Arsenic trioxide (As_2O_3) effectively induces clinical remission via apoptosis in related acute promyelocytic leukemia (APL). However, because this new anti-leukemic drug is also considered to be a poison, its possible adverse effects are a highly important issue related to its clinical use. We investigated both in vitro and in vivo, the effects of a combination of As_2O_3 and GM-CSF as a novel therapeutic approach for the treatment of acute leukemia. Treatment of acute lmyeloid eukemic cells with a combination of As_2O_3 and GM-CSF for 4 days resulted in differentiation, but not apoptosis, to mature granulocytes. GM-CSF was found to be associated with increased tyrosine phosphorylation of Jak2 kinase in acute promyelocytic leukemia (APL) cells, and a specific inhibitor of Jak2, AG490, completely blocked the ability of GM-CSF to prevent apoptosis and induce differentiation of As_2O_3-treated APL cells. In in vivo analysis, As_2O_3 induced differentiation of APL cells in a retinoic aci … More d-resistant APL model of human GM-CSF-producing transgenic SCID mice that had a high level of human GM-CSF in their sera. In contrast, As_2O_3 alone diminished tumors in retinoic acid-resistant APL UF-1 cells transplanted into NOD/SCID mice via induction of apoptosis.We also performed the experiments using TGF-β superfamily cytokines including bone morphogenetic protein(BMP) and activin A for inducing apoptosis of leukemia and myeloma cells. BMP induces apoptosis of human myeloma cell lines and primary samples. BMP caused cell cycle arrest in the G1 phase which was associated with accumulation of p21 and p27, and the subsequent apoptosis of myeloma cells. BMP also induced down-regulation of Bcl-X_L through the inactivation of STAT3, resulting in the induction of apoptosis of myeloma cells. In addition, activin A induced rapid apoptosis of chronic myeloid leukemia (CML) cells via transient induction of Mcl-1. These results suggest that cytokines may have a potential to be novel therapeutic agents for treatment in patients with leukemia and myeloma. Especially, a combination of As_2O_3 and GM-CSF appears to be a novel differentiation-inducing therapy for APL with less toxic effects. Less

三氧化二砷（As_2O_3）通过诱导凋亡有效地诱导相关急性早幼粒细胞白血病（APL）的临床缓解。然而，由于这种新的抗白血病药物也被认为是一种毒药，其可能的不良反应是与其临床使用相关的一个非常重要的问题。我们研究了As_2O_3与GM-CSF联合应用治疗急性白血病的体内外效应。用As_2O_3和GM-CSF联合处理急性髓系白血病细胞4天，导致向成熟粒细胞分化，但不导致凋亡。GM-CSF与急性早幼粒细胞白血病（APL）细胞中Jak 2激酶的酪氨酸磷酸化有关，而Jak 2的特异性抑制剂AG 490可完全阻断GM-CSF对As_2O_3处理的APL细胞的抗凋亡和诱导分化作用。在体内分析中，As_2O_3诱导APL细胞在视黄酸溶液中分化， ...更多信息 产生人GM-CSF的转基因SCID小鼠的d-抗性APL模型，其在其血清中具有高水平的人GM-CSF。另外，我们还用TGF-β超家族细胞因子骨形态发生蛋白（BMP）和激活素A（activin A）诱导白血病和骨髓瘤细胞凋亡。BMP诱导人骨髓瘤细胞系和原代样品的凋亡。BMP使骨髓瘤细胞周期阻滞在G1期，这与p21和p27的积累以及随后的骨髓瘤细胞凋亡有关。BMP还通过STAT 3的失活诱导Bcl-X_L的下调，导致诱导骨髓瘤细胞的凋亡。此外，激活素A通过瞬时诱导Mcl-1诱导慢性粒细胞白血病（CML）细胞的快速凋亡。这些结果表明，细胞因子可能有潜力成为治疗白血病和骨髓瘤患者的新型治疗药物。特别是As_2O_3与GM-CSF的联合应用，可能是一种毒副作用小的诱导分化治疗APL的新方法。少
