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:Examination of E. coli transcripts present in bacteria in urine samples from 8 patients attending a urology clinic with symptoms of cystitis, as compared to transcripts present in the same E. coli strains during mid-exponential growth in filter-sterilized human urine in vitro.
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:Examination of E. coli transcripts present in bacteria in urine samples from 8 patients attending a urology clinic with symptoms of cystitis, as compared to transcripts present in the same E. coli strains during mid-exponential growth in filter-sterilized human urine in vitro. A 48 array study using total RNA recovered from eight clinical E. coli isolates immediately following collection from women and following culture in pooled human urine ex vivo. Each array measures the expression of the 5,379 ORFs in the CFT073 genome, using an average of 14 60-mer probes per ORF. Arrays were performed in triplicate: biological replicates of the in vitro-cultured samples and technical replicates of the in vivo samples.
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:We report the application of single cell RNA-seq for transcript profiling in bladder tissue from Interstitial cystitis/bladder pain syndrome (IC/BPS) with Hunner lesions and without Hunner lesions and normal tissue.
