Islet replacement therapy is limited by shortage of donor islet cells. Usage of islet cells derived from porcine pancreatic stem cells (PSCs) is currently viewed as the most promising alternative for human islet transplantation. However, PSCs are rare and have a finite proliferative lifespan. In this study, we isolated and established an immortalized(More)
OBJECTIVE To identify disease-related genes and immune-regulatory pathways in the pathogenesis of systemic lupus erythematosus (SLE) by using gene expression profiling and protein-protein interaction analysis. METHODS Peripheral white blood cell gene expression profiles of 10 SLE patients were determined by oligonucleotide microarray analysis. Clustering(More)
To understand the expression of NADPH oxidase components during neutrophil maturation, we examined the expression of mRNAs and proteins for NADPH oxidase components, and the superoxide-producing activity using HL-60 cells incubated with dimethyl sulfoxide (DMSO). Northern blot and Western blot analyses revealed that gp91(phox), p67(phox), and p47(phox) were(More)
OBJECTIVES Recent lines of evidence have indicated that miR-34c can play important roles in regulation of the cell cycle, cell senescence and apoptosis of mouse and human tumour cells, spermatogenesis, and male germ-cell apoptosis. However, there is little information on the effects of miR-34c on proliferation and apoptosis of livestock male germ cells. The(More)
OBJECTIVE Glucosamine, a naturally occurring amino monosaccharide has been used to treat or prevent osteoarthritis in humans. In this study, we evaluated the effect of glucosamine on rat adjuvant arthritis, a model of rheumatoid arthritis. MATERIALS AND METHODS Adjuvant arthritis was induced in male Wistar rats by injection of Freund's complete adjuvant(More)
Glucosamine, an amino monosaccharide naturally occurring in the connective and cartilage tissues, contributes to maintaining the strength, flexibility, and elasticity of these tissues. In recent years, glucosamine has been used widely to treat osteoarthritis in humans and animal models. Neutrophils, which usually function as the primary defenders in(More)
I/R injury is the main cause for hepatic dysfunction and failure after liver transplantation and liver resection. Therefore, reduction of I/R injury is the most important goal to improve the outcome of these procedures. Olprinone is a newly developed selective phosphodiesterase III inhibitor, which has been reported to ameliorate renal I/R injury in rats.(More)
OBJECTIVE Superoxide-generating NADPH oxidase consists of the membrane-bound cytochrome b558 (gp91phox and p22Phox) and the cytosolic components (p67phox, p47phox, p40phox and rac). In this study, we evaluated the superoxide-generating activity and the expression of NADPH oxidase components during eosinophilic maturation using HL-60 clone 15 cell line. (More)
HIV-host infection systems in vitro are important in the pre-clinical assessment of anti-retroviral drug activity. The present report describes the development of a new HIV-host model comprised of an epithelial cell line of HeLa lineage (HeLa-1), transfected with expression vectors bearing tat and rev (TART) genes of HIV-1 as well as the CD4 receptor gene,(More)
Our previous studies indicated that an alternatively spliced variant mRNA of p40-phox, a cytosolic component of NADPH oxidase, is expressed but its protein is hardly detected in myeloid cells such as promyelocytic HL-60 cells and neutrophils. Here, we have examined the stability of p40-phox variant protein in undifferentiated HL-60 cells. When in(More)
