After PMA treatment, 136 genes were up-regulated and 61 down-regulated. Of these, 24 and 8, respectively, were found to be EGR-1 target genes. Percentage values indicate the number of target genes with bound promoters whose expression was up- or down-regulated at the indicated time point out of all EGR-1 target genes up- or down-regulated, respectively, over the entire time course (0-6 hours).
