    Oncogenic Action of the Exosome Cofactor RBM7 by Stabilization of CDK1 mRNA in Breast Cancer

    In vitro, experiments revealed that knockdown of RNA binding motif protein 7 (RBM7) dramatically inhibited breast cancer cell proliferation, while inducing G1 cell cycle arrest; the opposite was true when RBM7 was overexpressed.

    Novel Aza-Podophyllotoxin Derivative Induces Oxidative Phosphorylation and Cell Death via AMPK Activation in Triple-Negative Breast Cancer

    The authors developed and characterized the efficacy of novel AMPK activator that selectively induced oxidative phosphorylation and decreased glycolysis in TNBC cells, while not affecting these pathways in normal cells.

    Insulin Receptor Substrate-1 (IRS-1) Mediates Progesterone Receptor-Driven Stemness and Endocrine Resistance in Oestrogen Receptor+ Breast Cancer

    The transcriptomes of primary tumors and metastases in mice harboring estrogen receptor+ breast cancer patient-derived xenografts were analyzed following single-cell RNAseq. In vitro assays were employed to delineate mechanisms of endocrine resistance and stemness.

    Combined Treatment of Mitoxantrone Sensitizes Breast Cancer Cells to Rapalogs through Blocking eEF-2K-Mediated Activation of Akt and Autophagy

    Scientists found that eEF-2K, which was overexpressed in cancer cells and was required for survival of stressed cells, was involved in the negative-feedback activation of Akt and cytoprotective autophagy induction in breast cancer cells in response to mTOR inhibitors.

    Efficacy Based Ginger Fingerprinting Reveals Potential Antiproliferative Analytes for Triple Negative Breast Cancer

    Researchers characterized the fingerprint profiles of 22 ginger samples using liquid chromatography-mass spectroscopy, followed by a principal component analysis and pearson correlation analysis. They also evaluated the anti-proliferative effects of these samples on TNBC cells using the MTT assays.
