Ribosomes and ribosomal RNA as chaperones for folding of proteins

open access: yesFolding and Design, 1997
Provocative recent reports indicate that the large subunits of either prokaryotic or eukaryotic ribosomes have the capacity to promote refolding of denatured enzymes.Salt-washed Escherichia coli ribosomes are shown to promote refolding of denatured rhodanese.

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

RNA G-quadruplex structures control ribosomal protein production

open access: yesScientific Reports, 2021
Four-stranded G-quadruplex (G4) structures form from guanine-rich tracts, but the extent of their formation in cellular RNA and details of their role in RNA biology remain poorly defined.

The 3'-terminal sequence of Escherichia coli 16S ribosomal RNA: complementarity to nonsense triplets and ribosome binding sites.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1974
With a stepwise degradation and terminal labeling procedure the 3'-terminal sequence of E. coli 16S ribosomal RNA is shown to be Pyd-A-C-C-U-C-C-U-U-A(OH). It is suggested that this region of the RNA is able to interact with mRNA and that the 3'-terminal

RNA processing: Pocket guides to ribosomal RNA [PDF]

open access: yesCurrent Biology, 1997
The functional role of a recently identified class of small nucleolar (sno) RNAs has been elucidated: the 'box H/ACA' snoRNAs act as guide RNAs, specifying the position of evolutionarily conserved pseudouridines in ribosomal (r)RNA via an rRNA-snoRNA base-pairing interaction that forms a 'pseudouridine pocket'.

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

open access: yesMolecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

RNAlater facilitates remote sampling of aquaculture Atlantic salmon liver for proteomic analysis

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 578-586, December 2022., 2022
Graphical Abstract Proteomes of similar sizes were obtained in samples preserved by snap‐freezing or RNAlater. Proteins involved in transcriptional and translational machinery were affected in RNAlater stored samples. Abundance of published markers for heat and oxidative stress was not affected by snap‐freezing or RNAlater.

Long non-coding RNAs as a source of new peptides [PDF]

open access: yes, 2014
Deep transcriptome sequencing has revealed the existence of many transcripts that lack long or conserved open reading frames and which have been termed long non-coding RNAs (lncRNAs). Despite the existence of several well-characterized lncRNAs that play roles in the regulation of gene expression, the vast majority of them do not yet have a known ...

Methylation of Ribosomal RNA: A Mitochondrial Perspective

open access: yesFrontiers in Genetics, 2020
Ribosomal RNA (rRNA) from all organisms undergoes post-transcriptional modifications that increase the diversity of its composition and activity. In mitochondria, specialized mitochondrial ribosomes (mitoribosomes) are responsible for the synthesis of 13

Ribosomal RNA regulates chromosome clustering during mitosis

open access: yesCell Discovery, 2022
Noncoding RNAs are known to associate with mitotic chromosomes, but the identities and functions of chromosome-associated RNAs in mitosis remain elusive. Here, we show that rRNA species associate with condensed chromosomes during mitosis.
