Epigenetic therapy as a novel approach for GFI136N-associated murine/human AML.

Epigenetic changes can contribute to development of acute myeloid leukemia (AML), a malignant disease of the bone marrow. A single-nucleotide polymorphism of transcription factor growth factor independence 1 (GFI1) generates a protein with an asparagine at position 36 (GFI1(36N)) instead of a serine at position 36 (GFI1(36S)), which is associated with de novo AML in humans. However, how GFI1(36N) predisposes to AML is poorly understood.

GFI1(36N) as a therapeutic and prognostic marker for myelodysplastic syndrome.

Inherited gene variants play an important role in malignant diseases. The transcriptional repressor growth factor independence 1 (GFI1) regulates hematopoietic stem cell (HSC) self-renewal and differentiation. A single-nucleotide polymorphism of GFI1 (rs34631763) generates a protein with an asparagine (N) instead of a serine (S) at position 36 (GFI1(36N)) and has a prevalence of 3%-5% among Caucasians.
