Project description:Lung antigen presenting cells isolated from wild type but not Spp1-/- mice induce Th1 and Th17 cells differentiation. The goal of this study is to identify the genes differentially expressed by lung antigen presenting cells from cigarette smoke exposed mice. These genes may play crucial roles in directing Th1 and Th17 cells differentiation. Lung antigen presenting cells were isolated from lungs of two groups of wild type and Spp1-/- mice that have been exposed to cigarette smoke for 4 months. Total mRNA was extracted from these samples.

Project description:The lymphatic vasculature is critical for lung function, but defects in lymphatic functionin the pathogenesis of lung disease is understudied. To further assess the contribution of lymphatics to the pathogenesis of lung emphysema we used a mouse model of cigarette smoke (CS)-induced emphysema, and analyzed lung lymphatics using immunohistochemistry, functional assays, and confocal microscopy. Additionally, we further harvested thoracic lymph from CS-exposed mice for proteomic analysis. In this presented section of our research, we highlight the label free quantitative DIA proteomics approaches used to profile the proteomic and peptidomics changes in the lymph from cigarette smoke (CS)-mice as compared with the lymph proteome from mice exposed to room air. Label free quantitative DIA proteomics analysis of lymph confirmed upregulation of coagulation and inflammatory pathways in the lymphatics of CS-exposed mice compared to control mice.

Project description:These studies tested the hypotheses that smoke induces changes in mRNA profiles that are dependent on sex and the health status of the lung, and that the effects of smoke are different after 1 day compared to 5 days of smoke exposure. The ways in which the lungs modulate their response to cigarette smoke after repeated exposures are important for understanding the toxicology of smoke, for developing biomarkers of chronic smoke exposure, and for understanding the therapeutic potential in regulatory signaling pathways that are beneficial or detrimental to lung health. Sex-matched 5-7-week old wildtype (WT) and Scnn1b-overexpressing (BENaC) littermates were exposed to cigarette smoke or sham (room air) exposure. Exposure occurred in a plexiglass chamber attached to a smoke delivery device using an exposure chamber and smoking machine (inExpose Exposure System, SCIREQ, Chandler, AZ). Mice were exposed to mainstream + sidestream smoke from 6 reference cigarettes with filters removed per day (3R4F research cigarettes, University of Kentucky). Each cigarette was puffed for 2 sec every 25 sec, using the standard Federal Trade Commission smoking machine protocol. The sham-exposed control mice were exposed to room air in the exposure chamber for a time equivalent to that needed for active smoke exposure. Mice were exposed to cigarette or sham smoke for 1 day or 5 consecutive days. Samples were harvested 4 hours after the completion of the final smoke exposure. The right lung was used for gene expression analysis.

Project description:We have investigated the effects of cigarette smoke exposure in three different strains of mice. DBA/2 and C57Bl/6J are susceptible to smoke and develop different lung changes in response to chronic exposure, while ICR mice are resistant to smoke and do not develop emphysema. The present study was carried out to determine early changes in the gene expression profile of mice exposed to cigarette smoke with either a susceptible or resistant phenotype. Experiment Overall Design: Three strains of mice were exposed to smoke from three cigarette/day, 5d/wk for 4 weeks. Microarray analysis was carried out on total RNA extracted from the lung utilizing the Affymetrix platform.

Project description:Proteasome dysfunction is emerging as a novel pathomechanism for the development of chronic obstructive pulmonary disease (COPD), a major leading cause of death in the world. Cigarette smoke is one of the main risk factors for COPD and has been shown to impair proteasome function in vitro and in vivo. Importantly, proteasome activity is inhibited in COPD lungs while expression levels of proteasome subunits are not altered. In the present study, we dissected the molecular changes induced by cigarette smoke on proteasome function in lung epithelial cells and mouse lungs. We analyzed the integrity, composition, and the interactome of isolated 26S proteasome complexes from smoke-exposed cells and mouse lungs. Moreover, we applied native MS analysis to investigate whether reactive compounds of cigarette smoke directly modify and inhibit the 20S proteasome complex. Our data reveal that the 20S proteasome is slightly destabilized in the absence of any dominant modification of proteasomal proteins. 26S pulldown and stoichiometry analysis indicated that 26S proteasome complexes become instable in response to cigarette smoke exposure. Of note, the interactome of the 26S was clearly altered in smoke-exposed mouse lungs possibly reflecting an altered cellular composition in the lungs of the smoke-exposed mice. Taken together, our results suggest that cigarette smoke induces minor but detectable changes in the stability and interactome of 20S and 26S proteasome complexes which might contribute in a chronic setting to imbalanced proteostasis as observed in chronic lung diseases associated with cigarette smoking.

Project description:How LTβR-signalling drives chronic tissue damage particularly in the lung, which mechanisms regulate this process, and whether LTβR-blockade might be of therapeutic value has remained unclear. To study the mechanisms underlying LTβR-inhibition, a transcriptional analysis was performed on lung tissue from B6 mice exposed to cigarette smoke for 6 months and treated therapeutically with LTβR-Ig from 4 to 6 months compared to mice exposed to cigarette smoke for 6 months and treated with control Ig from 4 to 6 months and filtered air control. Single-cell RNA-Seq identified 24 distinct cell populations across >20,000 cells in lungs with distinct changes occurring upon cigarette smoke exposure and LTβR-Ig treatment.

Project description:We hypothesize that gene expression in the cigarette smoke (CS) exposed neonatal lung and age-matched controls will be divergent. CS exposed lung will have divergence of immune response genes and structural genes. The lungs of (6) 2 week old neonatal mice exposed to 2 weeks of CS were compared to the lung of (4) 2 week old age-matched control mice. We utilized microarray analysis to examine transcriptional differences between smoke exposed neonatal lung and age-matched controls. Keywords: comparative expression profiling
