AKT3 and acute myeloid leukemia: Gene expression profiling has revealed that transcriptional overexpression of glioma‐associated oncogene 1 (GLI1), a vital gene in the Hedgehog (Hh) signaling pathway, occurs in poor-prognosis AML, and high levels of phosphoinositide-3-kinase, regulatory subunit 1 (PIK3R1) and AKT3 predict shorter overall survival in AML patients.
