    Organoids Model Transcriptional Hallmarks of Oncogenic KRAS Activation in Lung Epithelial Progenitor Cells

    Scientists developed organoid systems from primary mouse and human induced pluripotent stem cell-derived lung epithelial cells to model early-stage lung adenocarcinoma.

    In Vivo Antiviral Host Transcriptional Response to SARS-CoV-2 by Viral Load, Sex, and Age

    Researchers examined host response gene expression across infection status, viral load, age, and sex among shotgun RNA sequencing profiles of nasopharyngeal swabs from 430 individuals with PCR-confirmed SARS-CoV-2 and 54 negative controls.

    MUC4 Is Overexpressed in Idiopathic Pulmonary Fibrosis and Collaborates with Transforming Growth Factor β Inducing Fibrotic Responses

    The authors demonstrated that MUC4 was overexpressed in idiopathic pulmonary fibrosis patients compared with healthy subjects and located in pulmonary arteries, bronchial epithelial cells, fibroblasts, and hyperplastic alveolar type II cells.

    Abstract

    Extracellular Vesicle-Cargo miR-185-5p Reflects Type II Alveolar Cell Death after Oxidative Stress

    Scientists found that hyperoxia and its derivative, reactive oxygen species, upregulated miR-185-5p, but not miR-185-3p, in alveolar cells.

    MCL-1 Gains Occur with High Frequency in Lung Adenocarcinoma and Can Be Targeted Therapeutically

    The authors explored the role of pro-survival genes in cancer cell integrity during clonal evolution in non-small cell lung cancer.

    Epithelial to Mesenchymal Transition Is a Cause of Both Intrinsic and Acquired Resistance to KRAS G12C Inhibitor in KRAS G12C Mutant Non-Small Cell Lung Cancer

    To identify potential resistance mechanisms, investigators defined the sensitivity of a panel of KRAS G12C mutant lung cancer cell lines to a KRAS G12C inhibitor, AMG510.

    Abstract

    The Actin Modulator hMENA Regulates GAS6‐AXL Axis and Pro‐Tumor Cancer/Stromal Cell Cooperation

    Researchers report a novel function of hMENA/hMENAΔv6 isoforms in tumor‐promoting cancer‐associated fibroblasts (CAFs) and in the modulation of pro‐tumoral cancer cell/CAF crosstalk via GAS6/AXL axis regulation.

    UBE2O Targets Mxi1 for Ubiquitination and Degradation to Promote Lung Cancer Progression and Radioresistance

    Scientists showed that genetical or pharmacological blockade of UBE2O impaired tumor progression and radioresistance in lung cancer in vitro and in vivo, and these effects could be restored by Mxi1 inhibition.

    Characterization of a Novel HDAC/RXR/HtrA1 Signaling Axis as a Novel Target to Overcome Cisplatin Resistance in Human Non-Small Cell Lung Cancer

    HtrA1, a cisplatin resistance-related gene, was synergistically regulated by HDAC and RXR in NSCLC. Targeting the HDAC/RXR/HtrA1 signaling axis could rescue HtrA1 expression and reverse cisplatin resistance in NSCLC.
