Researchers used various sequencing technologies to explore the molecular characteristics of myeloid/natural killer cell precursor acute leukemia (MNKPL). They observed activation of the NOTCH1 and RUNX3 genes, with lower expression of the BCL11B gene. MNKPL cells were also highly sensitive to a drug called L-asparaginase. Collectively, these qualities make MNKPL distinct from other leukemia types. These insights will assist with more accurate clinical diagnoses and therapeutic development for MNKPL.
