Professor Jo Poulton’s Oxford research group:
There are no good treatments for patients with established mitochondrial disease. Over the past five years Prof Jo Poulton's team have developed a novel method for quantifying mitophagy (a type of mitochondrial quality control), in cells from mitochondrial patients. Furthermore, they have developed various models on which to test these. Current research areas build on this work:
- The team are now identifying drug modulators of mitophagy which may prevent progression or even ameliorate mitochondrial diseases. Their work on the effects of Doxorubicin (widely used in oncology) are directly relevant to preventing its cardiotoxicity (resulting in heart transplantation).
- They are looking to develop a way to improve the outcome of pre-implantation genetic diagnosis and mitochondrial replacement therapy to prevent mtDNA diseases.

Research and development work in Oxford Medical Genetics Laboratories:
The mitochondrial genetics laboratory team are committed to translating technical developments and research findings into routine mitochondrial diagnostic service. This ensures continual improvement in diagnostic yield, more rapid & accurate diagnoses for patients and their families, and informs genetic management.
Current areas of development include:
- Expanding the use of next generation sequencing approaches to identify the underlying genetic cause in an ever increasing proportion of patients, particularly in PDH deficiency, mtDNA disease and mtDNA maintenance disorders.
- Implementation of whole exome sequencing into the diagnostic service
- Improved assays for mitochondrial DNA rearrangements
- Improved assays for mitochondrial DNA depletion
In addition, the team collaborate closely with colleagues across the 3 centres, on a varied array of research projects to further characterise mitochondrial disorders and develop new treatments.
