    TOP STORY

    Cell of Origin Identified for Common Type of Breast Cancer
    Researchers propose a new model for breast cell differentiation that identifies two populations of progenitor cells, one of which appears to be the cell of origin for luminal-like breast cancer, the most common form of the disease. [Tufts University, Boston]

    SCIENCE NEWS

    ‘Chattering’ Receptors Drive Breast Cancer
    Scientists have shown for the first time how preventing two receptors from communicating with each other can influence the activity of estrogen, the hormone that fuels the progression of breast cancer in many women. [Cancer Research United Kingdom, Cambridge]

    Breakthrough Breast Cancer Therapy Reduces Mastectomies
    A new treatment not only killed large breast cancer tumors, but reduced the need for mastectomies by almost 90 percent. [University of Oklahoma, Oklahoma City]

    LABORATORY RESEARCH

     Monoacylglycerol Lipase Regulates a Fatty Acid Network that Promotes Cancer Pathogenesis
    Researchers show that the enzyme monoacylglycerol lipase is highly expressed in aggressive human cancer cells and primary tumors, where it regulates a fatty acid network enriched in oncogenic signaling lipids that promotes migration, invasion, survival, and in vivo tumor growth. [Cell]

    Cyclin D1 Kinase Activity Is Required for the Self-Renewal of Mammary Stem and Progenitor Cells that Are Targets of MMTV-ErbB2 Tumorigenesis
    Using a kinase-deficient cyclin D1 mouse, researchers identified two functional mammary progenitor cell populations, one of which is the target of MMTV-ErbB2. [Cancer Cell]

    Regulation of Breast Cancer Stem Cell Activity by Signaling through the Notch4 Receptor
    The findings suggest that Notch4-targeted therapies will be more effective than targeting Notch1 in suppressing breast cancer recurrence, as it is initiated by breast cancer stem cells. [Cancer Res]

    Heterogeneity of Gene Expression in Stromal Fibroblasts of Human Breast Carcinomas and Normal Breast
         Carcinoma-associated fibroblasts (CAF) support and promote tumorigenesis, whereas normal mammary fibroblasts (NF) are thought to suppress tumor progression. Little is known about the difference in gene expression between CAF and NF or the patient-to-patient variability in gene expression. [Oncogene]

    Cooperative Interaction Between Retinoic Acid Receptor-Alpha and Estrogen Receptor in Breast Cancer
         Retinoic acid receptor-alpha is required for efficient estrogen receptor-alpha-mediated transcription and cell proliferation. [Genes Dev]

    Glypican-3 Reexpression Regulates Apoptosis in Murine Adenocarcinoma Mammary Cells Modulating PI3K/Akt and p38MAPK Signaling Pathways
    Glypican-3 inhibits the PI3K/Akt anti-apoptotic pathway while it stimulates the p38MAPK stress-activated pathway. [Breast Cancer Res Treat]

    CLINICAL RESEARCH

    Phase II Trial of Primary Systemic Therapy with Doxorubicin and Docetaxel Followed by Surgery, Radiotherapy, and Adjuvant Chemotherapy with Cyclophosphamide, Methotrexate, and 5-Fluorouracil Based on Clinical and Pathologic Response in Patients with Stage IIB to III Breast Cancer : Long-Term Results from The University of Texas M. D. Anderson Cancer Center Study ID97-099
    This study was performed to evaluate the outcomes of patients with locally advanced breast cancer who were treated with a multidisciplinary approach including primary systemic chemotherapy and noncross-resistant adjuvant chemotherapy. [Cancer]

    A Phase 1B Dose Escalation Trial of Scutellaria barbata (BZL101) for Patients with Metastatic Breast Cancer
    The study concluded that the oral administration of BZL101 was safe, well tolerated, and showed promising clinical evidence of anticancer activity in this heavily pretreated population of women with metastatic breast cancer. [Breast Cancer Res Treat]

    INDUSTRY NEWS

    Bionovo Announces Publication of Positive Results From the Phase 1B Clinical Trial of Bezielle (BZL101) for Metastatic Breast Cancer
    The results demonstrate that Bezielle continues to be safe and well tolerated with clinical evidence of anticancer activity in a heavily pretreated population of women diagnosed with metastatic breast cancer. [Bionovo Inc. Press Release]

    Medifocus, Inc. Announces Its Breast Cancer Treatment is Getting Nationwide Coverage after Positive Clinical Results Published in Annals of Surgical Oncology: Results Indicate Potentially Reducing the Need for Mastectomy
    Medifocus, Inc. is pleased to announce that a review article summarizing clinical studies of the Company’s Microfocus APA 1000 Breast Cancer Thermotherapy System was published online. [Medifocus, Inc. Press Release]
