Therefore, we analysed the correlation between the expression of NIPBL and RUNX1 in BM cells derived from 20 patients NPMc+, selected among the 34 AML patients, compared to 14 patients NPM1wt and found a significant positive correlation in NPMc+ but not in NPM1wt AML patients (Figure 1E‐F). This evidence concerns the gene NIPBL and acute myeloid leukemia.
