The percentage of genes whose ratio of expression in the AdNKX2-1-infected cells to that in the AdLacZ-infected cells was (A) twice or higher and (B) 0.5-fold or lower in GeneChip analyses 6, 12, and 24 h after 100 MOI adenoviral vector infection. A total of 54,613 transcripts were analyzed. Data with statistically insignificant changes were excluded from the analysis.
