    SF3A2 Promotes Progression and Cisplatin Resistance in Triple-Negative Breast Cancer via Alternative Splicing of MKRN1

    Splicing factor 3a subunit 2 (SF3A2), a poorly defined splicing factor, was notably elevated in TNBC tissues and promoted TNBC progression, as confirmed by cell proliferation, colony formation, transwell migration, and invasion assays.

    Abstract

    Establishing Conditions for the Generation and Maintenance of Estrogen Receptor-Positive Organoid Models of Breast Cancer

    Investigators reported the development of an estrogen receptor-positive (ER+) breast tumor organoid medium that conserved ER expression, estrogen responsiveness, and dependence, as well as sensitivity to endocrine therapy of ER+ patient-derived xenograft organoids.

    UTRN as a Potential Biomarker in Breast Cancer: A Comprehensive Bioinformatics and In Vitro Study

    The authors conducted a thorough examination of utrophin (UTRN) using both bioinformatic and in vitro experiments. UTRN expression decreased in breast cancer compared to standard samples, and high UTRN expression correlated with better prognosis.

    Activation of the YY1-UGT2B7 Axis Promotes Mammary Estrogen Homeostasis Dysregulation and Exacerbates Breast Tumor Metastasis

    Scientists demonstrated that up-regulation of YY1 expression was closely associated with breast cancer metastasis, and that high YY1 expression could promote the migratory invasive ability of breast cancer cells.
