LABORATORY RESEARCH

Direct Regulation of MicroRNA Biogenesis and Expression by Estrogen Receptor ß in Hormone-Responsive Breast Cancer
Considering the possibility that estrogen receptor ß (ERß) might influence breast cancer (BC) cell behavior via microRNAs (miRNAs), researchers compared miRNome expression in ERß+ vs ERß- hormone-responsive BC cells and found a widespread effect of this ER subtype on the expression pattern of these non-coding RNAs. [Oncogene] Abstract

Hyperinsulinemia Enhances c-Myc-Mediated Mammary Tumor Development and Advances Metastatic Progression to the Lung in a Mouse Model of Type II Diabetes
Using a hyperinsulinemic mouse model and the metastatic, c-Myc-transformed mammary carcinoma cell line Mvt1, researchers investigated how high systemic insulin levels would affect the progression of orthotopically inoculated primary mammary tumors to lung metastases. [Breast Cancer Res] Abstract

Hypoxia Inducible Factor-1α Promotes Primary Tumor Growth and Tumor-Initiating Cell Activity in Breast Cancer
Researchers investigated whether hypoxia inducible factor-1α is directly implicated in regulation of tumor-initiating cells in breast cancer. [Breast Cancer Res] Abstract

Microcalcifications in Breast Cancer: Novel Insights into the Molecular Mechanism and Functional Consequence of Mammary Mineralization
Researchers report a novel model to investigate the in vitro mineralization potential of a panel of mammary cell lines. [Br J Cancer] Abstract

Impaired CK1δ Activity Attenuates SV40-Induced Cellular Transformation In Vitro and Mouse Mammary Carcinogenesis In Vivo
Here researchers characterized the effects of mutant CK1δ variants with impaired kinase activity on simian virus 40 (SV40)-induced cell transformation in vitro, and on SV40-induced mammary carcinogenesis in vivo in a transgenic/bi-transgenic mouse model. [PLoS One] Abstract

Small Interfering RNA Targeted to IGF-IR Delays Tumor Growth and Induces Proinflammatory Cytokines in a Mouse Breast Cancer Model
The aim of this study was to determine whether an RNA interference approach targeted to insulin-like growth factor-1 receptor (IGF-IR) could be used for specific antitumor immunostimulation in a breast cancer model. [PLoS One] Abstract

Bone Morphogenetic Protein (BMP) Signaling Regulates Mitotic Checkpoint Protein Levels in Human Breast Cancer Cells
In the present study researchers show that, in human breast cancer cells, chemical inhibition of BMPs, but not transforming growth factor-β, abrogates the mitotic arrest induced by nocodazole. [Cell Signal] Abstract

EphrinA1-EphA2 Interaction-Mediated Apoptosis and FMS-Like Tyrosine Kinase Receptor Ligand-Induced Immunotherapy Inhibits Tumor Growth in a Breast Cancer Mouse Model
Researchers tested the EphrinA1-EphA2 interaction in MDA-MB-231 breast cancer cells focusing on the receptor-ligand-mediated apoptosis of breast cancer cells. [J Gene Med] Abstract

CLINICAL RESEARCH

Estrogen Metabolism and Risk of Breast Cancer in Postmenopausal Women
In this study, researchers found nearly all estrogens, estrogen metabolites, and metabolic pathway groups were associated with an increased risk of breast cancer; the serum concentration of unconjugated estradiol was strongly associated with the risk of breast cancer. [J Natl Cancer Inst] Abstract

Novel Genetic Markers of Breast Cancer Survival Identified by a Genome-Wide Association Study
Here researchers report the identification of two SNPs associated with total mortality from a two-stage genome-wide association study conducted among 6,110 Shanghai-resident Chinese women with TNM stage I-IV breast cancer. [Cancer Res] Abstract
