    EYA4 Promotes Breast Cancer Progression and Metastasis through Its Role in Replication Stress Avoidance

    Researchers found that the over-expression of Eyes Absent homolog 4 (EYA4) in breast tissue led to an aggressive and invasive breast cancer phenotype, while the inhibition of EYA4 reduced tumorigenic properties of breast cancer cells in vitro and in vivo.

    Stroma-Mediated Breast Cancer Cell Proliferation Indirectly Drives Chemoresistance by Accelerating Tumor Recovery between Chemotherapy Cycles

    The authors explored whether the direct reduction of therapy sensitivity induced by stroma-produced paracrine factors contributed to the link between stroma and poor responses to chemotherapies.

    Abstract

    Spatiotemporal Modeling of Chemoresistance Evolution in Breast Tumors Uncovers Dependencies on SLC38A7 and SLC46A1

    Investigators modeled the spatiotemporal changes promoting chemotherapy resistance in breast cancer. They revealed an important priming phase that rendered cancer cells previously exposed to sublethal drug concentrations refractory to dose escalation.

    UBE3B Promotes Breast Cancer Progression by Antagonizing HIF-2α Degradation

    UBE3B depletion inhibited breast cancer cell proliferation, colony formation, migration, and invasion in vitro and suppressed breast tumor growth and lung metastasis in vivo.

    Abstract

    Integrin β4 Promotes DNA Damage-Related Drug Resistance in Triple-Negative Breast Cancer via TNFAIP2/IQGAP1/RAC1

    Scientists indicated that the Integrin β4/TNFAIP2/IQGAP1/RAC1 axis provided potential therapeutic targets to overcome DNA damage-related drug resistance in TNBC.

    miRNA-214-3p Stimulates Carcinogen-Induced Mammary Epithelial Cell Apoptosis in Mammary Cancer-Resistant Species

    Researchers showed that increasing miR-214 expression and decreasing expression of its target gene nuclear factor kappa B subunit 1 in mammosphere-derived epithelial cells abolished 7,12-Dimethylbenz(a)anthracene-induced apoptosis.

    Dynamic Ultrasound Molecular-Targeted Imaging of Senescence in Evaluation of Lapatinib Resistance in HER2-Positive Breast Cancer

    Scientists established a new cellular model of reversible cellular senescence using lapatinib (LAP) and human epidermal growth factor receptor 2 positive (HER2+) breast cancer cells and found that reversible senescence contributed to LAP resistance in HER2+ breast cancer.

    Knockdown of LINC00702 Inhibits the Growth and Induces Apoptosis of Breast Cancer through the Wnt/β-Catenin Pathway

    Researchers elucidated the role of LINC00702, a long non-coding RNA, in breast cancer (BC) with bioinformatic and transcriptomic methods. Additionally, they evaluated the impact of LINC00702 knockdown on BC progression.

    IU Cancer Researcher Receives $2.2 Million Grant for Metastatic Breast Cancer Research

    A breast cancer researcher at the Indiana University (IU) Melvin and Bren Simon Comprehensive Cancer Center received a five-year, $2.2 million grant from the National Cancer Institute to examine how certain immune cells support metastatic breast cancer development—and how to stop it.
