    MINDY1 Promotes Breast Cancer Cell Proliferation by Stabilizing Estrogen Receptor α

    Scientists identified MINDY1, a member that belongs to the motif interacting with Ubcontaining novel DUB family (MINDY), as a potential deubiquitylase of estrogen receptor α in breast cancer.

    Loss of TRIM31 Promotes Breast Cancer Progression through Regulating K48- and K63-Linked Ubiquitination of p53

    The authors showed that TRIM31 was downregulated in breast cancer tissues and negatively correlated with breast cancer progression. Both gain- and loss-of-function assays indicated that TRIM31 inhibited the proliferation, colony formation, migration, and invasion of breast cancer cells.

    Germline RAD51B Variants Confer Susceptibility to Breast and Ovarian Cancers Deficient in Homologous Recombination

    Investigators demonstrated that tumors harboring biallelic RAD51B alteration were deficient in homologous recombination DNA repair deficiency, as evidenced by analysis of sequencing data and in vitro functional assays.

    A Novel Brain-Permeant Chemotherapeutic Agent for the Treatment of Brain Metastasis in Triple-Negative Breast Cancer

    Scientists investigated the activity of QBS10072S in vitro with various cell lines including the human TNBC cell line MDA-MB-231 and its brain-tropic derivative MDA-MB-231-BR3, where QBS10072S was found to be preferentially toxic to TNBC cells.

    Fluid Flow Exposure Promotes Epithelial-to-Mesenchymal Transition and Adhesion of Breast Cancer Cells to Endothelial Cells

    Researchers showed that fluid forces on the order of 1 Pa promoted epithelial-to-mesenchymal transition and adhesion of breast cancer cells to an endothelial monolayer and identified biomarkers were distinctly expressed in patient populations.

    The Long Non-Coding RNA ET-20 Mediates EMT by Impairing Desmosomes in Breast Cancer Cells

    Researchers reported the identification of 114 novel long non-coding RNAs that changed their expression during TGFβ-induced epithelial-mesenchymal transition in murine breast cancer cells.

    DRAIC Promotes Growth of Breast Cancer by Sponging miR-432-5p to Upregulate SLBP

    Investigators conducted a qRT-PCR assay to measure the expression of downregulated RNA in cancer (DRAIC) and other downstream target genes. They uncovered that DRAIC was expressed at a high level in breast cancer cells.

    FAM49B Promotes Breast Cancer Proliferation, Metastasis, and Chemoresistance by Stabilizing ELAVL1 Protein and Regulating Downstream Rab10/TLR4 Pathway

    The authors systematically studied the role of FAM49B in the proliferation, metastasis, apoptosis, and chemoresistance of breast cancer, as well as the corresponding molecular mechanisms and downstream target.

    Downregulation of the FBXO43 Gene Inhibits Tumor Growth in Human Breast Cancer by Limiting Its Interaction with PCNA

    Researchers evaluated FBXO43 expression in breast cancer (BC) and analyzed The Cancer Genome Atlas. RT-qPCR and western blotting were utilized to detect FBXO43 expression in BC cell lines.

    Sauchinone Inhibits the Proliferation, Migration and Invasion of Breast Cancer Cells by Suppressing Akt-CREB-MMP13 Signaling Pathway

    Scientists investigated the effects of sauchinone on the growth of breast cancer cells along with the underlying molecular mechanisms. Results showed that sauchinone treatment markedly inhibited the proliferation, migration, and invasion of breast cancer cells.
