    • Assessing new prognostic biomarkers in resected colon cancer patients 

      Selven, Hallgeir (Doctoral thesis; Doktorgradsavhandling, 2023-06-22)
      Colon cancer is a common malignancy. We retrospectively established a biobank including 452 patients operated for colon cancer stage I-III in Northern Norway in the period 1998-2007. Tissue microarrays (TMAs) containing tumor tissue from these patients were constructed, and subsequently biomarker expression assessed by digital pathology. By using in situ hybridization, we assessed the expression of ...

    • High Expression of IRS-1, RUNX3 and SMAD4 Are Positive Prognostic Factors in Stage I–III Colon Cancer 

      Selven, Hallgeir; Rasmussen Busund, Lill-Tove; Andersen, Sigve; Pedersen, Mona Irene; Lombardi, Ana Paola Giometti; Kilvær, Thomas Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-24)
      Colon cancer is a common malignancy and a major contributor to human morbidity and mortality. In this study, we explore the expression and prognostic impact of IRS-1, IRS-2, RUNx3, and SMAD4 in colon cancer. Furthermore, we elucidate their correlations with miRs 126, 17-5p, and 20a-5p, which are identified as potential regulators of these proteins. Tumor tissue from 452 patients operated for stage ...

    • High expression of microRNA‑126 relates to favorable prognosis for colon cancer patients 

      Selven, Hallgeir; Rasmussen Busund, Lill-Tove; Bremnes, Roy M.; Andersen, Sigve; Kilvær, Thomas Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-05)
      miR-126 has been identified both as a tumor suppressor and an oncogene in different types of cancer. The aim of this study was to investigate the prognostic impact of miR-126-expression in colon cancer patients. Tumor tissue from 452 patients operated for stage I–III colon cancer was retrospectively collected and tissue microarrays were constructed. miR-126 expression was evaluated by in situ ...

    • High expression of miR-17-5p and miR-20a-5p predicts favorable disease-specific survival in stage I-III colon cancer 

      Selven, Hallgeir; Kilvær, Thomas Karsten; Andersen, Sigve; Rasmussen Busund, Lill-Tove; Pedersen, Mona Irene; Lombardi, Ana Paola (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-30)
      In many types of cancer, microRNAs (miRs) are aberrantly expressed. The aim of this study was to explore the prognostic impact of miR-17-5p and miR-20a-5p in colon cancer. Tumor tissue from 452 stage I-III colon cancer patients was retrospectively collected and tissue microarrays constructed. miR-17-5p and miR-20a-5p expression was evaluated by in situ hybridization and analyzed using digital ...
