    Bioscaffold Stiffness Mediates Aerosolized Nanoparticle Uptake in Lung Epithelial Cells

    The human lung A549 cells cultured on both stiff and soft polyurethane soft dendritic colloids membranes were found to be viable, capable of supporting the air–liquid interface cell culture, and maintained barrier integrity.

    LncRNA NEAT1 Aggravates Lipopolysaccharide-Induced Acute Lung Injury by Regulating the miR-98-5p/TLR4 Axis

    Mouse and cell ALI models were constructed by lipopolysaccharide (LPS). NEAT1 knockdown efficiently attenuated LPS-induced ALI and reduced LPS-induced elevation of cytokines both in vitro and in vivo

    NKX2-1 Controls Lung Cancer Progression by Inducing DUSP6 to Dampen ERK Activity

    In human tissue samples and cell lines, xenografts, and genetic mouse models, NKX2-1 induced the ERK phosphatase DUSP6, which inactivated ERK.

    Abstract

    Akt-Mediated Ephexin1–Ras Interaction Promotes Oncogenic Ras Signaling and Colorectal and Lung Cancer Cell Proliferation

    Ephexin1 was reported to be highly upregulated by oncogenic Ras, but the functional consequences of this remain poorly understood. The authors showed that Ephexin1 was highly expressed in colorectal cancer and lung cancer patient tissues.

    The E3 Ligase MIB1 Promotes Proteasomal Degradation of NRF2 and Sensitizes Lung Cancer Cells to Ferroptosis

    Researchers analyzed MIB1 expression levels in tumor samples and performed gain- and loss-of-function studies in cell lines to investigate potential roles of MIB1 in epithelial-to-mesenchymal transition, cell migration and cell survival.

    DLX6-AS1 Activated by H3K4me1 Enhanced Secondary Cisplatin Resistance of Lung Squamous Cell Carcinoma through Modulating miR-181a-5p/miR-382-5p/CELF1 Axis

    Secondary cisplatin resistance majorly undermines the cisplatin efficacy leading to a worse prognosis. Scientists identified the role of the DLX6-AS1/miR-181a-5p/miR-382-5p/CELF1 axis in regulating cisplatin resistance of lung squamous cell carcinoma.

    Histone Deacetylase 6-Mediated Downregulation of TMEM100 Expedites the Development and Progression of Non-Small Cell Lung Cancer

    Researchers elucidated the role of histone deacetylase 6 in regulating epithelial-mesenchymal transition-mediated metastasis via mRNA in NSCLC.

    Hypoxia and Proton Microbeam: Role of Gap Junction Intercellular Communication in Inducing Bystander Responses on Human Lung Cancer Cells and Normal Cells

    Confluent A549 cancer and WI-38 normal cells were subjected to condition of hypoxia or normoxia, before exposure to high-LET protons microbeam. After six hours incubation, cells were harvested and assayed for colony formation, micronucleus formation, chromosome aberration and western blotting.

    Ultrastructural Changes Associated to the Neuroendocrine Transdifferentiation of the Lung Adenocarcinoma Cell Line A549

    Investigators identified the morphological characteristics of the neuroendocrine phenotype in a human lung cancer cell line, induced by two cAMP elevating agents.

    A Role for Club Cells in Smoking-Associated Lung Adenocarcinoma

    The authors review the relevant literature in this rapidly expanding field, including results from mouse models and human studies. In addition, they present a case for club cells as cells of origin of lung adenocarcinomas that arise in smokers.
