HOPX and acute myeloid leukemia: We found that expressions of SPINK2, MAP7, HOPX, MMRN1, DNMT3B, TCF4, SLC38A1, DOCK1, ARHGAP22, MN1, and 4 genes in the ATP-binding cassette (ABC) superfamily (ABCG1, ABCA2, ABCB1, and ABCC1), which have been reported to be associated with poor prognosis or chemoresistance in AML, were positively correlated to higher expression of KIAA0125 (Fig. 3b and Table 3).
