[PMID: 36115827 DOI: 10.1016/j.pulmoe.2021.07.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 05/06/2021] [Accepted: 07/24/2021] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a complex disease characterized by limited airflow and is influenced by genetic and environmental factors. The purpose of this study was to investigate the effects of gene polymorphisms in MIR5708 and MIR1208 on COPD risk. METHODS Four single nucleotide polymorphisms (SNPs) in MIR5708 (rs6473227 and rs16907751) and MIR1208 (rs2608029 and rs13280095) were selected and genotyped among 315 COPD patients and 314 healthy controls using the Agena MassARRAY platform. SPSS 18.0 was used for statistical analysis and data processing. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between genetic variants of MIR1208 and MIR5708 and COPD risk. RESULTS The results suggested that rs16907751 variants in MIR5708 contributed to an increased susceptibility to COPD in the allelic (P = 0.001), co-dominant (homozygous) (P = 0.001), dominant (P = 0.017), recessive (P = 0.002), and additive (P = 0.002) models. The effects of MIR5708 and MIR1208 gene polymorphisms on the risk of COPD were age-, sex-, smoking status-, and BMI-related. Furthermore, the C-A and G-A haplotypes of rs2608029 and rs13280095 in MIR1208 were identified as risk factors for COPD in the population over 70 years (P = 0.029) and in women (P = 0.049), respectively. Finally, significant associations between rs16907751genotypes with pulse rate and forced expiratory volume in 1 s were found among COPD patients. CONCLUSION Genetic polymorphisms in MIR5708 and MIR1208 are associated with increased risk of COPD in China.

A novel non-invasive method allowing for discovery of pathologically relevant proteins from small airways. Clin Proteomics 2022; 19:20. [PMID: 35668386 PMCID: PMC9167914 DOI: 10.1186/s12014-022-09348-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 04/04/2022] [Indexed: 01/01/2023] Open
Abstract
Background There is a lack of early and precise biomarkers for personalized respiratory medicine. Breath contains an aerosol of droplet particles, which are formed from the epithelial lining fluid when the small airways close and re-open during inhalation succeeding a full expiration. These particles can be collected by impaction using the PExA method (Particles in Exhaled Air), and are derived from an area of high clinical interest previously difficult to access, making them a potential source of biomarkers reflecting pathological processes in the small airways. Research question Our aim was to investigate if PExA method is useful for discovery of biomarkers that reflect pathology of small airways. Methods and analysis Ten healthy controls and 20 subjects with asthma, of whom 10 with small airway involvement as indicated by a high lung clearance index (LCI ≥ 2.9 z-score), were examined in a cross-sectional design, using the PExA instrument. The samples were analysed with the SOMAscan proteomics platform (SomaLogic Inc.). Results Two hundred-seven proteins were detected in up to 80% of the samples. Nine proteins showed differential abundance in subjects with asthma and high LCI as compared to healthy controls. Two of these were less abundant (ALDOA4, C4), and seven more abundant (FIGF, SERPINA1, CD93, CCL18, F10, IgM, IL1RAP). sRAGE levels were lower in ex-smokers (n = 14) than in never smokers (n = 16). Gene Ontology (GO) annotation database analyses revealed that the PEx proteome is enriched in extracellular proteins associated with extracellular exosome-vesicles and innate immunity. Conclusion The applied analytical method was reproducible and allowed identification of pathologically interesting proteins in PEx samples from asthmatic subjects with high LCI. The results suggest that PEx based proteomics is a novel and promising approach to study respiratory diseases with small airway involvement. Supplementary Information The online version contains supplementary material available at 10.1186/s12014-022-09348-y. Key question Can the PExA method identify individual protein profiles that reflect pathology of small airways, using the SOMAscan platform? What is the bottom line? Two hundred-seven proteins were detected in up to 80% of the PEx samples, with a strong overrepresentation of proteins related to innate immune responses, including nine proteins that that discriminated subjects with asthma and high LCI as compared to healthy controls. Why read on The results support that PEx based proteomics is a novel and promising approach to study respiratory diseases with small airway involvement. Supplementary Information The online version contains supplementary material available at 10.1186/s12014-022-09348-y.

Mmp12 Is Upregulated by in utero Second-Hand Smoke Exposures and Is a Key Factor Contributing to Aggravated Lung Responses in Adult Emphysema, Asthma, and Lung Cancer Mouse Models. Front Physiol 2021; 12:704401. [PMID: 34912233 PMCID: PMC8667558 DOI: 10.3389/fphys.2021.704401] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 10/19/2021] [Indexed: 12/18/2022] Open
Abstract
Matrix metalloproteinase-12 (Mmp12) is upregulated by cigarette smoke (CS) and plays a critical role in extracellular matrix remodeling, a key mechanism involved in physiological repair processes, and in the pathogenesis of emphysema, asthma, and lung cancer. While cigarette smoking is associated with the development of chronic obstructive pulmonary diseases (COPD) and lung cancer, in utero exposures to CS and second-hand smoke (SHS) are associated with asthma development in the offspring. SHS is an indoor air pollutant that causes known adverse health effects; however, the mechanisms by which in utero SHS exposures predispose to adult lung diseases, including COPD, asthma, and lung cancer, are poorly understood. In this study, we tested the hypothesis that in utero SHS exposure aggravates adult-induced emphysema, asthma, and lung cancer. Methods: Pregnant BALB/c mice were exposed from gestational days 6–19 to either 3 or 10mg/m3 of SHS or filtered air. At 10, 11, 16, or 17weeks of age, female offspring were treated with either saline for controls, elastase to induce emphysema, house-dust mite (HDM) to initiate asthma, or urethane to promote lung cancer. At sacrifice, specific disease-related lung responses including lung function, inflammation, gene, and protein expression were assessed. Results: In the elastase-induced emphysema model, in utero SHS-exposed mice had significantly enlarged airspaces and up-regulated expression of Mmp12 (10.3-fold compared to air-elastase controls). In the HDM-induced asthma model, in utero exposures to SHS produced eosinophilic lung inflammation and potentiated Mmp12 gene expression (5.7-fold compared to air-HDM controls). In the lung cancer model, in utero exposures to SHS significantly increased the number of intrapulmonary metastases at 58weeks of age and up-regulated Mmp12 (9.3-fold compared to air-urethane controls). In all lung disease models, Mmp12 upregulation was supported at the protein level. Conclusion: Our findings revealed that in utero SHS exposures exacerbate lung responses to adult-induced emphysema, asthma, and lung cancer. Our data show that MMP12 is up-regulated at the gene and protein levels in three distinct adult lung disease models following in utero SHS exposures, suggesting that MMP12 is central to in utero SHS-aggravated lung responses.

