    AMPK Phosphorylates and Stabilizes Copper Transporter 1 to Synergize Metformin and Copper Chelator for Breast Cancer Therapy

    CRISPR/Cas9-based kinome screening was used to identify the copper transporter 1 (CTR1) upstream kinases. Immunofluorescence assays were utilized to detect CTR1 localization. In vitro kinase assays and mass spectrometry were performed to detect CTR1 phosphorylation.

    Abstract

    Chaperone-Mediated Autophagy Degrade Dicer to Promote Breast Cancer Metastasis

    Investigators showed that Dicer expression correlated with metastasis and invasion without affecting cell stability in breast cancer cells.

    Abstract

    DIF-1 Exhibits Anticancer Activity in Breast Cancer via Inhibition of CXCLs/CXCR2 Axis-Mediated Communication between Cancer-Associated Fibroblasts and Cancer Cells

    Scientists investigated the effect of differentiation-inducing factor-1 (DIF-1) on the tumor microenvironment using mouse TNBC 4T1-GFP cells, mouse macrophage RAW 264.7 cells, and mouse primary dermal fibroblasts.

    Abstract

    Acquired Radioresistance in EMT6 Mouse Mammary Carcinoma Cell Line Is Mediated by CTLA-4 and PD-1 through JAK/STAT/PI3K Pathway

    The underlying mechanism leading to the development of acquired radioresistance in the EMT6 mouse mammary carcinoma cell line and the potential pathway involved was investigated by comparing differential gene expressions between parental and acquired radioresistance cells.

    Cytotoxic and Chemomodulatory Effects of Phyllanthus niruri in MCF-7 and MCF-7ADR Breast Cancer Cells

    Investigators assessed the potential cytotoxicity of P. niruri extracts (and fractions) alone and in combination with doxorubicin against naïve, MCF-7, and doxorubicin-resistant breast cancer cell lines, MCF-7ADR.

    Bufalin Reverses ABCB1-Mediated Resistance to Docetaxel in Breast Cancer

    To determine whether bufalin (BUF) could reverse the drug resistance to docetaxel and restore efficacy in breast cancer, the reversal index of BUF was detected by cell counting kit-8 assays. The effects of BUF on enhancing the apoptosis of docetaxel were detected by flow cytometry and Western blot.

    Substrate Stiffness Regulates Focal Adhesion Kinase Alternative Splicing in Breast Cancer

    To test whether stiffness-mediated alternative splicing could regulate the expression of focal adhesion kinase (FAK) splice variants and influence tumor progression, researchers first investigated FAK mRNA splicing as a function of matrix stiffness using RNAseq.
