    Lung Adenocarcinoma Promotion by Air Pollutants

    Researchers proposed that environmental particulate matter measuring ≤2.5 μm, known to be associated with lung cancer risk, promoted lung cancer by acting on cells that harbor pre-existing oncogenic mutations in healthy lung tissue.

    Chronic Exposure to Secondary Organic Aerosols Causes Lung Tissue Damage

    Scientists showed that chronic exposure of mice to secondary organic aerosols resulted in lung inflammation and tissue destruction. They also indicated increased matrix metalloproteinase proteolytic activity suggesting its contribution to lung tissue inflammation and degradation.

    Activation of Nrf2 Signaling Pathway by Tectoridin Protects against Ferroptosis in Particulate Matter-Induced Lung Injury

    Researchers investigated the protective role of the Nrf2 signaling pathway and its bioactive molecule tectoridin in PM2.5-induced lung injury by regulating ferroptosis.

    Abstract

    Enhanced Lyn Activity Causes Severe, Progressive Emphysema and Lung Cancer

    Investigators presented a novel, pre-clinical model where an activating mutation in Lyn, a non-receptor Src family kinase expressed in immune cells, epithelium, and endothelium, all strongly implicated in the pathogenesis of COPD.

    Abstract

    Transport of Designed Ankyrin Repeat Proteins through Reconstituted Human Bronchial Epithelia and Protection against SARS-CoV-2

    Transepithelial migration through air–liquid interface cultures of reconstituted human bronchial epithelia was assessed by enzyme-linked immunosorbent assays and confocal laser scanning microscopy for different designed ankyrin repeat protein designs in comparison to a monoclonal antibody.

    Abstract

    LncRNA LITATS1 Suppresses TGF-β-Induced EMT and Cancer Cell Plasticity by Potentiating TβRI Degradation

    Scientists reported that the long noncoding RNA LITATS1 was an epithelial gatekeeper in normal epithelial cells and inhibited epithelial-mesenchymal transition in breast and NSCLC cells. Transcriptome analysis identified LITATS1 as a TGF-β target gene.

    MiR-122-5p Regulates the Mevalonate Pathway by Targeting p53 in Non-Small Cell Lung Cancer

    Investigators evaluated the role of these factors in NSCLC. The role of miR-122-5p and p53 was established in samples from NSCLC patients, and human NSCLC cells A549 using the miR-122-5p inhibitor, miR-122-5p mimic, and si-p53.

    Mechanism of lnRNA-ICL Involved in Lung Cancer Development in COPD Patients through Modulating microRNA-19-3p/NKRF/NF-κB Axis

    Scientists reported for the first time that a key long non-coding RNA-ICL was involved in the regulation of NF-κB activity in lung cancer tissues of COPD patients.
