Effect of cigarette smoke on SARS-CoV-2-induced ACE2 and serine protease expression. A mRNA expression of total ACE2. B mRNA expression of long form ACE2. C mRNA expression of short form ACE2. D mRNA expression of TMPRSS2. E mRNA expression of TMPRSS4. Ctrl, control; CSM, cigarette smoke medium; SCoV2, SARS-CoV-2; H, hours. MOI of 2 was used for analysis of gene expression. Values are expressed as mean ± SEM (n = 5). *p < 0.05, **p < 0.01 for One-way ANOVA test with post hoc analysis and Tukey correction
