Skp2 Activates Cancer-Promoting, Glucose-Processing Akt
Scientists report that HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism. They also found that this chain of events promotes Herceptin resistance in breast cancer and activation of glucose metabolism.

CCR5 Antagonist Blocks Metastasis of Basal Breast Cancer Cells
This study provided evidence for the key role of CCL5/CCR5 in the invasiveness of basal breast cancer cells and suggested that CCR5 antagonists may be used as an adjuvant therapy to reduce the risk of metastasis in patients with the basal breast cancer subtype. [Cancer Res] Abstract

Claudin-2 Promotes Breast Cancer Liver Metastasis by Facilitating Tumor Cell Interactions with Hepatocytes
Researchers suggest that during breast cancer liver metastasis, claudin-2 shifts from acting within tight-junctional complexes to functioning as an adhesion molecule between breast cancer cells and hepatocytes. [Mol Cell Biol] Abstract

Loss of Plakoglobin Promotes Decreased Cell-Cell Contact, Increased Invasion and Breast Cancer Cell Dissemination In Vivo
Researchers demonstrated a functional role for plakoglobin in the shedding of tumor cells from the primary site into the circulation. [Breast Cancer Res] Abstract | Full Article

The Forkhead Box Transcription Factor FOXC1 Promotes Breast Cancer Invasion by Inducing Matrix Metalloprotease 7 (MMP7) Expression
Scientists demonstrated for the first time a correlation between MMP7 expression and basal-like breast cancers, suggesting that MMP7 may be a useful therapeutic target for treatment of this disease. [J Biol Chem] Abstract | Full Article

YAP Promotes Breast Cell Proliferation and Survival Partially through Stabilizing the KLF5 Transcription Factor
Investigators demonstrated that Yes-associated protein (YAP) functions partially through its binding to KLF5, a transcription factor that promotes breast cell proliferation and survival. [Am J Pathol] Abstract

Simultaneous Mitochondrial Ca2+ Overload and Proteasomal Inhibition are Responsible for the Induction of Paraptosis in Malignant Breast Cancer Cells
Scientists found that simultaneous inhibition of the mitochondrial Na+/Ca2+ exchanger and proteasomes can trigger a sustained mitochondrial Ca2+ overload and effectively induce paraptosis in malignant breast cancer cells. [Cancer Lett] Abstract

Methylseleninic Acid Restricts Tumor Growth in Nude Mice Model of Metastatic Breast Cancer Probably via Inhibiting Angiopoietin-2
Researchers investigated levels of angiopoietin-2 (Ang-2) and vascular endothelial growth factor on the estrogen-independent bone metastatic mammary cancer cells in response to treatment by methylseleninic acid. [BMC Cancer] Abstract | Full Article

Metformin Elicits Anticancer Effects through the Sequential Modulation of DICER and c-MYC
Researchers found that metformin affects engraftment and growth of breast cancer tumors in mice. They also demonstrated that microRNA modulation underlies the anticancer metabolic actions of metformin. [Nat Commun] Abstract


Safety Results from a Phase III Study (TURANDOT Trial by CECOG) of First-Line Bevacizumab in Combination with Capecitabine or Paclitaxel for HER-2-Negative Locally Recurrent or Metastatic Breast Cancer
Researchers report safety data from a randomized, phase III study evaluating first-line bevacizumab plus paclitaxel or capecitabine for locally recurrent or metastatic breast cancer. [Eur J Cancer] Abstract

Chromosome Instability and Benefit from Adjuvant Anthracyclines in Breast Cancer
Investigators used fluorescent in situ hybridization for chromosomes 1, 7, 11, 17 and 18 to identify patients with high percentages of tumor chromosome instability in the 322 patients recruited into the BR9601 clinical trial. [Br J Cancer] Abstract

Global MicroRNA Expression Profiling of High-Risk ER+ Breast Cancers from Patients Receiving Adjuvant Tamoxifen Mono-Therapy: A DBCG Study
Scientists identified a sub-group of Tamoxifen-treated breast cancer patients with microRNA-expressing tumors associated with cancer stem cell characteristics. [PLoS One] Full Article

Horizon 2020: A €80 Billion Battlefield for Open Access
As negotiations proceed to shape the next installment of Europe’s gargantuan research funding programs, scientists, librarians, and publishers are eagerly awaiting the answer to a critical question: How strong will the new seven-year program, called Horizon 2020, be on Open Access?
