ACE gene; Chronic obstructive pulmonary disease; Polymorphism

An insertion/deletion (I/D) polymorphism was identified in intron 16 of the gene encoding the human angiotensin I-converting enzyme (ACE), a candidate gene for chronic obstructive pulmonary disease (COPD). We investigated the relationship between this polymorphism in the ACE gene and the risk of developing COPD. Sixty-six COPD in-patients and 40 non-smoking control individuals ... more

Bronchial carcinoma; Chronic obstructive pulmonary disease; Feature selection; Ion mobility spectrometry; Machine learning

Exhaled air carries information on human health status. Ion mobility spectrometers combined with a multi-capillary column (MCC/IMS) is a well-known technology for detecting volatile organic compounds (VOCs) within human breath. This technique is relatively inexpensive, robust and easy to use in every day practice. However, the potential of this methodology depends on successful ... more

Angiotensin converting enzyme; Chronic obstructive pulmonary disease; Renin angiotensin system; Turkish population

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow obstruction that occurs as a result of the normal inflammatory process to protect against harmful irritants and chemicals. Another physiological regulatory process, the renin angiotensin system (RAS), plays an important role in the pathology of many diseases. Angiotensin converting enzyme (ACE) is a key ... more

Biomarker; Chronic obstructive pulmonary disease; Protein-protein interaction network

Chronic obstructive pulmonary disease (COPD) is a growing cause of morbidity and mortality throughout the world. The purpose of our study was to uncover biomarkers and explore its pathogenic mechanisms at the molecular level. The gene expression profiles of COPD samples and normal controls were downloaded from Gene Expression Omnibus. Matlab was used for data preprocessing and SAM4.0 was ... more

Chronic obstructive pulmonary disease; CYP1A1; Polymorphism; TNFα

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by persistent airflow limitation. Smoking, occupational exposures, air pollution, and genetics are all risk factors. In the present study, we detected the cytochrome P4501A1 gene (CYP1A1) MspI polymorphism and the tumor necrosis factor alpha (TNFα)-308 single nucleotide polymorphism in ... more

Chronic obstructive pulmonary disease; Meta-analysis; Polymorphism; Tumor necrosis factor-alpha

The association between the TNF-α +489 G/A polymorphism and chronic obstructive pulmonary disease (COPD) remains controversial because of small group size and varied design among different studies. In the present study, a meta-analysis was conducted to assess the association between the +489 G/A polymorphism and COPD risk. A comprehensive search was conducted to identify ... more

Chronic obstructive pulmonary disease; Interleukin-1β; Polymorphism

Studies examining the role of interleukin (IL)-1β -511C/T promoter polymorphism in the pathogenesis of chronic obstructive pulmonary disease (COPD) have shown inconsistent results. This meta-analysis was performed to assess the association between the IL-1β-511C/T promoter polymorphism and COPD susceptibility. Published case-control, cross-sectional, and cohort studies ... more

Chronic obstructive pulmonary disease; Polymorphism; Vitamin D-binding protein

Vitamin D-binding protein (DBP), a highly polymorphic serum protein, encoded by GC gene, is important in the development of chronic obstructive pulmonary disease (COPD). This meta-analysis was performed to assess the association between GC polymorphisms (1F, 1S, and 2 alleles) and COPD susceptibility. Published case-control studies were retrieved from the Pubmed, Embase, and China ... more

The objective of this study was to investigate the correlation between spicular signs on computed tomography (CT) scans and peripheral lung cancer (PLC) that is associated with interstitial lung disease (ILD) and chronic obstructive pulmonary disease (COPD). We analyzed clinical data from 96 PLC cases and grouped patients based on whether they had interstitial pneumonia into either ILD/ ... more

Association analysis; Genetic variation; Goat; Production traits; Sine oculis homeobox homolog 6 (Six6) gene

We looked for novel genetic variations within the Six6 gene by PCR-SSCP, DNA sequencing and forced RFLP-PCR and estimated their associations with production traits in 2132 goats of eight indigenous Chinese breeds. A novel single nucleotide polymorphism (NM_001104993.1: g.232T>C) within the goat Six6 gene was identified. The frequencies of allele “C” varied from 0.8621 ... more
