Description of the subject area

The Schlisio lab at Karolinska Institute, Sweden, seeks a research specialist to work on molecular principles of tumor formation arising from the sympathoadrenal cell lineage (neuroblastoma, pheochromocytoma, paraganglioma) to explore cell of origin, disease initiation and tumor heterogeneity.


Your mission

We are seeking a motivated, creative research specialist candidate interested in tumor mouse models arising from the sympathoadrenal lineage, such as neuroblastoma (NB) and pheochromocytoma (PCC), with the aim to understand the molecular principles of these tumors at a previously unprecedented level. The neuroblastoma cell of origin is thought to be a developing sympathoblast, however, its precise cell of origin remains unknown. Single cell transcriptomics will identify gene expression clusters that are prominent in specific embryonic sympathoadrenal developmental stages in NB and PCC. Identifying the cell(s) of NB/PCC origin and their temporal development will provide mechanistic insight into: disease initiation, heterogeneity, progression, clinical behavior and spontaneous NB regression.

The project involves novel neuroblastoma and pheochromocytoma animal models that are generated in our lab to investigate the dynamics of tumor formation in a single cell mode to compare events in the early tumor with already defined trajectory. This approach may explain the role of known mutations and will help to devise new tumor-differentiating strategies in vivo.

We are currently addressing the following questions:

  • Understanding the clinical heterogeneity of neuroblastoma: What distinguishes the “favorable” vs the “unfavorable” neuroblastoma?
  • What unique signatures can be found in the spontaneously regressing neuroblastoma?
  • Do neuroblastoma types represent regulatory patterns in early or late embryonic sympathoblast/crest populations?
  • Can we identify cell-of-origin subpopulations for neuroblastoma initiation?

Eligibility requirements

To be eligible for employment as a Research Specialist, in addition to holding a Degree of Doctor, PhD, or having equivalent scientific expertise, the applicant must have demonstrated research expertise as well as have documented research experience after defending their doctoral dissertation.

To be eligible for the position, you must have completed your doctoral degree in neuroscience or equivalent as well as FELASA B certificate are required.


Assessment criteria

The applicant must have demonstrated relevant research expertise in animal experiments, such as neuroblastoma and pheochromocytoma tumour mouse models, RNAscope and confocal microscopy,  immunohistochemistry, neuro- and protein biochemistry, and intravital imaging. 

After an overall assessment of the expertise and merits of the applicants in relation to the subject area, Karolinska Institutet will determine which of them has the best potential to contribute to a positive development of the activities at KI.
