Furan fatty acids reprogram hepatic lipid metabolism via acyl-CoA conjugates in obesity.

Furan fatty acids (FuFAs) in fish oil reprogram hepatic lipid metabolism through acyl-CoA conjugates, with 11U3-2M showing significant metabolic benefits in obese mice.

• Why it matters: Understanding the molecular mediators of fish oil's cardiometabolic benefits can improve dietary strategies for metabolic health, as FuFAs are potential key regulators.
• What they did: The study identified and quantified FuFA species in omega-3 formulations and synthesized analogs, testing their effects in a diet-induced obesity mouse model, including 11U3-2M.
• The result: 11U3-2M reduced fat accumulation, inflammation, glucose intolerance, dyslipidemia, and hepatic steatosis, by accumulating acyl-CoA conjugates that activate PPARα signaling and inhibit acetyl-CoA carboxylases, reprogramming hepatic lipid metabolism.
