    ERα-Associated Translocations Underlie Oncogene Amplifications in Breast Cancer

    The authors showed that focal amplifications in breast cancer frequently derived from a mechanism, which they termed translocation–bridge amplification, involving inter-chromosomal translocations that lead to dicentric chromosome bridge formation and breakage.

    A Sense-Antisense RNA Interaction Promotes Breast Cancer Metastasis via Regulation of NQO1 Expression

    Researchers identified one antisense RNA that drove cancer progression by upregulating the redox enzyme NADPH quinone dehydrogenase 1 (NQO1), and named it NQO1-AS.

    p140Cap Inhibits β-Catenin in the Breast Cancer Stem Cell Compartment Instructing a Protective Anti-Tumor Immune Response

    Integrative transcriptomic and preclinical studies unraveled that p140Cap controlled an epistatic axis where, through the upstream inhibition of β-Catenin, it restricted tumorigenicity and self-renewal of tumor-initiating cells.

    Inhibition of ACAA1 Restrains Proliferation and Potentiates the Response to CDK4/6 Inhibitors in Triple-Negative Breast Cancer

    Researchers identified that acetyl-CoA acyltransferase 1 (ACAA1) was highly expressed in the luminal androgen receptor subtype of TNBC compared with adjacent normal tissues in their TNBC proteomics dataset.

    Abstract

    A Dual-Action Niclosamide-Based Prodrug That Targets Cancer Stem Cells and Inhibits TNBC Metastasis

    Investigators reported a prodrug, Nic-A that was designed to target TNBC cancer stem cells (CSCs) and was found to inhibit both proliferating TNBC cells and CSCs via signal transducer and transcriptional activator 3 dysregulation and suppression of CSC-like properties.

    Benzimidazole Carbamate Induces Cytotoxicity in Breast Cancer Cells via Two Distinct Cell Death Mechanisms

    Scientists comprehensively evaluated the cellular effects of N-(6-benzoyl-1H-benzimidazol-2-yl)carbamate in a panel of human breast cancer cell lines and normal breast cells.

    CHMP4A Stimulates CD8+ T-Lymphocyte Infiltration and Inhibits Breast Tumor Growth via the LSD1/IFNβ Axis

    Using bioinformatics analysis, the authors identified four hub prognostic genes related to CD8+ T-lymphocyte infiltration and found that chromatin-modifying protein 4A (CHMP4A) was the most significant gene.

    Potential Effect of Chloroquine and Propranolol Combination to Treat Colorectal and Triple-Negative Breast Cancers

    Researchers evaluated the effect of the combination of chloroquine and propranolol on colorectal cancer and TNBC by using as in vitro models the colorectal cancer cell lines HCT116, HT29, and CT26, and as TNBC models the 4T1, M-406, and MDA-MB-231 cell lines.

    Functional Impact of Non-Coding RNAs in High-Grade Breast Carcinoma: Moving from Resistance to Clinical Applications: A Comprehensive Review

    The authors present a systematic overview of biogenesis and down streaming molecular mechanism of the subgroups of non-coding RNAs (ncRNAs). They also explain ncRNA-based strategies and challenges to target the chemo-, radio-, and immunoresistance in TNBCs from a clinical standpoint.
