摘要: The outcome of acute myelogenous leukemia (AML) therapy depends on the propensity leukemic blasts to accumulate ara-CTP, active triphosphate cytarabine (ara-C). We identified sterile α motif and HD domain-containing protein 1 (SAMHD1) as an ara-CTPase that protects cancer cells from cytarabine-induced toxicity. Therefore, we propose targeting SAMHD1 a strategy potentiate possibly other antimetabolite-based therapies.
