Project description:Changes in human bladder epithelial cell gene expression associated with interstitial cystitis or antiproliferative factor treatment. Explanted bladder epithelial cells from patients with interstitial cystitis (IC) have been shown to differ from explanted control cells in several ways, including production of an antiproliferative factor (APF), altered production of certain epithelial growth factors, and rate of proliferation. To better understand the role of the APF in abnormal bladder epithelial cell proliferation in IC, we studied gene expression patterns in normal bladder epithelial cells treated with APF vs. mock APF and compared them to expression patterns in IC vs. normal cells using microarray analysis. Oligo-dT-primed total cellular RNA was labeled with [33P]dCTP and hybridized to GeneFilter GF211 microarray membranes (Research Genetics) containing cDNA for 3,964 human genes. Thirteen genes that function in epithelial cell proliferation or differentiation were consistently differentially expressed in both IC (compared with control) and APF-treated (compared with mock APF-treated) normal bladder epithelial cells. The general pattern of gene expression in IC and APF-treated cells suggested a less proliferative phenotype, with increased expression of E-cadherin, phosphoribosylpyrophosphate synthetase-associated protein 39, and SWI/SNF complex 170-kDa subunit, and decreased expression of vimentin, {alpha}2-integrin, {alpha}1-catenin, cyclin D1, and jun N-terminal kinase 1; these findings were confirmed for the structural gene products (E-cadherin, vimentin, {alpha}2-integrin, and {alpha}-catenin) by immunohistochemistry. These results are compatible with the previously noted decreased proliferation rate of IC and APF-treated normal cells, and indicate that the mechanism whereby APF inhibits cell proliferation may involve both downregulation of genes that stimulate cell proliferation along with upregulation of genes that inhibit cell growth.

Project description:Interstitial cystitis (IC), a chronic bladder disease with an increasing incidence, is diagnosed using subjective symptoms in combination with cystoscopic and histological evidence. The ultimate goal is the development of a diagnostic assay for IC on a molecular level. By cystoscopic examination, IC can be classified into an ulcerative and a non-ulcerative subtype. To better understand this debilitating disease on a molecular level, a comparative gene expression profile of bladder biopsies from patients with ulcerative IC and control patients has been performed. Candidate marker genes for ulcerative IC were identified.

Project description:Interstitial cystitis (IC) is a progressive chronic bladder disease with an increasing incidence. Today, IC is diagnosed by subjective symptoms in combination with cystoscopic and histologic evidence. The ultimate goal is the development of a diagnostic assay for IC on a molecular level. A comparative gene expression profile of bladder biopsies from patients with IC and control patients identified candidate marker genes for IC. Experiment Overall Design: Five IC patients and six control patients ('healthy') have been selected for the study. All IC patients had Hunner's ulcers and, with the exception of one person, also glomerulations, whereas the control group did not show these cystoscopic findings. From each IC patient two biopsies have been taken, one from an ulcerated area of the bladder ('ulcus'), and one from an area that macroscopically looked 'normal', 'not-inflamed' or not hyperemic ('ni'). One 'ni' sample has been excluded from the study because it had an expression pattern similar to the healthy controls.

Project description:Interstitial cystitis (IC) and bladder pain syndrome are terms used to describe a heterogenous chronic pelvic and bladder pain disorder of unknown etiology. The goal of this pilot study was to determine if gene expression profiling of bladder biopsy tissue from patients experiencing symptoms could be used to separate the patients based on some clinical parameter.

Project description:Interstitial cystitis (IC) and bladder pain syndrome are terms used to describe a heterogenous chronic pelvic and bladder pain disorder of unknown etiology. The goal of this pilot study was to determine if gene expression profiling of bladder biopsy tissue from patients experiencing symptoms could be used to separate the patients based on some clinical parameter. Gene expression profiles in bladder biopsy tissue from patients with: (1) low bladder capacity (defined here as <400 ml upon hydordistension), (2) normal capacity (M-bM-^IM-%400 ml), and (3) controls were compared. Gene expression profiles from low bladder capacity tissues differed significantly from normal capacity and control tissue, suggesting gene expression profiling may be a useful tool for better understanding IC disease pathophysiology.

Project description:Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a clinical condition that manifests as a sensory hypersensitivity of unknown cause and is characterized by urinary frequency, bladder discomfort, and pelvic pain. In the present volatolomic study, we have analyzed the VOCs unique to urine specimens obtained from interstitial cystitis patients, in compassion to healthy controls.This is the novel finding from comprehensive and unbiased metabolomics analysis that urinary menthol is decreased in urine specimens from IC patients, and that the reduced menthol level in IC is potentially linked to the chronic inflammation, which is often observed in IC patients

Project description:Purpose: Evaluate gene expression profiles after inducing differentiation in cultured interstitial cystitis (IC) and control urothelial cells. Materials and Methods: Bladder biopsies were taken from IC patients and controls (women having surgery for stress incontinence). Primary cultures were grown in Keratinocyte Growth Medium with supplements. To induce differentiation, in some plates the medium was changed to DMEM-F12 with supplements. RNA was analyzed with Affymetrix chips. Three nonulcer IC patients were compared with three controls. Results: After inducing differentiation, 302 genes with a described function were altered at least 3-fold with p <0.01 in both IC and control cells. Functions of the162 upregulated genes included cell adhesion (e.g. claudins, occludin, cingulin); urothelial differentiation, retinoic acid pathway and keratinocyte differentiation (e.g. skin cornified envelope components). The 140 downregulated genes included genes associated with basal urothelium (e.g. p63, integrins ?4, ?5 and ?6, basonuclin 1 and extracellular matrix components), vimentin, metallothioneins and members of the Wnt and Notch pathways. Comparing IC vs. control cells after differentiation, only seven genes with a described function were altered at least 3-fold with p <0.01. PI3, SERPINB4, CYP2C8, EFEMP2 and SEPP1 were decreased in IC; AKR1C2 and MKNK1 were increased in IC. Conclusions: Differentiation-associated changes occurred in both IC and control cells. Comparing IC vs. control revealed very few differences. This study may have included IC patients with minimal urothelial deficiency and/or selected the cells that were most robust in culture. Also, the abnormal urothelium in IC may be due to post-translational changes and/or the bladder environment. Experiment Overall Design: Human female urothelial cell cultures, differentiated vs. non-differentiated,interstitial cystitis vs. control
