Angiotensin receptor blockade attenuates cigarette smoke-induced lung injury and rescues lung architecture in a murine model

ABSTRACT: TGFβ inhibition attenuates chronic cigarette smoke induced lung injury and rescues lung architecture. AKR/J mice were exposed to Cigarette Smoke (CS) for a period of two months. Some animals received a treatment of Losartan (.6gr/L) orally while exposed (CS Los). These two groups are to be compared to animals that remained in Room Air (RA) and Room Air plus Losartan(0.6g/L) (RA Los) for any changes.

Chronic obstructive pulmonary disease (COPD) is a prevalent smoking-related disease for which no disease-altering therapies currently exist. As dysregulated TGF-β signaling associates with lung pathology in patients with COPD and in animal models of lung injury induced by chronic exposure to cigarette smoke (CS), we postulated that inhibiting TGF-β signaling would protect against CS-induced lung injury. We first confirmed that TGF-β signaling was induced in the lungs of mice chronically exposed ...[more]

Cigarette smoke induces changes in the basement membrane proteins of the corneal endothelium

Project description:Proteome profiling was performed to investigate changes at a molecular level in the mouse corneal endothelium (CE) along with the basement membrane exposed to cigarette smoke (CS). Pregnant mice (gestation days 18-20) were placed in a whole-body exposure smoking chamber and a few days later pups were born. After 3½ months of CS exposure, the Confoscan4 scanning microscope was used to examine the CE of CS-exposed and control (Ct) mice. The CE was peeled under a microscope and maintained as four biological replicates (two male and two female) for CS-exposed and Ct mice; each replicate consisted of 16 CE. The proteome of the CE was investigated through mass-spectrometry using 8-plex isobaric tandem mass tags (TMT). The CE images of CS-exposed and Ct mice revealed a difference in the shape of corneal endothelial cells (CECs) accompanied by a nearly 10% decrease in CEC density (p = 3.0e-0.5) resulting from exposure to CS. The proteome profiling identified a total of 524 proteins exhibiting statistically significant changes in CE from CS-exposed and Ct mice. Importantly, proteins known to be an integral part of the basement membrane including COL4α1, COL4α2, COL4α3, COL4α4, COL4α5, and COL4α6, Col8α1, Col8α2, FN1, etc. exhibited diminished protein levels in the CE of CS-exposed mice. Here, we report the effects of CS on the CE, and our data strongly suggest that CS exposure results in reduced CEC density and diminished concentration of proteins known to be an integral part of the basement membrane.

Investigating the impact of cigarette smoke on pulmonary cellular immune responses to influenza virus at the single cell resolution in mice.

Project description:Single cell RNA-sequencing (scRNAseq) of lung immune cells from mice exposed to room air or cigarette smoke, infected with influenza A virus. Room air saline controls are also included. This analysis facilitates a comparison of cigarette smoke-associated changes to the pulmonary immune environment at the level of individual leukocytes and stromal cells.

Label free DIA proteomic analysis of thoracic lymph from cigarette smoke (CS)-exposed mice

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.

Haploinsufficiency of Hedgehog interacting protein causes increased emphysema induced by cigarette smoke through network rewiring

Project description:BACKGROUND: The HHIP gene, encoding Hedgehog interacting protein, has been implicated in chronic obstructive pulmonary disease (COPD) by genome-wide association studies (GWAS), and our subsequent studies identified a functional upstream genetic variant that decreased HHIP transcription. However, little is known about how HHIP contributes to COPD pathogenesis. METHODS: Here, we exposed Hhip haploinsufficient mice (Hhip+/-) to cigarette smoke (CS) for 6 months to model the biological consequences caused by CS in human COPD risk-allele carriers at the HHIP locus. Gene expression profiling in murine lungs was performed followed by an integrative network inference analysis, PANDA (Passing Attributes between Networks for Data Assimilation) analysis. RESULTS: We detected more severe airspace enlargement in Hhip+/- mice vs. wild-type littermates (Hhip+/+) exposed to CS. Gene expression profiling in murine lungs suggested enhanced lymphocyte activation pathways in CS-exposed Hhip+/- vs. Hhip+/+ mice, which was supported by increased numbers of lymphoid aggregates and enhanced activation of CD8+ T cells after CS-exposure in the lungs of Hhip+/- mice compared to Hhip+/+ mice. Mechanistically, results from PANDA network analysis suggested a rewired and dampened Klf4 signaling network in Hhip+/- mice after CS exposure. CONCLUSIONS: In summary, HHIP haploinsufficiency exaggerated CS-induced airspace enlargement, which models CS-induced emphysema in human smokers carrying COPD risk alleles at the HHIP locus. Network modeling suggested rewired lymphocyte activation signaling circuits in the HHIP haploinsufficiency state. Total RNA was obtained from the lung tissue of C57BL/6J mice exposed to cigarette smoke (CS) or filtered air (air) for 6 months. Six mice from each of four groups with different genotypes (Hhip+/+ or Hhip+/-) and treatments (air or CS) were randomly chosen for gene expression profiling

The Transcriptome of Nrf2-Deficient Mice in Cigarette Smoke-Induced Emphysematous Changes

Project description:Cigarette smoke (CS) imposes a strong oxidative burden on exposed tissues resulting in a severely disturbed oxidant/antioxidant balance, which in the context of chronic exposure is assumed to be a key contributor to CS-related diseases. Because of its emerging central role in orchestrating the general cellular antioxidant response, the pathway leading to the activation of the transcription factor Nrf2 has received mounting attention over the past decade in investigations aimed at elucidating CS-induced patho-physiological mechanisms. To comprehensively characterize the impact of Nrf2 in acute and sub-chronic smoking scenarios, Nrf2 knock-out mice and their wildtype ICR littermates were exposed to either ambient air (sham exposure) or to one of three doses of CS for up to 5 months with two post-exposure endpoints of 1 and 13 days. The lungs of the mice were monitored for transcriptomic changes on a genome-wide level. 110 samples from 28 different groups are analyzed. For each group there are 4 replicates, besides two groups with only 3 replicates. Group parameteres are: genotype (WT, KN), treatment (sham, smoke), dosage of smoke treatment (low, medium, high), time of smoke treatment (1 day, 2 month, 5 month, 5 month + 1 day recovery, 5 month + 13 days recovery)

Systems toxicology assessment of CHTP1.2 [Liver Data]

Project description:Modified risk tobacco products (MRTPs) have the potential to reduce smoking-related health risks. The Carbon Heated Tobacco Product 1.2 (CHTP1.2) is a potential MRTP that uses a pressed carbon heat source to generate an aerosol by heating tobacco. This study reports the results from the systems toxicology arm of a 90-day rat inhalation study (OECD test guideline 413) to assess the effects of CHTP1.2 aerosol compared with cigarette smoke (CS). Rats were exposed to filtered air (sham), to CHTP1.2 aerosol (at 15, 23 and 50 µg nicotine / L), or to the 3R4F reference cigarette smoke (at 23 µg nicotine / L).
