    The PTX3/TLR4 Autocrine Loop as a Novel Therapeutic Target in Triple Negative Breast Cancer

    To understand the effects of pentraxin-3 (PTX3) in TNBC, different cell lines were engineered to knock-down or overexpress PTX3. The contribution of tumor and stromal cells to PTX3 production in TNBC was also assessed.

    Abstract

    ILT4 Reprograms Glucose Metabolism to Promote Tumor Progression in Triple-Negative Breast Cancer

    Researchers found that TNBC displayed the most abundant immunoglobulin-like transcript 4 (ILT4) expression among all breast cancer subtypes.

    Abstract

    Suppression of Migration and Invasion by Taraxerol in the Triple-Negative Breast Cancer Cell Line MDA-MB-231 via the ERK/Slug Axis

    Scientists evaluated the effects of taraxerol on the migration and invasion of MDA-MB-231 cells, analyzed the molecular mechanism through network pharmacology and molecular docking, and finally verified it by in vitro experiments.
