Abstract
Synthesis of the biologically active metabolite(s) from 1α‐hydroxyvitamin D3 (1α(OH)D3) was examined in various types of human leukemia cell lines. Untreated monocytoid leukemia cells (U937 and HE/S) metabolized 1α(OH)D3 to the active metabolite(s), possibly 1α,24‐ and/or 1α, 25‐dihydroxyvitamin D3, and these cells were efficiently induced to differentiate by treatment with 1α(OH)D3. However, the other types of leukemia cells did not efficiently metabolize it and were not induced to differentiate by 1α(OH)D3. The possible therapeutic advantage of 1α(OH)D3 in the treatment of monocytic leukemia is discussed.Keywords
