Phosphatidylcholine-Plasmalogen-Oleic Acid Reduces BACE1 Expression in Human SH-SY5Y Cells
BIOLOGICAL & PHARMACEUTICAL BULLETIN(2024)
摘要
Plasmalogens are a family of glycerophospholipids containing one vinyl-ether bond at the sn-1 position in the glycerol backbone, and play important roles in cellular homeostasis including neural transmission. Therefore, reductions of plasmalogens have been associated with neurodegenerative disorders, such as Alzheimer's disease (AD). To evaluate the potential protective effects of plasmalogens against the pathology of AD, protein expression levels of key factors in amyloid precursor protein (APP) metabolic processes were examined using human neuroblastoma SH-SY5Y cells. Here, phosphatidylcholine-plasmalogen-oleic acid (PC-PLS-18) was shown to reduce protein expression levels of fl-site APP cleaving enzyme 1 (BACE1), clusterin, and Tau, factors involved in the amyloid fl-associated pathogenesis of AD. Thus, PC-PLS-18 may have preventive effects against AD by delaying the onset risk for a certain period. Key words plasmalogen, fi-site amyloid precursor protein cleaving enzyme 1, Tau
