Research groups
Currently, the division consists of three research groups focusing on different aspects of mitochondrial biology. The division has a close collaboration with the Centre for Inherited Metabolic Diseases at Karolinska University Hospital, and the Max Planck Institute for Biology of Ageing - Karolinska Institutet Laboratory (MPI-KI) is integrated into our laboratory.
Transcription of mitochondrial DNA by POLRMT
Nils-Göran Larsson
The mitochondrion is a key player in cellular function and dysfunctional mitochondria have been implicated in a number of disorders as well as in the process of normal ageing. Our research group is interested in fundamental questions related to mitochondrial biology. How is the number and the function of mitochondria regulated? What happens in a cell with dysfunctional mitochondria? How does mitochondrial dysfunction cause human disease?
Anna Wredenberg
Our research tries to identify the molecular consequences of metabolic derangements, by understanding how mitochondria function within the metabolic system. We also have a special focus on understanding the turnover of mitochondrial transcripts, and how changes in mitochondrial gene expression is regulated on a post-transcriptional level.

The central theme of the Rorbach lab is the molecular control of mitochondrial gene expression and its influence on physiology. We use genetic, proteomic, single-molecule and cryo-EM methods to reveal mechanisms and to identify novel factors involved in mitochondrial RNA metabolism. These interdisciplinary approaches help us to explore a poorly-understood area of mitochondrial biology with direct relevance to human health.
