PGC-1α boosts fat-burning power in muscle cells
Overexpression of PGC-1α increases peroxisomal activity and mitochondrial fatty acid oxidation in human primary myotubes.

Scientists gave muscle cells a special gene (PGC-1α) and found that it made the cells better at breaking down fats. They saw more proteins and genes involved in fat burning, and the cells burned more of a special fat called lignoceric acid.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Tesamorelin upregulates genes involved in oxidative phosphorylation across the electron transport chain and in fatty acid oxidation, leading to cellular-level metabolic remodeling that enhances fat burning efficiency at the mitochondrial level.
When muscle cells in a lab have more PGC-1α protein, they show higher levels of PMP70, which is a protein involved in peroxisome function. This finding is from the abstract summary - full study details were not available
Increasing PGC-1α in muscle cells leads to higher levels of mRNA for breaking down fats in peroxisomes. This finding is from the abstract summary - full study details were not available
When PGC-1α is increased in muscle cells, they break down a specific type of fat (lignoceric acid) more efficiently using both peroxisomes and mitochondria. This finding is from the abstract summary - full study details were not available
