We examined whether survivin acts as a constitutive and inducible radioresistance factor in pancreatic cancer cells. Using a quantitative TaqMan reverse transcription-polymerase chain reaction for survivin mRNA in five pancreatic cancer cell lines, we found an inverse relationship between survivin mRNA expression and radiosensitivity. PANC-1 cells, which(More)
We investigated the significance of endogenous reactive oxygen species (ROS) produced by fungi treated with miconazole. ROS production in Candida albicans was measured by a real-time fluorogenic assay. The level of ROS production was increased by miconazole at the MIC (0.125 micro g/ml) and was enhanced further in a dose-dependent manner, with a fourfold(More)
We established the validity of a quantitative reverse transcription (RT)-PCR assay for the RNA component of human telomerase (hTR), using the TaqMan fluorogenic detection system. Using this assay, we quantified hTR expression in two human pancreatic cancer cell lines, ASPC-1 and MIAPaCa-2. Our results indicated that hTR expression in MIAPaCa-2 was 1.99-fold(More)
MecA, a structural gene located on the chromosome of Staphylococcus aureus, characterizes methicillin-resistant S. aureus (MRSA), and femA and femB(fem) genes encode proteins which influence the level of methicillin resistance of S. aureus. In order to examine effectiveness of detecting mecA and fem genes in identification of MRSA, the presence of these(More)
BACKGROUND The significance of serum concentrations of tumor necrosis factor-alpha (TNF-alpha) in the pathogenesis of inflammatory bowel disease (IBD) is uncertain. We measured TNF-alpha in serum from IBD patients by immuno-PCR to analyze the relationship between TNF-alpha and pathophysiologic state in IBD. METHODS Serum samples were collected from 54(More)
A molecular typing method for Staphylococcus aureus based on coagulase gene polymorphisms (coagulase gene typing) was evaluated by examining a total of 240 isolates which comprised 210 methicillin-resistant S. aureus (MRSA) and 30 methicillin-susceptible S. aureus (MSSA) collected from a single hospital. By AluI restriction enzyme digestion of the(More)
Abdominal multivisceral allotransplantation (MVTX) from Brown Norway donor rats to Lewis recipient rats was performed under a 14-day course of low (0.32 mg/kg) or high-dose (0.64 mg/kg) intramuscular FK 506 to which weekly further injections were added in some of the high-dose animals. With all three regimens, long survival was frequently achieved with good(More)
The molecular nature of a tumor-specific transplantation antigen (TSTA) of a chemically induced BALB/c mouse colon tumor C-C26 was investigated. The antigen was noncytolytically extracted by 2.5% n-butanol treatment of the cells. Crude butanol extract from C-C26, but not from colon tumor C-C51 and fibrosarcoma Meth-A of BALB/c mice could provide protection(More)
