Paragangliomas are tumors that originate from chromaffin cells in the adrenal medulla (also called paraganglioma) or sympathetic ganglia. Chromaffin cells are neuro-endocrine cells that can procedure catecholamines such as adrenaline, noradrenaline and dopamine. Every year, between 100 and 150 new paraganglioma cases are reported in the Netherlands. Currently, there is no effective treatment for patients with metastatic or inoperable paraganglioma. There is an urgent clinical need for development of therapeutics against this disease, which requires a better understanding of the etiology and pathophysiology of paraganglioma. About 40 percent of the paraganglioma can be explained by a germline mutation in a variety of genes. So far, 18 paraganglioma-related genes have been identified. A mutation in one of these paraganglioma-related genes, the succinate dehydrogenase B (SDHB), is the strongest indicator of malignancy. The SDHB protein is part of a four subunit (A-D) protein complex, the succinate dehydrogenase (SDH) complex. The SDH complex converts succinate to fumarate, one of the steps of the TCA cycle. When this complex is dysfunctional there is a build-up of succinate in the cell. Succinate stabilizes hypoxia-inducible transcription factors (HIFs). HIF-targets are subsequently transcribed and in turn boost proliferation and angiogenesis, two essential processes of tumor formation. To further unravel the pathogenesis and etiology of this disease and to develop and test new therapeutic strategies we use an existing zebrafish as animal model.

Tasks and responsibilities

  • The PhD candidate will design and perform scientific research in health and disease.
  • Characterization of inter-renal tumor formation in systemic and tissue-specific sdhb mutant zebrafish.
  • Identification of potentially therapeutic targets and drugs.
  • Generates and critically analyses the data in order to contribute to scientific publications and presents findings at scientific meetings.
  • Works in a team with other students and scientists to discuss, plans and performs research in a stimulating environment.
  • Works in a highly international research group with fellows from many countries.
  • Supervise MSc and/or BSc students.
  • Write and defend a PhD thesis within three years of starting the project.
  • Candidate will take part in the graduate school of Radboudumc.


  • MSc degree in Biomedical Sciences or Molecular Life Sciences or a related field.
  • Experience with molecular and cell biology is considered a strong plus.
  • Article 9 of the Dutch Law on Animal Experimentation is considered a strong plus.
  • Experience with in vitro and in vivo modeling using zebrafish and/or cell lines is considered a plus.
  • Experience with bio-informatics is considered a plus.
  • Structured working style.
  • A strong motivation, flexibility, and willingness to learn.
  • Critical scientific attitude and be able to work both independently as well as in a group.
  • Excellent communication skills; oral and in writing.


Upon commencement of employment we require a certificate of conduct (Verklaring Omtrent het Gedrag, VOG) and there will be, depending on the type of job, a screening based on the provided cv. Radboud university medical center's HR Department will apply for this certificate on your behalf.
