RNA secondary structure prediction using an ensemble of two-dimensional deep neural networks and transfer learning

open access: yesNature Communications, 2019
The limited availability of high-resolution 3D RNA structures for model training limits RNA secondary structure prediction. Here, the authors overcome this challenge by pre-training a DNN on a large set of predicted RNA structures and using transfer ...

Complete chloroplast genome sequence of Chrysosplenium macrophyllum and Chrysosplenium flagelliferum (Saxifragaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete chloroplast genome of Chrysosplenium macrophyllum Oliv. and Chrysosplenium flagelliferum Fr. Schmidt. were reported in this study. The chloroplast genomes were 152,837 bp for C. macrophyllum and 151,679 bp for C. flagelliferum.

Structural organization of complexes of transfer RNAs with aminoacyl transfer RNA synthetases

open access: yesNucleic Acids Research, 1977
A variety of experimental data on synthetase-tRNA interactions are examined. Although these data previously had no direct explanation when viewed only in terms of the tRNA cloverleaf diagram, they can be rationalized according to a simple proposal that takes account of the three dimensional structure of tRNA.

Circulating tumor cells in metastatic breast cancer patients treated with immune checkpoint inhibitors – a biomarker analysis of the ALICE and ICON trials

open access: yesMolecular Oncology, EarlyView.
In this explorative biomarker analysis, we assessed serial sampling of circulating tumor cells (CTCs) with CellSearch in two randomized trials testing immune checkpoint inhibitors (ICIs) in metastatic breast cancer. Our data demonstrate a prognostic potential of CTCs, most apparent 4 weeks into ICI therapy.

Analysis of tRNA halves (tsRNAs) in serum from cattle challenged with bovine viral diarrhea virus

open access: yesGenetics and Molecular Biology
Acute infections of bovine viral diarrhea virus (BVDV) lead to a range of clinical presentations. Laboratory tests for detection depend on collection of samples during a short viremia. Acutely infected animals remain largely undiagnosed.

Complete mitochondrial genome of the coconut black-headed caterpillar Opisina arenosella (Lepidoptera: Gelechioidea: Xyloryctidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
In the present study, we determined the complete mitogenome of Opisina arenosella, the first for the family Xyloryctidae. This mitochondrial genome contains 15,389 bp, with an A + T content of 80.5% and consists of 13 protein-coding genes, 22 transfer ...

A comparative study of circulating tumor cell isolation and enumeration technologies in lung cancer

open access: yesMolecular Oncology, EarlyView.
Lung cancer cells were spiked into donor blood to evaluate the recovery rates of the following circulating tumor cell (CTC) enrichment technologies: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1, and Parsortix® Prototype systems. Each method's advantages and disadvantages are described.

N2-methylguanosine and N2, N2-dimethylguanosine in cytosolic and mitochondrial tRNAs

open access: yesFrontiers in RNA Research
Decoration of cellular RNAs with modified RNA nucleosides is an important layer of gene expression regulation. Throughout the transcriptome, RNA modifications influence the folding, stability and function of RNAs as well as their interactions with RNA ...

RNA Secondary Structures: Complex Statics and Glassy Dynamics [PDF]

open access: yesarXiv, 2007
Models for RNA secondary structures (the topology of folded RNA) without pseudo knots are disordered systems with a complex state-space below a critical temperature. Hence, a complex dynamical (glassy) behavior can be expected, when performing Monte Carlo simulation.

On‐treatment dynamics of circulating extracellular vesicles in the first‐line setting of patients with advanced non‐small cell lung cancer: the LEXOVE prospective study

open access: yesMolecular Oncology, EarlyView.
The LEXOVE prospective study evaluated plasma cell‐free extracellular vesicle (cfEV) dynamics using Bradford assay and dynamic light scattering in metastatic non‐small cell lung cancer patients undergoing first‐line treatments, correlating a ∆cfEV < 20% with improved median progression‐free survival in responders versus non‐responders.
