Mesenchymal stem cells (MSCs) have been successfully used for the treatment of experimental stroke. However, the neurorestorative mechanisms by which MSCs improve neurological functional recovery are not fully understood. Endogenous cell proliferation in the subventricular zone (SVZ) after stroke is well known, but most of newly formed cells underwent(More)
Growing evidence from rodent models of temporal lobe epilepsy (TLE) indicates that dysregulation of the mammalian target of rapamycin (mTOR) pathway is involved in seizures and epileptogenesis. However, the role of the mTOR pathway in the epileptogenic process remains poorly understood. Here, we used an animal model of TLE and sclerotic hippocampus from(More)
Tenascin (TN) is an extracellular oligomeric glycoprotein that participates in the adhesion of cells to extracellular matrixc (ECM). Studies have shown that the expression levels of TN are upregulated in a variety of cancers, including colon cancer, lung cancer, brain tumor, and breast cancer. However, the implications and utilities of TN in clinical(More)
Notch signaling in the nervous system is often regarded as a developmental pathway. However, recent studies have suggested that Notch is associated with neuronal discharges. Here, focusing on temporal lobe epilepsy, we found that Notch signaling was activated in the kainic acid (KA)-induced epilepsy model and in human epileptogenic tissues. Using an acute(More)
The McCune-Albright syndrome (MAS) is characterized by a clinical triad of polyostotic fibrous dysplasia, café-au-lait hyperpigmented macules, and hypersecretory endocrinopathies. Acromegaly is an uncommon manifestation of the endocrine disturbance associated with MAS, and the role of surgery in managing these cases has been a topic of debate. The authors(More)
Most gene transfer studies conducted in the central nervous system (CNS) with recombinant adeno-associated virus (rAAV) vectors have been carried out by direct intra-parenchymal injection. However, this delivery method usually results in transduction of cells in only a limited region and is quite invasive, which may hamper its potential clinical(More)
OBJECTIVE To examine the effects of intraventricular pre-treatment with recombinant adeno-associated virus vectors encoding VEGF (rAAV-VEGF) on early stroke in a rat model of transient middle cerebral artery occlusion (tMCAO). METHODS rAAV-VEGF, rAAV-null or physiologic saline was delivered into the lateral ventricle of 93 Wistar rats, respectively. Eight(More)
INTRODUCTION Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive genetic disease that leads to extrapyramidal symptoms, such as dystonia, ataxia, dysarthria, and involuntary movements. Treatment of PKAN with deep brain stimulation (DBS) has been reported, but mainly focuses on targeting the globus pallidus internus (GPi).(More)
In central nervous system, schwannomas, as ubiquitous tumors, mostly originate from sensory nerves like auditory and trigeminal nerves. However, intrasellar schwannomas are extremely rare. They are often misdiagnosed as pituitary adenomas. We report a rare case of schwannoma in the sellar region--a challenging diagnosis guided by clinical presentations,(More)
The hippocampus appears commonly affected by aging and various neurologic disorders in humans, whereas little is known about age-related change in overall protein expression in this brain structure. Using the 4-plex tandem mass tag labeling, we carried out a quantitative proteomic study of the hippocampus during normal aging using postmortem brains from(More)
