Synthesis pass · prose summary of the discoveries below

ELANE encodes neutrophil elastase (NE), a serine protease stored in primary granules that functions in innate immune defense, chromatin remodeling during myeloid differentiation, and regulation of cell death pathways. Transcription of ELANE is activated by LEF-1 and C/EBPα and repressed by GFI1 and miR-608, and its expression is tightly coupled to myeloid lineage commitment (PMID:12778173, PMID:19620402, PMID:31749032). Dominant heterozygous ELANE mutations cause cyclic neutropenia and severe congenital neutropenia through NE protein misfolding, mislocalization away from primary granules, ER stress/UPR activation, and promyelocyte death, with NMD-escaping truncated isoforms being the pathogenic species (PMID:10581030, PMID:21285438, PMID:26193632, PMID:33513358). Beyond granulopoiesis, NE catalyzes amino-terminal cleavage of histone H3 to regulate chromatin accessibility during monocyte-to-macrophage differentiation and promotes hepatocyte ferroptosis by stabilizing KEAP1 to suppress the NRF2–GPX4 antioxidant axis (PMID:34017121, PMID:40204709).

  3. 2003 High

    Two independent studies defined the transcriptional circuitry controlling ELANE: GFI1 was shown to directly repress ELANE (with GFI1 loss-of-function mutations causing neutropenia via de-repression), while LEF-1 and CBFα/RUNX1 were shown to co-activate the ELANE promoter, with SCN-associated promoter mutations disrupting LEF-1 binding.

    A transgenic mouse model with the G193X Elane mutation provided in vivo proof that UPR/ER stress drives neutropenia: granulocytic precursors were selectively vulnerable to ER stress, and proteasome inhibition blocking ERAD caused marked neutropenia, while Perk knockout provided genetic epistasis.

    Evidence SCN patient iPSC genome editing/differentiation, NE localization imaging, UPR assays, sivelestat treatment

    PMID:26193632

  11. 2021 High

    Three 2021 studies resolved distinct questions: (1) a CRISPR screen in HSPCs demonstrated that NMD-escaping late-exon frameshifts are the pathogenic ELANE alleles, while early-exon NMD-triggering frameshifts support normal neutrophil maturation; (2) NE was shown to catalyze histone H3 amino-terminal cleavage in monocytes, regulating chromatin accessibility during differentiation; (3) ELANE-mutant iPSC progenitors displayed elevated ROS and PML nuclear bodies in a feed-forward loop with ELANE expression.

    • Whether the NMD-escape model fully explains all SCN-causing ELANE missense mutations
  12. 2025 Medium

    A non-hematopoietic role for NE was established: ELANE promotes hepatocyte ferroptosis in metabolic liver disease by disrupting the P62–KEAP1 interaction, stabilizing KEAP1, enhancing NRF2 ubiquitination and degradation, and reducing GPX4-mediated antioxidant defense.

    Evidence Elane-KO mice on HFD, primary hepatocyte MAFLD model, recombinant ELANE treatment, Co-IP for ELANE/KEAP1/P62 interactions, ubiquitination assays
