The results showed that infection of NHBE and Calu-3 cells with SARS-CoV-2 did not impact mRNA expression levels of AGO2, DICER1, DGCR8, DROSHA, and XPO5 at 24 and 48 h post infection (Figure 2 and Figure 3), in good concordance with our results on patient samples. The gene discussed is DICER1; the disease is infection.
