TOP STORY

Beta1-Integrin is Dispensable for the Induction of ErbB2 Mammary Tumors but Plays a Critical Role in the Metastatic Phase of Tumor Progression  ShareThis
Previous studies with a polyomavirus middle T mammary tumor model have indicated that targeted disruption of beta1-integrin in the mammary glands of these mice completely blocks tumor induction. To further explore the general significance of these observations, researchers crossed these conditional beta1-integrin strains to a strain of mice carrying mouse mammary tumor virus/activated erbB2.

SCIENCE NEWS

UK Breast Cancer Mortality Rates Have Fallen Faster Than in Other European Countries, Study Finds
Population-based breast cancer mortality rates in the United Kingdom (UK) have fallen steeply in the last two decades — more than in any other major European country, finds a study. [Press release from ScienceDaily discussing online prepublication in the British Medical Journal]

Stark Differences in Global Breast Cancer Rates Underscore Role of US Lifestyle in Risk, Say Experts
Breast cancer rates in the United States are nearly double those seen in South American countries like Brazil, and experts said that differences in diet, weight and physical activity are important reasons why. [American Institute for Cancer Research Press Release]

LABORATORY RESEARCH

Core Epithelial-to-Mesenchymal Transition Interactome Gene-Expression Signature is Associated with Claudin-Low and Metaplastic Breast Cancer Subtypes
The epithelial-to-mesenchymal transition (EMT) core signature associates closely with the claudin-low and metaplastic breast cancer subtypes and correlates negatively with pathological complete response. Additionally, the expression level of FOXC1, another EMT inducer, correlates strongly with poor survival of breast cancer patients. [Proc Natl Acad Sci USA]

A Rac-Pak Signaling Pathway is Essential for ErbB2-Mediated Transformation of Human Breast Epithelial Cancer Cells
In this study, scientists asked if ErbB2 expression correlates with p21-activated kinase-1 (Pak1) and extracellular signal-regulated kinase activity in human breast cancer specimens, and if Pak1 signaling is required for ErbB2 transformation in a three-dimensional in vitro setting and in xenografts. [Oncogene]

Nox4-Dependent Ros Production by Stromal Mammary Cells Modulates Epithelial MCF-7 Cell Migration
In this work, investigators studied the influence of epithelial cells on the stromal redox status and the consequence of this phenomenon on MCF-7 cell motility. [Br J Cancer]

The Embryonic Transcription Cofactor LBH is a Direct Target of the Wnt Signaling Pathway in Epithelial Development and in Aggressive Basal Subtype Breast Cancers
Here researchers show that in epithelial development, limb-bud and heart (LBH) expression is tightly controlled by Wnt signaling. [Mol Cell Bio]

CD36-Mediated Activation of Endothelial Cell Apoptosis by an N-Terminal Recombinant Fragment of Thrombospondin-2 Inhibits Breast Cancer Growth and Metastasis In Vivo
Scientists generated a recombinant fusion protein consisting of the N-terminal region of thrombospondin-2 (TSP-2) and the IgG-Fc1 fragment (N-TSP2-Fc) and could demonstrate that the antiangiogenic activity of N-TSP2-Fc is dependent on the CD36 receptor. [Breast Cancer Res Treat]

Loss, Mutation and Deregulation of L3MBTL4 in Breast Cancers
Investigators studied 307 primary breast tumors and 47 breast cancer cell lines by high resolution array comparative genomic hybridization. They identified a region on 18p11.31 lost in about 20% of the tumors and 40% of the cell lines. [Mol Cancer]

Native Type IV Collagen Induces Cell Migration Through a CD9 and DDR1-Dependent Pathway in MDA-MB-231 Breast Cancer Cells
Researchers demonstrated here that native type IV collagen induces a transient increase of CD9-cell surface levels through a DDR1-dependent pathway in MDA-MB-231 breast cancer cells, as revealed by flow cytometry and Western blotting using specific antibodies that recognize CD9. [Eur J Cell Biol]

SLUG/SNAI2 and Tumor Necrosis Factor Generate Breast Cells with CD44+/CD24- Phenotype
Scientists hypothesized that only a subset of genes associated with epithelial-to-mesenchymal transition generates CD44+/CD24- cells. [BMC Cancer]

CLINICAL RESEARCH 

Disparities in Breast Cancer Mortality Trends Between 30 European Countries: Retrospective Trend Analysis of WHO Mortality Database
The objective of this study was to examine changes in temporal trends in breast cancer mortality in women living in 30 European countries. [Br Med J]

Case-Control Study of Body Size and Breast Cancer Risk in Nigerian Women
The authors assessed the association between breast cancer and anthropometric measures in the Nigerian Breast Cancer Study (Ibadan, Nigeria). [Am J Epidemiol]

Breast Cancer Patients’ Clinical Outcome Measures are Associated with Src Kinase Family Member Expression
This study determined mRNA expression levels for Src kinase family (SFK) members in breast tissue specimens and assessed protein expression levels of prominent SFK members in invasive breast cancer to establish associations with clinical outcome. [Br J Cancer]

Pfizer Inc. said a jury in Pennsylvania state court found that the hormone-therapy drug Prempo didn’t cause breast cancer in two women. [The Wall Street Journal]

Breast Tissue Model to Aid Research
University of Ulster researchers are to develop a 3D model of breast tissue using human cells, to examine some of the potential causes of breast cancer. The researchers at the Biomedical Sciences Research Institute received £360,000 funding from The National Centre for the Replacement, Refinement and Reduction of Animals in Research to carry out the project, which will develop a model of human tissue to explore breast cancer, rather than the current animal testing carried out. [University of Ulster Press Release]

International Recognition for IUPUI Work to Improve Breast Cancer Detection
A paper describing the development of a new methodology to improve identification of breast cancer tissue by pathology laboratories has been selected as the best scientific paper in the “bioinformatics and biomedical applications track” by the International Association for Pattern Recognition. [Indiana University-Purdue University Indianapolis (IUPUI) Press Release]
