ACE2 and infection: Then, to better obtain a global picture of the transcriptome landscape in response to the “early phase” of SARS-CoV-2 infection and given the importance of Ca2+ homeostasis in SARS-COV-2 infection, we employ gene expression (i.e., RNA-seq) analysis in the HEK293T-ACE2 cellular model upon infection (VOC Delta at 0.026 MOI) for 24 h (see Fig. 1E).
