TP53 and diffuse large B-cell lymphoma: Methylation of the death associated protein kinase (DAPK or DAPK1) gene and TP53 mutations are likely to have prognostic value in DLBCL, and a better understanding of the molecular pathways leading to DLBCL progression may be important for the development of novel therapies aiming at causing DLBCL cells to undergo apoptosis [2].
