We queried the comparative toxicogenomics database (CTD) to identify studies reporting changes in expression levels of human genes encoding receptor and proteases J o u r n a l P r e -p r o o f important for SARS-CoV-2 cell entry upon chemical exposure (Davis et al., 2019) . Using these criteria, we identified several chemical exposures regulating the expression of receptor ACE2 and human proteases TMPRSS2, FURIN and Cathepsins genes in human cells and tissues (Figure 2; Supplementary Table S2 ). Our analysis suggests that expression of human receptor and proteases of SARS-CoV-2 spike S glycoprotein are not directly regulated by cigarette smoke at the transcriptional level in lung cells, nor that PIR and ACE2 are coregulated upon cigarette smoke exposure. ./cache/cord-282133-5dzzm9s8.txt ./txt/cord-282133-5dzzm9s8.txt
