    A Nanotherapeutic Strategy to Overcome Chemotherapeutic Resistance of Cancer Stem-Like Cells

    Investigators report a nanotherapeutic strategy to kill cancer stem cells in tumors using nanoparticles that were co-loaded with the differentiation-inducing agent, all-trans retinoic acid, and the chemotherapeutic drug, camptothecin.

    Abstract

    Targeting ACSS2 with a Transition State Mimetic Inhibits Triple-Negative Breast Cancer Growth

    Researchers synthesized a small molecule inhibitor that acted as a transition state mimetic to block acetyl-CoA synthetase 2 (ACSS2) activity in vitro and in vivo.

    Abstract

    Interplay between Desmoglein2 and Hypoxia Controls Metastasis in Breast Cancer

    Investigators found that high expression of desmoglein2, a component of desmosome-mediated intercellular adhesion complexes, promoted tumor growth, increased the prevalence of circulating tumor cell clusters, and facilitated distant organ colonization.

    Abstract

    Hsa_circ_0005273 Facilitates Breast Cancer Tumorigenesis by Regulating YAP1-Hippo Signaling Pathway

    The effect of knocking down hsa_circ_0005273 in breast cancer cell lines was evaluated by examinations of cell proliferation, migration, and cell cycle.

    Prolactin Receptor-Driven Combined Luminal and Epithelial Differentiation in Breast Cancer Restricts Plasticity, Stemness, Tumorigenesis and Metastasis

    The authors found that interfering with the expression of the receptor for the lactogenic hormone prolactin in breast cancer cells representative of the luminal and epithelial breast cancer subtypes resulted in a loss of their differentiation state, enriched for stem-like cell subpopulations, and increased their tumorigenic capacity in a subtype-specific manner.

    METTL3 Promotes Adriamycin Resistance in MCF-7 Breast Cancer Cells by Accelerating Pri-microRNA-221-3p Maturation in a m6A-Dependent Manner

    Scientists identified the methyltransferase-like 3/microRNA-221-3p/homeodomain-interacting protein kinase 2/Che-1 (METTL3/miR-221-3p/HIPK2/Che-1) axis as a novel signaling event that may be responsible for the resistance of breast cancer cells to adriamycin.
