Roles of ribosomal proteins in hematologic disorders and cancers: a review

open access: yesEmergency and Critical Care Medicine, 2023
. Ribosomes are important organelles for synthesizing proteins in cells. They are composed of ribosomal RNA and more than 80 ribosomal proteins. It is well known that an essential function of ribosomal proteins is to participate in protein translation ...

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

open access: yes, 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

Systematic identification of gene families for use as markers for phylogenetic and phylogeny- driven ecological studies of bacteria and archaea and their major subgroups [PDF]

open access: yes, 2013
With the astonishing rate that the genomic and metagenomic sequence data sets are accumulating, there are many reasons to constrain the data analyses.

Ribosomal DNA magnification in Saccharomyces cerevisiae [PDF]

open access: yesJournal of Bacteriology, 1978
Strains monosomic for chromosome I of Saccharomyces cerevisiae contain 25 to 35% fewer rRNA genes than do normal diploid strains. When these strains are repeatedly subcultured, colonies are isolated that have magnified their number of rRNA genes to the diploid amount while remaining monosomic for chromosome I.

Copy Number of Human Ribosomal Genes With Aging: Unchanged Mean, but Narrowed Range and Decreased Variance in Elderly Group

open access: yesFrontiers in Genetics, 2018
Introduction: The multi-copied genes coding for the human 18, 5.8, and 28S ribosomal RNA (rRNA) are located in five pairs of acrocentric chromosomes forming so-called rDNA.

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

open access: yesBMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Mild cognitive impairment is associated with low copy number of ribosomal genes in the genomes of elderly people

open access: yesFrontiers in Genetics, 2022
Introduction: Mild cognitive impairments (MCI) accompanying aging are associated with oxidative stress. The ability of cells to respond to stress is determined by the protein synthesis level, which depends on the ribosomes number.

Idiosyncratic evolution of conserved eukaryote proteins that are similar in sequence to archaeal or bacterial proteins [PDF]

open access: yes, 2008
Sequence comparisons have been made between the proteins of 571 prokaryote species including 46 archaea and 525 bacteria and the set of human proteins.

Genomic function during the lampbrush chromosome stage of amphibian oogenesis [PDF]

open access: yes, 1966
Throughout its lengthy developmental history the disposition of the genetic material in the amphibian oocyte nucleus differs from that in other cell types.

Phylogenetic analysis of Polystigma and its relationship to Phyllachorales

open access: yesPhytopathologia Mediterranea, 2015
Polystigma amygdalinum, which causes red leaf blotch of almond, is one of the few fungal plant pathogens to remain a taxonomic enigma, primarily because it has resisted cultivation and causes almond leaf blotch only in restricted regions of the world. To
