A randomized double blind comparison of short-term duodenally administrated whale and seal blubber oils in patients with inflammatory bowel disease and joint pain
(Peer reviewed; Journal article, 2009)Compared with soy oil, 10 days treatment with seal oil (SO), 10 mL×3 daily, self-administrated through a nasoduodenal feeding tube, relieves joint pain in patients with inflammatory bowel disease (IBD). This randomized, ... -
Rapid adherence to collagen IV enriches for tumour initiating cells in oral cancer.
(Peer reviewed; Journal article, 2014-12)Background: Although several approaches for identification and isolation of carcinoma cells with tumour initiating properties have been established, enrichment of a population of pure and viable tumour-initiating cells ... -
Raptor-Mediated Proteasomal Degradation of Deamidated 4E-BP2 Regulates Postnatal Neuronal Translation and NF-κB Activity
(Peer reviewed; Journal article, 2019)The translation initiation repressor 4E-BP2 is deamidated in the brain on asparagines N99/N102 during early postnatal brain development. This post-translational modification enhances 4E-BP2 association with Raptor, a central ... -
A rat model of radiation injury in the mandibular area
(Peer reviewed; Journal article, 2015-06-09)Background Radiation technology focuses on delivering the radiation as precisely as possible to the tumor, nonetheless both acute and long-term damage to surrounding normal tissue may develop. Injuries to the surrounding ... -
Reactive oxygen species exert opposite effects on Tyr23 phosphorylation of the nuclear and cortical pools of Annexin A2
(Peer reviewed; Journal article, 2015-01-15)Annexin A2 (AnxA2) is a multi-functional and -compartmental protein whose subcellular localisation and functions are tightly regulated by its post-translational modifications. AnxA2 and its Tyr23-phosphorylated form ... -
Reduced expression of proteolipid protein 2 increases ER stress-induced apoptosis and autophagy in glioblastoma.
(Peer reviewed; Journal article, 2019-11-28)Proteolipid protein 2 (PLP2) is an integral ion channel membrane protein of the endoplasmic reticulum. The protein has been shown to be highly expressed in many cancer types, but its importance in glioma progression is ... -
Reduced Granulation Tissue and Wound Strength in the Absence of α11β1 Integrin
(Peer reviewed; Journal article, 2015-12-08)Previous wound healing studies have failed to define a role for either α1β1 or α2β1 integrin in fibroblast-mediated wound contraction, suggesting the involvement of another collagen receptor in this process. Our previous ... -
Reduced Joint Pain after Short-term Duodenal Administration of Seal Oil in Patients with Inflammatory Bowel Disease: Comparison with Soy Oil
(Peer reviewed; Journal article, 2004)Background: Rheumatic joint pain is a common extraintestinal complication of inflammatory bowel disease (IBD). Because the high ratio of n-6 to n-3 fatty acids (FAs) of the Western diet might promote rheumatic disorders, ... -
Regulation and function of tumor suppressor p53 isoforms beta and gamma in Acute Myeloid Leukemia
(Master thesis, 2013-06-01)Research has proposed that the C-terminal truncated p53 isoforms beta and gamma enhance chemosensitivity in p53(null) cancer cell lines. Their high expression in acute myeloid leukemia (AML) patients correlates positively ... -
Regulation and quantification of cellular mitochondrial morphology and content
(Peer reviewed; Journal article, 2014)Mitochondria play a key role in signal transduction, redox homeostasis and cell survival, which extends far beyond their classical functioning in ATP production and energy metabolism. In living cells, mitochondrial content ... -
Regulation of CDKN2B expression by interaction of Arnt with Miz-1 - a basis for functional integration between the HIF and Myc gene regulatory pathways
(Peer reviewed; Journal article, 2014-03-11)Background: Hypoxia- and Myc-dependent transcriptional regulatory pathways are frequently deregulated in cancer cells. These pathways converge in many cellular responses, but the underlying molecular mechanisms are unclear. ... -
Regulation of tyrosine hydroxylase is preserved across different homo- and heterodimeric 14-3-3 proteins
(Peer reviewed; Journal article, 2016-05)Tyrosine hydroxylase (TH) is regulated by members of the 14-3-3 protein family. However, knowledge about the variation between 14-3-3 proteins in their regulation of TH is still limited. We examined the binding, effects ... -
Regulatory Peptides from Chromogranin A and Secretogranin II
(Peer reviewed; Journal article, 2010)This commentary is focusing on novel aspects on the secreted CgA- and SgII-derived peptides, vasostatin-I (bovine and human CgA1–76, VS-I), WE-14 (CgA316–329), catestatin (bovine CgA344–366, human CgA352–372, Cts) and the ... -
Regulatory post-translational modifications and protein-protein interactions involved in function and proteostasis of aromatic amino acid hydroxylases
(Doctoral thesis, 2021-09-16)The non-heme iron and (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) dependent aromatic amino acid hydroxylases (AAAHs) family of enzymes include phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), and tryptophan ... -
The Regulatory Subunit of PKA-I Remains Partially Structured and Undergoes b-Aggregation upon Thermal Denaturation
(Peer reviewed; Journal article, 2011-03-04)Background: The regulatory subunit (R) of cAMP-dependent protein kinase (PKA) is a modular flexible protein that responds with large conformational changes to the binding of the effector cAMP. Considering its highly dynamic ... -
Release of tensile strain on engineered human tendon tissue disturbs cell adhesions, changes matrix architecture, and induces an inflammatory phenotype
(Peer reviewed; Journal article, 2014-01-21)Mechanical loading of tendon cells results in an upregulation of mechanotransduction signaling pathways, cell-matrix adhesion and collagen synthesis, but whether unloading removes these responses is unclear. We investigated ... -
Relevance of Electrostatics for the Interaction of Tyrosine Hydroxylase with Porous Silicon Nanoparticles
