    SCIENCE NEWS

    Hormone Combination Effective in Metastatic Breast Cancer

[Press release from ModernMedicine discussing online prepublication in the Journal of Clinical Oncology]

    Study Finds Diet and Alcohol Alter Epigenetics of Breast Cancer and Could Predict Severity of Disease

    LABORATORY RESEARCH

    Rb Deletion in Mouse Mammary Progenitors Induces Luminal-B or Basal-Like/EMT Tumor Subtypes Depending on p53 Status

    Telomerase-Immortalized Human Mammary Stem/Progenitor Cells with Ability to Self-Renew and Differentiate
    Researchers presented evidence that normal and human telomerase reverse transcriptase-immortalized human mammary epithelial cells isolated and maintained in Dana-Farber Cancer Institute 1 medium retain a fraction with progenitor cell properties. [ Proc Natl Acad Sci USA]

    Reprogramming Human Cancer Cells in the Mouse Mammary Gland
    Here, investigators reported that human embryonal carcinoma cells proliferate and produce differentiated mammary epithelial cell progeny when mixed with mouse mammary epithelial cells and inoculated into the epithelium-free mammary fat pads of athymic nude mice. [Cancer Res]

    The Relationship Between Terminal Functionalization and Molecular Weight of a Gene Delivery Polymer and Transfection Efficacy in Mammary Epithelial 2-D Cultures and 3-D Organotypic Cultures
    Non-viral gene delivery vectors were developed for efficient gene transfer to hard-to-transfect mouse mammary epithelial cells. Ten modified versions of the same base poly(beta-amino ester), poly(1,4-butanediol diacrylate-co-5-amino-1-pentanol), were tested in both traditional 2-D monolayer and in 3-D organotypic cultures. [Biomaterials]

    Rb Inactivation Accelerates Neoplastic Growth and Substitutes for Recurrent Amplification of cIAP1, cIAP2 and Yap1 in Sporadic Mammary Carcinoma Associated with p53 Deficiency

    Cacalol, a Natural Sesquiterpene, Induces Apoptosis in Breast Cancer Cells by Modulating Akt-SREBP-FAS Signaling Pathway
    In this report, investigators demonstrated that cacalol has strong anti-proliferation effect on breast cancer cells and induces apoptosis by activating a pro-apoptotic pathway. [Breast Cancer Res Treat]

    Plasmonics Nanoprobes: Detection of Single-Nucleotide Polymorphisms in the Breast Cancer BRCA1 Gene
    This paper described the application of plasmonics-based nanoprobes that combine the modulation of the plasmonics effect to change the surface-enhanced Raman scattering of a Raman label and the specificity of a DNA hairpin loop sequence to recognize and discriminate a variety of molecular target sequences. [Anal Bioanal Chem]


    Ferroportin and Iron Regulation in Breast Cancer Progression and Prognosis
    Scientists demonstrated that both ferroportin and hepcidin are expressed in cultured human breast epithelial cells and that hepcidin regulates ferroportin in these cells. [Sci Transl Med]

    CLINICAL RESEARCH

    Phase II Trial of Anastrozole Plus Goserelin in the Treatment of Hormone Receptor-Positive, Metastatic Carcinoma of the Breast in Premenopausal Women
    The purpose of this study was to explore the antitumor activity of the aromatase inhibitor, anastrozole, in the treatment of premenopausal women with hormone receptor-positive, metastatic breast cancer who have been rendered functionally postmenopausal with the use of the luteinizing hormone-releasing hormone agonist, goserelin. [J Clin Oncol]

    Breast Cancer DNA Methylation Profiles Are Associated with Tumor Size and Alcohol and Folate Intake
    Using primary breast tumors from 162 (American Joint Committee on Cancer stage I-IV) women from the Kaiser Division of Research Pathways Study and the Illumina GoldenGate methylation bead-array platform, researchers measured 1,413 autosomal CpG loci associated with 773 cancer-related genes and validated select CpG loci with Sequenom EpiTYPER. [PLoS Genet]
