We next compared the MBD2 binding peaks near TSSs ( ± 5000 bp) in a publicly available ChIP-Atlas dataset42 obtained from human MCF-7 breast cancer cells stably transfected with MBD2 (NCBI GEO accession no. SRX471210) with the peaks identified near TSSs in our ChIP-Seq data from primary mouse breast tumors and found 10 overlapping genes (Fig. 4g). This evidence concerns the gene MBD2 and breast carcinoma.
