A number of therapeutic strategies for treating Alzheimer's disease have focused on reducing amyloid burden in the brain. Among these approaches, the expression of amyloid beta peptide (Abeta)-degrading enzymes in the brain has been shown to be effective but to date not practical for treating patients. We report here a novel strategy for lowering amyloid(More)
The advanced medium-throughput NanoString nCounter technology has been increasingly used for mRNA or miRNA differential expression (DE) studies due to its advantages including direct measurement of molecule expression levels without amplification, digital readout and superior applicability to formalin fixed paraffin embedded samples. However, the analysis(More)
It is generally believed that amyloid beta peptides (Abeta) are the key mediators of Alzheimer's disease. Therapeutic interventions have been directed toward impairing the synthesis or accelerating the clearance of Abeta. An equilibrium between blood and brain Abeta exists mediated by carriers that transport Abeta across the blood-brain barrier. Passive(More)
β-Secretase, the rate-limiting enzymatic activity in the production of the amyloid-β (Aβ) peptide, is a major target of Alzheimer's disease (AD) therapeutics. There are two forms of the enzyme: β-site Aβ precursor protein cleaving enzyme (BACE) 1 and BACE2. Although BACE1 increases in late-stage AD, little is known about BACE2. We conducted a detailed(More)
IDH1 mutations in gliomas associate with longer survival. Prooxidant and antiproliferative effects of IDH1 mutations and its d-2-hydroxyglutarate (2-HG) product have been described in vitro, but inconsistently observed. It is also unclear whether overexpression of mutant IDH1 in wild-type cells accurately phenocopies the effects of endogenous IDH1-mutations(More)
Neprilysin (NEP) is a zinc metallopeptidase that efficiently degrades the amyloid beta (Abeta) peptides believed to be involved in the etiology of Alzheimer disease (AD). The focus of this study was to develop a new and tractable therapeutic approach for treating AD using NEP gene therapy. We have introduced adeno-associated virus (AAV) expressing the mouse(More)
Prostate apoptosis response-4 (Par-4) is an endogenous tumor suppressor that selectively induces apoptosis in a variety of cancers. Although it has been the subject of intensive research in other cancers, less is known about its significance in gliomas, including whether it is regulated by key driver mutations, has therapeutic potential against glioma stem(More)
Mutant isocitrate dehydrogenase 1 (IDH1) is common in gliomas, and produces D-2-hydroxyglutarate (D-2-HG). The full effects of IDH1 mutations on glioma biology and tumor microenvironment are unknown. We analyzed a discovery cohort of 169 World Health Organization (WHO) grade II–IV gliomas, followed by a validation cohort of 148 cases, for IDH1 mutations,(More)
Monoclonal antibodies (mAb) directed against CD20, either unmodified or in radiolabeled forms, have been successfully used in clinic as effective therapeutic agents in the management of non-Hodgkin's B-cell lymphoma. Despite all clinical success the exact mechanisms of action of various anti-CD20 antibodies remains mostly unclear. Several mechanisms have(More)
The scale of the modern city has been expanding, which leads to a lot of serious environmental pollution problems. Among them, the air pollution problem is the most prominent. In order to control the air pollution in urban cities, the government has deployed a lot of air pollutant monitoring equipment which produce massive multi-dimensional time series(More)
