    PHF14 Enhances DNA Methylation of SMAD7 Gene to Promote TGF-β-Driven Lung Adenocarcinoma Metastasis

    Researchers found that SMAD7, a direct downstream transcriptional target and also a key antagonist of TGF-β signaling, was transcriptionally suppressed in lung adenocarcinoma due to DNA hypermethylation.

    Wnt3a-Loaded Extracellular Vesicles Promote Alveolar Epithelial Regeneration after Lung Injury

    Scientists devised a strategy to deliver the membrane-bound wingless-type MMTV integration site family, member 3A (Wnt3a) over a long distance by anchoring it to the surface of extracellular vesicles.

    EPC-Exosomal miR-26a-5p Improves Airway Remodeling in COPD by Inhibiting Ferroptosis of Bronchial Epithelial Cells via PTGS2/PGE2 Signaling Pathway

    Researchers explored whether exosomes and prostaglandin-endoperoxide synthase 2 (PTGS2)/PGE2 signaling pathway affected COPD by influencing the ferroptosis of bronchial epithelial cells by constructing a model of COPD.

    Abstract

    Post-Radiation Treatment of 3,3′-Diselenodipropionic Acid Augments Cell Kill by Modulating DNA Repair and Cell Migration Pathways in A549 Cells

    Scientists tested whether ionizing radiation treatment along with 3,3′-diselenodipropionic acid, a redox-active organodiselenide achieved better tumor control by suppressing the growth and migration of lung cancer cells.

    Downregulation of circ_PLXND1 Inhibits Tumorigenesis of Non-Small Cell Lung Carcinoma via miR-1287-5p/ERBB3 Axis

    Investigators explored the role and underlying mechanism of circ_PLXND1 in NSCLC progression. Circ_PLXND1 and ERBB3 were upregulated while miR-1287-5p was downregulated in NSCLC tissues and cells.
