Molecular modeling study of the testosterone metabolizing enzyme UDP-glucuronosyltransferase 2B17
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-20)The dominant sex hormone testosterone is mainly metabolized by liver enzymes belonging to the uridine-diphospho (UDP) glucuronosyltransferase (UGT) family. These enzymes are the main phase II enzymes, and they have an important role in the detoxification of endogenous and exogenous compounds in humans. The aim of the present study was to improve the understanding of the binding properties of UGT2B17. ... -

Tumour cells express functional lymphatic endothelium-specific hyaluronan receptor in vitro and in vivo: Lymphatic mimicry promotes oral oncogenesis?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-05)Lymphatic metastasis represents the main route of tumour cell dissemination in oral squamous cell carcinoma (OSCC). Yet, there are no FDA-approved therapeutics targeting cancer-related lymphangiogenesis to date. The lymphatic vessel endothelial hyaluronic acid receptor 1 (LYVE-1), a specific lymphatic marker, is associated with poor survival in OSCC patients. In this study, we present a potential ... -
The effect of interleukin-17F on vasculogenic mimicry in oral tongue squamous cell carcinoma
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-20)Oral tongue squamous cell carcinoma (OTSCC) is one of the most common cancers worldwide and is characterized by early metastasis and poor prognosis. Recently, we reported that extracellular interleukin-17F (IL-17F) correlates with better disease-specific survival in OTSCC patients and has promising anticancer effects in vitro. Vasculogenic mimicry (VM) is the formation of an alternative vasculogenic ... -
Platelet alloimmunization is associated with low grade chronic histiocytic intervillositis - A new link to a rare placental lesion?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-23)<i>Introduction</i> - Maternal alloimmunization against human platelet antigen (HPA)-1a has been implied to mediate both reduced birth weight and chronic placental inflammation. Fetal growth restriction is associated with different types of chronic inflammation in the placenta, mainly chronic histiocytic intervillositis and chronic villitis. The aim of this prospective study was to do a systematic ... -
Detection of phenotype-specific therapeutic vulnerabilities in breast cells using a CRISPR loss-of-function screen
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)Cellular phenotype plasticity between the epithelial and mesenchymal states has been linked to metastasis and heterogeneous responses to cancer therapy, and remains a challenge for the treatment of triple-negative breast cancer (TNBC). Here, we used isogenic human breast epithelial cell lines, D492 and D492M, representing the epithelial and mesenchymal phenotypes, respectively. We employed a CRISPR-Cas9 ... -
High expression of miR-17-5p in tumor epithelium is a predictor for poor prognosis for prostate cancer patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-05)MicroRNAs (miRs) are small non-coding RNA molecules, which are involved in the development of various malignancies, including prostate cancer (PCa). miR-17-5p is considered the most prominent member of the miR-17-92 cluster, with an essential regulatory function of fundamental cellular processes. In many malignancies, up-regulation of miR-17-5p is associated with worse outcome. In PCa, miR-17-5p has ... -
Treatment of cardiovascular dysfunction with PDE5-inhibitors - temperature dependent effects on transport and metabolism of cAMP and cGMP
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-30)<i>Introduction</i>: Cardiovascular dysfunction is a potentially lethal complication of hypothermia. Due to a knowledge gap, pharmacological interventions are not recommended at core temperatures below 30°C. Yet, further cooling is induced in surgical procedures and survival of accidental hypothermia is reported after rewarming from below 15°C, advocating a need for evidence-based treatment guidelines. ... -
Role of Virus-Induced Host Cell Epigenetic Changes in Cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)The tumor viruses human T-lymphotropic virus 1 (HTLV-1), hepatitis C virus (HCV), Merkel cell polyomavirus (MCPyV), high-risk human papillomaviruses (HR-HPVs), Epstein-Barr virus (EBV), Kaposi’s sarcoma-associated herpes virus (KSHV) and hepatitis B virus (HBV) account for approximately 15% of all human cancers. Although the oncoproteins of these tumor viruses display no sequence similarity to one ... -

Multiscale and Multimodal Optical Imaging of the Ultrastructure of Human Liver Biopsies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)The liver as the largest organ in the human body is composed of a complex macroscopic and microscopic architecture that supports its indispensable function to maintain physiological homeostasis. Optical imaging of the human liver is particularly challenging because of the need to cover length scales across 7 orders of magnitude (from the centimeter scale to the nanometer scale) in order to fully ... -
The prognostic effect of KRAS mutations in non-small cell lung carcinoma revisited: A norwegian multicentre study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)Background: due to emerging therapeutics targeting KRAS G12C and previous reports with conflicting results regarding the prognostic impact of KRAS and KRAS G12C in non-small cell lung cancer (NSCLC), we aimed to investigate the frequency of KRAS mutations and their associations with clinical characteristics and outcome. Since mutation subtypes have different preferences for downstream pathways, we ... -
Exploring Klebsiella pneumoniae in Healthy Poultry Reveals High Genetic Diversity, Good Biofilm-Forming Abilities and Higher Prevalence in Turkeys Than Broilers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-07)Klebsiella pneumoniae is a well-studied human pathogen for which antimicrobial resistant and hypervirulent clones have emerged globally. K. pneumoniae is also present in a variety of environmental niches, but currently there is a lack of knowledge on the occurrence and characteristics of K. pneumoniae from non-human sources. Certain environmental niches, e.g., animals, may be associated with high ... -
Reciprocal transactivation of Merkel cell polyomavirus and high-risk human papillomavirus promoter activities and increased expression of their oncoproteins
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-03)<i>Background</i> - Approximately 15% of human cancers are attributed to viruses. Numerous studies have shown that high-risk human polyomaviruses (HR-HPV) and Merkel cell polyomavirus (MCPyV) are two human tumor viruses associated with anogenetal and oropharyngeal cancers, and with Merkel cell carcinoma, respectively. MCPyV has been found in HR-HPV positive anogenetal and oropharyngeal tumors, ... -
Validation of Selected Head and Neck Cancer Prognostic Markers from the Pathology Atlas in an Oral Tongue Cancer Cohort
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-14)The Pathology Atlas is an open-access database that reports the prognostic value of protein-coding transcripts in 17 cancers, including head and neck cancer. However, cancers of the various head and neck anatomical sites are specific biological entities. Thus, the aim of the present study was to validate promising prognostic markers for head and neck cancer reported in the Pathology Atlas in oral ... -

Proteomic analyses identify major vault protein as a prognostic biomarker for fatal prostate cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-20)The demographic shift toward an older population will increase the number of prostate cancer cases. A challenge in the treatment of prostate cancer is to avoid undertreatment of patients at high risk of progression following curative treatment. These men can benefit from early salvage treatment. An explorative cohort consisting of tissue from 16 patients who underwent radical prostatectomy, and were ...
