2015-06-26 | GSE70271 | GEO

Expression data from mammary tumors from a MOLF/Ei x PyMT mouse cross

Project description:Mouse genetic crosses were established between the PyMT model of metastatic breast cancer and MOLF/Ei strain. Tumors were harvested from the animals for gene expression analysis to identify genes associated with progression to distant metastatic disease. Gene expression of 134 samples from the MOLF cross were assayed on Affymetrix chips.

caArray_green-00030: 2-methoxyestradiol (2ME2) induces mammary gland differentiation through amphiregulin-EGFR mediated signaling

Project description:2-methoxyestradiol (2ME2) induces mammary gland differentiation through amphiregulin-EGFR mediated signaling: molecular distinctions from the mammary gland of pregnant mice.High levels of 2ME2 are observed in the late stages of pregnancy. We investigated the role of 2ME2 on normal mammary gland development. Large scale gene expression assays were performed using Affymetrix GeneChips in pursuit of detailed molecular basis. (1) Mammary glands of wild type FVB mice administered 75 or 150 mg/kg of 2ME2 (2) Mammary glands of normal FVB/Nj mice (i) at day 16 of pregnancy, (ii) day 2 of lactation (iii) day 30 of post-lactation, and (3) mammary epithelial SCp2 cells after 6, 24 and 48 hours of 10 micromol 2ME2 treatment were examined. In vivo studies revealed that 2ME2 treatment up regulates the expression of amphiregulin. The clue to the role of 2ME2 in differentiation comes from studies in vitro which detected down regulation of inhibitor of differentiation (Id-1) gene and consequent up regulation of amphiregulin. The differentiation of E2 negative SCp2 cells by 2ME2 indicate estradiol independent mechanism. For details, please see our paper in Endocrinology 2006. **NOTE: Migrated from caArray 1.x, identifier='gov.nih.nci.ncicb.caarray:Experiment:1015897590892008:1'

Differential gene regulation downstream of murine Tmem173 variants

Project description:We report positional cloning and characterization of a novel Sting allele that fails to activate IFN production in the wild-derived mice of MOLF/Ei strain in response to HSV (Herpes Simplex Virus) and Listeria monocytogenes both in vitro and in vivo. We show that previously uncharacterized mutations in the N-terminal of STING are responsible for low levels of IFN due to failure of MOLF STING to respond to cytosolic STING agonists such as 2’3’cGAMP, 5,6-Dimethylxanthenone-4-acetic acid (DMXAA) or poly(deoxyadenylic-deoxythymidylic) acid (dAdT). Using Next-Generation Sequencing (NGS) for the analysis of DNA-responses in congenic C57BL6.StingMOLF/MOLF (MOLF STING) mouse macrophages, we show that these mutations in MOLF/Ei discriminate in responses between different STING agonists. Macrophages from C57BL6.StingB6/B6¬ (B6 STING), or B6 STING expressing littermates were stimulated as a positive control for STING activation, and STING -/- (STING KO) macrophages served as a negative control.

Transcription profiling of mouse AKR/J x PyMT F1 versus DBA/2J x PyMT F1 tumors

Project description:F1 hybrids from (AKR/J x FVB/NJ) and (DBA/2J x FVB/NJ) outcrosses display a 20-fold difference in mammary tumor metastatic capacity, due to differences in inherited polymorphisms. Expression studies were performed to determine whether polymorphism-driven gene expression signatures predictive of outcome could be generated from mouse tumor tissues Experiment Overall Design: Mammary tumors from adult F1 animals from (AKR/J x PyMT) and (DBA/2J x PyMT) outcrosses was collected and arrayed on Affymetrics chip to identify basal differences in gene expression between the different genotypes

caArray_gray-00215: A collection of breast cancer cell lines for the study of functionally distinct cancer subtypes

Project description:Recent studies suggest that thousands of genes may contribute to breast cancer pathophysiologies when deregulated by genomic or epigenomic events. Here, we describe a model system to appraise the functional contributions of these genes to breast cancer subsets. In general, the recurrent genomic and transcriptional characteristics of 51 breast cancer cell lines mirror those of 145 primary breast tumors, although some significant differences are documented. The cell lines that comprise the system also exhibit the substantial genomic, transcriptional, and biological heterogeneity found in primary tumors. We show, using Trastuzumab (Herceptin) monotherapy as an example, that the system can be used to identify molecular features that predict or indicate response to targeted therapies or other physiological perturbations. **NOTE: Migrated from caArray 1.x, identifier='gov.nih.nci.ncicb.caarray:Experiment:1015897590151581:1'
