The Claim
Lactate acts as a signaling molecule that alters mitochondrial morphology and modulates gene expression associated with mitochondrial biogenesis through ROS-mediated pathways, independent of its function as a metabolic fuel.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Lactate, a molecule produced during exercise, directly changes the shape of mitochondria and turns on genes involved in creating new mitochondria, through pathways involving reactive oxygen species, regardless of its role in energy production.
See the scientific wording
Lactate may serve as a signaling molecule that influences mitochondrial morphology and gene expression related to biogenesis, independent of its role as a metabolic fuel, based on in vitro evidence of ROS-mediated pathways.
When lactate builds up inside muscle cells, it enters the mitochondria and gets converted into pyruvate, which triggers a small burst of reactive oxygen species. These molecules activate signals that cause the mitochondria to multiply and change shape, making the cell better at producing energy.
What the research says
1 studyStudy: Intracellular Shuttle: The Lactate Aerobic Metabolism
This study says lactate, a substance made during exercise, might send signals to muscle cells to make more or change their energy factories (mitochondria) by causing small bursts of reactive oxygen species — and this happens even if lactate isn’t being burned for energy. It’s like lactate is whispering to the cells to grow more mitochondria.
