TOP STORY

Master Gene SRC-3 Enables Breast Cancer Growth, Invasion
The master gene called steroid receptor coactivator 3 not only enhances estrogen-dependent growth of cancer cells by activating and encouraging the transcription of a genetic message into a protein, it also sends a signal to the cell membrane to promote cell motility or movement. [Press release from the Baylor College of Medicine discussing online prepublication in Molecular Cell]

SCIENCE NEWS

Study Reveals Genetic Link between Mammographic Density and Breast Cancer
The study revealed that certain breast cancer genetic variants increase mammographic density, confirming the link between mammographic breast density and breast cancer. [Press release from EurekAlert! discussing online prepublication in Cancer Research]

GUMC Researchers Say Flower Power May Reduce Resistance to Breast Cancer Drug Tamoxifen
Combining tamoxifen, the world’s most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug.  [Press release from the Georgetown Lombardi Comprehensive Cancer Center discussing online prepublication in FASEB J]

CURRENT PUBLICATIONS

LABORATORY RESEARCH

SRC-3(Delta)4 Mediates the Interaction of EGFR with FAK to Promote Cell Migration
Findings identify phosphorylated SRC-3(delta)4 as a missing adaptor between EGFR and its downstream signaling molecule FAK to coordinately regulate EGF-induced cell migration. [Mol Cell]

Vitamin D Deficiency Promotes Human Breast Cancer Growth in a Murine Model of Bone Metastasis
Study concluded that vitamin D deficiency promotes the growth of human breast cancer cells in the bones of nude mice. [Cancer Res]

An RNA Interference Screen Identifies Metabolic Regulators NR1D1 and PBP as Novel Survival Factors for Breast Cancer Cells with the ERBB2 Signature
Research showed that ERBB2-positive breast cancer cells are genetically preprogrammed to depend on NR1D1 and PBP for the energy production necessary for survival. [Cancer Res]

A Potential Tumor Suppressor Role for Hic1 in Breast Cancer Through Transcriptional Repression of Ephrin-A1
Hypermethylated in cancer 1 (HIC 1) spatially restricts ephrin-A1 expression in development, and that upregulated expression of ephrin-A1 resulting from epigenetic silencing of HIC1 in cancer cells may be an important mechanism in epithelial malignancy. [Oncogene]

BCL2 and CASP8 Regulation by NF-(kappa)B Differentially Affect Mitochondrial Function and Cell Fate in Antiestrogen-Sensitive and -Resistant Breast Cancer Cells
Data provide significant new insights into how molecular signaling affects antiestrogen responsiveness and strongly suggest that a combination of parthenolide and tamoxifen may offer a novel therapeutic approach to the management of some ER-positive breast cancers [FASEB J]

Delineating Genetic Alterations for Tumor Progression in the MCF10A Series of Breast Cancer Cell Lines
Genetic analyses uncovered sequential molecular events that delineate breast tumor progression. These events include CDKN2A deletion and MYC amplification in immortalization, HRAS activation in transformation, PIK3CA activation in the formation of malignant tumors, and RUNX1 deletion associated with poorly-differentiated malignant tumors. [PLoS One]


CLINICAL RESEARCH

Aspirin Intake and Survival After Breast Cancer
Among women living at least 1 year after a breast cancer diagnosis, aspirin use was associated with a decreased risk of distant recurrence and breast cancer death. [J Clin Oncol]

Alberta Physical Activity and Breast Cancer Prevention Trial: Sex Hormone Changes in a Year-Long Exercise Intervention Among Postmenopausal Women
This trial found that previously sedentary postmenopausal women can adhere to a moderate- to vigorous-intensity exercise program that results in changes in estradiol and sex hormone-binding globulin concentrations that are consistent with a lower risk for postmenopausal breast cancer. [ J Clin Oncol]

Multiplexed Assessment of the Southwest Oncology Group-Directed Intergroup Breast Cancer Trial S9313 by AQUA Shows That Both High and Low Levels of HER2 Are Associated with Poor Outcome
In patients who were uniformly treated with doxorubicin and cyclophosphamide chemotherapy and tamoxifen, both estrogen receptor and progesterone receptor, assessed as continuous variables, were highly prognostic, whereas p53 expression was not. [Am J Pathol]

Micrometastatic Node-Positive Breast Cancer: Long-Term Outcomes and Identification of High-Risk Subsets in a Large Population-Based Series
The number of positive nodes and the lymph node ratio should be considered in conjunction with tumor factors in risk estimates and treatment decisions for patients with nodal micrometastatic breast cancer. [Ann Surg Oncol]




INDUSTRY NEWS

Newfoundland and Labrador Breast Cancer Test Victims Win $17.5M Settlement
The Supreme Court of Newfoundland and Labrador has approved a $17.5-million settlement in a class-action lawsuit launched by hundreds of patients whose breast cancer tests were botched. [CTV News]

Safeway Gives another $317,000 for TGen Breast Cancer Research
Even with unemployment high and sales down, Safeway Inc. has donated more than $317,000 to fund breast cancer research. [Translational Genomics Research Institute Press Release]
