Laboratory of Bioenergetics

Laboratory of Bioenergetics

We study the physiology of mitochondria, cell organelles responsible for most of the energy production on the molecular level. We use both animal models and cells derived from patients harbouring various mitochondrial disorders. Our research is focused mainly on:

  • Assembly of mitochondrial protein complexes and supercomplexes.
  • Human diseases caused by mutations in assembly factors of these enzyme complexes.
  • Development of protocols for diagnostics of mitochondrial diseases using patient-derived lymphocytes.
  • Identification of new mitochondrial genes that play a causal role in the metabolic syndrome and heart failure.



Functional characterization of ATP synthase deficiencies

ATP produced by the mitochondrial FoF1-ATP synthase represents a major source of energy for aerobic organisms. The proposed project is aimed to shedding light on the functional consequences of ATP synthase deficiencies using a model of knock-down of small subunits of the catalytic F1 part of the mammalian ATP synthase (γ, δ and ε).

The role of mitochondria in heart failure

To shed more light on whether OXPHOS defects can play a role in the development of heart failure, we analyse samples from patients undergoing heart transplants. We search for characteristic markers, which would be suitable for identification of new patients, as well as new potential targets for treatment. More

Bioenergetics of rare diseases

ATP synthase defects represent an important subgroup of inborn errors of metabolism. It may not be surprising if we take into account that ATP synthase is one of the key energy producing enzymes in a cell. We study biogenesis of this enzyme complex and the role of various other proteins in this process. More


TMEM70 disease

Animal models of human mitochondrial diseases enable detailed insight into pathogenic mechanisms, from molecular to organismal levels. More

Mitochondria dysfunction and Fanconi syndrome

Inborn disorders of energy provision by mitochondrial respiratory chain are the primary cause of numerous serious diseases, ranging from most severe encephalo-cardio-myopathies manifesting early after birth to various tissues-specific and milder disorders affecting mainly adults. More

Our new publication: High resistance to mitochondrial mutations

A developing organism requires high amounts of energy in the form of ATP. In higher eukaryotes, and thus in humans, more than 90 % of ATP is produced in mitochondria, a key organelle of the cellular catabolism. It is therefore not surprising that mitochondrial defects belong to the most frequent causes of metabolic diseases in children.  More
