Overall the report suggests that results obtained in NR4A1-knockout mice (whole body) expressing aa1-117 may need to be reinterpreted, particularly since this truncated form of NR4A1 (namely TR3β) is expressed and may be functional in some tissue/cell types, including human bone marrow cells and acute myeloid leukemia. Here, NR4A1 is linked to acute myeloid leukemia.
