Associations between ABO blood groups and pancreatic ductal adenocarcinoma: influence on resection status and survival
el Jellas, Khadija; Hoem, Dag; Hagen, Kristin Gjerde; Kalvenes, May Britt; Aziz, Sura Mohammed; Steine, Solrun; Immervoll, Heike; Johansson, Stefan; Molven, Anders (Peer reviewed; Journal article, 2017-07)Both serology‐based and genetic studies have reported an association between pancreatic cancer risk and ABO blood groups. We have investigated this relationship in a cohort of pancreatic cancer patients from Western Norway ... -
Biomarker profiles in serum and saliva of experimental Sjögren's syndrome: associations with specific autoimmune manifestations
Delaleu, Nicolas Hervé; Immervoll, Heike; Cornelius, Janet; Jonsson, Roland (Peer reviewed; Journal article, 2008-02-20)Introduction Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly targets the exocrine glands. The aim of this study was to investigate the involvement of 87 proteins measured in serum and 75 proteins ... -
Cancer stem cells as mediators of treatment resistance in brain tumors: Status and controversies
Sakariassen, Per Øystein; Immervoll, Heike; Chekenya, Martha (Peer reviewed; Journal article, 2007-11)Malignant primary brain tumors are characterized by a short median survival and an almost 100% tumorrelated mortality. Despite the addition of new chemotherapy regimes, the overall survival has improved marginally, and ... -
Expression of the "stem cell marker" CD133 in pancreas and pancreatic ductal adenocarcinomas
Immervoll, Heike; Hoem, Dag; Sakariassen, Per Øystein; Steffensen, Ole Johnny; Molven, Anders (Peer reviewed; Journal article, 2008-02-08)Background It has been suggested that a small population of cells with unique self-renewal properties and malignant potential exists in solid tumors. Such "cancer stem cells" have been isolated by flow cytometry, followed ... -
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 ... -
Impact of KRAS, BRAF, PIK3CA, TP53 status and intraindividual mutation heterogeneity on outcome after liver resection for colorectal cancer metastases
Løes, Inger Marie; Immervoll, Heike; Sorbye, Halfdan; Angelsen, Jon-Helge; Horn, Arild; Knappskog, Stian; Lønning, Per Eystein (Peer reviewed; Journal article, 2016-04)We determined prognostic impact of KRAS, BRAF, PIK3CA and TP53 mutation status and mutation heterogeneity among 164 colorectal cancer (CRC) patients undergoing liver resections for metastatic disease. Mutation status was ... -
The mucinous domain of pancreatic carboxyl-ester lipase (CEL) contains core 1/core 2 O-glycans that can be modified by ABO blood group determinants
El Jellas, Khadija; Johansson, Bente Berg; Fjeld, Karianne; Antonopoulos, Aristotelis; Immervoll, Heike; Choi, Man Hung; Hoem, Dag; Lowe, Mark E.; Lombardo, Dominique; Njølstad, Pål Rasmus; Dell, Anne; Mas, Eric; Haslam, Stuart M.; Molven, Anders (Peer reviewed; Journal article, 2018)Carboxyl-ester lipase (CEL) is a pancreatic fat-digesting enzyme associated with human disease. Rare mutations in the CEL gene cause a syndrome of pancreatic exocrine and endocrine dysfunction denoted MODY8, whereas a ... -
Performance comparison of three BRAF V600E detection methods in malignant melanoma and colorectal cancer specimen
Løes, Inger Marie; Immervoll, Heike; Angelsen, Jon-Helge; Horn, Arild; Geisler, Jürgen; Busch, Christian; Lønning, Per Eystein; Knappskog, Stian (Peer reviewed; Journal article, 2015-02)Personalized cancer care requires reliable biomarkers. While the BRAF V600E mutation is implemented in the clinic, no method for its detection has so far been established as reference. We aimed to perform a comprehensive ... -
Targeting the NG2/CSPG4 Proteoglycan Retards Tumour Growth and Angiogenesis in Preclinical Models of GBM and Melanoma
Wang, Jian; Svendsen, Agnete; Kmiecik, Justyna; Immervoll, Heike; Skaftnesmo, Kai Ove; Planagumà, Jesús; Reed, Rolf K.; Bjerkvig, Rolf; Miletic, Hrvoje; Enger, Per Øyvind; Rygh, Cecilie Brekke; Chekenya, Martha (Peer reviewed; Journal article, 2011-07-29)Aberrant expression of the progenitor marker Neuron-glia 2 (NG2/CSPG4) or melanoma proteoglycan on cancer cells and angiogenic vasculature is associated with an aggressive disease course in several malignancies including ...
