    Targeting HER2-AXL Heterodimerization to Overcome Resistance to HER2 Blockade in Breast Cancer

    The authors identified AXL overexpression as an essential mechanism of trastuzumab resistance. AXL orchestrated epithelial-to-mesenchymal transition and heterodimerized with HER2, leading to activation of PI3K/AKT and MAPK pathways in a ligand-independent manner.

    TRAF4 Inhibits the Apoptosis and Promotes the Proliferation of Breast Cancer Cells by Inhibiting the Ubiquitination of Spindle Assembly-Associated Protein Eg5

    Scientists demonstrated that tumor necrosis factor receptor associated factor 4 (TRAF4) regulated Eg5 ubiquitination and contributed to Eg5-mediated breast cancer proliferation and inhibited breast cancer apoptosis.

    Targeting Aberrant Replication and DNA Repair Events for Treating Breast Cancers

    Investigators reported a small molecule, Carbazole Blue, that bound itself to DNA and inhibited cancer growth and metastasis by targeting DNA-related processes that tumor cells use but not the normal cells.

    GPR110 Promotes Progression and Metastasis of Triple-Negative Breast Cancer

    Researchers found that G-protein-coupled receptor 110 (GPR110) was highly expressed in TNBC and GPR110 played a key role in TNBC progression by engaging the RAS signaling pathway, via Gαs activation.

    HMGB1 Mediates Invasion and PD-L1 Expression through RAGE-PI3K/AKT Signaling Pathway in MDA-MB-231 Breast Cancer Cells

    Scientists investigated the mechanism of high-mobility group box 1 (HMGB1) through receptors for advanced glycation end products (RAGE) on cell migration/invasion and programmed death ligand 1 (PD-L1) expression in breast cancer cells.
