• Expression of the progenitor marker NG2/CSPG4 predicts poor survival and resistance to ionising radiation in glioblastoma 

      Svendsen, Agnete; Verhoeff, Joost J. C.; Immervoll, Heike; Brøgger, Jan C.; Kmiecik, Justyna; Poli, Aurélie; Netland, Inger A.; Planagumà, Jesús; Torsvik, Anja; Sakariassen, Per Øystein; Bjerkvig, Rolf; Enger, Per Øyvind; Tronstad, Karl Johan (Peer reviewed; Journal article, 2011-08-24)
      Glioblastoma (GBM) is a highly aggressive brain tumour, where patients respond poorly to radiotherapy and exhibit dismal survival outcomes. The mechanisms of radioresistance are not completely understood. However, cancer ...
    • Runaway multi-allelic copy number variation at the α-defensin locus in African and Asian populations 

      Hughes, Timothy; Hansson, Lars; Akkouh, Ibrahim; Hajdarevic, Riad; Bringsli, Jorunn; Torsvik, Anja; Inderhaug, Elin; Steen, Vidar Martin; Djurovic, Srdjan (Journal article; Peer reviewed, 2020-06-04)
      Alpha defensins are anti-microbial peptides of the innate immune system. The defensin A1 and A3 genes are located in a repeat array of variable copy number (the DEFA1A3 locus) and encode the human neutrophil peptides 1, 2 ...
    • U-251 revisited: genetic drift and phenotypic consequences of long-term cultures of glioblastoma cells 

      Torsvik, Anja; Stieber, Daniel; Enger, Per Øyvind; Golebiewska, Anna; Molven, Anders; Svendsen, Agnete; Westermark, Bengt; Niclou, Simone P.; Olsen, Thale Kristin; Chekenya, PhD, Dr Philos, Dr. Martha; Bjerkvig, Rolf (Peer reviewed; Journal article, 2014-08)
      It is well known that in vitro subculture represents a selection pressure on cell lines, and over time this may result in a genetic drift in the cancer cells. In addition, long-term cultures harbor the risk of cross-contamination ...
