    Alveolar Cell Fate Selection and Lifelong Maintenance of AT2 Cells by FGF Signaling

    Researchers demonstrated that alveolar cell fate specification was dictated by a classic growth factor signal, the same FGF signaling pathway that controlled the earlier steps of airway budding and branching and also initiated subsequent budding.

    Mitophagy Bridges DNA Sensing with Metabolic Adaption To Expand Lung Cancer Stem-Like Cells

    The authors identified hypermitophagy as a feature of human lung cancer stem-like cells (CSCs), promoting metabolic adaption via the Notch1-AMPK axis to drive CSC expansion.

    MET Kinase Inhibitor Reverses Resistance to Entrectinib Induced by Hepatocyte Growth Factor in Tumors with NTRK1 or ROS1 Rearrangements

    Researchers investigated whether growth factors produced by the microenvironment affected the sensitivity of NTRK1-rearranged colon cancer KM12SM cells and ROS1-rearranged NSCLC HCC78 cells to entrectinib both in vitro and in vivo.

    Anwuligan Inhibits the Progression of Non-small Cell Lung Cancer via Let-7c-3p/PI3K/AKT/mTOR Axis

    Scientists found that anwuligan inhibited the growth and metastasis of NSCLC cells in vivo and in vitro by upregulating the expression of let-7c-3p, which could regulate the PI3K/AKT/mTOR signaling pathway.
