Calcitriol (1,25-dihydroxyvitamin D3, 1,25D3) and vitamin D side-chain modified analogs (VDAs) have gained considerable attention as potential drugs in the treatment of acute myeloid leukemia (AML), yet studies of the impact of 1,25D3 and VDAs upon other haematological malignancies are more limited. To address this gap in knowledge, we have examined the action of 1,25D3 and VDAs on a human cell line (DOHH2, K422) typifying diffuse large B-cell lymphoma (DLBCL) and also peripheral blood B-cells isolated from healthy donors. 1,25D3 and certain VDAs displayed moderate cytotoxic and pro-apoptotic actions upon DLBCL cells. 1,25D3 and VDAs (100nM) caused the death of approximately 40% DOHH2 cells ..
