MetabolomicsRibosomal mistranslation leads to silencing of the unfolded protein response and increased mitochondrial biogenesis

Translation fidelity is the limiting factor in the accuracy of gene expression. With an estimated frequency of 10-4, errors in mRNA decoding occur in a mostly stochastic manner. Little is known about the response of higher eukaryotes to chronic loss of ribosomal accuracy as per an increase in the...

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.

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...

MetabolomicsA multi-omics dataset of heat-shock response in the yeast RNA binding protein Mip6 (NMR assay)

Gene expression is a biological process regulated at different molecular levels, including chromatin accessibility, transcription, and RNA maturation and transport. In addition, these regulatory mechanisms have strong links with cellular metabolism. Here we present a multi-omics dataset that capt...

MetabolomicsIdentification of the modifications in artificial E. coli rRNAs
Ribosome biogenesis is pivotal in the self-replication of life. In Escherichia coli, three ribosomal RNAs and 54 ribosomal proteins are synthesized and subjected to cooperative hierarchical assembly facilitated by numerous accessory factors. Realizing ribosome biogenesis in vitro is a critical miles...

GenomicsDeconvolution ChIP-seq profiling of UBF and RPA194 in K562 cells to identify analogous enhancer structures on mouse and human ribosomal RNA genes
The combination of Chromatin Immunoprecipitation and Massively Parallel Sequencing, or ChIP-Seq, has greatly advanced our genome-wide understanding of chromatin and enhancer structures. However, its resolution at any given genetic locus is limited by several factors. In applying ChIP-Seq to study th...

TranscriptomicsCircular non-coding RNA ANRIL modulates ribosomal RNA maturation and atherosclerosis in humans.
Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their role in human health and disease remains obscure. Here, we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of atherosclerotic cardiovascular disease on chromosome ...

TranscriptomicsTranscription profiling of S. cerevisiae ribosomal protein knockouts
Duplicated genes escape gene loss by conferring a dosage benefit or evolving diverged functions. The yeast Saccharomyces cerevisiae contains many duplicated genes encoding ribosomal proteins. Prior studies have suggested that these duplicated proteins are functionally redundant and affect cellular...

TranscriptomicsRibosomal Protein Gene Deletions in Diamond Blackfan Anemia
Diamond Blackfan anemia is a congenital bone marrow failure syndrome characterized by hypoproliferative anemia, often with associated physical abnormalities. Perturbations of the ribosome appear critically important to the development of DBA, as alterations in 9 different ribosomal protein genes ha...

ProteomicsLC-MS/MS analysis of human long ribosomal RNA
The field of epitranscriptomics is growing in importance, with chemical modification of RNA being associated with a wide variety of biological phenomena. Mass spectrometry (MS) enables the identification of modified RNA residues within their sequence contexts, by using analogous approaches to shotgu...
