GATA1 and myelodysplastic syndrome: Gata1 mRNA expression is increased in sorted bone marrow ProE (A), unchanged in BasoE (B), and significantly decreased in PolyE (C) erythroblasts from MDS relative to WT mice; DFP treatment restores Gata1 mRNA expression relative to untreated MDS or WT mice in all including OrthoE (D) erythroblasts (n=15–21 mice/group).
