To further verify the correlation between PML‐RARα and LMO2 in a large population, we retrieved three data sets (TCGA, GSE10358 and GSE1159) on the expression profiling of 743 AML patients,20, 21, 22 including 76 APL patients and 667 patients with other AML subtypes. Here, LMO2 is linked to acute myeloid leukemia.
