28S rRNA sequences for Linguatula spp. [PDF]

open access: yesParasitol Res, 2022
Abstract Identification of specimens belonging to the genus Linguatula (Pentastomida) is relatively easy due to their unique morphology. However, differentiation between species of Linguatula can be challenging for several reasons, including considerable differences between different developmental stages of the parasite within and between species ...

N6-methyladenosine in 28S rRNA promotes oncogenic mRNA translation and tyrosine catabolism

open access: yesCell Reports
Summary: Aberrant N6-methyladenosine (m6A) modification on mRNA results in dysregulated mRNA translation and cancer progression; however, the role of m6A modification on rRNA remains unclear in cancers.

Mushroom DNA barcoding project: Sequencing a segment of the 28S rRNA gene. [PDF]

open access: yesBiochem Mol Biol Educ, 2020
AbstractDNA barcoding is an important molecular methodology for species identification that was developed over the last two decades and it should be covered in the biology bachelor curriculum. Here, we present an example of DNA barcoding by sequencing a segment of the 28S nuclear ribosomal large subunit rRNA gene of wild mushrooms and framing the ...

Ribosomal RNA (rRNA) sequences from 33 globally distributed mosquito species for improved metagenomics and species identification

open access: yeseLife, 2023
Total RNA sequencing (RNA-seq) is an important tool in the study of mosquitoes and the RNA viruses they vector as it allows assessment of both host and viral RNA in specimens. However, there are two main constraints.

Evolution of the R2 retrotransposon ribozyme and its self-cleavage site. [PDF]

open access: yesPLoS ONE, 2013
R2 is a non-long terminal repeat retrotransposon that inserts site-specifically in the tandem 28S rRNA genes of many animals. Previously, R2 RNA from various species of Drosophila was shown to self-cleave from the 28S rRNA/R2 co-transcript by a hepatitis

Identification and Validation of Reference Genes for Expression Analysis Using RT-qPCR in Leptocybe invasa Fisher and La Salle (Hymenoptera: Eulophidae)

open access: yesInsects, 2023
Leptocybe invasa (Hymenoptera: Eulophidae) is a globally intrusive pest. Despite extensive research into the physiological responses of this pest, our understanding of the molecular mechanisms still needs to be improved. We want to accurately investigate

Location of 5.8 S rRNA contact sites in 28 S rRNA and the effect of alpha-sarcin on the association of 5.8 S rRNA with 28 S rRNA.

open access: yesJournal of Biological Chemistry, 1983
We have constructed phage M13mp7 clones each containing the coding strand from one of three restriction fragments which collectively span the mouse 28 S rRNA gene with the exception of the 3'-terminal approximately 500 base pairs. When hybridized to 28 S rRNA, only the fragment containing the 5'-terminal 1400 nucleotides of the gene inhibited the ...

Sequence and secondary structure of moose 28S rRNA 5′terminal domain. Organisation of the 5.8S-28S rRNA complex

open access: yesNucleic Acids Research, 1982
We present the sequence of the 5' terminal 585 nucleotides of mouse 28S rRNA as inferred from the DNA sequence of a cloned gene fragment. The comparison of mouse 28S rRNA sequence with its yeast homolog, the only known complete sequence of eukaryotic nucleus-encoded large rRNA (see ref. 1, 2) reveals the strong conservation of two large stretches which
