    Hypoxia-Inducible Factor-Dependent ADAM12 Expression Mediates Breast Cancer Invasion and Metastasis

    The authors reported that exposure of human breast cancer cells to hypoxia activated epidermal growth factor receptor (EGFR) signaling was mediated by the hypoxia-inducible factor-dependent expression of a disintegrin and metalloprotease 12 (ADAM12).

    Abstract

    FOXO3A-Induced LINC00926 Suppresses Breast Tumor Growth and Metastasis through Inhibition of PGK1-Mediated Warburg Effect

    Researchers identified a lncRNA LINC00926 negatively correlated with phosphoglycerate kinase 1 (PGK1) and predicting a good clinical outcome of breast cancer.

    ALG3 Contributes to Stemness and Radioresistance through Regulating Glycosylation of TGF-β Receptor II in Breast Cancer

    Scientists screened all ten asparagine-linked glycosylation (ALG) members in breast cancer patients’ samples by RT-PCR. Cell viability after irradiation was determined by CCK-8 assay and flow cytometry.

    A Novel Lnc408 Maintains Breast Cancer Stem Cell Stemness by Recruiting SP3 to Suppress CBY1 Transcription and Increasing Nuclear β-Catenin Levels

    The authors identified a novel lncRNA 408 (lnc408) in epithelial-mesenchymal transition-related breast cancer stem cells (BCSCs). The lnc408 was highly expressed in BCSCs in vitro and in vivo.

    Capsanthin Induces G1/S Phase Arrest, Erlotinib-Sensitivity and Inhibits Tumor Progression by Suppressing EZH2-Mediated Epigenetically Silencing of p21 in Triple-Negative Breast Cancer Cells

    Investigators tested the anti-proliferative activity of capsanthin with human TNBC and found that cell proliferation was inhibited after 24, 48, and 72 h of treatment.

    The Role of HER2 and HER3 in HER2-Amplified Cancers Beyond Breast Cancers

    The expression and signaling activity of HER2, HER3, and downstream pathway proteins were studied in cell panels representing HER2-amplified cancers of the breast, bladder, colon and rectal, stomach, esophagus, lung, tongue, and endometrium along with controls lacking HER2 amplification.
