Circulating Tumor Cells Provide Genomic Snapshot of Breast Cancer
Tumor cells isolated from the blood of patients with triple negative breast cancer reveal similar cancer-driving mutations as those detected from standard biopsy, suggesting that circulating cells could one day replace tissue biopsies.

Densely Ionizing Radiation Acts via the Microenvironment to Promote Aggressive Trp53 Null Mammary Carcinomas
Densely ionizing radiation has potentially greater carcinogenic effect compared to sparsely ionizing radiation that is prevalent on earth. Investigators used a radiation chimera in which mice were exposed to densely ionizing 350 MeV/amu Si-particles, gamma-radiation, or sham-irradiated and transplanted three days later with syngeneic Trp53 null mammary fragments. [Cancer Res] Abstract

Fra-1/AP-1 Induces EMT in Mammary Epithelial Cells by Modulating Zeb1/2 and TGFβ Expression
Ectopic expression of Fra-1 in fully polarized, non-tumorigenic, mouse mammary epithelial EpH4 cells induced a mesenchymal phenotype, characterized by a loss of epithelial and gain of mesenchymal markers. Proliferation, motility and invasiveness were also increased in the resulting EpFra1 cells, and the cells were tumorigenic and efficiently colonized the lung upon transplantation. [Cell Death Differ] Abstract

Direct Incorporation of the NKT-Cell Activator α-Galactosylceramide into a Recombinant Listeria monocytogenes Improves Breast Cancer Vaccine Efficacy
Researchers analyzed whether the natural killer T (NKT) cell-activating glycolipid α-galactosylceramide could overcome immune suppression and improve vaccination against metastatic breast cancer. [Br J Cancer] Abstract

Spontaneous Dormancy of Metastatic Breast Cancer Cells in an All Human Liver Microphysiologic System
The authors describe a human ex vivo hepatic microphysiologic system. Breast cancer cells intercalate into the hepatic niche without interfering with hepatocyte function. Examination of cancer cells demonstrated that a significant subset enter a quiescent state of dormancy as shown by lack of cell cycling. [Br J Cancer] Abstract

Curcumin Inhibits Breast Cancer Stem Cell Migration by Amplifying the E-Cadherin/Beta-Catenin Negative Feedback Loop
Curcumin, a plant ployphenol, has several anti-tumor effects and has been shown to target cancer stem cells (CSCs). Researchers evaluated the mechanisms underlying the aggravated migration potential of breast CSCs and the effects of curcumin in modulating the same. [Stem Cell Res Ther] Abstract | Full Article

Characterization of β2-Microglobulin Expression in Different Types of Breast Cancer
Researchers characterized β2-microglobulin (β2-M) expression in molecular subtypes of breast cancer, thereby investigating the mechanism of β2-M action in breast cancer. [BMC Cancer] Full Article


Statin Use after Diagnosis of Breast Cancer and Survival: A Population-Based Cohort Study
Preclinical studies have shown that statins, particularly simvastatin, can prevent growth in breast cancer cell lines and animal models. Scientists investigated whether statins used after breast cancer diagnosis reduced the risk of breast cancer-specific, or all-cause, mortality in a large cohort of breast cancer patients. [Epidemiology] Abstract

IL6 Genotype, Tumor ER-Status, and Treatment Predicted Disease-Free Survival in a Prospective Breast Cancer Cohort
Researchers investigated the association between interleukin-6 (IL6) genotypes, estrogen receptor (ER)-status, and treatment on the risk of early events among breast cancer patients. [BMC Cancer] Full Article

An Update on PARP Inhibitors – Moving to the Adjuvant Setting
The authors describe the evolution of poly(ADP-ribose) polymerase (PARP) inhibitors from bench to bedside, and provide an up-to-date description of the key published or otherwise reported clinical trials of these agents. The specific considerations and challenges that might be encountered when implementing these compounds in the adjuvant treatment of breast cancer in the clinic are also highlighted.

The Breast Cancer Research Foundation Commits Record $58.6 Million in Research Grants
The Breast Cancer Research Foundation (BCRF) announced its dedication of $58.6 million to breast cancer research. Totaling $47 million, the 2014-2015 annual grants, awarded to more than 220 physicians and scientists on six continents, continue to fuel BCRF’s mission of advancing the world’s most innovative research.
