ARHGEF10L and acute myeloid leukemia: Via real‐time quantitative PCR to detect circFN1, miR‐1294, ARHGEF10L expressions in clinical plasma samples and AML cell lines, AML cells were cultured in vitro and transfected with si‐circFN1, pcDNA3.1‐circFN1, and si‐ARHGEF10L, respectively, or co‐transfected pcDNA3.1‐circFN1 + miR‐1294 mimic and pcDNA3.1‐circFN1 + si‐ARHGEF10L.
