(Cold Spring Harbor Laboratory, 2019-01-28)Circular RNAs (circRNAs) are a class of RNAs that is under increasing scrutiny, although their functional roles are debated. We analyzed RNA-seq data of 348 primary breast cancers and developed a method to identify circRNAs that does not rely on unmapped ... -
(Oxford University Press (OUP), 2019-03-20)Genomes are dynamic biological units, with processes of gene duplication and loss triggering evolutionary novelty. The mammalian skin provides a remarkable case study on the occurrence of adaptive morphological innovations. Skin sebaceous glands (SGs), ...

(Impact Journals, LLC, 2019-07-23)Estrogen receptor-positive breast cancer is subdivided into subtypes LuminalA and LuminalB, based on different expression patterns. MicroRNA-190b has been reported to be up-regulated in estrogen receptor-positive breast cancers. In this study we aimed ...

(University of Iceland, School of Health Sciences, Faculty of Medicine, 2020-12-02)Epithelial to mesenchymal transition (EMT) is a developmental trait that is hijacked in some disease conditions such as fibrosis and cancer. In cancer, EMT has been linked to increased invasion and metastasis, and is generally associated with a poor ...
-
(MDPI AG, 2020-07-12)Dibothriocephalus dendriticus is one of the causative agents of the fish-borne zoonosis diphyllobothriosis. Polymorphic microsatellite markers were originally developed for future genetic studies using microsatellite library screening and next-generation ...
-
(Springer, 2024-02-16)More than 1600 human transcription factors orchestrate the transcriptional machinery to control gene expression and cell fate. Their function is conveyed through intrinsically disordered regions (IDRs) containing activation or repression domains but ...
-
(Wiley, 2018-08-13)The investigation of the structure and conformational dynamics of biomolecules under physiological conditions is challenging for structural biology. Although pulsed electron paramagnetic resonance (like PELDOR) techniques provide long‐range distance ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-05)The DNA damage response is crucial to maintaining the integrity of DNA and the health of a cell. Unrepaired lesions within the DNA can lead to genomic instability and potentially aid in the formation of diseases such as cancer. Some cancers possess ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2024-12-06)Epitranscriptomics refers to post-transcriptional regulation of gene expression via RNA modifications, which can affect the function and structure of RNAs but do not entail any changes to the ribonucleotide sequence. RNA modifications are found on all ...
-
(Frontiers Media SA, 2020-06-16)Epithelial-to-mesenchymal transition (EMT) and its reversed process mesenchymal-to-epithelial transition (MET) play a critical role in epithelial plasticity during development and cancer progression. Among important regulators of these cellular processes ...
-
(Royal Society of Chemistry (RSC), 2016)The cocaine aptamer is a DNA three-way junction that binds cocaine at its helical junction. We studied the global conformation and overall flexibility of the aptamer in the absence and presence of cocaine by pulsed electron-electron double resonance ...
-
(Springer Science and Business Media LLC, 2019-01-24)Genome-wide association studies (GWAS) of quantitative electrocardiographic (ECG) traits in large consortia have identified more than 130 loci associated with QT interval, QRS duration, PR interval, and heart rate (RR interval). In the current study, ...
-
(Springer Science and Business Media LLC, 2019-11-27)Analysis of sequence diversity in the human genome is fundamental for genetic studies. Structural variants (SVs) are frequently omitted in sequence analysis studies, although each has a relatively large impact on the genome. Here, we present GraphTyper2, ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2019-06)A fundamental requisite for genetic studies is an accurate determination of sequence variation. While human genome sequence diversity is increasingly well characterized, there is a need for efficient ways to utilize this knowledge in sequence analysis. ...
-
(Oxford University Press (OUP), 2019-11-28)Pulsed electron paramagnetic resonance (EPR) experiments, among them most prominently pulsed electron-electron double resonance experiments (PELDOR/DEER), resolve the conformational dynamics of nucleic acids with high resolution. The wide application ...
-
(Springer Science and Business Media LLC, 2019-06-11)Epigenetic processes, including DNA methylation (DNAm), are among the mechanisms allowing integration of genetic and environmental factors to shape cellular function. While many studies have investigated either environmental or genetic contributions ...
-
(Royal Society of Chemistry (RSC), 2018)In the first example of site-directed spin-labeling of unmodified RNA, a pyrrolidine-nitroxide derivative of tetramethylrosamine (TMR) was shown to bind with high affinity to the malachite green (MG) aptamer, as determined by continuous-wave (CW) ...
-
(Háskóli Íslands, Heilbrigðisvísindasvið, Læknadeild, 2024-11)Genome instability is a common feature of most cancer types. DNA damage is an important source of genome instability wherein DNA double strand breaks (DSBs) are particularly genotoxic as both strands of the DNA molecule are severed, risking loss ...
-
(Oxford University Press (OUP), 2018-07-24)DNA damage assays have various limitations in types of lesions detected, sensitivity, specificity and samples that can be analyzed. The Northern Lights Assay (NLA) is based on 2D Strandness-Dependent Electrophoresis (2D-SDE), a technique that separates ...
-
(Wiley, 2020-09-11)Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 ...
