(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) 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) By survival analysis of breast cancer patients, JMJD6 was found to be significantly associated with poor prognosis. Over-expression and knock-down of JMJD6 in breast cancer cell lines suggested a role in proliferation. In order to study the transcriptional events that occur following JMJD6 expression changes, siRNA-mediated knock-down of JMJD6 was performed in MCF-7 and MDA-MB231 and stable over-expression of JMJD6 was performed in MCF-7.

(Submitter supplied) JMJD6 (also known as PTDSR) is an important oncogene that is upregulated in 17q21-ter gained neuroblastoma.It plays a role in E2F and N-Myc-regulated gene pathways and neuroblastoma tumorigenesis Using ChIP-Seq, we profiled JMJD6 and NMYC binding in the NMYC overexpressing neuroblastoma cell line. We identified the genomic location of JMJD6 and NMYC binding peaks across the human genome.

(Submitter supplied) Super-enhancers are defined by peaks in H3K27 acetylation and H3K4 mono-methylation, and the lack of H3K4 tri-methylation. They have been found to play a role in oncogene transcription and tumour maintenance. Using ChIP-Seq, we profiled H3K27ac, H3K4me and H3K4me3 binding in CHP-134 neuroblastoma cells. We identified H3K27ac, H3K4me and H3K4me3 binding sites in the CHP-134 neuroblastoma cell line.

(Submitter supplied) RNA samples were prepared from freshly sorted mammary cell subpopulations (MaSC/basal-enriched, luminal progenitor, mature luminal and stromal) from five sets of adult mice. High throughput RT-PCR was used to measure the global microRNA expression profiles of each cell subpopulation. The expression profiles were compared between cell subpopulations to gain insight into the regulation of lineage-restricted genes.

(Submitter supplied) A transgenic mouse model, MMTV-Wnt/ILK, with mammary specific expression of both Wnt-1 and ILK, was generated by crossing the two mouse lines MMTV-Wnt-1 and MMTV-ILK. Affymetrix Mouse Exon chips were hybridized with material from four independent mammary tumors from each MMTV-Wnt-1 and MMTV-Wnt/ILK transgenic model, in order to identify possible signaling differences involved during increased tumor incidence.

(Submitter supplied) The fibroblast growth factor pathway is known to cooperate with the highly oncogenic Wnt/beta-catenin pathway in mouse models of breast cancer. To investigate the mechanisms involved in this cooperativity, we utilized MMTV-driven transgenic mouse lines expressing a drug-inducible model for FGF Receptor signaling (iFGFR) crossed with the previously characterized MMTV-Wnt-1 mouse model. In these bigenic mice, both iFGFR1 and iFGFR2 activation resulted in a dramatic enhancement of mammary tumorigenesis. more...
