(Submitter supplied) The objective of this study was to determine the effect of Thyroid Hormone Responsive Protein Spot14 (Spot14) loss on the gene expression profiles of tumors from MMTV-Polyomavirus middle-T antigen (PyMT) mice. MMTV-PyMT/S14-heterozygous mice were crossed with S14-heterozygous mice and 1 cm tumors from MMTV-PyMT control (wild-type S14) or MMTV-PyMT/S14-null offspring were profiled using Affymetrix gene arrays. more...

(Submitter supplied) The objective of this study was to determine the effect of Thyroid Hormone Responsive Protein Spot14 (Spot14) overexpression on the gene expression profiles of tumors from MMTV-Neu mice. Hemizygous MMTV-Neu and MMTV-Spot14 mice were bred and 1 cm tumors from Neu control or Neu/Spot14 bitransgenic offspring were profiled using Affymetrix gene arrays. Tumors from Neu/Spot14 mice emerged significantly earlier than controls, but expressed many genes associated with lactogenic differentiation and were not highly metastatic. more...

(Submitter supplied) MicroRNAs (miRNAs) are small, non-coding, endogenous RNAs involved in many human diseases including breast cancer. miRNA expression profiling of human breast cancers has identified miRNAs related to the clinical diversity of the disease and potentially provides novel diagnostic and prognostic tools for breast cancer therapy. In order to further understand the roles of miRNAs in association with oncogenic drivers and in specifying sub-types of breast cancer, we performed miRNAexpression profiling on mammary tumors from eight well-characterized genetically -engineered Mouse (GEM) models of human breast cancer including MMTV–H-Ras, -Her2/neu, -c-Myc, -PymT, –Wnt1 and C3(1)/SV40 T/t-antigen transgenic mice, BRCA1fl/fl;p53+/-;MMTV-cre and the p53fl/fl ;MMTV-cre transplant model.

(Submitter supplied) We performed affymetrix gene expression profiling on mammary tumors from eight well-characterized genetically engineered Mouse (GEM) models of human breast cancer. The gene expression data will be combined with the miRNA gene expression data from the corresponding mammary tumors and tissues for integrated miRNA and mRNA gene expression analysis, which are useful in improving the identification of miRNA targets from potential targets identified in silico.

(Submitter supplied) Background. Oncogene overexpression in primary cells often triggers the induction of a cellular safeguard response promoting senescence or apoptosis. Secondary cooperating genetic events are generally required for oncogene induced tumorigenesis to overcome these biologic obstacles. We employed array CGH for 8 genetically-engineered mouse models of mammary cancer to identify loci that might harbor genes that enhance oncogene-induced tumorigenesis. more...

(Submitter supplied) Psoriasin (S100A7) has been shown to be highly expressed in invasive estrogen receptor negative breast cancers. Expression of S100A7 in human breast tumors represents a poor prognostic marker and correlates with lymphocyte infiltration in high-grade morphology. Recent studies have shown that S100A7 downregulation in ERα- cells lines inhibits tumor growth in in vivo mouse model systems. However, not much is known about its mechanisms in regulating breast cancers. more...

(Submitter supplied) Genome-wide analyses have identified thousands of long non-coding RNAs (lncRNAs). Malat1 (Metastasis Associated Lung Adenocarcinoma Transcript 1) is among the most abundant lncRNAs whose expression is altered in numerous cancers. Here we report that genomic loss, as well as systemic knockdown of Malat1 using antisense oligonucleotides, in the MMTV-PyMT mouse mammary carcinoma model results in slower tumor growth accompanied by differentiation into highly cystic tumors and a significant reduction in lung metastasis. more...
