Association between gastrointestinal complaints and psychopathology in patients with anorexia nervosa
Kessler, Ute; Rekkedal, Guro; Rø, Øyvind; Berentsen, Birgitte; Steinsvik, Elisabeth Kjelsvik; Lied, Gülen Arslan; Danielsen, Yngvild Sørebø (Journal article; Peer reviewed, 2020)Objective Gastrointestinal (GI) symptoms appear frequently in patients with anorexia nervosa (AN), but the associations between psychopathological, GI, and eating disorder (ED) symptoms remain unclear. This study aimed ... -
Gastrointestinal transit and contractility in diabetic constipation: A wireless motility capsule study on diabetes patients and healthy controls
Sangnes, Dag A.; Lundervold, Katarina; Bekkelund, Mattis; Volkmann, Hilde Løland Von; Berentsen, Birgitte; Gilja, Odd Helge; Dimcevski, Georg; Søfteland, Eirik (Journal article; Peer reviewed, 2021)Background: Diabetic constipation is traditionally attributed to slow colonic transit, despite limited evidence. More than half of patients find treatment unsatisfactory. To improve treatment, there is a need for better ... -
MicroRNA Regulation of the Synaptic Plasticity-Related Gene Arc
Wibrand, Karin; Pai, Balagopal; Siripornmongcolchai, Taweeporn; Bittins, Margarethe; Berentsen, Birgitte; Ofte, May Lillian; Weigel, Arwed; Skaftnesmo, Kai Ove; Bramham, Clive R. (Peer reviewed; Journal article, 2012-07-26)Expression of activity-regulated cytoskeleton associated protein (Arc) is crucial for diverse types of experience-dependent synaptic plasticity and long-term memory in mammals. However, the mechanisms governing Arc-specific ... -
NMDA receptor-dependent regulation of miRNA expression and association with Argonaute during LTP in vivo
Pai, Balagopal; Siripornmongcolchai, Taweeporn; Berentsen, Birgitte; Pakzad, Ashraf; Vieuille, Christel Marie; Pallesen, Ståle; Pajak, Maciej; Simpson, T. Ian; Armstrong, J. Douglas; Wibrand, Karin; Bramham, Clive R. (Peer reviewed; Journal article, 2014-01-13)microRNAs (miRNAs) are major regulators of protein synthesis in the brain. A major goal is to identify changes in miRNA expression underlying protein synthesis-dependent forms of synaptic plasticity such as long-term ... -
The RNA-Binding Protein hnRNP K Mediates the Effect of BDNF on Dendritic mRNA Metabolism and Regulates Synaptic NMDA Receptors in Hippocampal Neurons
Leal, Graciano; Comprido, Diogo; de Luca, Pasqualino; Morais, Eduardo; Rodrigues, Luís; Mele, Miranda; Santos, Ana R.; Costa, Rui O.; Pinto, Maria Joana; Patil, Sudarshan; Berentsen, Birgitte; Afonso, Pedro; Carreto, Laura; Li, Ka Wan; Pinheiro, Paulo; Almeida, Ramiro D.; Santos, Manuel A. S.; Bramham, Clive R.; Duarte, Carlos B. (Peer reviewed; Journal article, 2017-11)Brain-derived neurotrophic factor (BDNF) is an important mediator of long-term synaptic potentiation (LTP) in the hippocampus. The local effects of BDNF depend on the activation of translation activity, which requires the ... -
Study protocol of the Bergen brain-gut-microbiota-axis study: A prospective case-report characterization and dietary intervention study to evaluate the effects of microbiota alterations on cognition and anatomical and functional brain connectivity in patients with irritable bowel syndrome
Berentsen, Birgitte; Nagaraja, Bharath Halandur; Teige, Erica Persson; Lied, Gülen Arslan; Lundervold, Astri; Lundervold, Katarina; Steinsvik, Elisabeth Kjelsvik; Hillestad, Eline Margrete Randulff; Valeur, Jørgen; Brønstad, Ingeborg; Gilja, Odd Helge; Osnes, Berge; Hatlebakk, Jan Gunnar; Haász, Judit; Labus, Jennifer; Gupta, Arpana; Mayer, Emeran; Benitez-Páez, Alfonso; Sanz, Yolanda; Lundervold, Arvid; Hausken, Trygve (Journal article; Peer reviewed, 2020-09)Introduction: Irritable bowel syndrome (IBS) is a common clinical label for medically unexplained gastrointestinal (GI) symptoms, recently described as a disturbance of the brain-gut-microbiota (BGM) axis. To gain a ...
