Elevated microsatellite alterations at selected tetranucleotides (EMAST) is not attributed to MSH3 loss in stage I-III colon cancer: An automated, digitalized assessment by immunohistochemistry of whole slides and hot spots
Watson, Martin M; Lea, Dordi; Hagland, Hanne Røland; Søreide, Kjetil (Peer reviewed; Journal article, 2019-12)INTRODUCTION: EMAST is a poorly understood form of microsatellite instability (MSI) in colorectal cancer (CRC) for which loss of MSH3 has been proposed as the underlying mechanism, based on experimental studies. We aimed ... -
Elevated microsatellite alterations at selected tetranucleotides in early-stage colorectal cancers with and without high-frequency microsatellite instability: same, same but different?
Watson, Martin M; Lea, Dordi; Rewcastle, Emma; Hagland, Hanne Røland; Søreide, Kjetil (Peer reviewed; Journal article, 2016-07)Microsatellite instability (MSI) is associated with better prognosis in colorectal cancer (CRC). Elevated microsatellite alterations at selected tetranucleotides (EMAST) is a less-understood form of MSI. Here, we aim to ... -
Graphene-based phenformin carriers for cancer cell treatment: a comparative study between oxidized and pegylated pristine graphene in human cells and zebrafish
Alhourani, Abdelnour; Førde, Jan-Lukas; Nasrollahzadeh, Mojdeh; Eichacker, Lutz Andreas; Herfindal, Lars; Hagland, Hanne Røland (Journal article; Peer reviewed, 2022)Graphene is an attractive choice for the development of an effective drug carrier in cancer treatment due to its high adsorption area and pH-responsive drug affinity. In combination with the highly potent metabolic drug ... -
Improved pH-Responsive Release of Phenformin from Low-Defect Graphene Compared to Graphene Oxide
Alhourani, Abdelnour; Førde, Jan-Lukas; Eichacker, Lutz Andreas; Herfindal, Lars; Hagland, Hanne Røland (Journal article; Peer reviewed, 2021)Graphene-based drug carriers provide a promising addition to current cancer drug delivery options. Increased accessibility of high-quality graphene made by plasma-enhanced chemical vapor deposition (PE-CVD) makes it an ... -
Metabolic flux analysis of 3D spheroids reveals significant differences in glucose metabolism from matched 2D cultures of colorectal cancer and pancreatic ductal adenocarcinoma cell lines
Tidwell, Tia R.; Røsland, Gro Vatne; Tronstad, Karl Johan; Søreide, Kjetil; Hagland, Hanne Røland (Journal article; Peer reviewed, 2022)Background Most in vitro cancer cell experiments have been performed using 2D models. However, 3D spheroid cultures are increasingly favored for being more representative of in vivo tumor conditions. To overcome the ... -
Prevalence of PD‑L1 expression is associated with EMAST, density of peritumoral T‑cells and recurrence‑free survival in operable non‑metastatic colorectal cancer
Watson, Martin Matthew Christian; Lea, Dordi; Gudlaugsson, Einar; Skaland, Ivar; Hagland, Hanne Røland; Søreide, Kjetil (Journal article; Peer reviewed, 2020-04-20)Introduction Microsatellite instability (MSI) predict response to anti-PD1 immunotherapy in colorectal cancer (CRC). CRCs with MSI have higher infiltration of immune cells related to a better survival. Elevated Microsatellite ... -
A template to quantify the location and density of CD3 + and CD8 + tumor-infiltrating lymphocytes in colon cancer by digital pathology on whole slides for an objective, standardized immune score assessment
Lea, Dordi; Watson, Martin Matthew Christian; Skaland, Ivar; Hagland, Hanne Røland; Lillesand, Melinda; Gudlaugsson, Einar; Søreide, Kjetil (Journal article; Peer reviewed, 2021)Background: In colon cancer, the location and density of tumor-infiltrating lymphocytes (TILs) can classify patients into low and high-risk groups for prognostication. While a commercially available ‘Immunoscore®’ exists, ...
