Suppression of Lipid Accumulation in 3T3-L1 Adipocytes by α-Tocopheryl Succinate.

In this study, we found for the first time that TS significantly suppressed lipid accumulation in mouse 3T3-L1 adipocytes. TS treatment reduced the amount of triglycerides in the culture medium, and inhibited activity of glycerol-3-phosphate dehydrogenase, a marker of lipid synthesis. Furthermore, TS accelerated lipolysis. Treatment of adipocytes with TS for 24 h induced no significant cytotoxicity. In TS-treated cells, phosphorylation of Akt, which is involved in fatty acid synthesis via sterol regulatory element-binding proteins (SREBP), was prevented, while levels of phosphorylated protein kinase A (PKA) did not change. Taken together, these results suggest that vitamin E ester TS can suppress lipid accumulation in adipocytes by regulating lipid metabolic cell signaling. PMID: 33390549 [PubMed - in process]
