Unraveling the Blockade: How Mutant IDH1 Impairs Neutrophil Differentiation in Preleukemic Hematopoiesis
Highlight
- Mutant IDH1 causes lineage-specific epigenetic alterations selectively impairing neutrophil differentiation in acute myeloid leukemia (AML).
- IDH1 is physiologically upregulated in myeloid progenitors, linking its mutation to targeted repression of neutrophil transcriptional programs.
- A heterozygous inducible Idh1 mutant mouse model demonstrated a cell-intrinsic block in neutrophil differentiation by suppressing key transcription factors, including Cebpe.
- Reactivation of differentiation by Cebpe induction or hypomethylating agents reveals the differentiation block is reversible, offering therapeutic avenues for IDH1-mutant myeloid neoplasms.
