Gene expression analyses of PR action in the mammary gland of ovariectomized mice

ABSTRACT: Beyond demonstrating a critical role for progesterone receptor signaling in normal mammary epithelial proliferation, the progesterone receptor knockout mouse disclosed the progesterone receptor along with its effector pathways as key determinants of mammary neoplastic progression. Despite these advances, however, further progress in our mechanistic understanding of progesterone’s involvement in mammary morphogenesis and tumorigenesis is contingent upon defining the essential effector pathways responsible for transducing the progesterone signal into a mammary proliferative and/or pro-survival response. Toward this goal, a judiciously chosen acute progesterone treatment regimen together with microarray methods was applied to the mammary gland of the normal mouse to uncover new effectors that operate immediately downstream of the progesterone mammary signal. Examination of the resultant progesterone-responsive transcriptome disclosed “inhibitor of differentiation or DNA binding 4” (Id4) as a molecular target acutely induced by progesterone in the murine mammary epithelium.

Transcription profiling of mammary tissue from ovariectomized mice previously treated with progesterone for 4, 16, 28, and 76 hours

Project description:Beyond demonstrating a critical role for progesterone receptor signaling in normal mammary epithelial proliferation, the progesterone receptor knockout mouse disclosed the progesterone receptor along with its effector pathways as key determinants of mammary neoplastic progression. Despite these advances, however, further progress in our mechanistic understanding of progesteroneâ??s involvement in mammary morphogenesis and tumorigenesis is contingent upon defining the essential effector pathways responsible for transducing the progesterone signal into a mammary proliferative and/or pro-survival response. Toward this goal, a judiciously chosen acute progesterone treatment regimen together with microarray methods was applied to the mammary gland of the normal mouse to uncover new effectors that operate immediately downstream of the progesterone mammary signal. Examination of the resultant progesterone-responsive transcriptome disclosed â??inhibitor of differentiation or DNA binding 4â?? (Id4) as a molecular target acutely induced by progesterone in the murine mammary epithelium. Experiment Overall Design: Microarray analysis was performed on mammary tissue total RNA obtained from ovariectomized mice previously treated with progesterone for 4, 16, 28, and 76 hours. For each hormone treatment time-point, mammary gland microarray data from sesame oil (vehicle) treated mice was included as controls. Total mammary gland RNA from each time-point and treatment group was interrogated using the Affymetrix GeneChip Mouse Genome 430 2.0 Array. For a given time-point and treatment group, three sets of mice (5 mice in each set) were used for gene expression profiling; mammary RNA pooled from each set was hybridized to one microarray chip. Therefore, a total of 15 mice (or 3 microarray chips) were used per time-point and treatment group.

Inhibitor of Differentiation 4 (ID4) represses myoepithelial differentiation of mammary stem cells through its interaction with HEB

Project description:Differentiation of stem cells embedded within the mammary epithelium is orchestrated by lineage-specifying transcription factors. Unlike the well-defined luminal hierarchy, dissection of the basal lineage has been hindered by a lack of specific markers. Inhibitor of Differentiation 4 (ID4) is a basally-restricted helix-loop-helix (HLH) transcription factor essential for mammary development. Here we show that ID4 is highly expressed in basal stem cells and decreases during myoepithelial differentiation. By integrating transcriptomic, proteomic and chromatin-association data we reveal that ID4 is required to suppress myoepithelial gene expression and cell fate.

RNA-seq of ID4 knockdown Comma-Dβ mammary epithelial cells

Project description:The goal of this study was to determine the genes regulated by ID4 in mammary epithelial cells. ID4 was knocked down by siRNA in the mammary epithelial cell line Comma-Dβ and RNA-seq was performed following 48 hr to determine differentially expressed genes.

RNA-seq of FACS-enriched mammary subpopulations (basal, luminal progenitor, mature luminal) from WT and ID4 knockout mice

Project description:The goal of this study was to determine the genes regulated by ID4 in mammary epithelial subpopulations. Basal, luminal progenitor, and mature luminal mammary epithelial subpopulations were FACS-sorted from adult mice that were either WT or ID4 KO in quadruplicate. RNA-seq and differential gene expression analysis was performed.

Progesterone receptor-dependent gene signatures in the mouse mammary gland after acute progesterone treatment

Project description:Progesterone (P) acting through its cognate nuclear receptors (PRs) plays an essential role in driving pregnancy-associated branching morphogenesis of the mammary gland. However, the fundamental mechanisms, including global cistromic and acute genomic transcriptional responses that are required to elicit active branching morphogenesis in response to P, have not been elucidated. We used microarray analysis to identify global gene expression signatures that are acutely regulated by PRs in the mouse mammary gland after acute P treatment. Mammary gland gene expression data from 10-week-old ovariectomized wildtype and progesterone receptor null mice treated subcutaneously with 17β-Estradiol for 24 hours and then 17β-Estradiol plus Progesterone for 8 or 24 hours. Three replicate pools were tested with three mice per pool.

Mammary molecular portraits reveal lineage-specific features and progenitor cell vulnerabilities

Project description:The mammary epithelium depends on specific lineages and their stem and progenitor function to accommodate hormone-triggered physiological demands in the adult female. Perturbations of these lineages underpin breast cancer risk, yet our understanding of normal mammary cell composition is incomplete. Here, we build a multimodal resource for the adult gland through comprehensive profiling of primary cell epigenomes, transcriptomes, and proteomes. We define systems-level relationships between chromatin–DNA–RNA–protein states, identify lineage-specific DNA methylation of transcription factor binding sites, and pinpoint proteins underlying progesterone responsiveness. Comparative proteomics of estrogen and progesterone receptor–positive and –negative cell populations, extensive target validation, and drug testing lead to discovery of stem and progenitor cell vulnerabilities. Top epigenetic drugs exert cytostatic effects; prevent adult mammary cell expansion, clonogenicity, and mammopoiesis; and deplete stem cell frequency. Select drugs also abrogate human breast progenitor cell activity in normal and high-risk patient samples. This integrative computational and functional study provides fundamental insight into mammary lineage and stem cell biology. PMID: 29921600 (Table S5 and Table S7)
