What molecular mechanism causes VCP mutations to trigger aberrant HIF-1α activation under normoxic conditions?

PARTIALLY ADDRESSED

The study shows VCP-mutant astrocytes exhibit hypoxia response activation without actual hypoxia, but the mechanistic link between VCP dysfunction and HIF-1α stabilization remains unexplained. Understanding this connection is critical for developing targeted therapies that could prevent early pathogenic events in VCP-ALS. Gap type: unexplained_observation Source paper: Hypoxic stress is an early pathogenic event in human VCP-mutant ALS astrocytes. (2026, Stem cell reports, PMID:41349534)
