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:The aim of this cDNA array study is to search for advanced markers related to the pathogenesis of ketamine-induced cystitis. The result revealed a number of gene expressions involved in chronic wound healing response and collagen accumulation, which were closely related to fibrosis progression in the connective tissue of mice urinary bladder.

Project description:Molecular mechanism underlying regeneration process, triggered by stem cells in tissue engineered urinary bladder, is still poorly explained. The study aimed to explore underlining pathways associated with regeneration process in urinary bladder reconstructed with stem cell seeded graft. The study was performed on 110 Wistar rats. Urinary bladders were augmented with bladder acellular matrix (BAM)(n=52) or BAM seeded with adipose derived stem cells (ADSCs)(n=52). The process of bladder healing was analyzed at 7, 30, 90 and 180 days postoperatively. Gene expression was evaluated using microarrays and analyzed in GeneSpring Software. Gene ontology (GO) and pathway enrichment analyses of differentially expressed genes (DEGs) were performed. A total of 4023, 4674, 7997 and 1120 of DEGs between the bladders augmented with ADSCs seeded BAM and BAM only were identified at 7, 30, 90 and 180 days postoperatively, respectively. The DEGs were enriched in GO terms associated with cellular and intercellular events, morphogenesis, epithelium, smooth muscles and nerves regeneration, angiogenesis, inflammatory response and wound healing. Numerous differentially expressed pathways between the bladders augmented with ADSCs seeded BAM and BAM only were identified. In conclusion, this study provided the unequivocal evidence that stem cells changed healing milieu in tissue engineered urinary bladder and indicated underlying pathways that can be associated with regeneration process triggered by stem cells.

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:Impaired skin wound healing is a significant global health issue, especially among the elderly. Wound healing is a well-orchestrated process involving the sequential phases of inflammation, proliferation, and tissue remodeling. Although wound healing is a highly dynamic and energy-requiring process, the role of metabolism remains largely unexplored. By combining transcriptomics and metabolomics of human skin biopsy samples, we mapped the core bioenergetic and metabolic changes in normal acute as well as chronic wounds in elderly subjects. We found upregulation of glycolysis, the tricarboxylic acid cycle, glutaminolysis, and β-oxidation in the later stages of acute wound healing and in chronic wounds. To ascertain the role of these metabolic pathways on wound healing, we targeted each pathway in a wound healing assay as well as in a human skin explant model using metabolic inhibitors and stimulants. Enhancement or inhibition of glycolysis and, to a lesser extent, glutaminolysis had a far greater impact on wound healing than similar manipulations of oxidative phosphorylation and fatty acid β-oxidation. These findings increase the understanding of wound metabolism and identify glycolysis and glutaminolysis as potential targets for therapeutic intervention.

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.
