Project description:Exposure to electronic cigarette (e-cigarette) aerosol has been linked to a number of health concerns, including DNA damage, elevated oxidative stress, release of inflammatory cytokine, and dysfunctions in epithelial barriers. However, little is known about the effect of exclusive e-cigarette use on expression profiles of exosomal miRNAs, which play critical regulatory roles in many inflammatory responses and disease process including cancer. We aim to compare the exosomal microRNAs expression profile between exclusive e-cigarette users and normal controls without any tobacco product use (non-users). Using blood and urine samples from exclusive e-cigarette users and non-users in the Population Assessment of Tobacco and Health (PATH) Wave 1 study (2013-2014), we examined exosomal microRNAs expression levels through Illumina NextSeq 500/550 sequencing. We identified microRNAs that have significantly higher expression levels in exclusive e-cigarette users than non-users. Gene enrichment analysis of these significant exosomal microRNAs showed their involvement in cancer related pathways, which might indicate a potential elevated risk of cancer among exclusive e-cigarette users.

Project description:Background: Waterpipe (hookah, shisha, narghile), a worldwide, commonly used method to smoke tobacco, is considered “safe” by its users because the smoke is “filtered” by water before inhalation. Based on the knowledge that lung cells take the brunt of inhaled smoke, we hypothesized that even mild waterpipe smoking is associated with disordering of lung biology. Methods: Young (25±4 yr), mild (3.5±2.5 sessions/wk for 4.1±2.5 years) waterpipe smokers with no history of cigarette smoking (n=21) were assessed in comparison to nonsmokers (33±9 yr, n=19) for routine clinical paramters, lung epithelial lining fluid metabolome, small airway epithelial (SAE) cell differential and transcriptome, alveolar macrophage (AM) transcriptome, plasma endothelial cell microparticles (EMPs), cough and sputum scores, lung function, chest HRCT. Results: Compared to nonsmokers, waterpipe smokers had increased levels of blood carboxy-hemoglobin, an abnormal epithelial lining fluid metabolome profile, increased proportions of SAE secretory and intermediate cells, reduced proportions of ciliated and basal cells, markedly abnormal SAE and AM transcriptomes, elevated levels of EMPs derived from apoptotic pulmo-nary endothelium, more cough and sputum, and lower diffusion capacity (DLCO). Conclusions: Young, mild-use waterpipe-only smokers have a variety of abnormalities in multiple lung-related biologic and clinical parameters, suggesting that even limited waterpipe use may be linked to lung disease, i.e., waterpipe smoking may be associated with a significant public health risk.

Project description:Previous reports showed that cigarette smoke exposed normal-appearing airways in phenotypically lung cancer-free smokers carry alterations that are characteristic of tumors – suggestive of an airway field of injury. Very little is known of the effects of the chronic consumption of other forms of tobacco, such as waterpipe smoke (WPS), on lung pathobiology. Here we studied normal-appearing airway brushings from waterpipe smokers and those who were not exposed to WPS. We find that WPS elicits a molecular field of injury with gene programs that are pertinent to lung carcinogenesis.

Project description:Waterpipe (also called hookah, shisha, or narghile) smoking is a common form of tobacco use in the Middle East. Its use is becoming more prevalent in Western societies, especially among young adults as an alternative form of tobacco use to traditional cigarettes. While the risk to cigarette smoking is well documented, the risk to waterpipe smoking is not well defined with limited information on its health impact at the epidemiologic, clinical and biologic levels with respect to lung disease. Based on the knowledge that airway epithelial cell DNA methylation is modified in response to cigarette smoke and in cigarette smoking-related lung diseases, we assessed the impact of light-use water-pipe smoking on DNA methylation of the small airway epithelium (SAE) and whether changes in methylation were linked to the transcriptional output of the cells. Small airway epithelium was obtained from 7 nonsmokers and 7 light-use (2.6 ± 1.7 sessions/wk) waterpipe-only smokers. Genome-wide comparison of SAE DNA methylation of waterpipe smokers to nonsmokers identified 727 probesets differentially methylated (fold-change >1.5, p<0.05) representing 673 unique genes. Dominant pathways associated with these epigenetic changes include those linked to G-protein coupled receptor signaling, aryl hydrocarbon receptor signaling and xenobiotic metabolism signaling, all of which have been associated with cigarette smoking and lung disease. Of the genes differentially methylated, 11.3% exhibited a corresponding significant (p<0.05) change in gene expression with enrichment in pathways related to regulation of mRNA translation and protein synthesis (eIF2 signaling and regulation of eIF4 and p70S6K signaling). Overall, these data demonstrate that light-use waterpipe smoking is associated with epigenetic changes and related transcriptional modifications in the SAE, the cell population demonstrating the earliest pathologic abnormalities associated with chronic cigarette smoking. This study demonstrates that light-use waterpipe smoking in young adults is associated with a broad range of genome-wide DNA methylation-related changes of the SAE impacting a number of genes linked to pathways previously associated with cigarette smoking. Further, many of these methylation-related changes correlate with waterpipe smoking-associated changes in the SAE transcriptome. Together, these data add to the accumulating evidence that waterpipe smoking is harmful, and may lead to lung disease.

Project description:Objectives: To identify transcriptomic differences in the blood and sputum of e-cigarette users compared to conventional cigarettes smokers and healthy controls and describe biological pathways affected by these tobacco products. Methods: Cross-sectional analysis of whole blood and sputum RNA-sequencing data from 8 smokers, 9 e-cigarette users (e-cigs) and 4 controls. Weighted gene co-network analysis (WGCNA) identified gene module associations. Ingenuity Pathway Analysis (IPA) identified canonical pathways associated with tobacco products. Main Results: In blood, a three-group comparison showed 16 differentially expressed genes (DEGs); pair-wise comparison showed 7 DEGs between e-cigs and controls, 35 DEGs between smokers and controls, and 13 DEGs between smokers and e-cigs. In sputum, 438 DEGs were in the three-group comparison. In pair-wise comparisons, there were 2 DEGs between e-cigs and controls, 270 DEGs between smokers and controls, and 468 DEGs between smokers and e-cigs. Only 2 genes in the smokers vs. control comparison overlapped between blood and sputum. Most gene modules identified through WGCNA associated with tobacco product exposures also were associated with cotinine and exhaled CO levels. IPA showed multiple canonical pathways altered by conventional smoking but none by e-cigarette use. Conclusion: Cigarette smoking and e-cigarette use led to transcriptomic changes in both blood and sputum. However, conventional cigarettes induced much stronger transcriptomic responses in both compartments.

Project description:Little is known about alteration of the global gene expression by cigarette smoke (CS) and few biomarkers for smoking-related harm are available. We used Affymetrix HG-U133A GeneChips to measure the transcriptomes in lymphocytes of 23 current healthy smokers. When heavy smokers were compared with light smokers, 311 genes demonstrated a significant difference in mRNA expression of their blood lymphocytes. Experiment Overall Design: The goals of this study were to evaluate novel gene expression profiles and pathways affected by cigarette smoking, and to identify potential biomarkers for cigarette smoke exposure and harm. To this end, we isolated the PBMC from 10 heavy and 13 light smokers, determined their gene expression profiles with Affymetrix microarray and analyzed their relationship with cigarette smoking.
