Analysis of ductal carcinoma in situ (DCIS) of mammary gland. DCIS represents an early, pre-invasive stage in development of invasive breast carcinoma. These results, together with results from a rodent model of DCIS development, provide insight into molecular basis of early stages of breast cancer.

(Submitter supplied) Murine healthy tissue samples, DCIS and invasive mammary tumors were analyzed in order to identify marker genes which show enhanced expresssion in DCIS and invasive ductal carcinomas. Using this approach, we were able to identify a set of genes which might allow a better detection of DCIS and invasive carcinomas in the future.

(Submitter supplied) To obtain insight into the molecular basis of ductal carcinoma in situ (DCIS) and its progression by infiltrating surrounding tissue, we have performed cellular-based gene expression analysis of pure DCIS and DCIS with co-existing invasive ductal carcinoma (IDC) and compared the histological and molecular aspects between these morphologically identical lesions seeking to find key genes involved in DCIS progression. more...

(Submitter supplied) Our study shows that TGF-β signaling promotes tumorigenesis in the liver through upregulation of its target gene, Snail. We explored gene expression changes in tumors following TGF-β inhibition, and tumors ectopically expressing Snail with the TGF-β inhibition. RNA samples were harvested from tumors expressing Smad7 (S7HP tumors), firefly luciferase (LHP tumors), and Smad7 plus Snail (S7HP+Snail), respectively. more...

(Submitter supplied) [original title] Metastatic Canine Mammary Carcinomas can be Identified by a Gene Expression Profile that partly Overlaps with Human Breast Cancer Profiles. Introduction: Similar to human breast cancer mammary tumors of the female dog are commonly associated with a fatal outcome due to the development of distant metastases. However, the molecular defects leading to metastasis are largely unknown and the value of canine mammary carcinoma as a model for human breast cancer is unclear. more...

(Submitter supplied) We have reported previously that in preclinical models, BMP4 is a potent inhibitor of breast cancer metastasis and that high BMP4 protein levels predict favourable patient outcome. Here, we investigated the requirement for functional SMAD4 in mediating the anti-metastatic response of BMP4, given reports of promotion of metastasis by BMP4 in cancers where SMAD4 is frequently deleted. BMP4-induced inhibition of metastasis does not require functional SMAD4 in tumor cells. more...

(Submitter supplied) Spontaneously occurring canine mammary cancer represents an excellent model of human breast cancer, but is greatly understudied. To better use this valuable resource, we performed whole-genome sequencing, whole-exome sequencing, RNA-seq, and/or high-density arrays on twelve canine mammary cancer cases, including seven simple carcinomas and four complex carcinomas. Canine simple carcinomas, which histologically match human breast carcinomas, harbor extensive genomic aberrations, many of which faithfully recapitulate key features of human breast cancer. more...

(Submitter supplied) Basal-like carcinoma is a subtype of breast cancer that is characterized by poor prognosis and high intratumor heterogeneity. Using a basal-like breast epithelial line, we have identified two anti-correlated gene-expression programs that arise among single extracellular matrix (ECM)-attached cells during organotypic 3D culture. The first program contains TGFBR3, a high-affinity receptor for transforming growth factor β (TGFβ) and other related ligands. more...
