MetabolomicsElucidation of the epitranscriptomic RNA modification landscape of chikungunya virus

The genomes of positive-sense (+) single-stranded RNA (ssRNA) viruses are believed to be subjected to a wide range of RNA modifications. In this study, we focused on the chikungunya virus (CHIKV) as a model (+) ssRNA virus to study the landscape of viral RNA modification in infected human cells. ...

TranscriptomicsNascent-seq indicates widespread cotranscriptional RNA editing in Drosophila
The RNA editing enzyme ADAR chemically modifies adenosine (A) to inosine (I), which is interpreted by the ribosome as a guanosine. Here we assess cotranscriptional A-to-I editing in Drosophila, by isolating nascent RNA from adult fly heads and subjecting samples to high-throughput sequencing. There ...

TranscriptomicsADAR1-mediated A-to-I RNA editing is essential for erythropoiesis [RNA-seq]
Purpose: RNA editing by ADAR1 is essential for hematopoietic development. The goals of this study were firstly, to identify ADAR1-specific RNA-editing sites by indentifying A-to-I (G) RNA editing sites in wild type mice that were not edited or reduced in editing frequency in ADAR1 deficient murine e...

MetabolomicsRNA modification dynamics during Enterococcus faecalis OG1RF growth
Quantitative analysis of relative levels of RNA modifications in small (primarily tRNA) and large (primarily 16S/23S rRNA) RNAs isolated from Enterococcus faecalis OG1RF across a growth time course in BHI media.

TranscriptomicsThe dsRBP and inactive editor, ADR-1, utilizes dsRNA binding to regulate A-to-I RNA editing across the C. elegans transcriptome
Purpose: The purpose of this experiment is to expand the repertoire of C. elegans edited transcripts and identify the roles of ADR-1 as indirect regulator of editing and ADR-2 as the only active deaminase in vivo. Methods: Strand-specific RNA sequencing of wild-type and adr mutant worms, followed by...

MetabolomicsTranslational repression of viral RNA mediates arbovirus persistence in mosquitoes

Persistent infection of mosquito vectors is essential for the transmission of arboviruses, yet how these viruses produce sufficient progeny without compromising host cell fitness remains unclear. Arbovirus genomes exhibit suboptimal codon usage for both human and mosquito hosts, raising questions...

TranscriptomicsEvolutionary and ontogenetic changes in RNA editing in human, chimpanzee and macaque brains
we used RNA-Seq to quantify the RNA editing level at more than 8,000 previously annotated exonic A-to-I RNA editing sites in two brain regions - prefrontal cortex and cerebellum - of humans, chimpanzees and rhesus macaques. We observed substantial conservation of RNA editing levels between the brain...

TranscriptomicsAlu sequences in undifferentiated human embryonic stem cells display high levels of A-to-I RNA editing
Adenosine to Inosine (A-to-I) RNA editing is a site-specific modification of RNA transcripts, catalyzed by members of the ADAR (Adenosine Deaminase Acting on RNA) protein family. RNA editing occurs in human RNA in thousands of different sites. Some of the sites are located in protein-coding regions ...

ProteomicsProteogenomics of adenosine-to-inosine RNA editing in fruit fly
This dataset is a part of a bigger work on RNA editing in D. melanogaster brain. We present Orbitrap spectra searched against a customized database of Drosophila proteome with introduction of variants provided by RNA editing. Three files reflect 3 technical replicates.
