DNMT1 and breast cancer: Furthermore, by analyzing Oncomine data derived from Brune et al., [24] we determined that human Burkitt’s lymphoma (BL) specimens significantly overexpress DNMT1 (1.44-fold, P=0.032) and DNMT3B (1.46-fold, P=4.71×10-4) when compared to non-malignant B-cells (BC) obtained from healthy donors (Figure 2B).
