It is reported that apple polysaccharide can prevent colon cancer growth and impede colon cancer progression. Apple oligosaccharide was prepared by the combination of alkaline hydrolysis and enzymolysis of apple polysaccharides, and purified by anion column chromatography. The aim of this study is to explore the effect of apple oligosaccharide on the(More)
A simple and efficient method for selectively imaging and monitoring in situ the expression of sialylated glycoproteins on living cells has been developed. Treating living cells by mild periodate oxidation to selectively generate aldehydes on sialylated glycoproteins, followed by direct labeling of aldehydes with a commercially available fluorescent tag,(More)
Ag recognition and Ab production in B cells are major components of the humoral immune response. In the current study, we found that the core fucosylation catalyzed by α1,6-fucosyltransferase (Fut8) was required for the Ag recognition of BCR and the subsequent signal transduction. Moreover, compared with the 3-83 B cells, the coalescing of lipid rafts and(More)
OBJECTIVE To investigate the gene-expression profile of chronic obstructive pulmonary disease (COPD) patients and explore the possible therapeutic targets. METHODS The microarray raw dataset GSE29133, including three COPD samples and three normal samples, was obtained from Gene Expression Omnibus. After data preprocessing with the Affy package, Student's(More)
Along with the speedy development of tourism in the world, the multifaceted tourism impacts have been broadly recognized, which causes great interests and concerns as well to the academic community. Therefore, it is no surprising that nowadays tourism impact study becomes one of the most important research topics worldwide. This paper synthesizes the(More)
Mucin-type O-linked glycoproteins are known for regulating many aspects of cell activity but remains a challenge to detect under physiological conditions which is due to the diversity of O-glycosylation and the lack of universal method. Here a direct labeling strategy for in situ visualizing of mucin-type O-linked glycoproteins on living cells has been(More)
Glycosylation is one of the most common eukaryotic post-translational modifications, and aberrant glycosylation has been linked to many diseases. However, glycosylation and glycome analysis is a significantly challenging task. Although several lines of evidence have indicated that protein glycosylation is defective in Alzheimer's disease (AD), only a few(More)
N-glycans play important roles in various pathophysiological processes and can be used as clinical diagnosis markers. However, plasma N-glycans change and their pathophysiological significance in the setting of hypercholesterolemia, a major risk factor for atherosclerosis, is unknown. Here, we collected plasma from both hypercholesterolemic patients and(More)
