Repeated exposure and switching study of cigarette smoke and next generation tobacco product using 3D human bronchial epithelial cells

ABSTRACT: Next generation product such as heat-not-burn type product and e-cigarette emit lower yields of chemical constituents than cigarette because combustion of tobacco leaves is not associated with their vapor generation. Therefore it is expected that the usage of these product bring beneficial impact on public health. However, risk-reduced potential as well as risk concerns in long-term use of these products has not yet been fully understood. In this study, we intended to estimate the risk reduced potential of our proprietary novel tobacco vapor product (NTV) by repeated exposure of in vitro 3D bronchial epithelial cells to NTV vapor in comparison with repeated exposure to cigarette smoke. In addition, to reflect the realistic situation of smokers, exposure switching from cigarette smoke to NTV vapor and cigarette smoke exposure cessation were conducted.

Organotypic human bronchial epithelial cultures (MucilAir) exposed to mainstream aerosols from the 3R4F cigarette and a novel tobacco vapor product

Project description:Cigarette smoke (CS) is an aerosol containing more than 6,000 chemicals and one of the risk factor in the development of chronic inflammatory lung disease. To evaluate biological effect of CS on human respiratory tract, organotypic bronchial epithelial cultures can be used to replicate in vivo tissue conditions. The MucilAir organotypic bronchial epithelial cultures were exposed to mainstream aerosols from the 3R4F cigarette and a novel tobacco vapor product (NTV), which we recently developed, using a Vitrocell exposure system. This system consists of three steps: the generation of CS, dilution, and exposure to an air-liquid interface cultured cells in a specially designed module. This exposure scenario mimics CS exposure in the human airway (i.e. direct aerosol exposure to the apical surface of air-liquid interface-cultured cells), We found a dose-dependent increase in the number of differentially expressed genes following 3R4F cigarette smoke exposure, compared with expression in air-exposed controls. In contrast, no changes were detected following exposure to NTV vapor.

Organotypic human bronchial epithelial cultures (MucilAir) exposed to aqueous aerosol extracts of the 3R4F cigarette smoke and a novel tobacco product vapor

Project description:The current study was performed for analysis of the biological effects of vapor from novel tobacco vapor product in comparison with 3R4F cigarette smoke. This study was performed using a three-dimensional culture system composed of an air-liquid interface culture of primary normal human bronchial epithelial cells (MucilAir). The MucilAir tissues were subjected to 17 days of exposure to the aqueous extract of novel tobacco product vapor or 3R4F cigarette smoke. The number of differentially expressed genes increased in MucilAir tissues exposed to aqueous extract of each test product dependent on exposure duration. The number of differentially expressed genes was lower in the tissues exposed to aqueous extract of novel tobacco product vapor compared to the tissues exposed to aqueous extract of 3R4F cigarette smoke.

A 6-month systems toxicology inhalation study in ApoE−/− mice demonstrates reduced cardiovascular effects of E-vapor aerosols compared to cigarette smoke.

Project description:Smoking cigarettes is harmful to the cardiovascular system. Considerable attention has been paid to the reduced harm potential of alternative nicotine-containing inhalable products such as e-cigarettes. We investigated the effects of E-vapor aerosols or cigarette smoke (CS) on atherosclerosis progression, cardiovascular function, and molecular changes in the heart and aorta of female ApoE−/− mice. The mice were exposed to aerosols from three different E-vapor formulations: (1) carrier (propylene glycol and vegetable glycerol), (2) base (carrier and nicotine) or (3) test (base and flavor) or to CS from 3R4F reference cigarettes for up to 6 months. Concentrations of CS and base or test aerosols were matched at 35 µg nicotine/L. Exposure to CS, compared with sham-exposed fresh air controls, accelerated atherosclerotic plaque formation, while no such effect was seen for any of the three E-vapor aerosols. Molecular changes indicated disease mechanisms related to oxidative stress and inflammation in general, plus changes in calcium regulation, and altered cytoskeletal organization and microtubule dynamics in the left ventricle. While ejection fraction, fractional shortening, cardiac output, and isovolumic contraction time remained unchanged following E-vapor aerosols exposure, the nicotine-containing base and test aerosols caused an increase in isovolumic relaxation time similar to CS. A nicotine-related increase in pulse wave velocity and arterial stiffness was also observed, but it was significantly lower for base and test aerosols than for CS. These results demonstrate that in comparison with CS, E-vapor aerosols induce substantially lower biological responses associated with smoking-related cardiovascular diseases.

Expression data from adult mouse testis exposed to cigarette smoke in utero

Project description:In the context of male reproductive health, epidemiological studies have observed reduced testis size and abnormal sperm counts and morphology in adult men exposed in utero, although these findings are not always repeated. The ambiguity of these reports is confounded by a lack of controlled animal studies investigating the effects of maternal cigarette smoke exposure on male offspring reproductive health. In this study we examined the effects of cigarette induced reproductive toxicity on male offspring exposed during the gestational and weaning period using our novel direct nasal exposure mouse model of cigarette smoke-induced chronic obstructive pulmonary disease and female subfertility. This was done too gain a better understanding of the adverse effects of gestational maternal smoking on male offspring fertility. C57BL/6 5 week-old female mice were exposed via the nose-only to cigarette smoke [twelve 3R4F reference cigarettes (University of Kentucky, USA) twice/day, five times per week, for 12-18 weeks]. Each exposure lasted 60 minutes. Control mice received room air. In total, 27 mice underwent cigarette smoke exposure. Eleven week-old female mice exposed to cigarette smoke for 6 weeks were separated into groups of three and housed with a single control stud male aged 7-8 weeks with proven fertility for a maximum of 12 weeks. Females were monitored every second day for post-coital plugs and pregnancy. Pregnant females were separated into single cages and litter sizes/pup weights recorded. Smoke exposure via dams continued throughout mating/pregnancy/lactation until weaning of pups at 21days post birth. The testis of exposed offspring were then collected for RNA extraction and hybridization on an Illumina Sentrix Mouse ref-8 v2 Beadchip

A 7-month inhalation toxicology study in C57BL/6 mice demonstrates reduced pulmonary inflammation and emphysema following smoking cessation or switching to e-vapor products.

