RCN1 and acute myeloid leukemia: To investigate the role of RCN1 in AML cells, we utilized clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR‐associated protein 9 (Cas9) technology to establish three RCN1 gene knockout cell clones (MOLM‐13‐23, MOLM‐13‐240, and MOLM‐13‐242) derived from the human AML cell line MOLM‐13.
