Background:

  • Mitochondria generate cellular energy via oxidative phosphorylation.
  • Mitochondrial DNA (mtDNA) encodes critical respiratory chain subunits.
  • mtDNA mutations are implicated in numerous diseases and aging.

Purpose of the Study:

  • To review recent advancements in mitochondrial medicine.
  • To highlight the role of mtDNA in energy production and disease.

Main Methods:

  • Literature review of recent studies in mitochondrial medicine.
  • Analysis of identified pathogenic mtDNA mutations and their clinical relevance.

Main Results:

  • Over 50 disease-causing mtDNA mutations have been identified.
