    MYC Is a Clinically Significant Driver of mTOR Inhibitor Resistance in Breast Cancer

    Researchers showed that MYC activation drove resistance to mTOR inhibitors in breast cancer. MYC status was significantly associated with poor response to everolimus therapy in metastatic breast cancer patients.

    SPDEF Enhances Cancer Stem Cell-Like Properties and Tumorigenesis through Directly Promoting GALNT7 Transcription in Luminal Breast Cancer

    The expressions and clinicopathological characteristics of SAM pointed domain containing ETS transcription factor (SPDEF) in luminal breast cancer patients were evaluated bioinformatically.

    EIF4A3-Mediated circ_0042881 Activates the RAS Pathway via miR-217/SOS1 Axis to Facilitate Breast Cancer Progression

    The authors investigated the clinical implications and underlying mechanisms of circ_0042881 in breast cancer (BC). Functionally, circ_0042881 significantly accelerated the proliferation, migration, and invasion of BC cells in vitro and tumor growth and metastasis in vivo.

    A Combination of a Cell Penetrating Peptide and a Protein Translation Inhibitor Kills Metastatic Breast Cancer Cells

    Scientists reported that Nutrient Autophagy Factor 1 was efficient in killing BT-549, Hs 578T, MDA-MB-436, and MDA-MB-453 breast cancer cells, but that MDA-MB-157 cells were resistant to it.

    DEPDC1B-Mediated USP5 Deubiquitination of β-Catenin Promotes Breast Cancer Metastasis by Activating the Wnt/β-Catenin Pathway

    The authors found that DEPDC1B was highly expressed in breast cancer cells and tissues and was associated with lower overall survival in patients.

    Abstract

    Increased RUNX3 Expression Mediates Tumor-Promoting Ability of Human Breast Cancer-Associated Fibroblasts

    Researchers found that the exp-cancer-associated fibroblasts highly expressed Runt-related transcription factor 3 (RUNX3), while counterpart fibroblasts did not.

    Effect of 2-Methoxyestradiol Treatment on Early- and Late-Stage Breast Cancer Progression in a Mouse Model

    Scientists compared the effect of 2-methoxyestradiol in early- and late-stage breast cancer using a transgenic mouse model—FVB/N-Tg—of spontaneously development of aggressive mammary carcinoma with lung metastasis.

    The Role of Mitochondrial/Metabolic Axis in Development of Tamoxifen Resistance in Breast Cancer

    The authors investigate the possible role of the metabolic/hypoxial axis LncRNA taurine up-regulated 1, miR-186, sirtuin-3, peroxisome proliferator activator receptor alpha, and hypoxia-inducible factor-1 in the development of tamoxifen resistance in breast cancer patients.
