We compared the expression levels of CNST in the leukemia cell lines Kasumi-1 and KO-52, where the Kasumi-1 cell line expresses RUNX1–RUNX1T1 and the KO-52 does not, and the results showed that the expression of CNST was higher in Kasumi-1 (Student’s t-test, p < 0.001; Figures 2E,F). The gene discussed is CNST; the disease is leukemia.
