Increasing the expression of PGC1a enhances fatty acid oxidation and mitochondrial function in peripheral tissues, which prevents lipotoxicity and improves insulin sensitivity.
Increasing PGC1a activity helps muscles and liver burn fat more efficiently, reducing the toxic buildup of lipids in organs and improving how the body handles glucose.
GoodSupportsHIGH confidence
PGC1a is a transcription factor that has been shown to participate in pathways controlling glucose homoeostasis and promoting fatty acid oxidation via increasing mitochondrial function and activity. Therefore, PGC1a may be a critical link in the pathogenesis of type 2 diabetes by preventing lipotoxicity.
Why this rating
Supported by mouse models showing cold intolerance and metabolic changes.

- When adipose tissue expansion capacity is exceeded, lipid accumulates in non-adipose tissues (lipotoxicity), which directly causes insulin resistance and metabolic syndrome.Good
- Activation of PPARg increases lipid storage capacity in adipose tissue, thereby preventing lipotoxicity and improving insulin sensitivity.Good
