We were, however, not able to study these possibilities as none of the DLBCL cell lines we have screened for allelic DAPK1 methylation patterns carried monoallelic methylation [13], but we observed that DAPK1 was expressed at similar levels in samples from patients with monoallelic methylation and patients with biallelic methylation. Here, DAPK1 is linked to diffuse large B-cell lymphoma.
