The extracellular bone marrow microenvironment — a proteomic comparison of constitutive protein release by in vitro cultured osteoblasts and mesenchymal stem cells
Aasebø, Elise; Birkeland, Even; Selheim, Frode; Berven, Frode; Brenner, Annette; Bruserud, Øystein (Journal article; Peer reviewed, 2021)Mesenchymal stem cells (MSCs) and osteoblasts are bone marrow stromal cells that contribute to the formation of stem cell niches and support normal hematopoiesis, leukemogenesis and development of metastases from distant ... -
High-Throughput Mutation Profiling of Primary and Metastatic Endometrial Cancers Identifies KRAS, FGFR2 and PIK3CA to Be Frequently Mutated
Krakstad, Camilla; Birkeland, Even; Seidel, Danila; Kusonmano, Kanthida; Petersen, Kjell; Mjøs, Siv; Høivik, Erling Andre; Wik, Elisabeth; Halle, Mari Kyllesø; Øyan, Anne Margrete; Kalland, Karl-Henning; Werner, Henrica Maria Johanna; Trovik, Jone; Salvesen, Helga Birgitte (Peer reviewed; Journal article, 2012-12-27)Background: Despite being the most common pelvic gynecologic malignancy in industrialized countries, no targeted therapies are available for patients with metastatic endometrial carcinoma. In order to improve treatment, ... -
Integrated Genomic Analysis of the 8q24 Amplification in Endometrial Cancers Identifies ATAD2 as Essential to MYC-Dependent Cancers
Ræder, Maria B.; Birkeland, Even; Trovik, Jone; Krakstad, Camilla; Shehata, Shyemaa; Schumacher, Steven; Zack, Travis I.; Krohn, Antje; Werner, Henrica Maria Johanna; Moody, Susan E.; Wik, Elisabeth; Stefansson, Ingunn; Holst, Frederik; Øyan, Anne Margrete; Tamayo, Pablo; Mesirov, Jill P.; Kalland, Karl-Henning; Akslen, Lars A.; Simon, Ronald; Beroukhim, Rameen; Salvesen, Helga Birgitte (Peer reviewed; Journal article, 2013-02-05)Chromosome 8q24 is the most commonly amplified region across multiple cancer types, and the typical length of the amplification suggests that it may target additional genes to MYC. To explore the roles of the genes most ... -
KRAS gene amplification and overexpression but not mutation associates with aggressive and metastatic endometrial cancer
Birkeland, Even; Wik, Elisabeth; Mjøs, Siv; Høivik, Erling Andre; Trovik, Jone; Werner, Henrica Maria Johanna; Kusonmano, Kanthida; Petersen, Kjell; Ræder, Maria B.; Holst, Frederik; Øyan, Anne Margrete; Kalland, Karl-Henning; Akslen, Lars A.; Simon, Ronald; Krakstad, Camilla; Salvesen, Helga Birgitte (Peer reviewed; Journal article, 2012)BACKGROUND: Three quarter of endometrial carcinomas are treated at early stage. Still, 15 to 20% of these patients experience recurrence, with little effect from systemic therapies. Homo sapiens v-Ki-ras2 Kirsten rat sarcoma ... -
Mutations and gene amplifications in Endometrial Carcinomas. “Clinical characteristics and potential targets for therapy related to KRAS, MYC, ATAD2, PIK3CA and FGFR2 alterations”
Birkeland, Even (Doctoral thesis; Peer reviewed, 2013-09-20)Background: Incidence of endometrial cancer is increasing in industrialised countries. Despite early diagnosis and generally good prognosis, around one fourth of cases follow an aggressive path with few effective treatment ... -
PIK3CA exon9 mutations associate with reduced survival, and are highly concordant between matching primary tumors and metastases in endometrial cancer
Mjøs, Siv; Werner, Henrica Maria Johanna; Birkeland, Even; Holst, Frederik; Berg, Anna; Halle, Mari Kyllesø; Tangen, Ingvild Løberg; Kusonmano, Kanthida; Mauland, Karen Klepsland; Øyan, Anne Margrete; Kalland, Karl-Henning; Lewis, Aurelia Eva; Mills, Gordon B.; Krakstad, Camilla; Trovik, Jone; Salvesen, Helga; Høivik, Erling Andre (Peer reviewed; Journal article, 2017-08-31)Mutations of the phosphoinositide-3-kinase (PI3K) catalytic subunit alpha gene (PIK3CA) are frequent in endometrial cancer. We sequenced exon9 and exon20 of PIK3CA in 280 primary endometrial cancers to assess the relationship ... -
Stathmin expression associates with vascular and immune responses in aggressive breast cancer subgroups
Askeland, Cecilie; Wik, Elisabeth; Finne, Kenneth; Birkeland, Even; Arnes, Jarle; Collett, Karin; Knutsvik, Gøril; Krüger, Kristi; Davidsen, Benedicte; Aas, Turid; Eide, Geir Egil; Stefansson, Ingunn; Foulkes, William; Akslen, Lars A. (Journal article; Peer reviewed, 2020)Studies indicate that stathmin expression associates with PI3K activation in breast cancer, suggesting stathmin as a marker for targetable patient subgroups. Here we assessed stathmin in relation to tumour proliferation, ... -
Stathmin Protein Level, a Potential Predictive Marker for Taxane Treatment Response in Endometrial Cancer
Werner, Henrica Maria Johanna; Trovik, Jone; Halle, Mari Kyllesø; Wik, Elisabeth; Akslen, Lars A.; Birkeland, Even; Bredholt, Therese; Tangen, Ingvild Løberg; Krakstad, Camilla; Salvesen, Helga Birgitte (Peer reviewed; Journal article, 2014-02-25)Stathmin is a prognostic marker in many cancers, including endometrial cancer. Preclinical studies, predominantly in breast cancer, have suggested that stathmin may additionally be a predictive marker for response to ...
