ANGPTL4 acts as a key node linking lipid metabolism and inflammation by affecting critical enzymes, regulatory factors, and receptors of lipid oxidation, synthesis, and peroxidation.
BACKGROUND: Angiopoietin-like 4 (ANGPTL4) belongs to the family of angiopoietin- like proteins. The involvement of ANGPTL4 in various aspects of lipid metabolism and inflammation has become an important area of research. METHODS: A thorough search on PubMed related to ANGPTL4, lipid metabolism, and inflammation was performed. RESULTS: Over the past two decades, the recognition of ANGPTL4 as a potent regulator of lipid metabolism has substantially increased. As part of the senescence-associated secretory phenotype, ANGPTL4 also serves as an inflammatory mediator. Considering the advancements in ANGPTL4 research, we have highlighted that ANGPTL4 acts as a key node linking lipid metabolism and inflammation. ANGPTL4 impacts inflammation by regulating lipid metabolism. It affects critical enzymes (lipoprotein lipase, hepatic lipase, endothelial lipase, and acetyl-CoA carboxylase), regulatory factors (AMPK, cAMP, SLC7A11, GPX4, and mTOR), and receptors (LepR, CD36, and PPARγ) of lipid oxidation, synthesis, and peroxidation, thereby affecting immune cells and inflammatory pathways. CONCLUSION: Understanding the potential association and the therapeutic value of ANGPTL4 for regulating lipid metabolism and inflammation could contribute to drug discovery and therapeutic development.
Zhang et al. (Tue,) conducted a review in Lipid metabolism and inflammation. ANGPTL4 was evaluated. ANGPTL4 acts as a key node linking lipid metabolism and inflammation by affecting critical enzymes, regulatory factors, and receptors of lipid oxidation, synthesis, and peroxidation.
