| الوصف: | Background : Acute myeloid leukemia (AML) is regarded as a haematological malignancy and seriously threatens the public’s health. Circular RNA (circRNA) is gradually confirmed to be involved in the development of AML. The purpose of this study was to disclose the role of circRNA Potassium Voltage-Gated Channel Subfamily Q Member 5 (circ_KCNQ5) in AML.Methods : Quantitative real-time PCR (qPCR) and western blot were used for expression analysis. Colony formation assay, EdU assay and MTT assay were performed to determine cell proliferation. Flow cytometry assay was conducted to determine cell apoptosis. The predicted binding relationship between miR-622 and circ_KCNQ5 or RAS oncogene family member 10 (RAB10) was verified by dual-luciferase reporter assay.Results : The expression of circ_KCNQ5 was increased in bone marrow samples of childhood AML patients and AML cell lines. The knockdown of circ_KCNQ5 largely suppressed AML cell proliferation and promoted cell apoptosis. Circ_KCNQ5 directly bound to miR-622 and inhibited miR-622 expression. The cotransfection of miR-622 inhibitor reversed the effects of circ_KCNQ5 knockdown and thus recovered cell proliferation and depleted cell apoptosis. RAB10 was a target of miR-622, and circ_KCNQ5 bound to miR-622 to increase the expression of RAB10. MiR-622 restoration inhibited AML cell proliferation and induced cell apoptosis, while RAB10 overexpression abolished these effects.Conclusion : Circ_KCNQ5 high expression was associated with childhood AML malignant development, and circ_KCNQ5 participated in AML progression by regulating the miR-622/RAB10 pathway. |
