    Polycomb Deficiency Drives a FOXP2-High Aggressive State Targetable by Epigenetic Inhibitors

    Using a genetic model to delete Ezh2 in KRAS-driven lung adenocarcinomas, investigators observed that Ezh2 haploinsufficient tumors were less lethal and lower grade than Ezh2 fully-insufficient tumors, which were poorly differentiated and metastatic.

    GATA6 Triggers Fibroblast Activation and Tracheal Fibrosis through the Wnt/β-Catenin Pathway

    Researchers investigated the potential role of GATA6 as a novel regulator of tracheal fibrosis. It was found that GATA6 and α-smooth muscle actin were obviously increased in tracheal fibrotic granulations and in TGFβ1-treated primary tracheal fibroblasts.

    Abstract

    Involvement of JNK Signaling in Aspergillus fumigatus-Induced Inflammatory Factors Release in Bronchial Epithelial Cells

    Scientists demonstrated that the release of IL-27, MCP-1, and TNF-α from BEAS-2B cells was upregulated upon stimulation by conidia, while the mitogen-activated protein kinase signaling pathway was activated.

    ATM Inhibitor KU60019 Synergistically Sensitizes Lung Cancer Cells to Topoisomerase II Poisons by Multiple Mechanisms

    Researchers found that KU60019, a novel, and highly specific ATM kinase inhibitor interfered with the association of ATM with type II topoisomerases (TOP2) β and stabilized TOP2β-DNA cleavage complex, thereby impairing the repair of double-strand breaks, leading to accelerated cell death.
