    Exosomal DEK Removes Chemoradiotherapy Resistance by Triggering Quiescence Exit of Breast Cancer Stem Cells

    Researchers identified and isolated chemoradiotherapy-resistant cancer stem cells in quiescent state with high capacity of tumor-initiation and tumorsphere formation from three types of breast tumors in mice.

    Abstract

    miR-10b-5p-Mediated Upregulation of PIEZO1 Predicts Poor Prognosis and Links to Purine Metabolism in Breast Cancer

    Investigators elucidated an important role of PIEZO1 in breast cancer and provided key clues for identifying PIEZO1 as a therapeutic target and prognostic biomarker in breast cancer.

    Sulforaphane Suppresses Metastasis of Triple-Negative Breast Cancer Cells by Targeting the RAF/MEK/ERK Pathway

    The authors showed that sulforaphane (SFN), including its two isomers of R-SFN and S-SFN, significantly inhibited transforming growth factor-β1-induced migration and invasion in breast cancer cells.

    Abstract

    mTOR Inhibition and Trastuzumab-Emtansine (T-DM1) in HER2-Positive Breast Cancer

    Everolimus in combination with T-DM1 showed strong antitumor effects in HER2-positive breast cancer, both in vitro and in vivo.

    Abstract

    Inhibition of Triple Negative Breast Cancer-Associated Inflammation, Tumor Growth and Brain Colonization by Targeting Monoacylglycerol Lipase

    Scientists targeted Monoacylglycerol lipase (MAGL) in TNBCs, using a potent carbamate-based inhibitor AM9928 with prolonged pharmacodynamic effects. AM9928 blocked TNBC cell adhesion and transmigration across human brain microvascular endothelial cells in 3D co-cultures.

    Abstract

    MCL-1 Is a Clinically Targetable Vulnerability in Breast Cancer

    On-target compounds specific to MCL-1 have demonstrated promising efficacy in preclinical models of breast cancer and show potential to enhance the anti-tumor effect of conventional therapies.
