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.

Cross-site comparison of ribosomal depletion kits for Illumina RNAseq library construction

open access: yesBMC Genomics, 2018
Background Ribosomal RNA (rRNA) comprises at least 90% of total RNA extracted from mammalian tissue or cell line samples. Informative transcriptional profiling using massively parallel sequencing technologies requires either enrichment of mature poly ...

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.

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA [PDF]

open access: yes, 2010
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Ribosomal history reveals origins of modern protein synthesis. [PDF]

open access: yesPLoS ONE, 2012
The origin and evolution of the ribosome is central to our understanding of the cellular world. Most hypotheses posit that the ribosome originated in the peptidyl transferase center of the large ribosomal subunit.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Protocol dependence of sequencing-based gene expression measurements. [PDF]

open access: yesPLoS ONE, 2011
RNA Seq provides unparalleled levels of information about the transcriptome including precise expression levels over a wide dynamic range. It is essential to understand how technical variation impacts the quality and interpretability of results, how ...

RNA‐guided nucleotide modification of ribosomal and non‐ribosomal RNAs in Archaea [PDF]

open access: yesMolecular Microbiology, 2004
SummaryArchaea use ribonucleoprotein (RNP) machines similar to those found in the eukaryotic nucleolus to methylate ribose residues in nascent ribosomal RNA. The archaeal complex required for this 2′‐O‐ribose‐methylation consists of the C/D box sRNA guide and three proteins, the core RNA‐binding aL7a protein, the aNop56 protein and the ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.
