    Sohlh2 Promotes Pulmonary Fibrosis via Repression of p62/Keap1/Nrf2 Mediated Anti-Oxidative Signaling Pathway

    Using a type II alveolar epithelial cell-specific Sohlh2 conditional knock-in mouse model, researchers found that Sohlh2, a basic HLH transcription factor, accelerated age-related pulmonary fibrosis.

    Cellular Senescence Contributes to the Progression of Hyperoxic Bronchopulmonary Dysplasia

    Cellular senescence increased in rat and human bronchopulmonary dysplasia lungs, as evidenced by increased oxidative DNA damage, tumor suppressors, GL-13 stain, and inflammatory cytokines with decreased cell proliferation and lamin B expression.

    Agonists and Hydrogen Peroxide Mediate Hyperoxidation of β2-Adrenergic Receptor in Airway Epithelial Cells: Implications for Tachyphylaxis to β2-Agonists in Constrictive Airway Disorders

    Using airway epithelial cell lines and primary small airway epithelial cells from healthy and asthma-diseased donors, investigators showed that β2AR agonism generated H2O2 in a receptor and NAPDH oxidase-dependent manner.

    ZC3H4 Governs Epithelial Cell Migration through ROCK/P-PYK2/P-MLC2 Pathway in Silica-Induced Pulmonary Fibrosis

    Scientists explored the mechanisms of ZC3H4 by which to stimulate epithelial cell migration. Pathological analysis and 2D migration assay were established to uncover the pulmonary fibrotic lesions and epithelial cell migration, respectively.

    Mesenchymal Stem Cells Ameliorate H9N2-Induced Acute Lung Injury by Inhibiting Caspase-3-GSDME-Mediated Pyroptosis of Lung Alveolar Epithelial Cells

    Researchers demonstrated that bone marrow-derived mesenchymal stem cells prevented and ameliorated acute lung injury by inhibiting Caspase-3-GSDME-mediated pyroptosis of lung epithelial cells as well as hypercytokinemia.

    IL-18 Serves as a Main Effector of CAF-Derived METTL3 Against Immunosuppression of NSCLC via Driving NF-κB Pathway

    Researchers explored whether methyltransferase like 3 (METTL3) in cancer associated fibroblasts (CAFs) affected the secretion of IL-18, which drove NSCLC cells to regulate PD-L1-mediated immunosuppression via the nuclear factor kappa B (NF-κB) pathway.

    UPK1B Promoted the Invasion and Stem Cell Characteristics of Non-Small Cell Lung Cancer Cells by Modulating C-myc/Sox4 Axis

    Uroplakin1B (UPK1B) was overexpressed or knocked down in the NSCLCs were. The proliferation and invasion of those cells were detected with the EdU staining and transwell assays.
