As similarly demonstrated previously, KSEA of phosphoproteome data of AML-derived cells from 20 patients had similar enrichment of CSK2, CDK, PAK, AKT, ABL, SRC, MAPK, PRKA and PRKC kinases, relative to normal peripheral blood stem CD34+ cells from five healthy donors [45]. This evidence concerns the gene CD34 and acute myeloid leukemia.
