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)
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)
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)
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)
Microglia play a pivotal role in clearance of Aβ by degrading them in lysosomes, countering amyloid plaque pathogenesis in Alzheimer’s disease (AD). Recent evidence suggests that lysosomal dysfunction leads to insufficient elimination of toxic protein aggregates. We tested whether enhancing lysosomal function with transcription factor EB (TFEB), an(More)
PTEN is a critical tumour suppressor that is frequently mutated in human cancer. We have previously identified a CUG initiated PTEN isoform designated PTENα, which functions in mitochondrial bioenergetics. Here we report the identification of another N-terminal extended PTEN isoform, designated PTENβ. PTENβ translation is initiated from an AUU codon(More)
Constructed wetland, one of technologies of wastewater treatment, is developing recently. There are many advantages for this technology: high removal capacity, simple technology of construction operation and maintenance, and low costs in investment, maintenance and operation. Therefore it is adapted to sewage treatment of village and small town short of(More)
Hypoxia-inducible factor 2α (HIF2α) plays critical roles in cancer progression. Although the mechanisms of HIF2α translation and degradation have been well studied, the mechanism for HIF2α regulation at transcriptional level is still not fully understood. Here, we present evidence that DNA methylation in promoter contributes to transcription of EPAS1 coding(More)
Diabetic nephropathy has a high cardiovascular risk with a low-level HDL(high density lipoprotein) in epidemiologic studies. Glycated HDL in diabetes can diminish the capacity to stimulate endothelial cell migration, but the mechanism has not been adequately explored in diabetic nephropathy. We performed this study to find out whether HDL in diabetic(More)
