Genetic enhancement of hepatic mitochondrial fatty acid oxidation (FAO) via CPT1A overexpression rescues insulin resistance and reduces steatosis in obesity models without increasing oxidative stress.
This paper highlights that simply increasing fat oxidation in the liver is beneficial for insulin resistance, but current pharmacological inhibitors fail due to side effects. Future therapies might target the CPT1 enzyme directly to boost oxidation without causing liver damage, potentially treating fatty liver and insulin resistance simultaneously.
ModerateSupportsMEDIUM confidence
Recent studies (117, 130) overexpressing an active and malonyl-CoA-insensitive mutant form of CPT1A (CPT1AM) in obese rodents show that permanently enhanced liver FAO not only rescues impaired hepatic, muscle, and WAT insulin signaling in these animals, but also reduces steatosis, inflammation, and adiposity (Fig. 3).
Why this rating
Evidence is based on rodent models (genetic overexpression), not human clinical trials.
