Cellular toxicity of SARS-CoV-2 genes. HEK 293 T cells were transfected with 150 ng of plasmid for each SARS-CoV-2 gene, and cell viability was analyzed by a luminescent cell viability assay. Red color indicates statistically significant cell death induced by viral gene expression (mean ± SD; n = 3 independent experimental replicates; T-test with Bonferroni correction between the control and viral gene expressing cells; *P < 0.05, **P < 0.01, ***P < 0.001; ns non-significant)
