Inhibition of SIRT4 in liver and muscle cells increases fatty acid oxidation and mitochondrial gene expression, primarily through the upregulation of SIRT1 and activation of AMPK.
This research suggests that reducing SIRT4 activity could help the liver and muscles burn more fat. This mechanism is currently being explored for potential treatments for type 2 diabetes and conditions involving ectopic fat storage, but no direct human intervention is available yet.
ModerateSupportsMEDIUM confidence
Taken together these findings demonstrate that SIRT4 inhibition increases fat oxidative capacity in liver and mitochondrial function in muscle, which might provide therapeutic benefits for diseases associated with ectopic lipid storage such as type 2 diabetes.
Why this rating
The study uses in vitro (hepatocytes, myotubes) and in vivo (mice) models, but lacks human clinical data.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
