The A-to-I and C-to-U RNA editing levels of common editing sites of HTBE cells infected with H1N1, H3N2 and H5N1 at different time points. a The normalized A-to-I RNA editing level of HTBE cells infected with H1N1, H3N2 and H5N1 at different time points. b The normalized C-to-U RNA editing level of HTBE cells infected with H1N1, H3N2 and H5N1 at different time points. The normalized RNA editing level is achieved by dividing the original value of RNA editing level (which is defined as the proportion of edited reads among the total mapped reads at a given site) by the highest value at different time points
