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.

Horizontal transfer between loose compartments stabilizes replication of fragmented ribozymes

open access: yes, 2019
The emergence of replicases that can replicate themselves is a central issue in the origin of life. Recent experiments suggest that such replicases can be realized if an RNA polymerase ribozyme is divided into fragments short enough to be replicable by ...

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.

Genome-wide profiling of uncapped mRNA [PDF]

open access: yes, 2012
Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...

T7 RNA polymerase‐driven inducible cell lysis for DNA transfer from Escherichia coli to Bacillus subtilis

open access: yesMicrobial Biotechnology, 2017
Summary The majority of the good DNA editing techniques have been developed in Escherichia coli; however, Bacillus subtilis is better host for a plethora of synthetic biology and biotechnology applications. Reliable and efficient systems for the transfer

Charging State Analysis of Transfer RNA from an α-proteobacterium

open access: yesBio-Protocol, 2020
Transfer RNA (tRNA) is an essential link between the genetic code and proteins. During the process of translation, tRNA is charged with its cognate amino acid and delivers it to the ribosome, thus serving as a substrate of protein synthesis.

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.

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 ...

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

open access: yesMolecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

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.
