    PMN-MDSCs Modulated by CCL20 from Cancer Cells Promoted Breast Cancer Cell Stemness through CXCL2-CXCR2 Pathway

    Investigators observed that polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) were remarkably enriched in the tumor microenvironment of CCL20-overexpressing cancer cell orthotopic allograft tumors.

    PIN1 and CDK1 Cooperatively Govern pVHL Stability and Suppressive Functions

    Researchers identified cyclin-dependent kinase 1 (CDK1) and peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) as two previously uncharacterized regulators of protein von Hippel–Lindau (pVHL) in multiple types of human cancers harboring wild-type VHL, including TNBC.

    Notch3 Regulates Mybl2 via HeyL to Limit Proliferation and Tumor Initiation in Breast Cancer

    The authors investigated expression of Notch3 in human breast cancer samples and effects of its loss in mice. Notch3 expression was very weak in breast cancer cells and was associated with good patient prognosis.

    Phytocannabinoids in Triple Negative Breast Cancer Treatment: Current Knowledge and Future Insights

    Pre-clinical studies highlighted various antitumor activities of plant-derived Cannabis sativa and synthetic cannabinoids (CBs). However, some studies indicated that CBs might also promote tumor progression. The authors review known and possible interactions between cannabinoids and TNBC therapies.
