Understanding Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is characterized by a complex interplay of genetic mutations that disrupt normal cell differentiation and growth. Among the most significant mutations are those in genes related to growth factor receptors, particularly FLT3, which is found mutated in approximately 25% of AML cases. The research indicates that these mutations lead to a reorganization of gene regulatory networks (GRNs), which impacts hematopoietic stem and progenitor cell identities. This alteration not only impedes typical myeloid differentiation but also presents a significant challenge in treating AML effectively.
