The enriched pathways included: neuregulin signaling, PTEN signaling, PI3K/AKT signaling, erythropoietin signaling, regulation of EIF4 and p706SK signaling, chronic myeloid leukemia signaling, tight junction signaling, telomerase signaling, aryl hydrocarbon receptor signaling, Rac signaling, molecular mechanisms of cancer, prolactin signaling NGF signaling, and FLT3 signaling in hematopoietic progenitor cells. This evidence concerns the gene EPO and chronic myelogenous leukemia, BCR-ABL1 positive.
