To validate the ability of miR-7-5p to inhibit the cellularproliferative activity of AML by targeting OSBPL11through the PI3K/AKT/mTOR signaling pathway, we transfected HL-60 and MOLM13 cellswith OSBPL11 vector and evaluated its effects onproliferation and apoptosis. The gene discussed is OSBPL11; the disease is acute myeloid leukemia.
