Combined in situ hybridization and immunohistochemistry on archival tissues reveals stromal microRNA-204 as prognostic biomarker for oral squamous cell carcinoma
Rajthala, Saroj; Dongre, Harsh; Parajuli, Himalaya; Min, Anjie; Nginamau, Elisabeth Sivy; Kvalheim, Arild; Lybak, Stein; Sapkota, Dipak; Johannessen, Anne Christine; Costea, Daniela Elena (Journal article; Peer reviewed, 2021)Micro-RNAs (miRs) are emerging as important players in carcinogenesis. Their stromal expression has been less investigated in part due to lack of methods to accurately differentiate between tumor compartments. This study ... -
Establishment of a bioluminescence model for microenvironmentally induced oral carcinogenesis with implications for screening bioengineered scaffolds.
Suliman, Salwa; Parajuli, Himalaya; Sun, Yang; Johannessen, Anne Christine; Finne-Wistrand, Anna; McCormack, Emmet; Mustafa, Kamal Babikeir Eln; Costea, Daniela Elena (Peer reviewed; Journal article, 2015)Background: Microenvironmental cues play a major role in head and neck cancer. Biodegradable scaffolds used for bone regeneration might also act as stimulative cues for head and neck cancer. The purpose of this study was ... -
Integrin a11 is overexpressed by tumour stroma of head and neck squamous cell carcinoma and correlates positively with alpha smooth muscle actin expression
Parajuli, Himalaya; Teh, Muy-Teck; Abrahamsen, Siren; Christoffersen, Ingeborg Monge; Neppelberg, Evelyn; Lybak, Stein; Osman, Tarig Al-Hadi; Johannessen, Anne Christine; Gullberg, Donald; Skarstein, Kathrine; Costea, Daniela Elena (Peer reviewed; Journal article, 2017-04)BACKGROUND: Cancer-associated fibroblasts (CAFs) were shown to be important for tumour progression in head and neck squamous cell carcinomas (HNSCCs). Their heterogeneity and lack of specific markers is increasingly ... -
The Low Affinity Nerve Growth Factor Receptor p75NTR Identifies a Transient Stem Cell-Like State in Oral Squamous Cell Carcinoma Cells
Osman, Tarig Al-Hadi; Costea, Daniela Elena; Parajuli, Himalaya; Sapkota, Dipak; Johannessen, Anne Christine; Ahmed, Israa A. H. (Peer reviewed; Journal article, 2014-09-12)Background Although several markers have been used for enrichment of cells with stem cell-like properties in oral squamous cell carcinoma (OSCC), isolation of a pure subpopulation is still a challenging task. Normal oral ... -
MicroRNA-138 abates fibroblast motility with effect on invasion of adjacent cancer cells
Rajthala, Saroj; Parajuli, Himalaya; Dongre, Harsh Nitin; Ljøkjel, Borghild; Hoven, Kristin Marie; Kvalheim, Arild; Lybak, Stein; Neppelberg, Evelyn; Sapkota, Dipak; Johannessen, Anne Christine; Costea, Daniela Elena (Journal article; Peer reviewed, 2022-03-17)Background: Recent studies have shown aberrant expression of micro-RNAs in cancer-associated fibroblasts (CAFs). This study aimed to investigate miR-138 dysregulation in CAFs in oral squamous cell carcinoma (OSCC) and its ... -
Nanodiamond modified copolymer scaffolds affects tumour progression of early neoplastic oral keratinocytes
Suliman, Salwa; Mustafa, Kamal Babikeir Eln; Krueger, Anke; Steinmüller-Nethl, Doris; Finne-Wistrand, Anna; Osdal, Tereza; Osman, Amani Hamza Ali; Sun, Yang; Parajuli, Himalaya; Waag, Thilo; Nickel, Joachim; Johannessen, Anne Christine; McCormack, Emmet; Costea, Daniela Elena (Peer reviewed; Journal article, 2016-07)This study aimed to evaluate the tumorigenic potential of functionalising poly(LLA-co-CL) scaffolds. The copolymer scaffolds were functionalised with nanodiamonds (nDP) or with nDP and physisorbed BMP-2 (nDP-PHY) to enhance ... -
Profiling and functional analysis of microRNA deregulation in cancer-associated fibroblasts in oral squamous cell carcinoma depicts an anti-invasive role of microRNA-204 via regulation of their motility
Rajthala, Saroj; Min, Anjie; Parajuli, Himalaya; Debnath, Kala Chand; Ljøkjel, Borghild; Hoven, Kristin Marie; Kvalheim, Arild; Lybak, Stein; Neppelberg, Evelyn; Vintermyr, Olav Karsten; Johannessen, Anne Christine; Sapkota, Dipak; Costea, Daniela Elena (Journal article; Peer reviewed, 2021-11-04)Background: Knowledge on the role of miR changes in tumor stroma for cancer progression is limited. This study aimed to investigate the role of miR dysregulation in cancer-associated fibroblasts (CAFs) in oral squamous ... -
Role of integrin α11 in oral carcinogenesis. In vitro and in vivo studies
Parajuli, Himalaya (Doctoral thesis, 2016-04-29)Cancer research has provided evidence for several advanced and better ways of treatment, helping the community for a better living. Nevertheless, for head and neck cancer there is still a long way to go for achieving an ... -
S100A16 promotes differentiation and contributes to a less aggressive tumor phenotype in oral squamous cell carcinoma
Sapkota, Dipak; Bruland, Ove; Parajuli, Himalaya; Osman, Tarig Al-Hadi; Teh, Muy-Teck; Johannessen, Anne Christine; Costea, Daniela Elena (Peer reviewed; Journal article, 2015-09-09)Background: Altered expression of S100A16 has been reported in human cancers, but its biological role in tumorigenesis is not fully understood. This study aimed to investigate the clinical significance and functional role ...
