Comparison of RNA levels of E2F target genes. The expression levels of the RNA of the top 2000 E2F1, E2F4, and E2F6 target genes were determined by analyzing RNA from Ntera2 cells using Illumina arrays. For comparison, the set of E2F6-specific genes was also analyzed. Values <300 are considered to represent genes that are not expressed, whereas values >300 represent expressed genes.
