    ZFP281 Drives a Mesenchymal-Like Dormancy Program in Early Disseminated Breast Cancer Cells That Prevents Metastatic Outgrowth in the Lung

    Researchers revealed at a single-cell resolution that mesenchymal-like and pluripotency-like programs coordinated dissemination and a long-lived dormancy program of early disseminated cancer cells.

    High p16 Expression and Heterozygous RB1 Loss Are Biomarkers for CDK4/6 Inhibitor Resistance in ER+ Breast Cancer

    The authors found that p16 overexpression was associated with reduced antitumor activity of CDK4/6 inhibitors in patient-derived xenografts and estrogen receptor-positive breast cancer cell lines.

    ROBO3s: A Novel ROBO3 Short Isoform Promoting Breast Cancer Aggressiveness

    Using transcriptomic and proteomic approaches in human and murine basal-like breast cancer cells (BLBC), scientists investigated the molecular mechanisms underlying aggressive and chemotherapy-resistant phenotypes in BLBC mammary tumors.

    Downregulation of Elovl5 Promotes Breast Cancer Metastasis Through a Lipid-Droplet Accumulation-Mediated Induction of TGF-β Receptors

    Researchers studied the elongation of very long-chain fatty acids protein 5 (Elovl5) in breast cancer.

    STING Agonism Enhances Anti-Tumor Immune Responses and Therapeutic Efficacy of PARP Inhibition in BRCA-Associated Breast Cancer

    Investigators demonstrated that compared to monotherapies, combined Poly (ADP-ribose) polymerase (PARP) inhibition and STING agonism resulted in increased STING pathway activation, greater cytotoxic T cell recruitment, and enhanced dendritic cell activation in BRCA1-deficient breast cancer models.

    Silencing TRAIP Suppresses Cell Proliferation and Migration/Invasion of Triple Negative Breast Cancer via RB-E2F Signaling and EMT

    Bioinformatic analysis, Western blot, immunohistochemistry, CCK-8, colony formation, flow cytometry, wound healing, Transwell, and dual-luciferase reporter assays were performed to explore the role of tumor necrosis factor receptor-related factor interacting protein (TRAIP) in TNBC.

    Multiomic Characterization and Drug Testing to Establish Circulating Tumor Cells as an Ex Vivo Tool for Personalized Medicine

    Scientists tested anti-cancer drugs on tumor cells from a metastatic breast cancer patient. Circulating tumor cell responses mirrored the impact of drugs on metastatic rather than primary tumors.

    Deletion of Mdig Enhances H3K36me3 and Metastatic Potential of the Triple Negative Breast Cancer Cells

    Using a mouse model of orthotopic xenograft of the TNBC MDA-MB-231 cells, researchers demonstrated that mineral dust-induced gene (mdig) promoted the growth of primary tumors but inhibited metastasis of these cells in vivo.

    Abstract

    Clinical Application of Advanced Multi-Omics Tumor Profiling: Shaping Precision Oncology of the Future

    The authors summarize the latest advances in multi-omics tumor profiling, focusing on spatial genomics and chromatin organization, spatial transcriptomics and proteomics, liquid biopsy, and ex vivo modeling of drug response.
