Aged human muscle secretes an enzyme that impairs stem cell maintenance
Profiling conditioned media revealed that altered sphingolipid signaling reduces muscle stem cell pools in human cell cultures.
Suppressing neuronal dENL/AF9 shifts metabolic and energetic profiles in aged flies
Multi-omics profiling in Drosophila links chromatin regulation to increased ATP, higher NAD-to-NADH ratios, and altered lipid metabolism in aged heads.
Disrupted sphingolipid metabolism drives lysosomal and mitochondrial failure in Parkinson's disease
A preprint shows SMPD1 upregulation collapses a sphingolipid salvage pathway, causing mitophagy defects and marking aggressive motor phenotypes.
