Project description:Urethra was partially ligated and the urinary bladder was removed 10 days or 6 weeks after obstruction. Sham operated rats were used as controls. An addtitonal group of rats were repoerated 6 weeks after surgery and the obstruction was removed. These rats were then sacrificed 10 days after deobstruction. The bladder (including the urothelium) was frozen and used for RNA extraction. Urinary bladders from sham-operated, 10 days and 6 weeks after obstruction and rats 10 days after deobstruction were compared. mRNA and microRNA were both analyzed.

Project description:Bladder outlet obstruction (BOO) causes lower urinary tract symptoms and objectifiable urodynamic changes in bladder function. We carried out an integrated transcriptome and proteome analysis of bladder samples from male patients with BOO before and 3 months after de-obstruction surgery (transurethral resection of the prostate, TURP). mRNA and protein profiles were correlated with urodynamic findings, specifically voiding detrusor pressure (PdetQmax) before TURP. Patients with high PdetQmax showed less advanced remodeling and inflammatory changes than those with lower values. We oberved significant dysregulation of gene expression, which was reversed by de-obstruction in both patients’ groups. We propose a series of biomarker genes, indicative of BOO, and possibly contributing to the bladder changes. Our data sheds light on the stages of progressive obstruction-induced bladder decompensation, and might add selecting the operation point to avoid the loss of contractility.

Project description:Collagen 17A1 (COL17A1) is induced in urothelium under disease conditions of urinary system organs, such as chronic nephritis and urinary obstruction. Thus, the ureters of Col17a1-knock out (KO) mice were injured by unilateral ureteral obsruction (UUO), and the gene expression was compared with those of wild-tyoe (WT).

Project description:Early stages of ureteral obstruction are marked by polyuria with impaired urinary concentrating ability, associated with loss of aquaporin-2 (AQP2) expression. Most mechanistic work in unilateral ureteral obstruction (UUO) models has been done at relatively late time points, making it difficult to discriminate the early effect on collecting ducts (CDs) in gene expression. Here, we use single-tubule RNA-Seq to identity signaling pathways at earlier time points after UUO in rat models.
