Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

open access: yes, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

A parsimonay analysis of eukaryotic small subunit ribosomal RNA (″18 S″) sequences [PDF]

open access: yesArchives Internationales de Physiologie, de Biochimie et de Biophysique, 1993
Using the principles of Felsenstein's DNA parsimony analysis program (package PHYLIP 3.2), a program with the capacity to handle data sets of the magnitude of ss rRNA has been developed. With this program we applied an heuristic approach to 83 s rRNA sequences from the Antwerp data bank, compared along 4230 positions of their alignment.

Certain Adenylated Non-Coding RNAs, Including 5′ Leader Sequences of Primary MicroRNA Transcripts, Accumulate in Mouse Cells following Depletion of the RNA Helicase MTR4 [PDF]

open access: yes, 2014
RNA surveillance plays an important role in posttranscriptional regulation. Seminal work in this field has largely focused on yeast as a model system, whereas exploration of RNA surveillance in mammals is only recently begun.

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 ...

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.

Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity [PDF]

open access: yes, 2010
Molecular taxonomy is one of the most promising yet challenging fields of biology. Molecular markers such as nuclear and mitochondrial genes are being used in a variety of studies surveying marine nematode taxa.

Monophyly of brachiopods and phoronids: reconciliation of molecular evidence with Linnaean classification (the subphylum Phoroniformea nov.) [PDF]

open access: yes, 2000
Molecular phylogenetic analyses of aligned 18S rDNA gene sequences from articulate and inarticulate brachiopods representing all major extant lineages, an enhanced set of phoronids and several unrelated protostome taxa, confirm previous indications that ...

18S ribosomal RNA gene phylogeny for some Rhabditidae related to Caenorhabditis.

open access: yesMolecular biology and evolution, 1995
We have investigated the molecular evolution of the nucleotide sequences of 18S ribosomal RNA genes (18S rDNA) from a set of nematodes in the family Rhabditidae (Nematoda: Secernentea).

Regulated Inositol‐Requiring Protein 1‐Dependent Decay as a Mechanism of Corin RNA and Protein Deficiency in Advanced Human Systolic Heart Failure [PDF]

open access: yes, 2014
BACKGROUND: The compensatory actions of the endogenous natriuretic peptide system require adequate processing of natriuretic peptide pro‐hormones into biologically active, carboxyl‐terminal fragments.
