Further, in opposite manner, in an overexpressing status of ATP2B1 upon infection of SARS-CoV-2 (VOC: Omicron, 0.03 MOI) and measuring the expression level of viral structural genes (ORF1a/b and E) and ATP2B1, we saw the reduction of viral gene expression, as featuring the impairment of viral replication (see Fig. 2G). This evidence concerns the gene ATP2B1 and infection.
