TABLE 8 Transcription factor binding sites common to all conditions
p values for transcription factor binding sites that were found to be over-represented in all four of the effects studied. Here, AHR(↓) refers to genes with negative AHR effects, whereas AHR-TCDD(↑) refers to genes with positive interactions. The ID number refers to the JASPAR identifier of the matrix used for testing the specific TFBSs. The p values given here were obtained by dinucleotide randomization studies (1000 iterations). Of the 15 TFBSs here, only five are under-represented (MA0054, MA0103, MA0036, and MA0024), whereas 10 are over-represented. Many of these TFBSs are likely to be liver-specific rather than AHR-specific.
