miR-9 restrain the sharp increase of AML cells and boost their apoptosis. After transfection of miR-9 mimic, NC mimic, miR-9 inhibitor and NC inhibitor, QRT-PCR was used to find out the expression of miR-9; (b) after transfection of miR-9 mimic, NC mimic, miR-9 inhibitor and NC inhibitor, CCK-8 was used to detect the cell viability of HL-60. (c) After transfection of miR-9 mimic, the abrupt increase of HL-60 cells was detected by cell colony assay, NC mimic, miR-9 inhibitor and NC inhibitor; (d) After transfection of miR-9 mimic, NC mimic, miR-9 inhibitor and NC inhibitor, flow cytometry was used to detect the apoptosis rate of HL-60. Compared with NC inhibitor, **P < 0.01; compared with NC mimic, ^##P < 0.01
