There are few studies on the correlation between heme oxygenase-1 (HO-1) and acute myeloid leukemia (AML). We found that HO-1 was aberrantly overexpressed in the majority of AML patients, especially in patients with acute monocytic leukemia (M5) and leukocytosis, and inhibited the apoptosis of HL-60 and U937 cells. Moreover, silencing HO-1 prolonged the survival of xenograft mouse models. Further studies demonstrated that HO-1 suppressed the apoptosis of AML cells through activating the JNK/c-JUN signaling pathway. These data indicate a molecular role of HO-1 in inhibiting cell apoptosis, allowing it to be a potential target for treating AML.
关于血红素加氧酶-1(HO-1)与急性髓系白血病(AML)之间相关性的研究较少。我们发现,HO-1在大多数AML患者中异常高表达,尤其是急性单核细胞白血病(M5)和白细胞增多症患者,并抑制HL-60和U937细胞的凋亡。此外,沉默HO-1可延长异种移植小鼠模型的生存期。进一步研究表明,HO-1通过激活JNK/c-JUN信号通路抑制AML细胞的凋亡。这些数据表明HO-1在抑制细胞凋亡中具有分子作用,使其成为治疗AML的潜在靶点。
