Project description:Bilateral freezing of the pelvic ganglia in female rats were performed to denervate the urinary bladder. Sham operated rats were used as controls. The rats were sacrificed 10 days after surgery. The urinary bladders (including the urothelium) were frozen and used for RNA extraction.

Project description:Analysis of urinary bladder in wild-type C57BL/6 females sacrificed every 4 hours at six time points under constant darkness after acclimation for 2 weeks under 12-hour light and 12-hour dark conditions. Results provide insight into circadian gene expression patterns in normal urinary bladder. Analysis of urinary bladder in wild-type C57BL/6 females sacrificed every 4 hours at six time points (n=2 for each time (CT 0, 4, 8, 12 and 20)) under constant darkness after acclimation for 2 weeks under 12-hour light and 12-hour dark conditions.

Project description:Diabetes mellitus (DM) is a leading cause of chronic kidney disease and the pathobiology of diabetic nephropathy is widely studied. Less, however, is known about urinary bladder disease in DM despite dysfunctional voiding being a common clinical problem. We hypothesised that diabetic cystopathy would have a characteristic molecular signature, due to the adaptive response to increased urine load combined with the metabolic impacts of DM. To distinguish the consequences of DM from polyuria we compared bladders of untreated control, diabetic (streptozotocin-induced) and sucrose-treated male Wistar rats after 16 weeks using gene array
Project description:Urinary bladder wound healing is today pooorly chracterized. MicroRNAs are small non-coding RNA molecules with regulatory functions. In this study we aimed at identifying microRNAs expressed during bladder wound healing. We performed Affymetrix microRNA profiling of the rodent urinary bladder during healing of a surgically created wound.
Project description:At diagnosis approximately 75% of bladder urothelial carcinomas are non muscle invasive bladder cancers (Ta, T1 and Tis), 20% are muscle invasive bladder cancer (T2-T4) and 5% are already metastatic. Non muscle invasive bladder cancers are characterized by tumor recurrence in 60% to 85% of cases and, therefore, long-term followup is needed. The current standard methods to detect and monitor bladder cancer are cystoscopy and cytology. Cystoscopy is an invasive method and cytology is hampered by low sensitivity, especially for low grade tumors. So there is need to develop reliable and noninvasive methods to detect and predict bladder cancer biological behavior. So we have performed high density oligonucleotide microarray for discovery of new molecular markers to diagnose and predict the outcome of bladder cancer. Under an ethical guideline of Chhatrapati Shahuji Maharaj Medical University, India histologically confirmed seven bladder cancer patients were recruited from Department of Urology, Chhatrapati Shahuji Maharaj Medical University, Lucknow, India. Total RNA was extracted from tumor biopsies and hybridized on affymetrix Human Gene ST 1.1 array to determine differentially expressed genes in urinary bladder cancer with muscle invasion in comparison of normal human urinary bladder.
