摘要
Objectives This study aimed to investigate the efficacy of boanmycin, a clinical drug used for head and neck cancers, in the treatment of acute myeloid leukemia (AML), particularly in venetoclax-resistant AML cells.Methods The cell viability assay was conducted to measure the inhibitory effects of boanmycin on the AML cell lines and patient primary cells using the CCK8 reagent. The colony formation assay was performed to evaluate the colony formation ability of HL60 and venetoclax-resistant HL60 (HL60-res) cells with or without boanmycin treatment. Flow cytometry was performed to detect cell apoptosis level, and Western blot was used to assess changes in apoptosis-related proteins.Results Our findings reveal that boanmycin significantly inhibits AML cell proliferation and colony formation, and induces apoptosis. Importantly, boanmycin exhibits substantial inhibitory effects on venetoclax-resistant cells, and suppresses the proliferation of peripheral blood mononuclear cells (PBMCs) or bone marrow mononuclear cells (BMMCs) derived from newly diagnosed and relapsed AML patients.Conclusions Boanmycin may overcome venetoclax resistance and offer therapeutic benefits for patients with venetoclax-resistant AML.
