    Spatiotemporal Control of ERK Pulse Frequency Coordinates Fate Decisions During Mammary Acinar Morphogenesis

    By imaging single-cell ERK activity dynamics in MCF10A acini, researchers found that mammary epithelial acinar morphogenesis fates depended on the average frequency of non-periodic ERK pulses.

    TGFB2-AS1 Inhibits Triple-Negative Breast Cancer Progression via Interaction With SMARCA4 and Regulating Its Targets TGFB2 and SOX2

    The authors identified the long noncoding RNA TGFB2-AS1 as an important regulator of the reversibility and plasticity of noncancer stem cell populations in TNBC.

    A Proliferative to Invasive Switch Is Mediated by srGAP1 Downregulation Through the Activation of TGF-β2 Signaling

    Scientists identified srGAP1 as a regulator of a proliferative-to-invasive switch in breast cancer cells, and high-resolution light-sheet microscopy demonstrated that these cells could switch form actin-rich protrusions during extravasation.

    Targeting of Mcl-1 in Breast Cancer-Associated Fibroblasts Reverses Their Myofibroblastic Phenotype and Pro-Invasive Properties

    Investigators showed that pharmacological inhibition or knock down of MCL-1 in primary breast ancer-associated fibroblasts directly derived from human samples mitigated myofibroblastic features.

    Blockage of Orai1-Nucleolin Interaction Meditated Calcium Influx Attenuates Breast Cancer Cells Growth

    Researchers demonstrated that Nucleolin (NCL) was a novel interacting partner of Orai1. NCL is a multifunctional nucleocytoplasmic protein and is upregulated in human breast tumors.

    MicroRNA-570 Targets the HSP Chaperone Network, Increases Proteotoxic Stress and Inhibits Mammary Tumor Cell Migration

    Investigators identified a potent microRNA, miR-570 that could bind the 3′untranslated regions of multiple heat shock protein (HSP) mRNAs and inhibit HSP synthesis.
