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.
