摘要: Purpose To determine the ara-C-modulating efficacy of retinoids in leukemic blast cells. All-trans retinoic acid (ATRA) has been shown to increase sensitivity AML cells cytosine-arabinoside (ara-C). Ara-CTP accumulation is considered be main determinant ara-C toxicity vitro and vivo. To test hypothesis that exert their sensitizing effect by enhancing intracellular ara-CTP we studied ATRA 13-cis (13-cis RA) on ara-CTP-formation HL60 after 24 72 hours preincubation retinoid containing medium 1 hour exposure ara-C.
