    miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway

    Taichi Isobe et al.
    Insights into the roles and mechanisms of two of the miRNAs upregulated in human breast cancer stem cells in at least some breast cancers are presented.

    The selective estrogen receptor downregulator GDC-0810 is efficacious in diverse models of ER+ breast cancer

    James D Joseph et al.
    GDC-0810 is a novel, orally bioavailable SERD that exhibits robust pre-clinical activity in models of ER+ breast cancer, including models of tamoxifen resistance, and those that express the ERα mutations, ER.Y537S and ER.D538G.

    Estrogen receptor coregulator binding modulators (ERXs) effectively target estrogen receptor positive human breast cancers

    Ganesh V Raj et al.
    A novel first-in-class small molecule (ERX-11) that interacts with and disrupts the interactome of the estrogen receptor (ER), blocks the growth of ER-positive breast cancers, including those that are resistant to currently approved hormonal agents.

    PTEN and DNA-PK determine sensitivity and recovery in response to WEE1 inhibition in human breast cancer

    Andrä Brunner et al.
    DNA-PK and PTEN protect breast cancer cells from lethal replication stress induced by the WEE1 inhibitor AZD1775 and constitute new potential biomarkers for AZD1775 sensitivity.

    LARP7 suppresses P-TEFb activity to inhibit breast cancer progression and metastasis

    Xiaodan Ji et al.
    Transcription elongation by the elongation factor P-TEFb promotes the epithelial–mesenchymal transition and metastasis of breast cancer cells, implicating inhibition of this factor as a potential treatment for the late stages of this cancer.

    Three-dimensional growth of breast cancer cells potentiates the anti-tumor effects of unacylated ghrelin and AZP-531

    CheukMan C Au et al.
    3D culture of breast cancer in biologically relevant ECM potentiates the growth-inhibitory effects of unacylated ghrelin and AZP-531, and clinical response may be predictable based on a MAPK gene signature.

    The SERM/SERD bazedoxifene disrupts ESR1 helix 12 to overcome acquired hormone resistance in breast cancer cells

    Sean W Fanning et al.
    Bazedoxifene's SERD activities enable it to resist the impact of activating ESR1 mutations in breast cancer.

    Premature polyadenylation of MAGI3 produces a dominantly-acting oncogene in human breast cancer

    Thomas K Ni, Charlotte Kuperwasser
    The study of a recurrent breast cancer MAGI3 truncation reveals the role of MAGI3 in regulating the Hippo effector YAP and highlights premature mRNA cleavage and polyadenylation as a mechanism underlying cancer development.

    MELK is an oncogenic kinase essential for mitotic progression in basal-like breast cancer cells

    Yubao Wang et al.
    Maternal embryonic leucine zipper kinase (MELK) is a new anti-cancer target that is highly selective for basal-like breast cancer.

    Mechanism and preclinical prevention of increased breast cancer risk caused by pregnancy

    Svasti Haricharan et al.
    The transcription factor STAT5 mediates the increased breast cancer risk associated with a late age pregnancy, but intermittent anti-STAT5 treatment can lower this risk and thus prevent breast cancer.
