| Abstract: | Acute myeloid leukemia (AML) is a malignant clonal hematopoietic disease, which is caused by hematopoietic stem cell abnormalities. Epigenetic regulation, especially of microRNAs (miRNAs), mostly results from external or environmental effects and is critical to AML. In this study, for the first time, we report that decreased expression of miR-345-5p facilitates the proliferation of leukemia cells in AML. Further study demonstrated that AKT1/2 was the target of miR-345-5p and was responsible for the dysregulation of leukemia cell proliferation and apoptosis. Inhibition of AKT1/2 ameliorated this malignant effect, which provides new insight into AML diagnosis, treatment, prognosis, and next-step translational investigations. |
