The complete results of data-mining are presented in Additional files 7 and 8. aStatistical significance of gene enrichment was computed using algorithms implemented in DAVID 2008 database and ErmineJ software. bConserved promoter regions +5,000/-1,000 bp from the transcription start site were analyzed (see Materials and methods). cFold change of the detected number of identified transcription factor binding sites (TFBSs) compared to the number expected by chance. dStatistical significance of over-representation of TFBS-containing genes compared to a number expected by chance was computed using a z-score test.
