Platelet-Derived ​SDF-1 Primes the Pulmonary Capillary Vascular Niche to Drive Lung Alveolar Regeneration
Researchers found that platelets trigger lung regeneration by supplying ​stromal-cell-derived factor-1 (​SDF-1). After PNX, activated platelets stimulate ​SDF-1 receptors ​CXCR4 and ​CXCR7 on pulmonary capillary endothelial cells to deploy the angiocrine membrane-type metalloproteinase ​MMP14, stimulating alveolar epithelial cell expansion and neo-alveolarization. [Nat Cell Biol] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
In Vitro Reconstruction of Branched Tubular Structures from Lung Epithelial Cells in High Cell Concentration Gradient Environment
Scientists have succeeded in developing hollow branching structure in vitro commonly observed in lung airway using primary lung airway epithelial cells. [Sci Rep] Full Article

Maternal Vitamin D and E Intakes during Early Pregnancy Are Associated with Airway Epithelial Cell Responses in Neonates
Researchers tested the hypothesis that maternal vitamin D and E status in early pregnancy is associated with airway epithelial cell (AEC) responses in new born infants and examined constitutive and TNFα/IL-1β, house dust mite extract or lipopolysaccharide stimulated neonatal AEC responses in vitro. [Clin Exp Allergy] Abstract

Cytotoxicity, Oxidative Stress and Genotoxicity Induced by Glass Fibers on Human Alveolar Epithelial Cell Line A549
Scientists aimed to verify the cytotoxic and genotoxic effects and oxidative stress production induced by in vitro exposure of human alveolar epithelial cells A549 to glass fibers. [Toxicol In Vitro] Abstract

A Pharmacometric Pulmonary Model Predicting the Extent and Rate of Distribution from Plasma to Epithelial Lining Fluid and Alveolar Cells – Using Rifampicin as an Example
Researchers developed a drug-unspecific approach to pharmacometric modeling for predicting the rate and extent of distribution from plasma to epithelial lining fluid and alveolar cells for data emanating from studies involving bronchoalveolar lavage sampling, using rifampicin as an example.

β-Arrestin-1 Mediates Nicotine-Induced Metastasis through E2F1 Target Genes that Modulate Epithelial-Mesenchymal Transition
Stimulation of multiple non-small cell lung cancer (NSCLC) cell lines with nicotine led to enhanced recruitment of β-arrestin-1 and E2F1 on vimentin, fibronectin, ZEB1 and ZEB2 promoters. Further, there was significantly more β-arrestin-1 and E2F1 associated with these promoters in human NSCLC tumors and β-arrestin-1 levels correlated with vimentin and fibronectin levels in human NSCLC samples.

Phosphorylation of FADD by the Kinase CK1α Promotes KRASG12D-Induced Lung Cancer
Using immunohistochemistry analysis and in vivo imaging of conditional mouse models of KRASG12D-driven lung cancer, scientists found that the deletion of the gene encoding Fas-associated death domain (FADD) suppressed tumor growth, reduced the proliferative index of cells, and decreased the activation of downstream effectors of the RAS-MAPK pathway that promote the cell cycle, including retinoblastoma and cyclin D1. [Sci Signal] Abstract

Receptor Tyrosine Kinase EphA5 Is a Functional Molecular Target in Human Lung Cancer
Researchers show that the receptor tyrosine kinase EphA5 is specifically overexpressed in lung cancer, and is involved in regulating cellular responses to genotoxic insult. In the absence of EphA5, lung cancer cells displayed a defective G1/S cell cycle checkpoint, were unable to resolve DNA damage, and became radiosensitive. [J Biol Chem] Abstract | Full Article

WT1 Enhances Proliferation and Impedes Apoptosis in KRAS Mutant NSCLC via Targeting cMyc
Scientists investigated the role of WT1 and KRAS in proliferation and apoptosis. The potential mechanisms that WT1 promotes proliferation and impedes apoptosis through affecting multiple apoptosis-related regulators in KRAS mutant non-small cell lung cancer (NSCLC) cells were identified. [Cell Physiol Biochem] Abstract

Epigenetic Inactivation of SOX1 Promotes Cell Migration in Lung Cancer
Researchers investigated whether the promoter hypermethylation of SOX1 is involved in human lung carcinogenesis. They demonstrate that restoration of SOX1 inhibited cell migration by regulating actin cytoskeletal remodeling. [Tumor Biol] Abstract

Significantly Inhibitory Effects of Low Molecular Weight Heparin (Fraxiparine) on the Motility of Lung Cancer Cells and Its Related Mechanism
Scientists found that Fraxiparine significantly inhibited the invasive, migratory, and adhesive characteristics of A549 and 95D cells after 24 hours incubation in a dose-dependent manner. [Tumor Biol] Abstract

Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors in Early-Stage Non-Small Cell Lung Cancer
Preliminary findings suggest that epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors may also be beneficial as adjuvant therapy following complete resection in patients with EGFR-mutation-positive early-stage I-III non-small cell lung cancer; however, many questions remain unanswered.

UAB Wins Grant to Study Effects of Fungi on Asthma
Researchers from the University of Alabama at Birmingham have received a $1.75 million, four-year grant from the National Heart, Lung and Blood Institute, one of the National Institutes of Health, to better understand how a fungal reaction affects asthma and to search for ways to interfere in that process and reduce the severity of fungal asthma. [University of Alabama at Birmingham] Press Release

Trudeau Institute Researcher Receives NIH Funding
The Trudeau Institute has been awarded $536,000 over a two-year period from the National Institute of Allergy and Infectious Diseases. The grant will support a research project of Alexei Tumanov, M.D., Ph.D., “Defining the role of lymphotoxin signaling in viral-induced lung immunopathology.” [Trudeau Institute] Press Release

New Animal Models Faithfully Reproduce the Tumor of Each Patient
A team from the Catalan Institute of Oncology and Bellvitge Biomedical Research Institute has developed new animal models that reproduce faithfully the evolution and malignancy of different human tumors. [Bellvitge Biomedical Research Institute] Press Release
