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

Scientific Claim

PGC-1α overexpression is associated with increased PMP70 protein levels in human primary myotubes.

Original Statement

“peroxisomal membrane protein 70 kDa (PMP70), PEX19, and mitochondrial citrate synthetase protein content were significantly elevated (P < 0.05)”

From study:Overexpression of PGC-1α increases peroxisomal activity and mitochondrial fatty acid oxidation in human primary myotubes.

Similar Assertions

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

78%

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
