Project description:Chronic pelvic pain syndrome (CPPS) and chronic prostatitis (CP) is difficult to distinguish from each other, herein termed CP/CPPS. This study aimed at gaining further insight into the change of extracellular vesicles (EVs) in prostatic fluid of male CPPS. From December 2019 to November 2020, after clinical screening, 24 patients with CPPS without obvious urinary symptoms and 13 healthy male participants were included. EVs were isolated from expressed prostatic secretion (EPS) of all subjects. The small non-coding ribonucleic acid (sncRNA) expression of EVs was sequenced, analysed, and validated by quantitative real-time polymerase chain reaction (qRT-PCR) assays. The results showed that plenty of sncRNAs were differentially expressed between the patients and healthy participants. Further qRT–PCR assays validated that several chronic pain-related miRNAs, including miR-204-5p, let-7d-3p, let-7b-3p, let-7c-3p, miR-146a-5p, and miR-320a-5p, were differentially expressed. Series sncRNAs including several chronic pain-related miRNAs were altered in EVs in prostatic fluid of patients with CPPS, which may serve as diagnostic markers for CPPS.

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:There is an imminent need for safe and efficient chronic pain medications. Regulator of G-protein signaling 4 (RGS4) is a multi-functional signal transduction protein, widely expressed in the pain matrix. Here, we demonstrate that RGS4 plays a prominentrole in the maintenance of chronic pain symptoms in male and female mice. Using genetically modified mice, we show a dynamicrole of RGS4 in recovery from symptoms of sensory hypersensitivity deriving from hindpaw inflammation or hindlimb nerveinjury. We also demonstrate an important role of RGS4 actions in gene expression patterns induced by chronic pain states in themouse thalamus. Our findings provide novel insight into mechanisms associated with the maintenance of chronic pain states anddemonstrate that interventions in RGS4 activity promote recovery from sensory hypersensitivity symptoms.

Project description:Urinary chronic pelvic pain syndrome (UCPPS) is a condition of unknown etiology characterized by pelvic pain, and urinary frequency and/or urgency. As the proximal fluid of this disease, urine is an ideal candidate sample matrix for an unbiased study of UCPPS. In this study, a large, discovery-phase, TMT-based quantitative urinary proteomics analysis of 244 subjects was performed. The subjects included patients with UCPPS (n=82), healthy controls (HC) (n=94) and other chronic pain diseases, termed positive controls (PC) (n=68). Utilizing training and testing cohorts , we identified and validated a small and distinct set of proteins that distinguished UCPPS from HC (n=7) and UCPPS from PC (n=3). Validated UCPPS:HC proteins were predominantly ECM/ECM modifying or immunomodulatory/host defense in nature. Significantly,varying proteins in the UCPPS:HC comparison were overrepresented by members of several dysregulated biological processes including decreased immune cell migration, decreased development of epithelial tissue and increased bleeding. Comparison with the PC cohort enabled evaluation of UCPPS-specific upstream regulators, contrasting UCPPS with other conditions that cause chronic pain. Specific to UCPPS were alterations in the predicted signaling of several upstream regulators, including alpha-catenin, IL6, EGF and TGFB1, among others. These findings advance our knowledge of the etiology of UCPPS and inform potential future clinical translation into a diagnostic panel for UCPPS.

Project description:Chronic pain remains a significant medical challenge with complex underlying mechanisms, and an urgent need for new treatments. Our research built and utilized the iPain single-cell atlas to study chronic pain progression in dorsal root and trigeminal ganglia. We discovered that senescence of a small subset of pain-sensing neurons may be a key driver of chronic pain. This mechanism was observed in animal models after nerve injury and in human patients with chronic pain or diabetic neuropathy. Notably, treatment with senolytics, drugs that remove senescent cells, reversed pain symptoms in mice post-injury. These findings highlight the crucial role of cellular senescence in chronic pain development, demonstrate the therapeutic potential of senolytic treatments, and underscore the value of the iPain atlas for future pain research.

Project description:Endometriosis is a common disease seen by gynecologists. Clinical features involve pelvic pain and unexplained infertility. Although endometriosis is pathologically characterized by endometrial tissue outside the normal uterine location, endometriosis is otherwise not easily explained. Endometriomas, endometriotic cysts of the ovary, typically cause pain and distortion of pelvic anatomy. To begin to understand the pathogenesis of endometriomas, we carried out transcriptome:microRNAome analysis of endometriomas and eutopic endometrium, using gene expression arrays and next generation small RNA sequencing technology. Keywords: two group comparison Patients undergoing surgery for endometriomas, suspected endometriosis, pelvic pain, abnormal uterine bleeding, pelvic organ prolapse, or uterine leiomyomas were approached for participation. After informed consent, the patients underwent scheduled surgical procedure. Tissues were collected either as cyst wall of endometrioma or endometrial curettage of hysterectomy specimen and placed directly into RNALater (Ambion, Austin, TX) and eventually frozen at -80?C. Samples were designated as endometriomas or non-endometriosis control endometrium based on surgical pathology reports. Total RNA was isolated from frozen tissue. High quality RNA was subjected to Illumina’s Human WG-6 version 2.0 BeadChips (Illumina). . *** This Series represents the transcriptome component of the study. ***
