Given that FOXO4 and FOXP3 were highly expressed in combination in precursor T lymphoblastic leukemia, acute promyelocytic leukemia, leukemia, and acute myeloid leukemia, we explored the correlation of these two genes in the GEPIA2 database and found that they were positively correlated in AML (Figure 1C). Here, FOXP3 is linked to leukemia.
