The lung is directly exposed to a wide variety of inhaled toxicants and carcinogens. In order to improve our knowledge of the cellular processing of these compounds in the respiratory tract, we investigated the mRNA expression level of 380 genes encoding xenobiotic-metabolizing enzymes (XME), transporters, nuclear receptors and transcription factors, in(More)
Numerous lung cell lines are currently used as in vitro models for pharmacological and toxicological studies. However, no exhaustive report about the metabolic capacities of these models in comparison with those of lung tissues is available. In the present study, we used a high-throughput quantitative real-time reverse transcription-polymerase chain(More)
Susceptibility to lung diseases, such as lung cancer and chronic obstructive pulmonary disease, is largely influenced by the metabolic capacity of lung tissues. This capacity is partly determined by the expression profile of the cytochromes P450 (CYPs), a superfamily of enzymes that have relevant catalytic properties toward exogenous and endogenous(More)
OBJECTIVES To determine whether CT can depict early perfusion changes in lung cancer treated by anti-angiogenic drugs, allowing prediction of response. METHODS Patients with non-small cell lung cancer, treated by conventional chemotherapy with (Group 1; n = 17) or without (Group 2; n = 23) anti-vascular endothelial growth factor (anti-VEGF) drug(More)
The human cytochrome CYP2A13, which is mainly expressed in the respiratory tract, has been shown to be highly efficient in vitro in the metabolism of tobacco-smoke carcinogens and procarcinogens such as 4-methylnitroso-1-(3-pyridyl)-1-butanone (NNK). In order to investigate the extent of CYP2A13 genetic polymorphism in a French Caucasian population of 102(More)
BACKGROUND Vorinostat is a histone deacetylase inhibitor that changes gene expression and protein activity. On the basis of the clinical benefit reported in patients with malignant pleural mesothelioma treated in a phase 1 study of vorinostat, we designed this phase 3 trial to investigate whether vorinostat given as a second-line or third-line therapy(More)
PURPOSE We evaluated the expression of endocan, a soluble lung- and kidney-selective endothelial cell-specific dermatan sulfate proteoglycan, in non-small cell lung tumors compared with normal lung and studied the significance of high levels of circulating endocan in patients with non-small cell lung cancer. MATERIAL AND METHODS Endocan and vascular(More)
PURPOSE To assess tumor perfusion with multi-detector row computed tomography (CT) in patients with non-small cell lung carcinoma and to correlate CT findings with pathologic results. MATERIALS AND METHODS This study was approved by the local Ethics Committee, and all patients provided written informed consent, which included information on the radiation(More)
The CYP2F1 is a human cytochrome P450 that is selectively expressed in lung tissue and involved in the metabolism of various pneumotoxicants with potential carcinogenic effects. In the present study, we report the first systematic investigation of the genetic polymorphism of this enzyme. We analyzed the nucleotidic sequence of the CYP2F1 gene in DNA samples(More)
Primary ciliary dyskinesia (PCD) is an inherited chronic respiratory obstructive disease with randomized body laterality and infertility, resulting from cilia and sperm dysmotility. PCD is characterized by clinical variability and extensive genetic heterogeneity, associated with different cilia ultrastructural defects and mutations identified in >20 genes.(More)
