The previous study indicated that DHCR24/seladin-1 was an important neuroprotective effector. However, the molecular mechanisms that androgen modulates the expression of seladin-1 remain incompletely defined. In this paper, we showed that the expression of seladin-1 was significantly increased by testosterone at all concentrations tested at the protein and(More)
Previous evidences indicate that androgen is neuroprotective in the brain. However, the underling mechanisms remain to be fully elucidated. Moreover, it is controversial whether dihydrotestosterone (DHT) modulates the expression of apoptosis-related effectors, such as survivin, XIAP, bax, and bcl-xl proteins mediated by the PI3-K/Akt pathway, which(More)
Neurodegenerative disorders are chronic and progressive disease. Exendin-4 (Ex-4) can function as a neuroprotective agent and has novel therapeutic ability for the treatment of neurodegenerative disorders. In this study, we aimed to explore the neuroprotective effect of Ex-4 on PC12 cell apoptosis induced by Aβ25-35 in molecular level. The apoptosis of PC12(More)
Anxiety disorders are frequently comorbid with insomnia, and sleep disturbance in patients with anxiety disorders is the most common complaint. Antidepressants can affect sleep quality; however, their effect in patients with comorbid insomnia and anxiety disorders is unclear. The aim of the present study was to comprehensively evaluate the dose, treatment(More)
Insulin-like growth factor-1 (IGF-1) shows protective effect against Aβ-induced cytotoxicity and apoptosis, but the underlying mechanisms are poorly characterized. The present study was conducted to explore the mechanisms involved in the beneficial effect of IGF-1 against Aβ-induced apoptosis in SH-SY5Y cells. We found that pretreatment with IGF-1(More)
BACKGROUND AND PURPOSE The level of stress hormones, especially cortisol reflects stroke severity and acts as an early risk assessment of the severity of disease and prognosis. There are few neuroendocrine change and prognostic value data in patients with spontaneous supratentorial intracerebral hemorrhage (ICH). The present study aimed to evaluate the(More)
BACKGROUND/AIMS Neuroinflammation mediated by activated microglia may play a pivotal role in a variety of central nervous system (CNS) pathologic conditions, including ethanol-induced neurotoxicity. The purpose of this study was to investigate the function of Tβ4 in ethanol-induced microglia activation. METHODS Quantitative real-time PCR was conducted to(More)
OBJECTIVE To observe the effect of pregnenolone (PREG) intervention on the cholinergic system function and the synaptic protein 1 (SYP1) expression in different brain regions of aged rats. METHOD Twenty-four-month-old male Sprague Dawley rats intraperitoneally injected every other day for one month were divided into blank control group, solvent control(More)
Alzheimer's disease (AD) is the most common type of dementia and has no effective therapies. Previous studies showed that bone morphogenetic protein 9 (BMP9), an important factor in the differentiation and phenotype maintenance of cholinergic neurons, ameliorated the cholinergic defects resulting from amyloid deposition. These findings suggest that BMP9 has(More)
