gene deletion on colchicine-induced dentate granule cell death. The present study used young (3-5 months) mice of the wild-type (WT) or the ZnT3(-)(/)(-) genotype...

MiR-126, a microRNA implicated in blood vessel integrity, angiogenesis and vascular inflammation, is markedly decreased in the sera of patients with intracerebral hemorrhage (ICH). The current study aims to evaluate the potential therapeutic effect of miR-126-3p on brain injuries in a rat model of collagenase-induced ICH. Intracerebroventricular administration of a miR-126-3p mimic significantly alleviated behavioral defects 24 h after ICH, as examined by paw placement and corner tests. ICH led to increased blood-brain barrier (BBB) permeability and cerebral edema, both of which were attenuated by miR-126-3p mimic...

Neuronal apoptosis is considered to be a crucial therapeutic target against early brain injury (EBI) after subarachnoid hemorrhage (SAH). Emerging evidence indicates that Exendin-4 (Ex-4), a glucagon-like peptide 1 receptor (GLP-1R) agonist, plays a neuroprotective role in cerebrovascular disease. This study was conducted in order to verify the neuroprotective role of EX-4 in EBI after SAH in rats. The endovascular perforation model of SAH was performed in Sprague-Dawley rats (n = 153). Ex-4 was intraperitoneally injected 1 h after SAH induction in the rats (SAH + Ex-4)...

OBJECTIVES: Coenzyme Q10 (CoQ10, ubiquinone) stands among the safest supplements in the elderly to protect against cardiovascular disorders. Noteworthy, CoQ10 deficiency is common in many surviving stroke patients as they are mostly prescribed statins for the secondary prevention of stroke incidence lifelong. Accordingly, the current study aims to experimentally examine whether CoQ10 supplementation in animals receiving atorvastatin may affect acute stroke-induced injury. METHODS: Adult rats underwent transient middle cerebral artery occlusion after atorvastatin pretreatment (5 or 10 mg/ kg/day; po; 30 days) with or without CoQ10 (200 mg/kg/day)...

Convulsive seizure is known to be associated with hippocampal abnormalities, such as hilar cell degeneration, abnormal mossy fiber sprouting in the dentate gyrus (DG) and abnormal expression of immediate early genes. However, whether these morphological changes are a cause or consequence of convulsive seizures has remained contentious. Zitter (zi/zi) rats carry a mutation of the attractin gene and display spongiform degeneration of the brain. Spontaneous convulsive seizures in zi/zi rats over 8 months (M) old were demonstrated using 24-h video monitoring...

BACKGROUND: Elevated plasma homocysteine (Hcy) levels have been indicated as a strong and modifiable risk factor of ischemic stroke; the previous studies have shown that exposure to Hcy activates cultured microglia. However, whether neurotoxicity of Hcy involves microglia activation following brain ischemia and the underlying mechanisms remains incompletely understood. METHODS: The cerebral damage was evaluated by staining with 2,3,5-triphenyltetrazolium chloride, hematoxylin-eosin, and Fluoro Jade B...

BACKGROUND: The brain is exposed to many excitotoxic insults that can lead to neuronal damage. Among these, Epilepsy is a neurological disease that affects a large percentage of world population and is commonly associated with cognitive disorders and excitotoxic neuronal death. Most experimental strategies are focused on preventing Status Epilepticus (SE), but once it has already occurred, the key question is whether it is possible to save neurons. PURPOSE: The aim of this study was to determine if a purified alkaloid extract (AE) obtained from Phlegmariurus saururus, a genus of Lycophyte plants (sometimes known as firmossesor fir club mosses) could induce neuroprotection following SE...

Traumatic brain injury (TBI) produces profound and lasting neuroinflammation that has both beneficial and detrimental effects. Recent evidence has implicated microRNAs (miRNAs) in the regulation of inflammation both in the periphery and the CNS. We examined the expression of inflammation associated miRNAs in the context of TBI using a mouse controlled cortical impact (CCI) model and found increased levels of miR-21, miR-223 and miR-155 in the hippocampus after CCI. The expression of miR-155 was elevated 9-fold after CCI, an increase confirmed by in situ hybridization (ISH)...

OBJECTIVES: Rufinamide, a voltage-gated sodium channel (VGSC) blocker, is widely used for the clinical treatment of seizures associated with Lennox-Gastaut syndrome. Previous studies have demonstrated that VGSC blockers have neuroprotective properties against ischemic damage following experimental cerebral ischemia. However, protective effects of rufinamide against cerebral ischemic insults have not been addressed. Therefore, in the present study, we firstly examined neuroprotective effects of rufinamide using a gerbil model of transient global cerebral ischemia...

Perinatal hypoxic-ischemic reperfusion (I/R)-related brain injury is a leading cause of neurologic morbidity and life-long disability in children. Infants exposed to I/R brain injury develop long-term cognitive and behavioral deficits, placing a large burden on parents and society. Therapeutic strategies are currently not available for infants with I/R brain damage, except for hypothermia, which can only be used in full term infants with hypoxic-ischemic encephalopathy (HIE). Moreover, hypothermia is only partially protective...

Neonatal hypoxic-ischemic brain damage (HIBD) is one of the leading causes of neonatal mortality and permanent neurological disability worldwide and the effective treatment strategies are not yet available. It has been demonstrated that Chitosan oligosaccharide (COS) exerts protective effect in vitro ischemic brain injury. However, no information is available on possible effects of COS on neonatal HIBD. To investigate the hypothesis of the potential neuroprotective effect of COS on the brain injury due to HIBD, 7-day-old Sprague-Dawley rats were treated with left carotid artery ligation followed by exposure to 8% oxygen (balanced with nitrogen) for 2...

Cell signaling mediated by P2X7 receptors (P2X7R) has been suggested to be involved in epileptogenesis, via modulation of intracellular calcium levels, excitotoxicity, activation of inflammatory cascades, and cell death, among other mechanisms. These processes have been described to be involved in pilocarpine-induced status epilepticus (SE) and contribute to hyperexcitability, resulting in spontaneous and recurrent seizures. Here, we aimed to investigate the role of P2X7R in epileptogenesis in vivo using RNA interference (RNAi) to inhibit the expression of this receptor...

Traumatic brain injury (TBI) is a public health concern, and causes cognitive dysfunction, emotional disorders, and neurodegeration, as well. The currently available treatments are all symptom-oriented with unsatifying efficacy. It is highly demanded to understand its underlying mechanisms. Controlled cortical impact (CCI) was used to induce TBI in aged female mice subjected to ovariectomy. Brain damages were assessed with neurological severity score, brain infarction and edema. Morris water maze and elevated plus maze were applied to evaluate the levels of anxiety...
