TOP STORY
Yin and Yang: Immune Signaling Protein Has Opposing Roles in Breast Cancer Development
Researchers have discovered that inhibiting the immune receptor protein TLR4 may not be a wise treatment strategy in all cancers. This is because TLR4 can either promote or inhibit breast cancer cell growth depending on mutations in a gene called TP53.

LABORATORY RESEARCH

CCL2-Induced Chemokine Cascade Promotes Breast Cancer Metastasis by Enhancing Retention of Metastasis-Associated Macrophages
Scientists demonstrated that, through activation of the CC-chemokine ligand 2 (CCL2) receptor CCR2, the recruited metastasis-associated macrophages (MAMs) secrete another chemokine ligand CCL3. Genetic deletion of CCL3 or its receptor CCR1 in macrophages reduces the number of lung metastasis foci, as well as the number of MAMs accumulated in tumor-challenged lung in mice.

The Chemokine Receptor CCR6 Facilitates the Onset of Mammary Neoplasia in the MMTV-PyMT Mouse Model via Recruitment of Tumor-Promoting Macrophages
To establish if CCR6 plays a functional role in mammary tumorigenesis, a bigenic MMTV-PyMT CCR6-null mouse was generated and mammary tumor development was assessed. Levels of tumor-infiltrating immune cells within tumor-bearing mammary glands from MMTV-PyMT Ccr6WT and Ccr6-/- mice were also analyzed. [Mol Cancer] Full Article

miR-503 Inhibited Cell Proliferation of Human Breast Cancer Cells by Suppressing CCND1 Expression
The authors aimed to elucidate the role of miR-503 in the pathogenesis of breast cancer. Their results suggested that miR-503 expression was markedly downregulated in breast cancer tissues and cells. [Tumor Biol] Abstract

Hispolon Inhibits the Growth of Estrogen Receptor Positive Human Breast Cancer Cells through Modulation of Estrogen Receptor Alpha
The authors investigated the effects of Hispolon on the growth of breast cancer cells. They found that Hispolon decreased expression of estrogen receptor α at both mRNA and the protein levels in MCF7 and T47D human breast cancer cells. [Biochem Biophys Res Commun] Abstract

Myoepithelial and Luminal Breast Cancer Cells Exhibit Different Responses to All-trans Retinoic Acid
Investigators evaluated whether retinoids may differentially regulate cell type-specific processes associated with breast cancer development using the bi-cellular LM38-LP murine mammary adenocarcinoma cell line as a model. [Cell Oncol] Abstract

Kruppel-Like Factor 4 Signals through MicroRNA-206 to Promote Tumor Initiation and Cell Survival
Researchers found that both expand to Kruppel-like factor 4 and a downstream effector, microRNA-206, are selectively enriched in the mammary cancer stem-like cell (MaCSC) fractions of cultured human triple-negative breast cancer cell lines, as well as in the aldehyde dehydrogenase-high MaCSC sub-population of cells derived from xenografted human mammary carcinomas.

CLINICAL RESEARCH

Randomized Phase III Trial of Paclitaxel Once per Week Compared with Nanoparticle Albumin-Bound Nab-Paclitaxel Once per Week or Ixabepilone with Bevacizumab as First-Line Chemotherapy for Locally Recurrent or Metastatic Breast Cancer: CALGB 40502/NCCTG N063H (Alliance)
Investigators compared nab-paclitaxel or ixabepilone once per week to paclitaxel with bevacizumab as first-line therapy for patients with advanced breast cancer to evaluate progression-free survival for nab-paclitaxel or ixabepilone versus paclitaxel. [J Clin Oncol] Abstract

Patients with Slowly Proliferative Early Breast Cancer Have Low Five-Year Recurrence Rates in a Phase III Adjuvant Trial of Capecitabine
Researchers conducted a randomized Phase III study to determine whether patients with early breast cancer would benefit from the addition of capecitabine to a standard regimen of doxorubicin plus cyclophosphamide followed by docetaxel. [Clin Cancer Res] Abstract

REVIEWS
The Molecular, Cellular and Clinical Consequences of Targeting the Estrogen Receptor following Estrogen Deprivation Therapy
The current understanding of the mechanism of estrogen-induced apoptosis is described as a consequence of acquired resistance to long term antihormone therapy in estrogen receptor positive breast cancer. [Mol Cell Endocrinol] Abstract
