CKD-581 treatment also up-regulated the phosphorylation of histone H2AX (γH2AX, DNA double-strand break marker), and reduced levels of MYC and anti-apoptotic proteins such as BCL-2, BCL-6, BCL-XL, and MCL-1 in DH/DE-diffuse large B cell lymphoma (DLBCL) cell lines. Here, MYC is linked to diffuse large B-cell lymphoma.
