To explore the link between TET2 mutations and MIF expression in human primary samples, we sorted peripheral blood monocytes from 60 CMML patients (17 TET2-wild-type [TET2WT] and 43 TET2-mutated [TET2MUT] cases) (Supplementary Table 1) and from 10 age-matched healthy donors and performed bulk RNA sequencing. The gene discussed is TET2; the disease is chronic myelomonocytic leukemia.
