Genetic mitochondrial diseases occur as a result of mutations in the nuclear or mitochondrial genome. Such impairment is often associated with dysfunctions in proteins which are part of the respiratory system. First, our aim was to study whether the time elapsed from death until dissection has a significant impact on the detected protein damage and thus affects or distorts the results.

To address this topic, brain samples were obtained from mice. After sacrificing the animals, they were stored under the same conditions as the remains of patients, and dissected in a similar time regime as when obtaining autopsy samples from deceased patients.

Our results demonstrated no significant alterations in protein levels and damage analyzed at successive time points. Our results suggest that autopsy samples can be used for the study of oxidative damage, which can extend and direct further research toward the diagnosis of mitochondrial diseases, which are accompanied by elevated levels of reactive oxygen species.
