Comparative analysis of RNA families reveals distinct repertoires for each domain of life. [PDF]

open access: yesPLoS Computational Biology, 2012
The RNA world hypothesis, that RNA genomes and catalysts preceded DNA genomes and genetically-encoded protein catalysts, has been central to models for the early evolution of life on Earth.

Transfer RNA and Origins of RNA Interference [PDF]

open access: yesFrontiers in Molecular Biosciences, 2021
Almost 30 years ago the first microRNA (miRNA) was detected (Lee et al., 1993), later put in mechanistical context by the discovery of the RNA interference (RNAi) and RNA-induced silencing complex (RISC). miRNA is the variable RISC element (guide) that recognizes messenger RNA (mRNA) targets in the RNAi process facilitated by Argonaute (Ago) proteins ...

A novel mistranslating tRNA model in Drosophila melanogaster has diverse, sexually dimorphic effects [PDF]

open access: yesG3: Genes, Genomes, Genetics, 2022
Transfer RNAs (tRNAs) are the adaptor molecules required for reading the genetic code and producing proteins. Transfer RNA variants can lead to genome-wide mistranslation, the misincorporation of amino acids not specified by the standard genetic code ...

A CRISPR-Cas9-based reporter system for single-cell detection of extracellular vesicle-mediated functional transfer of RNA

open access: yesNature Communications, 2020
Extracellular vesicles (EV) facilitate intercellular transfer of biological material including RNA, but the regulatory mechanisms for their formation and transfer are incompletely known.

Transfer RNA and human disease [PDF]

open access: yesFrontiers in Genetics, 2014
Pathological mutations in tRNA genes and tRNA processing enzymes are numerous and result in very complicated clinical phenotypes. Mitochondrial tRNA (mt-tRNA) genes are hotspots for pathological mutations and over 200 mt-tRNA mutations have been linked ...

Transfer RNA-derived small RNAs in the cancer transcriptome [PDF]

open access: yesPflügers Archiv: European Journal of Physiology, 2016
The cellular lifetime includes stages such as differentiation, proliferation, division, senescence and apoptosis.These stages are driven by a strictly ordered process of transcription dynamics.

Prebiotic chiral transfer from self-aminoacylating ribozymes may favor either handedness [PDF]

open access: yesNature Communications
Modern life is essentially homochiral, containing D-sugars in nucleic acid backbones and L-amino acids in proteins. Since coded proteins are theorized to have developed from a prebiotic RNA World, the homochirality of L-amino acids observed in all known ...

Transfer RNA Comes of Age [PDF]

open access: yesRNA, 2015
The year the journal RNA was founded was slated by some in scientific publishing to be the year that one particular type of RNA\u27s run in the spotlight would end.

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 ...

Small RNA-based feedforward loop with AND-gate logic regulates extrachromosomal DNA transfer in Salmonella [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2015
Horizontal gene transfer via plasmid conjugation is a major driving force in microbial evolution but constitutes a complex process that requires synchronization with the physiological state of the host bacteria.
