Additional file 1 shows the differentially expressed genes in the vicinity of ER binding sites. Using 3 gene expression studies and a criterion of q-value <0.01, we identified 5692 and 6101 up- and down-regulated down-regulated genes between ER+ and ER- breast tumors. Among these genes, 289 up-regulated and 198 down-regulated genes located near the ER binding sites. The details of these 489 estrogen response elements were listed here. Additional file 2 shows the SNPs occurred in the ER-regulated genes located near the binding sites. These SNPs were identified by using the table SNP (131) (dbSNP build 131) in UCSC ( Totally, 836 SNPs in or near 157 ER-regulated genes were identified.
