Pioneer postdoc announcement

UNIVERSITY OF BERGEN

Postdoctoral Research Fellow in pediatric cancer biology

UiB – Knowledge that shapes society

Through robust and close interaction with the world around us – globally, nationally and locally – we shall be instrumental in building a society based on knowledge, skills and attitudes.

Do you want to take part in shaping the future?

Postdoctoral Research Fellow position

Funded by a highly competitive Pioneer Grant for novel and game-changing projects.

At the Faculty of Medicine, Department of Clinical Science, a full-time (100 %) position as Postdoctoral Research Fellow is available for a period of two (2) years. The position is part of the project, ”KidImmune – Autoimmune mechanisms in pediatric cancer”, financed by the Norwegian Cancer Society Pioneer Program. See http://kidimmune.no for more information.

Our small, enthusiastic group consisting of Ola Myklebost, an experienced cell biologist and cancer researcher, and research fellow Anastassia Serguienko, who made the entirely novel discoveries on which this project is built, has the focus completely on this project. Our findings open up a Pandora’s box of fascinating questions that need answers. We have laid a solid foundation of clinical sample collections, proteomic data, technologies, and cell models to give the candidate a flying start.

We have access to expert in-house core facilities for genomics, proteomics, flow cytometry and advanced microscopy.

About the project/work tasks:

  • Investigations on how patient autoantibodies may influence important processes in normal and cancer cells in culture
  • Using immunohistochemistry, advanced microscopy, flow cytometry, protein chemistry, and various functional assays

Qualifications and personal qualities:

  • The applicant must hold a Norwegian PhD or an equivalent degree or have submitted the doctoral thesis prior to the application deadline. It is a condition of employment that the PhD has been awarded at the latest within 31.12.2022
  • Work independently and in a structured manner and have good ability to communicate and cooperate.
  • Proficiency in both written and oral English is required. Proficiency in Norwegian would be an advantage
  • Special requirements for the position: Project experience from mammalian molecular and cell biology is required, including cellular structure and function or advanced human immunology. Competence in excess of course experience in immunology, protein chemistry and function, advanced cell microscopy, or cancer biology would be an advantage

About the position of postdoctoral research fellow:

The position of postdoctoral research fellow is a fixed-term appointment with the primary objective of qualifying the appointee for work in top academic positions. Postdoctoral fellowships are fixed term positions. You can not be employed as a postdoctoral fellow for more than one three-year period at the same institution.

Informasjon for pasienter

I alle våre prosjekter bruker vi prøver fra og opplysninger om pasienter for å forstå disse komplekse sykdommene bedre og identifisere sider ved dem som kan utnyttes for bedre diagnostikk, behandling eller oppfølgning.

I to nye prosjekter studerer vi arvelige risikovarianter som kan gi stor risiko for sarkom, og, på bakgrunn av en intervjuundersøkelse med pasienter i NoSarC-prosjektet, arbeider vi med prosedyrer som kan velge ut hvilke av disse variantene som vi vet nok om til å melde tilbake til pasienten, og hvordan dette bør gjøres.

I et annet prosjekt studerer vi om pasientene i NoSarC har antistoff rette mot kreftcellene, og om disse kan utnyttes i nye former for immunterapi.

Informasjon om osteosarkomstudien i det internasjonale kreftgenomprosjektet (ICGC)

I 2011 ble vi med på en internasjonal studie av arvestoffets struktur i prøver fra noen av Radiumhospitalets pasienter med osteosarkom (ondartede bensvulster). Dette var en forlengelse av vårt samarbeid i det europeiske «Network of Excellence on Bone Tumours», der vi var av de få som hadde en høykvalitetssamling av prøver fra slike pasienter, som var samlet over flere år av ortopedene. I dette prosjektet skulle hele arvestoffet (DNAet, to ganger 3 milliarder byggesteiner) analysert i både blod og svulst og sammenlignet for hver pasient. Vi innhentet derfor samtykke fra de aktuelle pasientene, og ba også om en blodprøve fra hver.

Dette er svært kostbare analyser, og mange av svulstprøvene hadde ikke høy nok kvalitet, det kunne være lite kreftvev i dem, eller arvestoffet kunne være ødelagt pga innsamlings- eller lagringsprosdyerene, men vi fikk med 27 slike par med svulst- og blodprøver. Resultatene har bidratt til flere meget høyprofilert vitenskapelige artikler, og både data og prøver er ennå til stor nytte i nye prosjekter.

Dette var den opprinnelige artiklen der resultatene fra våre pasienter ble presentert:

For tiden bruker vi en del av disse resultatene i et prosjekt der vi prøver å forstå hvorfor noen sarkomtyper og hvilke enkeltsvulster responderer på immunterapi og andre ikke, i et prosjekt finansiert av Norges Forskningsråd. Det viste seg i en amerikansk klinisk utprøving der både bløtvevs- og bensarkomer ble behandlet med immunsjekkpunkthemmeren pembrolizumab (SARC028) at bare en osteosarkompasient fikk respons, mens en rekke pasienter med bestemte typer bløtvessarkom responderte.
