Phosphatidylcholine Synthesis Declines with Age to Contribute to Mitochondrial Dysfunction
Researchers identified a conserved age‑related decline in phosphatidylcholine (PC) synthesis as a key driver of mitochondrial dysfunction. Using C. elegans, human transcriptomic and metabolomic data, they showed that reduced activity of SAMS‑1 and PEMT enzymes leads to mitochondrial fragmentation and lower respiration. Supplementation with choline or PC rescued these defects in worms, cell cultures, and aged tissues. Human GTEx and UK Biobank analyses confirmed PC and PEMT levels drop with age, particularly in post‑menopausal women.
