Nanoparticles that Deliver Triplex-Forming Peptide Nucleic Acid Molecules Correct F508del CFTR in Airway Epithelium
The authors used triplex-forming peptide nucleic acids and donor DNA in biodegradable polymer nanoparticles to correct F508del. They confirmed modification with sequencing and a functional chloride efflux assay. In vitro correction of chloride efflux occurs in up to 25% of human cells. [Nat Commun] Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
CARM1 Regulates Alveolar Epithelial Senescence and Elastase-Induced Emphysema Susceptibility
Researchers investigated the contribution of coactivator-associated arginine methyltransferase-1 (CARM1) to alveolar rarefication using the mouse model of elastase-induced emphysema in vivo and siRNA-mediated knockdown in alveolar epithelial type-II-like LA4 cells in vitro. [Am J Respir Cell Mol Biol] Abstract

Deleterious Impact of Hyperglycemia on Cystic Fibrosis Airway Ion Transport and Epithelial Repair
Scientists evaluated the impact of hyperglycemia on airway epithelial repair and transepithelial ion transport, which are critical in maintaining lung integrity and function. Non-cystic fibrosis (CF) and CF airway epithelial cells were exposed to low or high glucose before ion current and wound repair rate measurements. [J Cyst Fibros] Abstract

Glucocorticoids Distinctively Modulate the CFTR Channel with Possible Implications in Lung Development and Transition into Extrauterine Life
Researchers analyzed the influence of glucocorticoids on pulmonary Cl channels. Alveolar cells from fetal and adult rats, A549 cells, bronchial Calu-3 and 16HBE14o- cells, and primary rat airway cells were studied with real-time quantitative PCR and Ussing chambers. [PLoS One] Full Article

Effect of Elevated Carbon Dioxide on Bronchial Epithelial Innate Immune Receptor Response to Organic Dust from Swine Confinement Barns
Innate immune responses to Pam3CSK4, LPS and a complex innate immune stimulus, an extract from the organic dust of swine confinement barns, were tested in a human bronchial epithelial cell line, BEAS-2B. [Int Immunopharmacol] Abstract


FLLL12 Induces Apoptosis in Lung Cancer Cells through a p53/p73-Independent but Death Receptor 5-Dependent Pathway
Scientists investigated the mechanism of anti-tumor effect of FLLL12 in lung cancers. IC50 values measured by sulforhodamine B assay at 72 hours and apoptosis assays suggest that FLLL12 is 5-10–fold more potent than curcumin against a panel of premalignant and malignant lung cancer cell lines, depending on the cell line. [Cancer Lett] Abstract

PNAS-4, an Early DNA Damage Response Gene, Induces S Phase Arrest and Apoptosis by Activating Checkpoint Kinases in Lung Cancer Cells
Scientists found that PNAS-4 expression in lung tumor tissues is significantly lower than that in adjacent lung tissues and its expression is significantly increased in A549 cells after exposure to cisplatin, methyl methane sulfonate and mitomycin, and that its overexpression induces S-phase arrest and apoptosis in lung cancer cells, leading to proliferation inhibition irrespective of their p53 status. [J Biol Chem] Abstract | Full Article

miR-205 and miR-218 Expression Is Associated with Carboplatin Chemoresistance and Regulation of Apoptosis via Mcl-1 and Survivin in Lung Cancer Cells
The authors investigated the role of two distinct miR members, the miR-205 and the tumor suppressor miR-218 in the proliferation, invasion and induction of apoptosis in lung cancer cells after carboplatin treatment. [Cell Signal] Abstract

High EMT Signature Score of Invasive Non-Small Cell Lung Cancer (NSCLC) Cells Correlates with NFκB Driven Colony-Stimulating Factor 2 (CSF2/GM-CSF) Secretion by Neighboring Stromal Fibroblasts
Researchers established co-cultures of invasive or non-invasive NSCLC cell lines and various types of fibroblasts to more precisely characterize the molecular mechanism of tumor-stroma crosstalk in lung cancer. [PLoS One] Full Article

Implication of Interleukin (IL)-18 in the Pathogenesis of Chronic Obstructive Pulmonary Disease (COPD)
Published data prompt the hypothesis that IL-18 induces a broad spectrum of COPD-like inflammatory and remodeling responses in the murine lung and also induces mixed type 1, type 2, and type 17 cytokine responses. The majority of studies identify IL-18 as a potential target for future COPD therapeutics to limit both the destructive and remodeling processes occurring in COPD lungs. [Cytokine] Abstract

UAB Secures $11 Million DOD Grant for COPD Study
Researchers at the University of Alabama at Birmingham (UAB) will lead a multisite study of the role of beta blockers in patients with chronic obstructive pulmonary disease, or COPD. The study is funded by an $11 million grant from the United States Department of Defense (DOD). [University of Alabama at Birmingham] Press Release
