Androgen dependent gene expression profiling of the urogenital sinus

ABSTRACT: 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

Keywords: time course, prostate gland development Differential gene expression was assessed by direct comparisons of labeled moieties, using dye-swaps as technical replicates. Hybridizations were performed on the Agilent (Santa Clara, CA) Whole Mouse Genome DNA microarray (mgug4122a). Three different time points were analyzed using RNA pooled from different embryos: • UGS of female embryos upon 6 hours of androgen treatment compared to UGS of vehicletreated mice (H6 comparison, 8 different slides); • UGS of female embryos upon 12 hours of androgen treatment compared to UGS of vehicletreated mice (H12 comparison, 6 different slides); • UGS of male embryos compared to UGS of female embryos (MvsF comparison, 10 different slides). Pools from male tissues were hybridized against pools from female litter-mates;

Comparison of DNA methyltransferase-1 (Dnmt1) deleted urogenital sinus epithelium compared to wildtype urogenital sinus epithelium

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

Gene expression change induced by bisphenol A in mouse urogenital sinus

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. 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.

Transcription profiling of estradiol treated mouse fetal urogenital sinus mesenchyme cells

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 Î¼M estradiol .

Sox9 mediated differential gene expression was assessed in prostaspheres derived from urogenital sinus epithelial cells

Project description:Prostate cancer is one of the most common malignancies and the second leading cause of death from cancer in men. The molecular mechanisms driving prostate carcinogenesis are complex; with several lines of evidence suggesting that the re-expression of conserved developmental programs play a key role. Through conditional gene targeting and organ grafting, we describe conserved roles for the transcription factor Sox9 in the initiation of both prostate organogenesis and prostate carcinogenesis in murine models. Abrogation of Sox9 expression prior to the initiation of androgen signaling blocks the initiation of prostate development. Similarly, Sox9 deletion in two genetic models of prostate cancer (TRAMP and Hi-Myc) blocks cancer initiation. Expression profiling of Sox9-null prostate epithelial cells reveals that the role of Sox9 in the initiation of prostate development may relate to its regulation of multiple cytokeratins and/or calcium-related proteins. Due to its essential role in cancer initiation, manipulation of Sox9 targets in at-risk men may prove useful in the chemoprevention of prostate cancer. Sox9 differential gene expression in prostaspheres derived from the urogenital sinus epithelium was assessed by tow-colors direct comparisons of labeled moieties. Hybridizations were performed on the Agilent (Santa Clara, CA) Whole Mouse Genome DNA microarray (mgug4122a). Sox9 targets were assessed in murine prostate epithelial cells with targeted deletion.

Testosterone- and estrogen-induced genes in urogenital sinus mesenchyme

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.

Transcription profiling of mouse embryonic day 14 bladder, urogenital sinus, and urethra.

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.
