Conclusions We have identified two set of genes whose expression altered by SARS-CoV-2 in vivo (mouse) and in vitro (human cell lines), respectively. Two gene sets are coincident with known SARS-CoV protein interacting human proteins and genes whose expression is altered by SARS-CoV infection. Drug repositioning, including ivermectin, are performed with identifying drugs that affect two set of genes. Validations: Coincidence with gold standard SARS-CoV-2 PPI and drug repositioning proposed for SARS-CoV-2. Our strategy might be promising.