Project description:Cigarette smoking causes serious diseases, including lung cancer, heart disease, and emphysema. While cessation remains the most effective approach to minimize smoking-related disease, alternative non-combustible tobacco-derived nicotine containing products may reduce disease risks among those unable or unwilling to quit. E-vapor aerosols typically contain significantly lower levels of smoke-related harmful and potentially harmful constituents; however, health risks of long-term inhalation exposures are unknown. We designed a 7-month inhalation study in C57BL/6 mice to evaluate long-term respiratory toxicity of e-vapor aerosols compared to cigarette smoke and to assess the impact of smoking cessation or switching to an e-vapor product after 3 months of exposure to 3R4F cigarette smoke (CS). There were no significant changes in in-life observations (body weights, clinical signs) in e-vapor groups compared to the Sham Control. The 3R4F CS group showed reduced respiratory function during exposure and had lower body weight and showed transient signs of distress post-exposure. Following 7 months of exposure, e-vapor aerosols resulted in no or minimal increase in pulmonary inflammation, while exposure to 3R4F CS led to impairment of lung function and caused marked lung inflammation and emphysematous changes. Biological changes observed in the Switching group were similar to the Cessation group. 3R4F CS exposure dysregulated lung and nasal tissue transcriptome, while these molecular effects were substantially lower in the e-vapor group. Results from this study demonstrate that in comparison with 3R4F CS, e-vapor aerosols induce substantially lower biological responses including pulmonary inflammation and emphysema, and that complete switching from CS to e-vapor products significantly reduces biological changes associated with cigarette smoke in C57BL/6 mice.

Transcriptomics-based characterization of smoking and cessation effects in mouse muscle

Project description:COPD is a disorder characterized by the progressive development of airflow limitation that is not fully reversible. Cigarette smoke has been generally accepted as the most important of many risk factors for the development of COPD. We used microarray technology to perform comprehensive gene expression profiling of smoke exposure and cessation effects in mouse muscle tissue. Mice received nose-only exposure of 4% mainstream cigarette smoke or air (sham exposure) for 2 hours/day, 5 days/week for 2, 12 or 24 weeks. Mice undergoing smoke cessation received cigarette smoke exposure for 12 weeks, and then sham exposure for 12 weeks.

Biological changes in C57BL/6 mice following 3 weeks of inhalation exposure to cigarette smoke or e-vapor aerosols

Project description:We compared early biological changes in mice after inhalation exposures to cigarette smoke or e-vapor aerosols (MarkTen® cartridge with Carrier, Test-1, or Test-2 formulations; 4% nicotine). Female C57BL/6 mice were exposed to 3R4F cigarette smoke or e-vapor aerosols by nose-only inhalation for up to 4 hours/day, 5 days/week, for 3 weeks. The 3R4F and e-vapor exposures were set to match the target nose port aerosol nicotine concentration (∼41 µg/L). Only the 3R4F group showed postexposure clinical signs such as tremors and lethargy. At necropsy, the 3R4F group had significant increases in lung weight and changes in bronchoalveolar lavage parameters, as well as microscopic findings in the respiratory tract. The e-vapor groups had minimal microscopic changes, including squamous metaplasia in laryngeal epiglottis, and histiocytic infiltrates in the lung (Test-2 group only). The 3R4F group had a higher incidence and severity of microscopic findings compared to any e-vapor group. Transcriptomic analysis also showed that the 3R4F group had the highest number of differentially expressed genes compared to Sham Control. Among e-vapor groups, Test-2 group had more differentially expressed genes but the magnitude of gene expression-based network perturbations in all e-vapor groups was ∼94% less than the 3R4F group. On proteome analysis in the lung, differentially regulated proteins were detected in the 3R4F group only. In conclusion, 3-weeks of 3R4F exposure induced molecular and microscopic changes associated with smoking-related diseases in the respiratory tract, while e-vapor exposures showed substantially reduced biological activities.

Expression data from adult mouse ovaries exposed to cigarette smoke in vivo

Project description:Mammalian females are born with a finite number of non-renewing primordial follicles, the majority of which remain in a quiescent state for many years. Due to their non-renewing nature, these M-bM-^@M-^\restingM-bM-^@M-^] oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms behind cigarette smoke induced ovotoxicity, which is characterised by primordial follicle depletion. C57BL/6 5 week old female mice were exposed to cigarette smoke five times per week, for 12-18 weeks using a custom-designed and purpose-built nose-only, directed flow inhalation and smoke-exposure system. This was done in the hopes of gaining a better understanding of the mechanisms underpinning cigarette smoke induced ovotoxicity. C57BL/6 5 week old female mice were exposed to cigarette smoke (twelve 3R4F reference cigarettes (University of Kentucky, USA) twice/day, 2.7 mg particulate matter) five times per week, for 12-18 weeks using a custom-designed and purpose-built nose-only, directed flow inhalation and smoke-exposure system. Their ovaries were then collected for RNA extraction and hybridization on an Illumina Sentrix Mouse ref-8 v2 Beadchip
