Chronic Estradiol Administration During the Early Stage of Alzheimer's Disease Pathology Rescues Adult Hippocampal Neurogenesis and Ameliorates Cognitive Deficits in Aβ Mice.

Alzheimer's disease (AD) is the leading cause of dementia and has become an important public health concern. Accumulating evidence indicates that estradiol can both facilitate and impair memory-related processes and, as a result, the precise nature of the role that estradiol plays during AD pathology remains elusive. Therefore, the present study established a mouse model of AD using stereotactic brain injection of Aβ in which the mice were bilaterally ovariectomized to investigate the effects of 17β-estradiol (E2) treatment during different stages of the AD process (early and late stages).

SNCA rs3822086 C>T Polymorphism Increases the Susceptibility to Parkinson's Disease in a Chinese Han Population.

Objective: Protofibrils of alpha-synuclein mediate neuronal cell death and propagate Parkinson's disease (PD). In this study, we investigated the relationship between the rs3822086 C>T polymorphism located in the fourth intron of the alpha-synuclein (SNCA) gene and susceptibility to PD in a Chinese Han population.

Methods: 146 PD patients and 144 sex- and age-matched healthy individuals (control group) were selected for this study.

Change of MicroRNA-134, CREB and p-CREB expression in epileptic rat.

Objective: To To investigate the changes of MicroRNA-134, CREB and p-CREB expression in epileptic rat brains in order to elucidate the molecular mechanisms of epilepsy, providing new ideas for clinical treatment.

Methods: Sixty-four Spraque-Dawley (SD) rats were divided into groups randomly, including control group, six hours after seizure group, 24-hour group, three-day group, one-week group, two-week group, four-week group, and eight-week group. All groups were placed under a pilocarpine-induced epilepsy model except the control group, and all rats were decapitated in different points of time.

Estradiol prevents Aβ 25 35-inhibited long-term potentiation induction through enhancing survival of newborn neurons in the dentate gyrus.

Aim And Methods: Estradiol (E2) is reported to attenuate β-amyloid (Aβ) accumulation and slow the progression of Alzheimer's disease (AD). This study explored the beneficial effect of E2 in AD using histological examination and electrophysiological recording technique in AD model mice created by intracerebroventricular injection of β-amyloid 25-35 (Aβ 25-35).

Results: Infusion of Aβ 25-35 reduced the number of newborn neurons in the 2nd week after birth, a critical period for neurite growth, and impaired high-frequency stimulation-dependent long-term potentiation (LTP) induction in perforant path-granular synapses of hippocampal dentate gyrus (DG).

Electroencephalogram global field synchronization analysis: a new method for assessing the progress of cognitive decline in Alzheimer's disease.

Alzheimer's disease (AD) is the most common cause of dementia. Global field synchronization (GFS) can measure functional synchronization in frequency-domain electroencephalogram (EEG) data. The aim of this study is to explore GFS values and its clinical significance for severity of cognitive decline in AD.

Selenoprotein S expression in the rat brain following focal cerebral ischemia.

Recent studies on cerebral ischemic stroke have demonstrated the importance of the inflammatory response. Ongoing inflammatory insults have been implicated as a secondary mechanism underlying neuronal injury induced by ischemia, and anti-inflammatory strategies have gained considerable interest. Selenoprotein S (SelS), which is an endoplasmic reticulum resident protein, is known to promote cell survival by regulating inflammation.

Increased expression of annexin A7 in temporal lobe tissue of patients with refractory epilepsy.

Annexin A7 is a member of the family of annexins, which are thought to function in the regulation of calcium homeostasis and the fusion of vesicles. Refractory epilepsy may be related to the imbalance of calcium homeostasis. Our aims are to investigate the expression of Annexin A7 in epileptic brains in comparison with human controls and to explore Annexin A7's possible role in refractory epilepsy.

Downregulation of gephyrin in temporal lobe epilepsy neurons in humans and a rat model.

Gephyrin, which is a postsynaptic scaffolding protein participated in clustering GABA(A) receptors at inhibitory synapses, has been reported to be involved in temporal lobe epilepsy (TLE) recently. Here, we investigate gephyrin protein expression in the temporal lobe epileptic foci in epileptic patients and experimental animals in order to explore the probable relationship between gephyrin expression and TLE. Using immunohistochemistry, immunofluorescence, and western blot analysis, gephyrin expression was examined in 30 human temporal neocortex samples from patients who underwent surgery to treat drug-refractory TLE and 10 histological normal temporal neocortex from the controls.

Expression and localization of annexin A7 in the rat lithium-pilocarpine model of acquired epilepsy.

Background: Annexin A7 (synexin, ANXA7) is a member of annexins, which plays an essential role in the regulation of calcium homeostasis. Considerable evidence shows that the pathogenetic mechanism of acquired epilepsy (AE) has been related to the imbalance of calcium homeostasis. The aim of this study was to investigate ANXA7 expression and cellular localization in the cortex and hippocampus in the rat lithium-pilocarpine model of AE.

Signals in pathological CNS extracts of ALS mice promote hMSCs neurogenic differentiation in vitro.

The capability of MSCs to differentiate into neurons has been proven by many studies. Recently, other studies have cast doubt on MSCs neurogenic differentiation with non-physiological chemical inducing agents in vitro. This present study was designed to use conditioned medium to investigate whether signals from pathological condition of ALS were competent to induce a program of neurogenic differentiation in expanded cultures of hMSCs.

Translocation and neuroprotective properties of transactivator-of-transcription protein-transduction domain-neuroglobin fusion protein in primary cultured cortical neurons.

Ngb (neuroglobin) is a newly discovered hexaco-ordinate globin that is expressed in vertebrate brain and peripheral nervous systems. Expression of Ngb increases in response to oxygen deprivation and protects neurons from hypoxia in vitro and in vivo. However, the lack of its transduction ability into cells resulted in limited neuroprotection.
