Membrane proteins are generally classified into the following five types: 1), type I membrane protein; 2), type II membrane protein; 3), multipass transmembrane proteins; 4), lipid chain-anchored membrane proteins; and 5), GPI-anchored membrane proteins. In this article, based on the concept of using the functional domain composition to define a protein,(More)
BACKGROUND We apply a new machine learning method, the so-called Support Vector Machine method, to predict the protein structural class. Support Vector Machine method is performed based on the database derived from SCOP, in which protein domains are classified based on known structures and the evolutionary relationships and the principles that govern their(More)
The core of an enzyme molecule is its active site from the viewpoints of both academic research and industrial application. To reveal the structural and functional mechanism of an enzyme, one needs to know its active site; to conduct structure-based drug design by regulating the function of an enzyme, one needs to know the active site and its(More)
Orosomucoid 1-like 3 (ORMDL3) gene was strongly linked with the development of asthma in genetic association studies, and its expression could be significantly induced by allergen in airway epithelial cells of mice. However, the expression mechanism of ORMDL3 was still unclear. Here we have identified and characterized the mouse ORMDL3 gene promoter.(More)
BACKGROUND Mast cells play a central role in allergic and inflammatory disorders by inducing degranulation and inflammatory mediator release. Recent reports have shown that miRNAs play an important role in inflammatory response regulation. Therefore, the role of miR-223 in mast cells was investigated. METHODS The expression of miR-223 was quantified by(More)
The CD2 associated protein (CD2AP) is characterized as a T-lymphocyte CD2 adapter protein and is found to be related to glomerulosclerosis, and CD2AP knockout mice develop a rapid onset nephrotic syndrome and die of renal failure. Here we report that the transcription factor Sp1 and Sp3 up-regulate the basal transcriptional activity of CD2AP and increase(More)
Neural cells undergo glutamate-induced apoptosis in ischaemic brain tissue, in which prostate apoptosis response-4 gene (Par-4) is involved. Human-bone mesenchymal stem cells can be utilized as an effective therapy for ischemic brain injury. In this study, we found that glutamate could induce apoptosis in human-bone mesenchymal stem cells, accompanied by(More)
Four new triterpenoids which were identifed as 2α,3β,6β,19α-tetrahydroxy- oleanolic acid 28-O-β-D-glucopyranoside (1), 2-O-β-D-glucopyranosyloxy-3α,19α-di-hydroxyoleanolic acid (2), 2-O-β-D-glucopyranosyloxy-3α,19α-dihydroxyursolic acid (3), 2α,3α,6β,19α-tetrahydroxyursolic acid 28-O-β-D-glucopyranoside (4), were isolated from the aerial parts of Callicarpa(More)
All-trans retinoic acid (ATRA) is an active metabolite of Vitamin A, it shows protective effects on asthma, including maintains airway epithelial integrity, inhibits asthma effector cells differentiation, modulates immune response, et al. However, the promoting effect of ATRA on Th2 response has restricted the clinical application of ATRA in asthma(More)
CD2-associated protein (CD2AP) is an adaptor molecule involved in T cell receptor signaling and podocyte homeostasis. CD2AP-deficient mice develop nephritic syndrome and renal failure caused by glomerulosclerosis. Transcription factor E2F1 is a key regulator of cell proliferation and apoptosis. Here we report that E2F1 up-regulates the human CD2AP promoter(More)
