Figure Lengend Snippet: SARS-CoV-2 Nsp9 Western blot analysis. A) SARS-CoV-2 Orf6, Orf3a, and Nsp9 expression. A549 cells were reverse transfected with 2 μg Orf6, Orf3a, or Nsp9 expression vectors and then lysed for protein detection by Western blotting. B) Western blotting of p-NF-kB, NF-kB, and TBK1 protein expression in 24 h poly I:C-treated A549 cells transfected with Nsp9 or empty vector control plasmids. B-tubulin is used as a control for protein expression. C) Densitometry analysis showing relative TBK1 abundance in 24 h poly I:C (PIC)-treated A549 cells transfected with Nsp9 or empty vector control plasmids compared to nontransfected and nontreated A549 cells ( n = 3). Error bars represent standard error of the mean, * = p < 0.05.
