Epithelial PD-L1 expression at tumor front predicts overall survival in a cohort of oral squamous cell carcinomas from Sudan
Mohamed, Nuha Mohamed Gaafar; Osman, Tarig Al-Hadi; Elsheikh, Mariam; Alhaj Ahmed, Israa Abdul Rhman Hassaballah; Dongre, Harsh Nitin; Fromreide, Siren; Suleiman, Ahmed M.; Johannessen, Anne Christine; Nginamau, Elisabeth Sivy; Costea, Daniela Elena (Journal article; Peer reviewed, 2022)Background We recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active ... -
Establishment of a novel cancer cell line derived from vulvar carcinoma associated with lichen sclerosus exhibiting a fibroblast-dependent tumorigenic potential
Dongre, Harsh; Rana, Neha; Fromreide, Siren; Rajthala, Saroj; Engelsen, Ingeborg Bøe; Paradis, Justine; Gutkind, J. Silvio; Vintermyr, Olav Karsten; Johannessen, Anne Christine; Bjørge, Line; Costea, Daniela Elena (Journal article; Peer reviewed, 2020)Vulvar squamous cell carcinoma associated with lichen sclerosus (VLS-VSCC) are rare tumors but with higher recurrence and worse prognosis than other types of VSCC. Lack of experimental models has limited the search for ... -
Expression of NGAL-specific cells and mRNA levels correlate with inflammation in the salivary gland, and its overexpression in the saliva, of patients with primary Sjögren’s syndrome
Aqrawi, Lara Adnan; Jensen, Janicke Cecilie Liaaen; Fromreide, Siren; Galtung, Hilde Kanli; Skarstein, Kathrine (Journal article; Peer reviewed, 2020)Salivary gland involvement is a characteristic feature of primary Sjögren’s syndrome (pSS), where tissue destruction is mediated by infiltrating immune cells, and may be accompanied by the presence of adipose tissue. ... -
Geomicrobial characterisation of a 60 m long permafrost core, taken over a future CO2 storage site at Svalbard
Fromreide, Siren (Master thesis, 2014-09-11)In connection with a planned CO2 storage pilot project in the Arctic, a 60 m long permafrost core was drilled in Adventdalen, Svalbard, representing the poorly studied deep permafrost ecosystems. The on-shore drilling was ... -
Inflammatory Stratification in Primary Sjögren’s Syndrome Reveals Novel Immune Cell Alterations in Patients’ Minor Salivary Glands
Bharaj, Tamandeep Kaur; Aqrawi, Lara A.; Fromreide, Siren; Jonsson, Roland; Brun, Johan G.; Appel, Silke; Skarstein, Kathrine (Journal article; Peer reviewed, 2021)There is a critical need to deconvolute the heterogeneity displayed by the minor salivary glands of primary Sjögren’s syndrome (pSS) patients. This is challenging primarily because the disease etiology remains unknown. The ... -
The neuroprotective potential of mesenchymal stem cells from bone marrow and human exfoliated deciduous teeth in a murine model of demyelination
Kråkenes, Torbjørn; Wergeland, Stig; Al-Sharabi, Niyaz Abdulbaqi Abdulmajid; Mohamed-Ahmed, Samih Salah Eldin Mahgoub; Fromreide, Siren; Costea, Daniela Elena; Mustafa, Kamal Babikeir Elnour; Bø, Lars; Kvistad, Christopher Elnan (Journal article; Peer reviewed, 2023)Introduction Multiple sclerosis (MS) is characterized by chronic inflammation, demyelination, and axonal degeneration within the central nervous system (CNS), for which there is no current treatment available with the ... -
Targeted Next-Generation Sequencing of Cancer-Related Genes in a Norwegian Patient Cohort With Head and Neck Squamous Cell Carcinoma Reveals Novel Actionable Mutations and Correlations With Pathological Parameters
