    TOP STORY

    Identification of a Minority Population of LMO2+ Breast Cancer Cells that Integrate into the Vasculature and Initiate Metastasis

    LMO2 knockdown in human breast tumors reduced lung metastasis by impairing intravasation, leading to a reduced frequency of circulating tumor cells.

    Abstract

    Superenhancer Drives a Tumor-Specific Splicing Variant of MARCO to Promote Triple-Negative Breast Cancer Progression

    Scientists presented a comprehensive analysis of RNA splicing in breast cancer to illustrate the biological function and clinical implications of tumor-specific transcripts arising from these splicing junctions.

    Abstract

    Low-Molecular-Weight Cyclin E Deregulates DNA Replication and Damage Repair to Promote Genomic Instability in Breast Cancer

    Mechanistically, FL-cycE overexpression inhibited the proliferation of human mammary epithelial cells by replication stress and DNA damage accumulation, but low-molecular-weight cyclin-E facilitated replication stress tolerance by upregulating DNA replication and damage repair.

    Abstract

    Size Optimization of Carfilzomib Nanocrystals for Systemic Delivery to Solid Tumors

    Both carfilzomib albumin-coated nanocrystals showed similar or higher cytotoxicity than carfilzomib commercial formulation against breast cancer cells.

    Abstract

    Sensory Nerves Enhance Triple-Negative Breast Cancer Invasion and Metastasis via the Axon Guidance Molecule PlexinB3

    Direct in vitro co-culture of human TNBC cells with the dorsal root ganglia of adult female mice revealed that TNBC cells adhered to sensory neuron fibers leading to an increase in migration speed.

    An Investigation of Sigma-1 Receptor Expression and Ligand-Induced Endoplasmic Reticulum Stress in Breast Cancer

    Treatment with a sigma-1 receptor protein (Sig1R) antagonist, 1-(4-iodophenyl)-3-(2-adamantyl)guanidine, activated the unfolded protein response in TNBC (high-Sig1R expressing) and ER + (low-Sig1R expressing) breast cancer cell lines.

    Abstract

    Chemotherapy Induces ACE2 Expression in Breast Cancer via the ROS-AKT-HIF-1α Signaling Pathway: A Potential Prognostic Marker for Breast Cancer Patients Receiving Chemotherapy

    Small interfering RNAs or lentivirus-mediated shRNA was used to silence angiotensin-converting enzyme 2 (ACE2) and HIF-1α expression in cellular models.

    Targeting HER2-Positive Breast Cancer: Advances and Future Directions

    The authors discuss the current standards of care for HER2-positive breast cancer, mechanisms of resistance to HER2-targeted therapy and new therapeutic approaches and agents, including strategies to harness the immune system.
    [Nature Reviews Drug Discovery]

    Abstract

    Endoplasmic Reticulum Stress Targeted Therapy for Breast Cancer

    Scientists summarize the function and main mechanisms of endoplasmic reticulum stress (ERS) in different molecular types of breast cancer, and focus on the development of agents targeting ERS to provide new treatment strategies for breast cancer.
