Metabolic disorders About themeThe mission of the theme is to understand cellular bioenergetics in health and disease at all levels of complexity. The gained knowledge will enable us to develop preventive and supportive measures and substantial contributions towards the development of rational treatment strategies for mitochondrial diseases.
Human cells require energy in the form of ATP to function adequately. In most cell types, ATP is primarily generated by mitochondria, which are also key players in other cellular processes, such as adaptive thermogenesis, ion homeostasis, innate immune responses, and programmed cell death (apoptosis). Mitochondrial dysfunction, defined as a disturbance in the function of the oxidative phosphorylation system, is not only observed in monogenic mitochondrial disorders but is also associated with more common pathologic diseases and conditions, such as genetic forms of Parkinson’s disease, certain types of cancer like pheochromocytomas, heart failure, diabetes mellitus, epilepsy, and with adverse drug effects like nucleoside reverse transcriptase inhibitors (NRTIs).
To realize this mission, we defined three lines of research along the spectrum of molecule-man-population: (i) structure and function of molecules and complexes; (ii) cellular consequences of hampered oxidative phosphorylation; (iii) clinical aspects of mitochondrial diseases.
- Structure and function of molecules and complexes
- Cellular consequences
- Clinical aspects
- We aim to identify new gene defects in the oxidative phosphorylation system and to characterize the cellular mechanisms involved.
- We aim to elucidate the molecular mechanism and regulation of mitochondrial complex I based on the atomic structure.
- We aim to resolve the complete assembly pathway of mitochondrial complex I and to identify and functionally characterize new components of the assembly machinery.
- We will study the dynamics of the mitochondrial complexome in health and disease.
- We will explore the tissue-specific inventory and regulation of the complexes of oxidative phosphorylation and their correlation with specific phenotypes.
- We will investigate the links and mechanisms connecting genetic defects with organ-specific disease phenotypes.
- We will further develop tools to monitor the metabolic state and bio-energetic status of mitochondria in living cells and tissues.
- We will study the influence of environmental factors on the progression of mitochondrial disease.
- We will develop a toolbox of biomarkers and relevant clinical outcome measures to monitor progression of mitochondrial disease and the effect of therapeutic interventions.
- We will perform long-term follow-up studies on defined patient cohorts.
- We will explore new therapeutic approaches to mitochondrial diseases.
