AB  - Introduction: Cigarette smoke exposure is a known risk factor for development of lung diseases and
electronic cigarettes (e-cigarettes) were introduced as a popular and safer alternative to combustible tobacco products. Increasing number of studies are reporting their adverse biological effects both in vivo
and in vitro. Aim of this study was to evaluate the effect of e-cigarettes on mitochondrial function in
lung bronchial epithelial cells.
Methods: Electronic cigarette vapor condensate (ECC) was generated using an e-cigarette device on a
suction trap cooled in a dry ice/ethanol bath. We used unflavoured and flavoured e-cigarette liquids with
and without nicotine. Human bronchial epithelial BEAS2B cells were seeded in 96well plates and treated
with 2% e-cigarette vapour condensate for 24h. Mitochondrial membrane potential was measured using
50nM TMRE (Tetramethyl rhodamine ethyl ester) and cells were visualized on ImageXpress® Pico Automated Cell Imaging System (Molecular Devices, San Jose, CA, USA) with a 10x objective.
Results: We found a significant reduction of TMRE fluorescence in treated cells compared to the control. Imaging of treated cells also revealed changes in cell morphology and the presence of mitochondria in TNT-like structures.
Conclusion: Mitochondrial dysfunction has been associated with various pathological conditions including lung diseases such as asthma, COPD and lung cancer. Due to their relative novelty, the role of
electronic cigarette use in development of chronic lung diseases is still relatively unknown. Our findings
contribute to the growing list of studies pointing to their adverse biological effects and imply their involvement in processes contributing to chronic lung diseases.

AB  - BACKGROUND Although still considered a safer alternative to classical cigarettes, growing body of work points to harmful effects of electronic cigarettes (e-cigarettes) affecting a range of cellular processes. The biological effect of e-cigarettes needs to be investigated in more detail considering their widespread use. METHODS In this study, we treated V79 lung fibroblasts with sub-cytotoxic concentration of e-cigarette liquids, with and without nicotine. Mutagenicity was evaluated by HPRT assay, genotoxicity by comet assay and the effect on cellular communication by metabolic cooperation assay. Additionally, comprehensive proteome analysis was performed via high resolution, parallel accumulation serial fragmentation-PASEF mass spectrometry. RESULTS E-cigarette liquid concentration used in this study showed no mutagenic or genotoxic effect, however it negatively impacted metabolic cooperation between V79 cells. Both e-cigarette liquids induced significant depletion in total number of proteins and impairment of mitochondrial function in treated cells. The focal adhesion proteins were upregulated, which is in accordance with the results of metabolic cooperation assay. Increased presence of posttranslational modifications (PTMs), including carbonylation and direct oxidative modifications, was observed. Data are available via ProteomeXchange with identifier PXD032071. CONCLUSIONS Our study revealed impairment of metabolic cooperation as well as significant proteome and PTMs alterations in V79 cells treated with e-cigarette liquid warranting future studies on e-cigarettes health impact.
