At the Institute of Clinical Biochemistry, University of Oslo

We are a group of people who share common interest in mitochondrial function and mitochondrial DNA maintenance and implication in pathogenesity and aging, especially aging-related syndromes such as neurodegeneration and cancer.

We are an associated group of the Laboratory for molecular biology at the Centre of Molecular Biology and Neuroscience, and located at Rikshospitalet in Gaustad.



The People:

Pia Madeleine Øistad PhD student, Ruth Halsne PhD student, Pia Nenseth Auk Technician, Janne Maren Strand Technician,  Lars Eide Group leader, Ass.Prof.


Mitochondria play a central role in cellular processes as they actively participate in energy production, calcium buffering and apoptosis control. Erosion of mitochondrial function is

thought to underlie the progressive cell death observed in different neurodegenerative diseases and in aging in general. Damages to mitochondrial DNA are fixed by

specialized DNA repair systems, but extensive damage exceed repair capacity and can result in mitochondrial dysfunction which predisposes to cell death.

In our projects, we investigate how mitochondrial DNA status determines cellular tolerance to stress conditions.

Understanding molecular mechanisms that contribute to bioenergetic failure is essential for protection as well as treatment of disease.


We are collaborating with research groups within neuroscience as well as other areas focusing on oxidative stress, mitochondrial DNA damage and mitochondrial function.

In collaboration with Berit Woldseth at the Department of Medical Biochemistry, Rikshospitalet, we are establishing diagnostics for detection of mitochondrial diseases
