Fold change. The intensity ratio of probe signal criteria for differential expressions was defined as a twofold change (up or down) (log2 FC ≥ 1 or ≤−1) in gene expression compared with virus control group and a value less than 0.05 in at least one time point as a minimum requirement to select. For instance, log2 (M/N) ≥ 1 means that the comparison between normal control group and virus control group was scattered, indicating that a large number of genes in virus control group were up-regulated in response to H1N1 infection. log2 (SH/M) ≤−1, log2 (SM/M) ≤ −1, log2 (SL/M) ≤ −1, and log2 (Oseltamivir/M) ≤ −1 means that down-regulation in gene expression attributable to the high-dose SFXF group treatment, medium-dose group SFXF treatment, low-dose SFXF group treatment, and Oseltamivir group treatment was done by comparing genes in virus control group, respectively ( value data not shown).
