    Time-Restricted Feeding Normalizes Hyperinsulinemia to Inhibit Breast Cancer in Obese Postmenopausal Mouse Models

    Scientists tested a time-restricted feeding (TRF) approach on mouse models of obesity-driven postmenopausal breast cancer. They showed that TRF abrogated the obesity-enhanced mammary tumor growth in two orthotopic models in the absence of calorie restriction or weight loss.

    Mesenchymal Stem Cell-Secreted Extracellular Vesicles Instruct Stepwise Dedifferentiation of Breast Cancer Cells Into Dormancy at the Bone Marrow Perivascular Region

    Investigators addressed the early period of dormancy when breast cancer cells enter bone marrow at the perivascular region to begin the transition into cancer stem cells, which they proposed as the final step in dormancy.

    Abstract

    Serine Biosynthesis Is a Metabolic Vulnerability in IDH2-Driven Breast Cancer Progression

    Researchers explored the association of breast cancer subtypes with different metabolic phenotypes and identified isocitrate dehydrogenase 2 (IDH2) as a key player in TNBC and HER2.

    Abstract

    Tumor-Suppressor Function of Beclin 1 in Breast Cancer Cells Requires E-Cadherin

    The authors performed a genome-wide CRISPR/Cas9 screen in MCF7 breast cancer cells to identify genes whose loss of function reversed Beclin 1-dependent inhibition of cellular proliferation.

    Functional Hierarchy and Cooperation of EMT Master Transcription Factors in Breast Cancer Metastasis

    Scientists provided strong evidence that epithelial-to-mesenchymal transition (EMT) was orchestrated by coordinated expression of several EMT- transcription factors and established ZEB1 as a key master regulator of EMT and metastasis in breast cancer.

    Abstract

    Decorin-Mediated Suppression of Tumorigenesis, Invasion, and Metastasis in Inflammatory Breast Cancer

    Overexpression of decorin in inflammatory breast cancer (IBC) cells markedly decreased migration, invasion, and cancer stem cells in vitro and inhibited tumor growth and metastasis in IBC xenograft mouse models.

    Single-Cell Long Noncoding RNA (lncRNA) Transcriptome Implicates MALAT1 in Triple-Negative Breast Cancer (TNBC) Resistance to Neoadjuvant Chemotherapy

    The authors identified the lncRNA transcriptional landscape associated with TNBC resistance to neoadjuvant chemotherapy, employing 1758 single cells from three extinction and three persistence TNBC patients.

    Valerian and Valeric Acid Inhibit Growth of Breast Cancer Cells Possibly by Mediating Epigenetic Modifications

    Researchers tested the hypothesis that the circadian-related herb valerian could inhibit breast cancer cell growth and explored epigenetic changes associated with valeric acid treatment.
