Project description:The aim of the experiment was to determine the effect of cyclic stretch-relaxation ("stretch") on gene expression patterns in normal diploid human bladder smooth muscle cells. Cells plated on silicone elastomer bottomed 6-well culture dishes were grown to ~80% confluence, serum-depleted for 48h and subjected to cyclic stretch-relaxation at 20% elongation for 4h. Cells seeded in stretch plates but not subjected to stretch served as controls. Total RNA was extracted from both groups of cells, reverse-transcribed, biotin-labeled, fragmented and hybridized to HG-U133A. Four biological replicates were generated for each treatment group (non-stretched or stretched). Keywords = bladder Keywords = smooth muscle cells Keywords = cyclic stretch-relaxation Keywords: other

Project description:To explore global molecular changes in smooth muscle in response to PDGFR activation, primary human bladder smooth muscle cells were treated with 1 nM PDGF-BB (hereafter PDGF) for 0, 4 or 24 h. Total RNA were prepared, and analyzed using expression profiling, and subjected to bioinformatic and functional interrogation. To identify molecular signatures of bladder smooth muscle peturbed by PDGF, primary human bladder smooth muscle cells were treated with 1 nM PDGF-BB (hereafter PDGF) for 0, 4 or 24 h.

Project description:Context: Increased uterine stretch appears to increase the risk of preterm labour, but the mechanism is unknown. Objectives: To identify a targetable mechanism mediating the effect of stretch on human myometrium. Design: Myometrial explants, prepared from biopsies obtained at elective caesarean delivery, were either studied acutely, or were maintained in prolonged culture (up to 65 h) under tension with either a 0.6 g or 2.4 g mass, and compared using in vitro contractility, whole genome array, and qRT-PCR. Results: Increased stretch for 24 or 65 h increased potassium-induced and oxytocin-induced contractility. Gene array identified 62 differentially expressed transcripts after 65 h exposure to increased stretch. Two probes for gastrin-releasing peptide (GRP), a known stimulatory agonist of smooth muscle, were among the top five up-regulated by stretch (3.4-fold and 2.0-fold). Up-regulation of GRP by stretch was confirmed in a separate series of 10 samples using qRT-PCR (2.8-fold, P = 0.01). GRP stimulated contractions acutely when added to freshly obtained myometrial strips in 3 out of 9 cases, but Western blot demonstrated expression of the GRP receptor in 9 out of 9 cases. Prolonged incubation of stretched explants in the GRP antagonists PD-176252 or RC-3095 (65 and 24 h respectively) significantly reduced potassium chloride and oxytocin-induced contractility. Conclusion: Stretch of human myometrium increases contractility and stimulates the expression of a known smooth muscle stimulatory agonist, GRP. Incubation of myometrium in GRP receptor antagonists ameliorates the effect of stretch. GRP may be a target for novel therapies to reduce the risk of preterm birth in multiple pregnancy. 9 paired samples of human myometrium cultured under low (0.6g) or high (2.4g) tension

Project description:We assessed the pivotal effect of YAP on the proliferation of human bladder smooth muscle cells (hBdSMCs) under different ECM stiffnesses. We investigated the interaction between YAP and Smad3 through mass spectrometry and immunoprecipitation (IP). Transcriptome sequencing was used to predict the phenotype and signalling pathways. CUT and TAG sequencing was utilized to analyse the target genes of Smad3, and a dual-luciferase reporter assay was used to confirm the sequencing results. The YAP inhibitor CA3 was used in a partial bladder outlet obstruction (pBOO) rat model construction to evaluate bladder smooth muscle proliferation in vivo.
