By rank-ordering of enhancer regions based on H3K27ac enrichment, we discovered that T-cell acute lymphoblastic leukemia (T-ALL (RPMI18402, Jurkat and MOLT3)) diffuse large B-cell lymphoma (DLBCL (LY4)) and breast cancer (MCF7 and HCC1954) cell lines have SEs within ∼200 kb of CD47 (Fig. 1a). The gene discussed is CD47; the disease is breast carcinoma.
