Abstract

The antitumor enzyme L‑asparaginase (L‑Asp) has commonly been used for the treatment of acute lymphoblastic leukemia. However, the effects of L‑Asp on acute myeloid leukemia (AML) and their underlying mechanisms have not been fully elucidated. In the present study, the effects of L‑Asp on cell proliferation and apoptosis were investigated using the AML cell lines U937, HL‑60 and KG‑1a. The effects of combining L‑Asp with mitoxantrone (MIT) and cytarabine (Ara‑c) were also analyzed. The combination of MIT and Ara‑C is known as MA therapy, and is a widely used therapeutic regimen for the treatment of elderly patients with refractory AML. When applied alone, L‑Asp inhibited cell proliferation and induced apoptosis in each of the cell lines tested. Furthermore, the combined use of L‑Asp with MA therapy further potentiated the inhibition of cell proliferation while increasing the induction of apoptosis. These findings provide evidence for the potential antitumor effect of L‑Asp in AML, and indicate that improved efficacy maybe achieved by combining L‑Asp with MIT and Ara‑c. This combination may provide a promising new therapeutic strategy for the treatment of AML.
