01 / DESIGN
What was studied?
Genetically deficient mice and patient-derived fibroblasts were used to test mitochondrial function and responses to physiological challenges.
02 / FINDINGS
What did the researchers report?
Exercise endurance and selected mitochondrial measurements improved, but cold tolerance and cardiolipin composition did not. Cell responses appeared to depend on genotype.
03 / LIMITS
How should it be interpreted?
These contrasting endpoints argue against a single universal mitochondrial effect. Patient-derived cells are useful models but cannot replace a controlled clinical trial.
