Figure 9

H5N1 IAV upregulates the mRNA expression of Toll-like receptor 3 (TLR3), cytolytic RNA helicases retinoic acid-inducible gene I (RIG-I), and melanoma differentiation-associated gene 5 (MDA-5). (A) PAN02 and (B) PANC-1 cells were treated or infected as described in Figure 5 and harvested at 6, 12, and 24 h post-infection. Total RNA was isolated at the designated times and examined by RT-qPCR. The mRNA expression of TLR3, RIG-I, and MDA-5 is shown. The data are presented as the relative fold change over mock treatment. Graphs shown are the mean ± standard deviation (SD) of three independent replicates. Asterisks indicate statistically significant increases compared with mock-treated cells (*P < 0.05, **P < 0.01, and ***P < 0.001).
