Expression and function of transforming growth factor-beta isoforms and cognate receptors in rat urinary bladder following cyclophosphamide-induced cystitis.

Expression and function of transforming growth factor-beta isoforms and cognate receptors in rat urinary bladder following cyclophosphamide-induced cystitis. Am J Physiol Renal Physiol. 2013 Aug 7; Authors: Gonzalez EJ, Girard BM, Vizzard MA Abstract Numerous proinflammatory cytokines have been implicated in the reorganization of lower urinary tract function following cyclophosphamide (CYP)-induced cystitis. The present study investigated the functional profile of three pleiotropic transforming growth factor-beta (TGF-β) isoforms and receptor (TβR) variants in the normal and inflamed (CYP-induced cystitis) rat urinary bladder. Our findings indicate that TGF-β (1, 2 and 3) and TβR (1, 2 and 3) transcript and protein expression were regulated to varying degrees in the urothelium or detrusor smooth muscle following intermediate (48 h; 150 mg/kg, i.p.) or chronic (75 mg/kg, i.p.; once every three days for ten days), but not acute (4 h; 150 mg/kg, i.p.), CYP-induced cystitis. Conscious, open outlet cystometry was performed to determine whether aberrant TGF-β signaling contributes to urinary bladder dysfunction following intermediate (48 h) CYP-induced cystitis. TβR-1 inhibition with SB505124 (5 µM) significantly (p ≤ 0.001) decreased voiding frequency and increased bladder capacity (2.5-fold), void volume (2.6-fold) and intercontraction intervals (2.5-fold) in CYP-treated (48 h) rats. Taken together, these results provide evi...

AbstractNeural injury, inflammation, or diseases commonly and adversely affect micturition reflex function that is organized by neural circuits in the CNS and PNS. One neuropeptide receptor system, pituitary adenylate cyclase-activating polypeptide (PACAP;Adcyap1), and its cognate receptor, PAC1 (Adcyap1r1), have tissue-specific distributions in the lower urinary tract. PACAP and associated receptors are expressed in the LUT and exhibit changes in expression, distribution, and function in preclinical animal models of bladder pain syndrome (BPS)/interstitial cystitis (IC), a chronic, visceral pain syndrome characterized by ...

Abstract Diabetes mellitus (DM) is a common disease in Oman as in rest of Gulf Cooperation Council where metabolic syndrome is of high prevalence. DM is a foremost risk factor for urinary tract infections (UTIs). It is also linked to more complicated infections such as emphysematous pyelonephritis (EPN), emphysematous pyelitis (EP), renal/perirenal abscess, emphysematous cystitis, xanthogranulomatous pyelonephritis, and renal papillary necrosis. The diagnosis of these cases is frequently delayed because the clinical manifestations are generic and not different from the typical triad of upper UTI, which include fev...

ConclusionsThe present study showed that CYP-induced cystitis in mice is a model of visceral hyperalgesia affecting detrusor contractions, not urethral activations. The technique of using EUS  EMG to evaluate the drug effects on urethral activities is novel and useful for future investigations. Gabapentin can be as a potential treatment for detrusor overactivity and PBS/IC.

CONCLUSION: It seems that menthol and its receptors are involved in vesico-sphincteral physiopathology and could provide therapeutic potential in detrusorian overactivity and interstitial cystitis with reduced toxicity. PMID: 30098904 [PubMed - as supplied by publisher]

AbstractPituitary adenylate cyclase-activating polypeptide (PACAP;Adcyap1) and its cognate PAC1 receptor (Adcyap1r1) have tissue-specific distributions in the lower urinary tract (LUT). The afferent limb of the micturition reflex is often compromised following bladder injury, disease, and inflammatory conditions. We have previously demonstrated that PACAP signaling contributes to increased voiding frequency and decreased bladder capacity with cystitis. Thus, the present studies investigated the sensory components (e.g., urothelial cells, bladder afferent nerves) of the urinary bladder that may underlie the pathophysiology ...

Abstract Chronic pelvic pain causes significant patient morbidity and is a bane to clinicians. Using a murine neurogenic cystitis model that recapitulates key aspects of interstitial cystitis/bladder pain syndrome (IC), we recently showed that pseudorabies virus (PRV) induces severe pelvic allodynia in BALB/c mice, relative to C57BL/6 mice. Here, we report that a quantitative trait locus (QTL) analysis of PRV-induced allodynia in F2CxB progeny identified a polymorphism on chromosome 13, rs6314295, significantly associated with allodynia (LOD=3.11). The nearby gene encoding acyloxyacyl hydrolase, (Aoah), was induce...

Abstract Dyskeratosis congenita is a rare congenital telomeropathy characterized by cutaneous and nail dystrophy, oral leukoplakia, and bone marrow failure. Pulmonary fibrosis and cancers are late manifestations. Allogeneic hematopoietic stem cell transplant represents the only cure for those with bone marrow failure with this disease, but outcomes reported are overall poor, with organ toxicities, graft failure, and graft-versus-host disease as main issues. Although reduced intensity conditioning regimens seem to be related to better outcomes, a standard regimen for dyskeratosis congenita has never been defined. H...
