NPR1 (a non-expressor of pathogenesis-related genes1) has been reported to play an important role in plant defense by regulating signaling pathways. However, little to nothing is known about its function in herbivore-induced defense in monocot plants. Here, using suppressive substrate hybridization, we identified a NPR1 gene from rice, OsNPR1, and found(More)
OBJECTIVE To investigate whether immunological mechanisms may be involved in human luteal function. DESIGN The effects of the cytokines, interferon-alpha (IFN-alpha), interferon-gamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) on steroidogenesis by human luteal cells were examined in vitro. The dispersed human luteal cells, obtained from a(More)
Porcine mucosal heparin was partially depolymerized with heparin lyase I and then fractionated into low-molecular-weight (< 5000) and high-molecular-weight (> 5000) oligosaccharides by pressure filtration. The high-molecular-weight oligosaccharide mixture (approximately 50 wt% of the starting heparin) also contained intact heparin. This intact polymer(More)
Jasmonic acid (JA) and related metabolites play a key role in plant defense and growth. JA carboxyl methyltransferase (JMT) may be involved in plant defense and development by methylating JA to methyl jasmonate (MeJA) and thus influencing the concentrations of JA and related metabolites. However, no JMT gene has been well characterized in monocotyledon(More)
The versatile biological activities of proteoglycans are mainly mediated by their glycosaminoglycan (GAG) components. Unlike proteins and nucleic acids, no satisfactory method for sequencing GAGs has been developed. This paper describes a strategy to sequence the GAG chains of heparin. Heparin, prepared from animal tissue, and processed by proteinases and(More)
BACKGROUND Peripheral blood lymphocytes exhibit changes that parallel those in failing cardiomyocytes. We hypothesised that mitochondrial transmembrane potential (MTP) and reactive oxygen species (ROS) levels of lymphocytes are associated with serum NT-proBNP and short-term prognosis in patients with chronic heart failure (CHF). METHODS Fifty-four CHF(More)
qRT-PCR is becoming a routine tool in molecular biology to study gene expression. It is necessary to find stable reference genes when performing qRT-PCR. The expression of genes cloned in oil-tea camellia currently cannot be accurately analyzed due to a lack of suitable reference genes. We collected different tissues (including roots, stems, leaves, flowers(More)
The tumor microenvironment has been suggested to participate in tumorigenesis, but the nature of the communication between cancer cells and the microenvironment, especially in response to anticancer drugs, remains obscure. We determined that activation of the CCAAT/enhancer binding protein delta (CEBPD) response to Cisplatin and 5-Fluorouracil in(More)
Lectin affinity electrophoresis is a powerful technique to investigate the interaction between a lectin and its ligand. Affinity electrophoresis results from the reduced mobility of a charged species owing to its interaction with an immobile species. In this protocol, a two-dimensional lectin affinity electrophoresis experiment is described that affords(More)
The production of inhibin in vitro by dispersed cells from early to mid (Days 16-19) and late stage (Day 23) human corpus luteum (CL) was examined, and the effects of human chorionic gonadotrophin (hCG), follicle stimulating hormone (FSH), oestradiol and testosterone on inhibin production were determined. Corpora lutea from five subjects in the early to mid(More)
