    ZMYND8 Is a Master Regulator of 27-Hydroxycholesterol that Promotes Tumorigenicity of Breast Cancer Stem Cells

    Researchers showed that the histone reader ZMYND8 was selectively expressed in breast cancer stem cells (BCSCs) and promoted epithelial-mesenchymal transition, BCSC maintenance and self-renewal, and oncogenic transformation through its epigenetic functions, leading to breast tumor initiation.

    Autocrine Pro-Legumain Promotes Breast Cancer Metastasis via Binding to Integrin αvβ3

    The authors reported that legumain (LGMN) was secreted in the zymogen form by motile breast cancer cells. The autocrine pro-LGMN activated FAK-Src-RhoA signaling in cancer cells and promoted cancer cell migration and invasion independent of LGMN protease activity.

    Loss-of-Function of the Hippo Transducer TAZ Reduces Mammary Tumor Growth through a Myeloid-Derived Suppressor Cell-Dependent Mechanism

    Researchers found that TAZ knockdown in two murine triple-negative breast cancer tumor cell line models significantly inhibited tumor growth and metastasis in immune competent but not immune deficient hosts.
