    DGUOK deficiency is linked to mitochondrial DNA depletion syndromes, causing hepatic steatosis and inflammation despite preserved mtDNA content.

  • 2

    Acute DGUOK depletion in HepG2 cells leads to increased lipid droplet accumulation and activation of type I interferon signaling.

  • 3

    Bulk RNA sequencing reveals induction of human endogenous retroviruses and interferon-stimulated genes alongside suppression of lipid metabolic pathways.

  • 4

    DGUOK-deficient cells show a significant reduction in global DNA methylation, affecting specific interferon-stimulated gene promoters.

  • 5

    The study suggests that DGUOK deficiency disrupts purine metabolism, linking innate immune activation to lipid accumulation in liver cells.
