Our study was essential for: 1) identifying functional TFAP2A binding sites in novel TFAP2A-regulated genes; 2) defining "Cellular Movement" and "Cellular Development" as the main networks in which the TFAP2A target genes are involved; 3) associate SP1 to TFAP2A gene transcription activation but not repression; 4) dissecting the TFAP2A-driven regulation of DCBLD2/ESDN, an important player of tumor progression. This evidence concerns the gene SP1 and neoplasm.
