Wee1 is found to be overexpressed in hematological tumors such as acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic myeloid leukemia (CML), chronic lymphocyte leukemia (CLL), multiple myeloma (MM), and diffuse large B cell lymphoma (DLBCL) [179,182,183,184,185]. This evidence concerns the gene WEE1 and acute lymphoblastic leukemia.
