To test the hypothesis that hypoxia plays a role in overactive bladder (OAB) symptoms by studying how the in vitro stretch of primary cultured bladder urothelial cells (BUCs) from those with OAB and asymptomatic subjects altered the expression of angiogenic factors. The angiogenic factors included hypoxia-inducible factor-1 alpha subunit (HIF-1α), HIF-2 alpha subunit (HIF-2α), and vascular endothelial...
To determine whether antiproliferative factor (APF) or epidermal growth factor (EGF) can induce changes in purinergic signaling in normal bladder urothelial cells (BUCs) and/or whether antagonizing EGF activity or blocking adenosine triphosphate (ATP)-purinergic receptors can induce changes in purinergic signaling in interstitial cystitis (IC) cells.IC and normal BUCs were obtained from patients'...
To explore muscarinic receptor signaling in 4 bladder cancer cell lines, bladder urothelial cells (BUC) have been shown to release and respond to various putative neurotransmitters.Reverse transcription-polymerase chain reaction was used to detect the presence of m1-m5 transcripts in the J82, RT4, T24, and 5637 lines of cancer BUC. Immunofluorescence was used to detect expression of m3 protein. Cancer...
To examine the association between three x-ray repair cross-complementing group 1 (XRCC1) genetic polymorphisms (Arg 194 Trp, Arg 280 His, and Arg 399 Gln) and bladder cancer susceptibility.A comprehensive search was conducted to identify all case-control studies of XRCC1 polymorphisms and bladder cancer risk. Statistical analysis was performed with the software program Review...
Objectives. Recent data suggest that the bladder urothelium may have a sensory function by way of release of adenosine triphosphate (ATP) during stretch, which then acts as a sensory neurotransmitter. Because benign prostatic hyperplasia (BPH) can give rise to irritative (hypersensory) voiding patterns, we questioned whether the bladder urothelium from patients with BPH released more ATP during in...