Abstract
INTRODUCTION Cytochrome P450 (CYP) 2J2 is a major enzyme that controls epoxyeicosatrienoic acids biosynthesis, which may play a role in chronic obstructive pulmonary disease (COPD) development. In this study, we aimed to assess the influence of CYP2J2 polymorphisms with COPD susceptibility. MATERIAL AND METHODS A case-control study enrolled 313 COPD cases and 508 controls was to investigate the association between CYP2J2 polymorphisms and COPD risk. Agena MassARRAY platform was used to genotype CYP2J2 polymorphisms. Odds ratios (OR) and 95% confidence intervals (CI) were calculated to evaluate the association between CYP2J2 polymorphisms and COPD risk. RESULTS We observed rs11207535 (homozygote: OR=0.08, 95%CI=0.01-0.96, p=0.047; recessive: OR=0.08, 95%CI=0.01-0.94, p=0.044), rs10889159 (homozygote: OR=0.08, 95%CI=0.01-0.92, p=0.043; recessive: OR=0.08, 95%CI=0.01-0.90, p=0.040) and rs1155002 (heterozygote: OR=1.63, 95%CI=1.13-2.36, p=0.009; dominant: OR=1.64, 95%CI=1.15-2.35, p=0.006; additive: OR=1.45, 95%CI=1.09-1.92, p=0.011) were significantly associated with COPD risk. Allelic tests showed T allele of rs2280274 was related to a decreased risk of COPD and T allele of rs1155002 was associated with an increased COPD risk. Stratified analyses indicated the effects of CYP2J2 polymorphisms and COPD risk were dependent on gender and smoking status (p<0.05). Additionally, two haplotypes (Ars11207535Crs10889159Trs1155002 and Ars11207535Crs10889159Crs1155002) significantly decreased COPD risk. CONCLUSION It suggested CYP2J2 polymorphisms were associated with COPD susceptibility in the Chinese Han population.

Abstract
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. RECENT FINDINGS Genomic mutations in seven telomere-related genes cause pulmonary disease. Pulmonary phenotypes associated with these mutations range from many forms of pulmonary fibrosis to emphysema and pulmonary vascular disease. Telomere-related mutations account for up to 10% of sporadic IPF, 25% of familial IPF, 10% of connective-tissue disease-associated interstitial lung disease, and 1% of COPD. Mixed disease forms have also been found. Furthermore, SNPs in TERT, TERC, OBFC1, and RTEL1, as well as short telomere length, have been associated with several pulmonary diseases. Treatment of pulmonary disease caused by telomere-related gene variation is currently based on disease diagnosis and not on the underlying cause. SUMMARY Pulmonary phenotypes found in carriers of telomere-related gene mutations and SNPs are primarily pulmonary fibrosis, sometimes emphysema and rarely pulmonary vascular disease. Genotype-phenotype relations are weak, suggesting that environmental factors and genetic background of patients determine disease phenotypes to a large degree. A disease model is presented wherever genomic variation in telomere-related genes cause specific pulmonary disease phenotypes whenever triggered by environmental exposure, comorbidity, or unknown factors.

Abstract
BACKGROUND Regulator of telomere elongation helicase 1 (RTEL1), a telomere length-related gene, is closely linked to cancer and age-related diseases. The aim of this study was to investigate the association between genetic polymorphisms in the RTEL1 gene and coronary heart disease (CHD) risk. METHODS In this case-control study, which includes samples from 596 CHD patients and 603 healthy controls, five SNPs in RTEL1 were selected. The genotypes were studied using the Agena MassARRAY platform, and the statistical analyses were performed using the chi-square and Fisher's exact tests, genetic model analysis, and haplotype analysis. RESULTS In the allele model, using the chi-square test, we found that the patients with the "G" allele of rs6010620 and the "C" allele of rs4809324 in the RTEL1 gene showed a decreased risk of CHD once the results were adjusted for age and gender. In the genetic model, logistic regression analyses revealed that the rs6010620 polymorphism conferred a decreased risk of CHD in the codominant model (OR = 0.52, 95% CI: 0.31-0.88, p = 0.007 for the "G/G" genotype) and the recessive model (OR = 0.49, 95% CI: 0.30-0.80, p = 0.004 for the "G/G" genotype). In addition, the haplotype "Grs6010620 Trs6010621 Trs4809324 " of RTEL1 was associated with a 0.03-fold decreased risk of CHD once the results were adjusted for age and gender (OR = 0.03, 95% CI: 0.01-0.12, p < 0.001). CONCLUSION Our findings have demonstrated that the genetic variants of RTEL1 may have a protective role against CHD risk.
