Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas. Therefore, epigenomics may represent a novel and promising tool for precision medicine, and in particular, the detection of epigenomic biomarkers in liquid biopsies will be of great interest for monitoring diseases in patients...

Small cell lung cancer (SCLC) is a devastating and aggressive neuroendocrine carcinoma of the lung. It accounts for ~15% of lung cancer mortality and has had no improvement in standard treatment options for nearly 30 years. However, there is now hope for change with new therapies and modalities of therapy. Immunotherapies and checkpoint inhibitors are entering clinical practice, selected targeted therapies show promise, and "smart bomb"-based drug/radioconjugates have led to good response in early clinical trials...

Budesonide (BUD), a poorly soluble anti-inflammatory drug, is used to treat patients suffering from asthma and COPD (Chronic Obstructive Pulmonary Disease). Hydroxypropyl-β-cyclodextrin (HPβCD), a biocompatible cyclodextrin known to interact with cholesterol, is used as a drug-solubilizing agent in pharmaceutical formulations. Budesonide administered as an inclusion complex within HPβCD (BUD:HPβCD) required a quarter of the nominal dose of the suspension formulation and significantly reduced neutrophil induced inflammation in a COPD mouse model exceeding the effect of each molecule administered individually...

Measurement of exhaled carbon monoxide (eCO) might help in the selection of lung grafts during ex vivo lung perfusion since its endogenous production is increased under ischemia reperfusion. The objective of this study was to measure eCO variations depending on the extent of lung ischemia reperfusion injuries. Using a porcine model and a laser spectrometer instrument, eCO was measured during ex vivo lung perfusion. eCO was compared after 30 min (D0) or 24 h (D1) of cold ischemia. The ability of eCO to distinguish lungs deemed suitable for transplantation was evaluated...

Tight and adherens junctions play critical roles in the barrier, adhesion, and signaling functions of epithelial and endothelial cells. How the molecular organization of these junctions is tuned to the widely diverse physiological requirements of each tissue type is not well understood. Here, we address this question by examining the expression, localization, and interactions of major cytoplasmic plaque proteins of tight and adherens junctions in different cultured epithelial and endothelial cell lines. Immunoblotting and immunofluorescence analyses show that the expression profiles of cingulin, paracingulin, ZO-1, ZO-2, ZO-3, PLEKHA7, afadin, PDZD11, p120-catenin, and α-catenin, as well as the transmembrane junctional proteins occludin, E-cadherin, and VE-cadherin, are significantly diverse when comparing kidney cells (MDCK, mCCD), keratinocytes (HaCaT), lung carcinoma (A427, A549), and endothelium-derived cells (bEnd...

BACKGROUND: Although most people associate smoking with lung cancer and heart disease, few are aware of the impact of smoking on ocular health. Studies have suggested a better knowledge of this association might promote higher quit rates, particularly in teenagers. The purpose of our study was to determine the knowledge of teenagers about the effects of smoking on ocular health and the fear associated with several tobacco-related health conditions. METHODS: A self-administered questionnaire was distributed to 180 high school students aged 14 to 17 years...

Squamous cell lung cancers (SQCLC) account for 25% of all NSCLCs, yet the prognosis of these patients is poor and treatment options are limited. Amplified FGFR1 is one of the most common oncogenic events in SQCLCs, occurring in ~20% of cases. AZD4547 is a potent and selective FGFR1-3 inhibitor with anti-tumor activity in FGFR1 amplified SQCLC cell lines and patient-derived xenografts. <br /><br />Experimental Design: Based on these data, we performed a phase 1 study of AZD4547 in patients with previously treated stage IV FGFR1 amplified SQCLCs (NCT00979134)...
