Introduction: Cigarette smoking is a major environmental risk factor for many diseases, including chronic obstructive pulmonary disease (COPD). There are shared genetic influences on cigarette smoking and COPD. Genetic risk factors for cigarette smoking in cohorts enriched for COPD are largely unknown. Methods: We performed genome-wide association analyses for average cigarettes per day (CPD) across the COPDGene Non-Hispanic White (NHW) (n=6,659) and African American (AA) (n=3,260), GenKOLS (n=1,671), and ECLIPSE (n=1,942) cohorts...

The present study assessed the association between the variants of macrophage scavenger receptor (MSR)1 and chronic obstructive pulmonary disease (COPD), with or without lung cancer in China. COPD and lung cancer were previously regarded as two separate diseases. However, it has since been reported that there are close associations between COPD and lung cancer. Lung cancer may be an outcome of COPD. COPD may also coexist with lung cancer, and patients with COPD with lung cancer tend to have increased mortality...

We investigated the association between genetic polymorphisms of IL17A, TLR4 and P2RX7 genes and chronic obstructive pulmonary disease (COPD) in a Han population. We performed a case-control study with 152 COPD subjects from the Third People's Hospital of Nantong in 2015. Healthy controls were selected from a group of people attending the physical examination and were frequency-matched to the cases by sex and age. Genotyping was performed using TaqMan allelic discrimination technology. A logistic regression model was used to calculated odds ratios (OR) and 95% confidence intervals (CI)...

Chronic obstructive pulmonary disease (COPD) is a severe lung disease characterized by long-term breathing problems. A series of studies have indicated that the glutathione S-transferase (GST) genes M1 and T1 are associated with COPD susceptibility; however, the result still remains inconclusive. This meta-analysis was performed to estimate the effect of GSTM1 and GSTT1 polymorphisms in COPD risk. Eligible case-control studies published between January 2000 and December 2017 was searched and retrieved. A total of 37 articles were screened out, including 4674 COPD patients and 5006 controls...

BACKGROUND: Two recent genome-wide association studies (GWASs) reported that the FAM13A gene at the 4q22 locus associated with pulmonary fibrosis (defined by rs2609255) overlapping with COPD (defined by rs6837671). We hypothesized that single-nucleotide polymorphisms (SNPs) related to lung disease (especially pulmonary fibrosis) identified in this region are also associated with the risk of silicosis. METHODS: To test this hypothesis, we genotyped these two SNPs (rs2609255 and rs6837671) in a case-control study including 177 silicosis cases and 204 controls with silica dust exposure years similar to the levels for cases in a Chinese population...

Background: Previous studies have suggested that β2 -adrenergic receptor ( ADRB2 ) is associated with COPD. However, the role of genetic polymorphisms in ADRB2 on COPD has not been evaluated yet. Methods: In this study, SNaPshot genotyping, luciferase assay, chromatin immunoprecipitation and real-time polymerase chain reaction were adopted to investigate the association between ADRB2 genetic polymorphisms and COPD, comprehensively. Results: One single nucleotide polymorphism (rs12654778), located upstream of ADRB2 , showed a significant association with COPD by the logistic regression analysis after adjusting for age, sex and smoking history ( p =0...

Juan M Reséndiz-Hernández, Ramcés Falfán-Valencia
Asthma and chronic obstructive pulmonary disease (COPD) are widely documented diseases with an inflammatory component. Asthma is a heterogeneous disorder of the airways that involves chronic inflammation, decline of the airway function and tissue remodeling. Chronic obstructive pulmonary disease is a preventable and treatable disease, which is characterized by persistent limited airflow, and is usually progressive with an increased inflammatory response in the airways. The inflammatory response is evoked by the stimulus of noxious particles and gases...

Background: Smoking and smoke from biomass burning (BB) are the main environmental risk factors for COPD. Clinical differences have been described between COPD related to smoking and related to wood smoke, but no studies have shown genetic differences between patients exposed to these two risk factors. Methods: To investigate a possible association of tumor necrosis factor ( TNF ) promoter polymorphisms, we conducted a case-control study. A total of 1,322 subjects were included in four groups: patients with a diagnosis of COPD secondary to smoking (COPD-S, n=384), patients with COPD secondary to biomass burning (COPD-BB, n=168), smokers without COPD (SWOC, n=674), and biomass burning-exposed subjects (BBES n=96)...

PURPOSE OF REVIEW: Genomic mutations in telomere-related genes have been recognized as a cause of familial forms of idiopathic pulmonary fibrosis (IPF). However, it has become increasingly clear that telomere syndromes and telomere shortening are associated with various types of pulmonary disease. Additionally, it was found that also single nucleotide polymorphisms (SNPs) in telomere-related genes are risk factors for the development of pulmonary disease. This review focuses on recent updates on pulmonary phenotypes associated with genetic variation in telomere-related genes...

Susceptibility to chronic obstructive pulmonary disease (COPD) beyond cigarette smoking is incompletely understood, although several genetic variants associated with COPD are known to regulate airway branch development. We demonstrate that in vivo central airway branch variants are present in 26.5% of the general population, are unchanged over 10 y, and exhibit strong familial aggregation. The most common airway branch variant is associated with COPD in two cohorts ( n = 5,054), with greater central airway bifurcation density, and with emphysema throughout the lung...

BACKGROUND: Genome-wide association studies (GWAS) have identified single nucleotide polymorphisms (SNPs) significantly associated with chronic obstructive pulmonary disease (COPD). However, many genetic variants show suggestive evidence for association but do not meet the strict threshold for genome-wide significance. Integrative analysis of multiple omics datasets has the potential to identify novel genes involved in disease pathogenesis by leveraging these variants in a functional, regulatory context...

Many complex diseases like diabetes, hypertension, metabolic syndrome, et cetera, are measured by multiple correlated phenotypes. However, most genome-wide association studies (GWAS) focus on one phenotype of interest or study multiple phenotypes separately for identifying genetic variants associated with complex diseases. Analyzing one phenotype or the related phenotypes separately may lose power due to ignoring the information obtained by combining phenotypes, such as the correlation between phenotypes. In order to increase statistical power to detect genetic variants associated with complex diseases, we develop a novel method to test a weighted combination of multiple phenotypes (WCmulP)...

The polymorphisms of cytokine genes has been reported to modulate the individual's susceptibility to environmental stimuli in COPD development. C-X-C motif chemokine 10 (CXCL10) mediates recruitment inflammatory cells such as monocytes. Therefore, it may play a key role in COPD. Here, a case-control study was conducted to evaluate the association between CXCL10 tag-SNPs and COPD risk. Four tag-SNPs including rs4256246, rs4508917, rs56061981, and rs56316945 were identified based on the linkage disequilibrium (LD) analysis in 30 healthy controls...

COPD (chronic obstructive pulmonary disease) is characterized by irreversible lung airflow obstruction. Cigarette smoke is the major risk factor for COPD development. However, only a minority number of smokers develop COPD, and there are substantial variations in lung function among smokers, suggesting that genetic determinants in COPD susceptibility. During the past decade, genome-wide association studies and exome sequencing have been instrumental to identify the genetic determinants of complex traits, including COPD...
