(Submitter supplied) Cigarette smoking is the main risk factor for the development of squamous cell lung carcinoma (SCC). However, the smoking-related molecular changes in SCC have not been studied. We wanted to identify genes in both histologically normal bronchial epithelium and SCC samples that are differentially expressed between current and ex-smokers. In addition, to analyze the levels of the smoking-related genes identified in normal bronchial epithelium with the levels in SCC. more...

(Submitter supplied) Genetics of gene expression (eQTLs or expression QTLs) has proved an indispensable tool for understanding biological pathways and pathomechanisms of trait associated SNPs. However, power of most genome-wide eQTL studies is still limited. We performed a large eQTL study in peripheral blood mononuclear cells of 2,112 individuals increasing the power to detect trans-effects genome-wide. Going beyond univariate SNP-transcript associations, we analyse relations of eQTLs to biological pathways, polygenetic effects of expression regulation, trans-clusters, and enrichment of co-localised functional elements. more...

(Submitter supplied) Induced sputum is used to sample inflammatory cells, predominantly neutrophils and macrophages, from the airways of COPD patients. Our aim was to identify candidate genes associated with the degree of airflow obstruction and the extent of emphysema by expression profiling, and then to confirm these findings for selected candidates using specific PCR and protein analysis.

(Submitter supplied) Scientific evidence indicates that genetic factors may contribute to differences in lung cancer risk for individuals with similar levels of tobacco exposure, which is the main environmental risk factor of lung cancer. Moreover, lung cancer patients show large differences in clinical staging and survival; these differences seem to be attributable, at least partially, to the genetic background. The analysis of the molecular properties (e.g., germline variations and genome-wide expression levels) of non-involved tissue from lung cancer patients may contribute in the identification of genetic factors involved in the development and progression of this pathology. more...

(Submitter supplied) Purpose: The goal of this study was to analyze the gene expression levels by RNA sequencing from the plantaris muscle of mice exposed to normal air or tobacco smoke for 16 weeks. Methods: Plantaris muscles were removed, flash frozen, and RNA was harvested using the RNeasy Tissue Mini Kit (Qiagen), according to manufacturer’s instructions. RNA was reverse transcribed to complementary DNA (Lexogen QuantSeq 3′ FWD), and sequenced on a HiSeq 4000 instrument (Illumina). more...

(Submitter supplied) Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease with complex pathological features and largely unknown etiologies. Identification and validation of biomarkers for this disease could facilitate earlier diagnosis, appreciation of disease subtypes and/or determination of response to therapeutic intervention. To identify gene expression markers for COPD, we performed genome-wide expression profiling of lung tissue from 56 subjects using the Affymetrix U133 Plus 2.0 array. more...

(Submitter supplied) Our data demonstrates enrichment of the GO term extracellular region among the decreased lung transcripts of JF1 throughout the process of lung development and maturation in consistent to the altered elastin to collagen ratio. Our microarray data showed increased ~4 fold increased elastin transcripts in JF1 lungs at P70. Specific CL‐saline/air ratio in JF1 mice compared to C3H (JF1-male: 2.68±01.10 versus C3H-male: 2.15±0.42, p<0.05; JF1-female: 3.22±0.88 versus C3H-female: 2.27±0.23, p<0.05) suggests that surface tension contributes more than the elastic recoiling properties of lung in determining the lung compliance as assessed by air filling. more...

(Submitter supplied) We analyzed gene expression profiling of lung tissue to define molecular pathway of COPD using recent RNA sequencing technology.Lung tissue was obtained from 98 COPD subjects and 91 subjects with normal spirometry. RNA isolated from these samples was processed with RNA-seq using HiSeq 2000. Gene expression measurements were calculated using Cufflinks software. Differentially expressed genes and isoforms were chosen using t-test. more...
