      Hald, Sigurd; Bremnes, Roy M.; Al-Shibli, Khalid; Al-Saad, Samer; Andersen, Sigve; Stenvold, Helge; Busund, Lill-Tove; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)

    • High tumor cell expression of microRNA-21 in node positive non-small cell lung cancer predicts a favorable clinical outcome 

      Stenvold, Helge; Dønnem, Tom; Andersen, Sigve; Al-Saad, Samer; Valkov, Andrey Yurjevich; Pedersen, Mona Irene; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)

    • Independent and Tissue-Specific Prognostic Impact of miR-126 in Nonsmall Cell Lung Cancer 

      Dønnem, Tom; Lønvik, Kenneth; Eklo, Katrine; Berg, Thomas; Sørbye, Sveinung Wergeland; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Andersen, Sigve; Stenvold, Helge; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Angiogenesis is pivotal in tumor development. Vascular endothelial growth factor-A (VEGF-A) is considered one of the most important angiogenic factors, but lately several microRNAs (miRs) have been associated with vascular development. miR-126 has been related to tumor angiogenesis and in the regulation of VEGF-A. The authors aimed to investigate the prognostic impact of miR-126 and its co-expression ...

    • Kvinner med epilepsi. Følges retningslinjene i praksis? 

      Stenvold, Helge (Master thesis; Mastergradsoppgave, 2002-08-29)

    • MicroRNA Signatures in Tumor Tissue Related to Angiogenesis in Non-Small Cell Lung Cancer 

      Dønnem, Tom; Fenton, Christopher Graham; Lønvik, Kenneth; Berg, Thomas; Eklo, Katrine; Andersen, Sigve; Stenvold, Helge; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Angiogenesis is regarded as a hallmark in cancer development, and anti-angiogenic treatment is presently used in non-small cell lung cancer (NSCLC) patients. MicroRNAs (miRs) are small non-coding, endogenous, single stranded RNAs that regulate gene expression. In this study we aimed to identify significantly altered miRs related to angiogenesis in NSCLC. From a large cohort of 335 NSCLC patients, ...

    • Monocarboxylate transporters 1-4 in NSCLC: MCT1 is an independent prognostic marker for survival 

      Eilertsen, Marte; Andersen, Sigve; Al-Saad, Samer; Kiselev, Yury; Dønnem, Tom; Stenvold, Helge; Pettersen, Ingvild; Al-Shibli, Khalid; Richardsen, Elin; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)

    • Overexpression of the HIF Hydroxylases PHD1, PHD2, PHD3 and FIH Are Individually and Collectively Unfavorable Prognosticators for NSCLC Survival 

      Andersen, Sigve; Dønnem, Tom; Stenvold, Helge; Al-Saad, Samer; Al-Shibli, Khalid Ibrahim; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Hypoxia induced factors (HIFs) are at the heart of the adaptive mechanisms cancer cells must implement for survival. HIFs are regulated by four hydroxylases; Prolyl hydroxylase (PHD)-1,-2,-3 and factor inhibiting HIF (FIH). We aimed to investigate the prognostic impact of these oxygen sensors in NSCLC. Tumor tissue samples from 335 resected stages I to IIIA NSCLC patients was obtained and tissue ...

    • Prognostic Impact of MiR-155 in Non-Small Cell Lung Cancer Evaluated by in Situ Hybridization 

      Dønnem, Tom; Eklo, Katrine; Berg, Thomas; Sørbye, Sveinung Wergeland; Lønvik, Kenneth; Al-Saad, Samer; Al-Shibli, Khalid Ibrahim; Andersen, Sigve; Stenvold, Helge; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      In recent years, microRNAs (miRNAs) have been found to play an essential role in tumor development. In lung tumorigenesis, targets and pathways of miRNAs are being revealed, and further translational research in this field is warranted. MiR-155 is one of the miRNAs most consistently involved in various neoplastic diseases. We aimed to investigate the prognostic impact of the multifunctional miR-155 ...

    • Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2 

      Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ...

    • Severe hypercalcemia caused by parathyroid hormone in a rectal cancer metastasis: a case report 

      Brun, Vegard Heimly; Knutsen, Erik; Stenvold, Helge; Halvorsen, Hanne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-07)
      Background - Hypercalcemia of malignancy is relatively common in several cancers. However, in colorectal cancer, paraneoplastic phenomena that cause hypercalcemia is uncommon. In the few cases that are reported, secretion of parathyroid hormone-related peptide mediates the effect. We describe the first case of severe hypercalcemia mediated by intact parathyroid hormone secretion from a bone metastasis ...

    • Stage and tissue-specific prognostic impact of miR-182 in NSCLC 

      Stenvold, Helge; Dønnem, Tom; Andersen, Sigve; Al-Saad, Samer; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)

    • Transcription factor PAX6 as a novel prognostic factor and putative tumour suppressor in non-small cell lung cancer 

      Kiselev, Yury; Andersen, Sigve; Johannessen, Charles; Fjukstad, Bjørn; Olsen, Karina Standahl; Stenvold, Helge; Al-Saad, Samer; Dønnem, Tom; Richardsen, Elin; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      Lung cancer is the leading cause of cancer deaths. Novel predictive biomarkers are needed to improve treatment selection and more accurate prognostication. PAX6 is a transcription factor with a proposed tumour suppressor function. Immunohistochemical staining was performed on tissue microarrays from 335 non-small cell lung cancer (NSCLC) patients for PAX6. Multivariate analyses of clinico-pathological ...
