Ribosomal Dysfunction Is a Common Pathomechanism in Different Forms of Trichothiodystrophy

open access: yesCells, 2023
Mutations in a broad variety of genes can provoke the severe childhood disorder trichothiodystrophy (TTD) that is classified as a DNA repair disease or a transcription syndrome of RNA polymerase II.

Karyotype description and comparative chromosomal mapping of rDNA and U2 snDNA sequences in Eigenmannia limbata and E. microstoma (Teleostei, Gymnotiformes, Sternopygidae) [PDF]

open access: yesComparative Cytogenetics, 2022
The genus Eigenmannia Jordan et Evermann,1896 includes electric fishes endemic to the Neotropical region with extensive karyotype variability and occurrence of different sex chromosome systems, however, cytogenetic studies within this group are ...

Evaluating RNA status for RT-PCR in extracts of postmortem human brain tissue

open access: yesBioTechniques, 2004
Total RNA was extracted from 105 individual postmortem human brain samples representing a range of postmortem conditions. To improve upon parameters currently used to screen for RNA quality, electropherogram patterns generated by the Agilent Bioanalyzer ...

Nucleotide sequence of the 5′-and 3′-domains for rabbit 18S ribosomal RNA [PDF]

open access: yesNucleic Acids Research, 1982
By direct RNA sequence analysis we have determined the primary structures of both the 5' and 3' domains for rabbit 18S ribosomal RNA. Purified 18S rRNA was labeled in vitro at either its 5' or 3' terminus with 32P, base-specifically fragmented enzymatically and chemically, and the resulting fragments electrophoretically fractionated by size in adjacent

An RNA-binding complex involved in ribosome biogenesis contains a protein with homology to tRNA CCA-adding enzyme. [PDF]

open access: yesPLoS Biology, 2013
A multitude of proteins and small nucleolar RNAs transiently associate with eukaryotic ribosomal RNAs to direct their modification and processing and the assembly of ribosomal proteins. Utp22 and Rrp7, two interacting proteins with no recognizable domain,

Selection of Reference Genes for RT-qPCR Analysis Under Intrinsic Conditions in the Hawthorn Spider Mite, Amphitetranychus viennensis (Acarina: Tetranychidae)

open access: yesFrontiers in Physiology, 2019
Hawthorn spider mite, Amphitetranychus viennensis Zacher, is one of the most devastating pests of deciduous fruit trees. The overall goal of this research is to develop a standardized protocol for real-time quantitative reverse transcription PCR (RT-qPCR)

Exploring valid reference genes for quantitative real-time PCR analysis in Sesamia inferens (Lepidoptera: Noctuidae). [PDF]

open access: yesPLoS ONE, 2015
The pink stem borer, Sesamia inferens, which is endemic in China and other parts of Asia, is a major pest of rice and causes significant yield loss in this host plant. Very few studies have addressed gene expression in S. inferens. Quantitative real-time

Genome-wide CRISPR screens identify noncanonical translation factor eIF2A as an enhancer of SARS-CoV-2 programmed −1 ribosomal frameshifting

open access: yesCell Reports, 2023
Summary: Many positive-strand RNA viruses, including all known coronaviruses, employ programmed −1 ribosomal frameshifting (−1 PRF) to regulate the translation of polycistronic viral RNAs.

Nucleotide sequence and evolution of the 18S ribosomal RNA gene in maize mitochondria [PDF]

open access: yesNucleic Acids Research, 1984
The nucleotide sequence of the gene coding for the 18S ribosomal RNA of maize mitochondria has been determined and a model for the secondary structure is proposed. Dot matrix analysis has been used to compare the extent and distribution of sequence similarities of the entire maize mitochondrial 18S rRNA sequence with that of 15 other small subunit rRNA

Evaluation of three molecular markers for identification of European primary parasitoids of cereal aphids and their hyperparasitoids. [PDF]

open access: yesPLoS ONE, 2017
Aphids are major pests of cereal crops and a suite of hymenopteran primary parasitoids play an important role in regulating their populations. However, hyperparasitoids may disrupt the biocontrol services provided by primary parasitoids.
