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/bladder pain syndrome (IC/BPS) is a chronic and debilitating pain disorder of the bladder and urinary tract with poorly understood etiology. A definitive diagnosis of IC/BPS can be challenging because many symptoms of IC/BPS are shared with other urological disorders. An analysis of urine presents an attractive and non-invasive resource for monitoring and diagnosing IC/BPS. Here, a non-targeted LC-MS and LC-MS/MS-based peptidomics analysis of urine samples collected from IC/BPS patients were compared to urine samples from asymptomatic controls.

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. 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:Recent evidence suggests that the descending modulatory pathways from the brainstem rostral ventromedial medulla (RVM) are important for bladder inflammatory pain. This study aimed to identify the long-term molecular changes in RVM neurons due to early life cystitis during neuronal development and the effect of reexposure later in adulthood. RVM tissues from two treatment protocols were used: (1) neonatal zymosan exposures with acute adult rechallenge (RC) and (2) only neonatal zymosan exposures (NRC). RNAseq analysis showed upregulation of several genes associated with synaptic plasticity (Grin1, Grip2, Notch1, Arc, and Scn2b) in the cystitis groups compared to controls in both protocols. The RC protocol exhibited a stronger treatment effect with significantly higher fold differences between the groups compared to the NRC protocol (p<0.001, fold differences RC vs NRC). In microarrays, miR-34a-5p showed cystitis-induced downregulation in both protocols. Bioinformatics analysis identified multiple 3’UTRs complementary binding sites for miR-34a-5p on Grin2b, Notch1, Grip2, Scn2b, and Arc genes. The enhanced response in the RC protocol indicates a possible priming effect of early life cystitis on rechallenge in adulthood. These long-term molecular alterations may play a critical role in the development of chronic bladder pain conditions as seen in patients with Interstitial Cystitis/Bladder pain syndrome

Project description:The pathogenesis of interstitial cystitis/bladder pain syndrome (IC/BPS) remains incompletely understood. Bladder fibrosis is a significant histopathological feature of IC/BPS, particularly in non-Hunner-type IC (NHIC). Transient receptor potential cation channel subfamily C member 3 (TRPC3) is known to play a crucial role in myocardial and renal fibrosis. This study investigates the involvement of TRPC3 in bladder fibrosis associated with IC/BPS. A rat model of IC/BPS was established using cyclophosphamide (CYP, 50 mg/kg, intraperitoneally, every 3 days for 3 doses). Bulk RNA sequencing was used to identify differentially expressed transient receptor potential (TRP) channel genes in CYP-induced cystitis rats, whereas single-cell RNA sequencing was utilized to pinpoint the cell type predominantly expressing transient receptor potential cation channel subfamily C member 3 (TRPC3) . TRPC3 inhibition was achieved through intraperitoneal injection of Pyrazole 3 (Pyr3, 0.1 mg/kg or 1 mg/kg). Suprapubic mechanical allodynia was assessed using up-down method with von Frey filaments and micturition frequency was assessed by cystometry. The expression of TRPC3 and components of the transforming growth factor beta (TGF-β)/Smad signaling pathway (TGF-β, p-Smad2, and p-Smad3) in the bladder was analyzed by Western blot. Bladder fibrosis was assessed through Masson’s staining and detection of fibrosis markers (Vimentin, Collagen I, and Collagen III) using Western blot. The RNA and protein expression of TRPC3 was up-regulated in CYP-induced cystitis rats. TRPC3 inhibition led to significant improvements in suprapubic mechanical allodynia and reduced micturition frequency in CYP-induced cystitis rats. Western blot analyses revealed that markers of bladder fibrosis (Vimentin, Collagen I, and Collagen III) were markedly upregulated in CYP-induced cystitis rats. Masson’s staining showed an increased area of collagen fibers. Additionally, inhibition of TRPC3 resulted in significant downregulation of the TGF-β/Smad signaling pathway (TGF-β, p-Smad2, and p-Smad3) in CYP-induced cystitis rats. TRPC3 activation contributes to bladder fibrosis in IC/BPS. Inhibition of TRPC3 ameliorates suprapubic mechanical allodynia and micturition frequency in CYP-induced cystitis rats by downregulating the TGF-β/Smad pathway. TRPC3 represents a potential therapeutic target for managing bladder fibrosis in IC/BPS.

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

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.
