Amyloid plaques are crucial for the pathogenesis of Alzheimer disease (AD). Phagocytosis of fibrillar β-amyloid (Aβ) by activated microglia is essential for Aβ clearance in Alzheimer disease. However, the mechanism underlying Aβ clearance in the microglia remains unclear. In this study, we performed stable isotope labeling of amino acids in cultured cells(More)
Commercially pure titanium (cpTi) and polyetheretherketone (PEEK) are widely used surface-modified implant materials in orthopedics and dental therapeutics. However, there still has not been comprehensive biocompatibility evaluation of them at molecular level. By employing stable isotope labeling with amino acids in cell culture (SILAC), we profiled the(More)
Amyloid-beta (Aβ) aggregation plays an important role in the development of Alzheimer's disease (AD). In the AD brain, amyloid plaques are surrounded by reactive astrocytes, and many essential functions of astrocytes have been reported to be mediated by protein secretion. However, the roles of activated astrocytes in AD progression are under intense debate.(More)
Oxidative stress plays a pivotal role in normal brain aging and various neurodegenerative diseases, including Alzheimer's disease (AD). Irreversible protein carbonylation, a widely used marker for oxidative stress, rises during aging. The temporal cortex is essential for learning and memory and particularly susceptible to oxidative stress during aging and(More)
UNLABELLED Amyloid-beta (Aβ) deposition plays a crucial role in the progression of Alzheimer's disease (AD). The Aβ deposited extracellularly can be phagocytosed and degraded by surrounding activated astrocytes, but the precise mechanisms underlying Aβ clearance mediated by astrocytes remain unclear. In this study, we performed tandem mass tag-based(More)
Neuroblastoma is the most common pediatric extracranial solid tumor with a broad spectrum of clinical behavior and poor prognosis. Despite intensive multimodal therapy, ongoing clinical trials, and basic science investigations, neuroblastoma remains a complex medical challenge with a long-term survival rate less than 40%. In our study, we found that(More)
Deregulation of the TH17 subset of helper T cells is closely linked with immunological disorders and inflammatory diseases. However, the mechanism by which TH17 cells are regulated remains elusive. Here we found that the phosphatase DUSP2 (PAC1) negatively regulated the development of TH17 cells. DUSP2 was directly associated with the signal transducer and(More)
PTEN is a tumor suppressor frequently mutated in human cancers. PTEN inhibits the phosphatidylinositol 3-kinase (PI3K)-AKT cascade, and nuclear PTEN guards the genome by multiple mechanisms. Here, we report that PTEN physically associates with the minichromosome maintenance complex component 2 (MCM2), which is essential for DNA replication. Specifically,(More)
The information in rural areas of Shijiazhuang survey results showed that there were greater differences between urban and rural areas in the information equipment ownership and consumption of information, the way of farmers understanding information was rather narrow and concentrated. The information gap existed between urban and rural areas. This paper(More)
EG5 (KIF11) is a member of the kinesin-like protein family involved in centrosome separation and bipolar spindle formation. When a cell enters mitosis, CDK1 phosphorylates EG5 at Thr926 and promotes EG5 localization on the mitotic spindle which drives bipolar spindle formation. EG5 provides power for spindle movement and thus controls the dynamics of(More)
