Defining the minimum number of cTFBSs required for the identification of estrogen responsive ESCC genes. This figure is a graphical representation of the proportion of genes that contain multiple cTFBSs mapped to their promoters. The graph depicts the threshold defining the maximum difference between the known estrogen responsive genes (C1 and C3) relative to the background set (C4).
