Evolutionary trends in animal ribosomal DNA loci: introduction to a new online database

Chromosoma, 2017
Ribosomal DNA (rDNA) loci encoding 5S and 45S (18S-5.8S-28S) rRNAs are important components of eukaryotic chromosomes. Here, we set up the animal rDNA database containing cytogenetic information about these loci in 1343 animal species (264 families ...

DNA Methylation Analysis of Ribosomal DNA in Adults With Down Syndrome

Frontiers in Genetics, 2022
Control of ribosome biogenesis is a critical aspect of the regulation of cell metabolism. As ribosomal genes (rDNA) are organized in repeated clusters on chromosomes 13, 14, 15, 21, and 22, trisomy of chromosome 21 confers an excess of rDNA copies to ...

Drug hypersensitivity caused by alteration of the MHC-presented self-peptide repertoire [PDF]

, 2012
Idiosyncratic adverse drug reactions are unpredictable, dose independent and potentially life threatening; this makes them a major factor contributing to the cost and uncertainty of drug development. Clinical data suggest that many such reactions involve

Ribosomal DNA copy loss and repeat instability in ATRX-mutated cancers

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance We demonstrate that ATRX maintains ribosomal DNA (rDNA) heterochromatin formation and stability. ATRX-depleted cells suffer extensive rDNA copy loss, resulting in a reduced ribosomal RNA transcription output and an increased sensitivity to ...

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

, 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.

Comparative analyses of classical phenotypic method and ribosomal RNA gene sequencing for identification of medically relevant Candida species

Memorias do Instituto Oswaldo Cruz, 2013
As the distribution of Candida species and their susceptibility to antifungal agents have changed, a new means of accurately and rapidly identifying these species is necessary for the successful early resolution of infection and the subsequent reduction ...

Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. [PDF]

, 2018
Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined.

A binary vector for transferring genomic libraries to plants [PDF]

, 1986
The transformation of mutant plants with a complete recombinant library derived from wild-type DNA followed by assay of transformed plants for complementation of the mutant phenotype is a promising method for the isolation of plant genes.
