Of 58 lymphoma tissues, DLEC1 methylation was detected in 5/6 (83%) BL, 16/30 (53%, one weak) HL, 1/10 (10%) DLBCL, 6/8 (75%) NL, and 4/4 (100%, two weak) follicular lymphoma (FL) tumor samples, while no methylation was detected in normal lymph node samples (Figure 4A and B; Table 1). This evidence concerns the gene DLEC1 and diffuse large B-cell lymphoma.
