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/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)/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: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:Hunner-type interstitial cystitis (HIC) is a rare, enigmatic inflammatory disease of the urinary bladder with no curative treatments. In this study, we aimed to characterize the unique cellular and immunological factors specifically involved in HIC by comparing with cystitis induced by Mycobacterium bovis bacillus Calmette–Guérin, which presents similar clinicopathological features to HIC. Here, we show that T helper 1/17 polarized immune responses accompanied by prominent overexpression of interferon (IFN)-γ, enhanced cGAS-STING cytosolic DNA sensing pathway, and increased plasma cell infiltration are the characteristic inflammatory features in HIC bladder. Further, we developed a novel mouse anti-IFN-γ DNA aptamer and observed that intravesical instillation of the aptamer significantly ameliorated bladder inflammation, pelvic pain and voiding dysfunction in a recently developed novel murine HIC mouse model with little migration into the blood. Our study provides the plausible basis for clinical translation of the anti-IFN-γ DNA aptamer in the treatment of human HIC.
