RNase H enables efficient repair of R-loop induced DNA damage. [PDF]
R-loops, three-stranded structures that form when transcripts hybridize to chromosomal DNA, are potent agents of genome instability. This instability has been explained by the ability of R-loops to induce DNA damage. Here, we show that persistent R-loops

Drug hypersensitivity caused by alteration of the MHC-presented self-peptide repertoire [PDF]
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 magnification in Saccharomyces cerevisiae [PDF]
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.

Idiosyncratic evolution of conserved eukaryote proteins that are similar in sequence to archaeal or bacterial proteins [PDF]
Sequence comparisons have been made between the proteins of 571 prokaryote species including 46 archaea and 525 bacteria and the set of human proteins.

Treacle controls the nucleolar response to rDNA breaks via TOPBP1 recruitment and ATR activation
DNA double-strand breaks in ribosomal DNA repeats is associated with repression of ribosomal RNA synthesis. Here the authors reveal a cooperation between TOPBP1 and Treacle in the signaling cascade that triggers transcriptional inhibition and nucleolar ...

PCR amplification of a long rDNA segment with one primer pair in agriculturally important nematodes
Ribosomal DNA has been a reliable source of taxonomic and phylogenetic markers due to its high copy number in the genome and stable variation with few polymorphisms due to the homogenizing effect of concerted evolution.

Utilization of Pyrosequencing to Monitor the Microbiome Dynamics of Probiotic Treated Poultry (Gallus gallus domesticus) during Downstream Poultry Processing [PDF]
Antibiotic growth promoters that have been historically employed to control pathogens and increase the rate of animal development for human consumption are currently banned in many countries.

A ribosome association factor (AF) was isolated from the yeast Sacchharomyces cerevisiae. Partial amino acid sequence of AF was determined from its fragment of 25 kDa isolated by treating AF with 2-(2-nitrophenylsulfenyl)-3-methyl-3'-Bromoindolenine ...

The replicative lifespan-extending deletion of SGF73 results in altered ribosomal gene expression in yeast. [PDF]
Sgf73, a core component of SAGA, is the yeast orthologue of ataxin-7, which undergoes CAG-polyglutamine repeat expansion leading to the human neurodegenerative disease spinocerebellar ataxia type 7 (SCA7).
