The microarrays are identified by their GEO data set accession number. Indicates modified in the microarrays, Indicates not-modified. Complete consensus list of up-regulated genes in the preeclamptic placenta is provided as . In addition, an alternative regulatory module of two elements was found present 21505263 in the promoter of six out of the seven TFs consistently up-regulated in the preeclamptic placenta. In the case of the consistently down-regulated TFs we found one highly significant model composed of six elements corresponding to TFBS for E2FF, RXRF, KLFS and ZF02. This module was present in the promoter of three out of four genes.
