Analysis of mammary glands of 5 and 10-week-old bitransgenics overexpressing oncogenic ErbB2/Neu and luteinizing hormone (LH). Results provide insight into the effect of chronic trophic maintenance of the mammary epithelial cells, induced by LH, on ErbB2/Neu-initiated tumorigenesis.

(Submitter supplied) CDC25A is a critical target of checkpoint, and its overexpression is observed in various cancers. Here we demonstrate that in vivo levels of Cdc25A expression determine the efficiency of transformation and tumorigenesis. Transgenic expression of CDC25A in murine mammary glands cooperates with tumorigenesis induced by expression of ras or neu. CDC25A- overexpressing tumors display aggressiveness and genomic instability with changes in fragile chromosomal regions, including the region orthologous to human 1p32-36. more...

(Submitter supplied) The complexity of gene regulation has created obstacles to defining mechanisms that establish the patterns of gene expression characteristic of the different clinical phenotypes of breast cancer. Transcription factor TFAP2C plays a critical role in the regulation of both estrogen receptor-alpha (ERα) and c-ErbB2/HER2 (Her2). Herein, we performed chromatin immunoprecipitation and direct sequencing (ChIP-seq) for TFAP2C in four breast cancer cell lines representing different clinical phenotypes. more...

(Submitter supplied) ErbB-2 overexpression and amplification occurs in 15 - 30% of human invasive breast carcinomas associated with poor clinical prognosis. Previously, we have demonstrated that four ErbB-2/Neu tyrosine-autophosphorylation sites within the cytoplasmic tail of the receptor recruit distinct adaptor proteins and are sufficient to mediate transforming signals in vitro. Two of these sites representing the Grb2 (Neu-YB) and Shc (Neu-YD) binding sites can induce mammary tumourigenesis and metastasis. more...

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) 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...

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.
