    Entinostat, Nivolumab and Ipilimumab for Women with Advanced HER2-Negative Breast Cancer: A Phase Ib Trial

    Investigators reported the results of 24 women, 50% with hormone receptor-positive breast cancer and 50% with advanced TNBC, treated with entinostat + nivolumab + ipilimumab from the dose escalation and expansion cohort of ETCTN-9844.

    A Novel Bystander Effect in Tamoxifen Treatment: PPIB Derived from ER+ Cells Attenuates ER− Cells via Endoplasmic Reticulum Stress-Induced Apoptosis

    Markable reductions were observed in tumorigenesis of estrogen receptor (ER)− breast cancer cells by applying both supernatants from Tamoxifen -treated ER+ cells and a transwell co-culture system, validating the presence of a TAM-induced bystander effect.

    A MAP1B–Cortactin–Tks5 Axis Regulates TNBC Invasion and Tumorigenesis

    Investigators found that MAP1B interacted with key components for invadopodia formation, cortactin, and Tks5, the latter of which was a PtdIns(3,4)PM2-binding and scaffold protein that localized to invadopodia.

    Dual-MicroRNA-Controlled Electrochemiluminescence Biosensor for Breast Cancer Diagnosis and Supplemental Identification of Breast Cancer Metastasis

    MicroRNA-21 was employed as a biomarker for breast cancer, and miR-21 induced the quenching of the electrochemiluminescence signal from luminophores via a strategically designed catalytic three-hairpin assembly circuit.

    An Inflamed Tumor Cell Subpopulation Promotes Chemotherapy Resistance in Triple Negative Breast Cancer

    To determine if transcriptional differences between tumor cells lead to differential drug responses, researchers performed single cell RNA-seq on cell line and PDX models of breast cancer revealing cell subpopulations in states associated with resistance to standard-of-care therapies.
