ABSTRACT
BACKGROUND:
Recent years, survival rates of human with high-risk acute myeloid leukaemia (AML) have not raised substantially. This research aimed to investigate the role of 4'-O-Methylbroussochalcone B, for the treatment of human AML.METHODS:
Firstly, we evaluated the effects of six chalcones on AML cells activity by MTT assay. Immunofluorescence staining, tubulin polymerization assay and N,N'-ethylenebis (iodoacetamide) (EBI) competition assay were performed on ML-2 cells. Transwell and apoptosis assay were also utilized in ML-2 cells and OCI-AML5 cells. The expressions of migration-related proteins, apoptosis-related proteins and Wnt/ß-catenin pathway were detected by Western Blot.RESULTS:
The results found six chalcones exhibited the anti-proliferative activity against different AML cell lines. Based on the results of immunofluorescence staining, tubulin polymerization assay and EBI competition assay, 4'-O-Methylbroussochalcone B was discovered to be a novel colchicine site tubulin polymerization inhibitor. 4'-O-Methylbroussochalcone B could induce apoptosis, inhibit proliferation and migration of ML-2 cells and OCI-AML5 cells. The cells were arrested in the G2-M phase by the treatment of 4'-O-Methylbroussochalcone B. In addition, 4'-O-Methylbroussochalcone B regulated MAPK and Wnt/ß-catenin pathways in AML cells.CONCLUSION:
4'-O-Methylbroussochalcone B might inhibit proliferation and migration of the AML cells by MAPK and Wnt/ß-catenin pathways as a tubulin polymerization inhibitor. It is promising for 4'-O-Methylbroussochalcone B to become a new drug to treat AML.Palavras-chave
