Om
Barbara van Loon tok doktorgrad med utmerkelse (Magna cum Laude) ved Universitetet i Zürich (UZH, Sveits) i 2009. Hun fortsatte sin forskerkarriere som postdoktor ved Massachusetts Institute of Technology (Cambridge, USA). I 2011 startet hun som uavhengig gruppeleder ved Institutt for molekylære mekanismer ved sykdommer, UZH (Sveits). Hun ble tildelt Onsager Fellowship ved NTNU i 2016, og begynte som førsteamanuensis på NTNU. Barbara var videre en del av Outstanding Academic Fellows Program ved NTNU (2017-2021). Hun ble professor i 2020.
Forskningen til Barbara van Loon fokuserer på å bestemme virkningen av genom- og epigenomdynamikk på essensielle cellulære prosesser som er relevante for fysiologisk og patologisk utvikling. For hennes studier av den cellulære responsen på DNA-skade og betydningen dette har for kreft og utviklingsforstyrrelser i nervesystemet, ble Barbara i 2021 tildelt Anders Jahre medisinske pris til yngre forskere. Siden 2022 har Barbara vært medleder av Clinical Academic Group (CAG) for sjeldne genetiske sykdommer. CAG er en organisasjon støttet av Samarbeidsorganet i Helse Midt-Norge som koordinerer forskningsaktiviteter på tvers av tre helseforetak og ved NTNU, med hovedmål å fremme klinikken gjennom fremskritt innen forskning.

Research group: "Genome dynamics during physiological and disease development"
Our research
Numerous lethal and mutagenic DNA lesions are formed upon exposure to endogenous and exogenous damaging agents. The estimated steady-state level of endogenous DNA damage in mammalian cells is high, about 20’000 lesions per cell per day. Aberrant DNA bases represent significant portion of endogenous DNA damage. To maintain the integrity of genetic information organized within chromatin, cells need to efficiently repair the DNA. Accumulation of aberrant DNA bases has been tightly associated with aging, cancer development, as well as the onset of different neurological diseases. Aim of our research is to determine how presence of aberrant DNA bases influences essential cellular processes, like transcription and gene expression, as well as to identify different factors that ensure efficient repair. By using multidisciplinary approaches (including biochemistry, cell biology, genomics, proteomics, 3D culturing, imaging, CRISPR libraries, and computational biology) we focus on identification of pathomechanisms that lead to development of human diseases, in particular neurodevelopmental disorders and cancer, and which could potentially serve as basis for evolution of novel therapies.

Norsk klinisk-akademisk gruppe vil øke kompetansen på metakromatisk leukodystrofi
Helse Midt-Norge har opprettet en klinisk-akademisk gruppe for å øke kompetansen på diagnostisering, oppfølging og behandling av sjeldne, genetiske sykdommer. Gruppen skal blant annet se nærmere på metakromatisk leukodystrofi (MLD).
