Vitamin D deficiency has been linked with increased cancer risk, and vitamin D has been shown to be cytotoxic to some cancer cells in vitro. In the present study we evaluated whether vitamin D would have antiproliferative or cytotoxic effects on human pre-B acute lymphoblastic leukemia cells. Contrary to our hypotheses, calcitriol, the active form of vitamin D, had no effect on leukemia cell proliferation. Calcitriol actually had a modest effect to impair dexamethasone cytotoxicity and induction of apoptosis. Further studies are needed to evaluate the effects of vitamin D on leukemia cells in vivo.
