S.c. painful inflammation leads to an increase in axonal transport of opioid receptors from dorsal root ganglia (DRG) toward the periphery, thus causing a higher receptor density and enhanced opioid analgesia at the injured site. To examine whether this increase is related to transcription, the mRNA of Delta- (DOR) and mu-opioid receptor (MOR) in lumbar DRG(More)
Promoter hypermethylation of the glutathione S-transferase P1 gene (GSTP1) is the most frequent DNA alteration in prostatic carcinoma. Because this epigenetic DNA alteration can be reliably detected by methylation-specific PCR (MSP), we applied this new technique for molecular detection of prostate cancer in various human bodily fluids. We investigated(More)
BACKGROUND Methylation-specific polymerase chain reaction (MSP) targeting promoter hypermethylation of the glutathione S transferase P1 gene (GSTP1), as the most frequent DNA alteration in prostatic carcinoma, was used for the molecular detection of cell-bound and cell-free prostate tumor DNA in various human bodily fluids. MATERIALS AND METHODS We(More)
Suppression of apoptosis may favor the onset and progression of cancer. Survivin is an inhibitor of apoptosis that has been suggested as a novel diagnostic/prognostic marker of bladder cancer. In this study, survivin mRNA expression was measured by a sensitive real-time PCR assay in tumor tissue and urine from bladder cancer patients and assessed for its(More)
BACKGROUND A novel gammaretrovirus named xenotropic murine leukemia virus-related virus (XMRV) has been recently identified and found to have a prevalence of 40% in prostate tumor samples from American patients carrying a homozygous R462Q mutation in the RNaseL gene. This mutation impairs the function of the innate antiviral type I interferon pathway and is(More)
To examine the significance of the methylation level of the p53 target and tumour suppressor genes apoptotic protease activating factor-1 (APAF-1) and death-associated protein kinase-1 (DAPK-1) in 80 microdissected tumour samples from transitional cell carcinoma (TCC) of the bladder and 80 tumour samples from clear-cell renal cell carcinoma (RCC) as well as(More)
OBJECTIVES Promoter hypermethylation of the glutathione-S-transferase P1 (GSTP1) gene is a specific feature of prostate cancer. This epigenetic DNA alteration served as the target for molecular detection of prostate cancer cells in urine sediments after prostatic massage. METHODS Bisulfite treatment followed by methylation-specific polymerase chain(More)
Deletions of DNA sequences on chromosome 3p [loss of heterozygosity (LOH)] are characteristic of clear cell renal carcinoma, which accounts for about 80% of all renal malignancies. Comparing tumor DNA to DNA from normal cells, LOH analysis of microsatellite sequences has aided in molecular diagnosis of renal carcinoma. Because clinically useful tumor(More)
PURPOSE Risk stratification of renal cell carcinoma is based on the histopathologic classification. Promoter hypermethylation as a mechanism of gene inactivation in renal cell carcinoma has been shown for only a small number of genes. We examined the usefulness of quantitative methylation analysis with a new set of p53 target genes for determining the(More)
Hyperpolarizing large-conductance, Ca(2+)-activated K(+) channels (BK) are important modulators of vascular smooth muscle and endothelial cell function. In vascular smooth muscle cells, BK are composed of pore-forming alpha subunits and modulatory beta subunits. However, expression, composition, and function of BK subunits in endothelium have not been(More)
