Many uncertainties remain regarding the physiological function of the prion protein PrP and the consequences of its conversion into the pathological scrapie isoform in prion diseases. Here, we show for the first time that different signal transduction pathways are involved in neurite outgrowth and neuronal survival elicited by PrP in cell culture of primary(More)
Diabetes increases the risk of cardiovascular diseases. Berberine (BBR), an isoquinoline alkaloid used in Chinese medicine, exerts anti-diabetic effect by lowering blood glucose and regulating lipid metabolism. It has been reported that BBR decreases mortality in patients with chronic congestive heart failure. However, the molecular mechanisms of these(More)
OBJECTIVE The aim of this study was to investigate the prevalence of gestational diabetes mellitus (GDM) and risk factors for the development of GDM in pregnant women in Tianjin, China, where the prevalence of GDM is still unknown. STUDY DESIGN AND METHODS A total of 9,471 pregnant women living in the six urban districts of Tianjin, China, took part in(More)
OBJECTIVE We compared the increases in the prevalence of gestational diabetes mellitus (GDM) based on the 1999 World Health Organization (WHO) criteria and its risk factors in Tianjin, China, over a 12-year period. We also examined the changes in the prevalence using the criteria of International Association of Diabetes and Pregnancy Study Group (IADPSG).(More)
The neural cell adhesion molecule L1 plays important roles in cell adhesion, neuronal migration, neurite outgrowth, fasciculation and pathfinding, neuronal survival, and synaptic plasticity. Many of these functions have been identified and characterized by using antibodies. Because of the need for reproducible and functionally active antibodies, we have(More)
Proteomic techniques are promising strategies in the surveillance of hepatocellular carcinoma (HCC). This study aimed to investigate the serum profiling with magnetic bead (MB) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) and to further identify the biomarkers for HCC. Serum samples from 80 chronic(More)
Patients with esophageal squamous cell carcinoma (ESCC) are often diagnosed with advanced diseases that respond poorly to chemotherapy. Here we reported that Apollon, a membrane-associated inhibitor of apoptosis protein, was overexpressed in ESCC cell lines and clinical ESCC tissues, and Apollon overexpression clinically correlated with poor response to(More)
In this work, mixed-mode silica particles functionalized with octyl and sulfonic acid groups was conveniently prepared by co-bonding a mixture of n-octyltriethoxysilane and 3-mercaptopropyltriethoxysilane and then oxidized with hydrogen peroxide. Candida rugosa lipase (CRL) was immobilized on the mixed-mode silica particles via hydrophobic and strong(More)
The neural cell adhesion molecule CHL1 (close homolog of L1) plays important roles in neurite outgrowth and neuronal survival in vitro. Reproducible and functionally active CHL1 antibodies are critical for a better understanding of the functional properties of CHL1 in vitro and in vivo. We have isolated human single-chain variable fragment (scFv) antibodies(More)
Osteosarcoma (OS) is the most frequent primary bone sarcoma and tends to develop pulmonary metastasis. Studies have shown that mesenchymal stem cells (MSCs) are involved in OS growth and metastasis, but the mechanism remains unclear. The aim of the present study was to identify whether homologous MSCs could promote the growth and metastasis of OS in rats(More)
