Project description:The goal of this experiment was to determine if testosterone (T) and estradiol-17 beta (E2) induced gene expression in mouse urogenital sinus mesenchymal (UGM) cells. When UGM grown in culture was treated with T+E2, numerous genes were increased and decreased compared to untreated controls. Quantitative RT-PCR was used to verify results of a subset of genes. UGM cells were untreated or treated with T+E2 for 72hrs. One mouse gene expression array was used for each group.

Project description:Developmental estrogen exposure causes permanent alterations to mouse prostate development. Fetal prostatic mesenchyme cells regulate epithelial cell proliferation and differentiation, and alterations to mesenchymal regulation of prostate epithelial cell proliferation and differentiation may lead to permanent changes in gland structure and function. Our goal was to understand how mesenchymal cells convert estrogen signaling to stimuli that affect epithelial cells. We used microarrays to identify estrogen-induced transcriptomal changes in primary cultures of fetal mouse prostate mesenchymal cells. Experiment Overall Design: Urogenital sinus mesenchymal cells were obtained from CD-1 male mouse fetuses at gestation day 17 and cultured in the presence of 0.1 μM estradiol .

Project description:Dnmt1 is an important regulator of tissue development and differentiation. To assess the effects of epithelium Dnmt1 deletion in the developing urogenital sinus (precursor of the urethra and prostate in males), we isolated urogenital sinus epithelial tissue from Dnmt1 deleted mouse embryos and wildtype mouse embryos. The transcriptomes were analyzed by RNA-seq

Project description:Developmental exposure of mouse fetuses to estrogens results in dose-dependent permanent effects on prostate morphology and function. Fetal prostatic mesenchyme cells express estrogen receptor alpha (ERα) and androgen receptors and convert stimuli from estrogens and androgens into signaling to regulate epithelial cell proliferation and differentiation. To obtain mechanistic insight into the role of different doses of estradiol (E2) in regulating mesenchymal cells, we examined E2-induced transcriptomal changes in primary cultures of fetal mouse prostate mesenchymal cells. Urogenital sinus mesenchyme cells were obtained from male mouse fetuses at gestation day 17 and exposed to 10 pM, 100 pM or 100 nM E2 in the presence of a physiological concentration of dihydrotestosterone (0.69 nM) for four days. Gene ontology studies suggested that low doses of E2 (10 pM and 100 pM) induce genes involved in cell adhesion, morphological tissue development, and sterol biosynthesis but suppress genes involved in growth factor signaling and cell adhesion. Genes showing inverted-U-shape dose responses (enhanced by E2 at 10 pM E2 but suppressed at 100 pM) were identified, and their enrichment in the glycolytic pathway was demonstrated. At the highest dose (100 nM), E2 induced genes enriched not only for cell adhesion but also steroid hormone signaling and metabolism, cytokines and their receptors, cell-to-cell communication, Wnt signaling, and TGF-β signaling. These results suggest that prostate mesenchymal cells may regulate epithelial cells through direct cell contacts when estrogen level is low whereas soluble growth factors might play significant roles when estrogen level is high. Primary culture urogenital sinus mesenchymal cells were isolated from prostate glands of gestation day 17 CD1 male mouse fetuses. Cells were then exposed to 10 pM or 100 pM 17beta-estradiol or vehicle (0.05% ethanol) for four days in the presence of 690 pM 5alpha-dihydrotestosterone. Total cellular RNA was then isolated for determination of transcriptomal profiles by Affymetrix mouse gene 1.0 ST array.

Project description:Bisphenol A (BPA), an endocrine-disrupting chemical (EDC), is a well-known, ubiquitous estrogenic chemical. To investigate the effects of fetal exposure to low-dose BPA on the development of the prostate, we first examined the alterations of in situ sex steroid hormonal environment in the mouse urogenital sinus (UGS). Next, to investigate the BPA-specific gene alterations related to increases of the E2 levels and aromatase activity, we performed comprehensive gene expression analysis using Affymetrix GeneChip in the BPA-treated or DES-treated male UGS at embryonic day 17th and postnatal day 1st.

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing bladder. The central thesis is straightforward. The combination ofmicrodissected and laser capture microdissection (LCM) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing urogenital system. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. The data submitted here represents the gene expression profiles of the embryonic day 14 bladder, urogenital sinus, and urethra. Experiment Overall Design: Bladder, urogenital sinus, and urethra regions from embryonic day 14 SMGA/EGFP animals were microdissected and total RNA isolated for gene expression analysis using the Affymetrix MOE430 microarray chip.

Pregnant female C57BL/6 mice were exposed to BPA (20 μg/kg/day) or synthetic estrogen Diethylstilbestrol (DES: 0.2 μg/kg/day), which were dissolved in tocopherol-stripped corn oil, on embryonic day 13 (E13) to E16. Between E17 and postnatal day 1 (P1), all animals were terminated by an overdose of isoflurane followed by cervical dislocation. Fetuses were collected at E17, E18, P0, and P1. The bladder and urethra were removed and dissected to isolate UGS and collected in RNA later. To isolate pure UGS, other tissues such as the bladder, urethra, Wolffian duct (WD), seminal vesicle (SV), and Mullerian duct (MD) were removed from both the male and female urogenital tracts. The histopathology of the mouse UGS was then examined by hematoxylin and eosin staining. Total RNA was extracted using the Qiagen mini RNA Easy kit. Each RNAs were linearly amplified and hybridized to Affymetrix GeneChip.

Project description:Cancer cells differentiate along specific lineages that largely determine their clinical and biologic behavior. Distinct cancer phenotypes from different cells and organs likely result from unique gene expression repertoires established during lineage commitment in the embryo and maintained after malignant transformation. We used comprehensive gene expression analysis to examine this concept in the prostate, an organ with a readily manipulable developmental program and a high propensity for cancer. We focused on gene expression changes in the murine prostate rudiment (Urogenital Sinus, UGS) at three time points during the first 48 hours of exposure to androgen, which initiates proliferation and invasion of prostate epithelial buds into surrounding mesenchyme. Keywords: time course, prostate gland development
