Ribosomal protein S3: A multifunctional target of attaching/effacing bacterial pathogens

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
The extraribosomal functions of ribosomal proteins have drawn significant recent attention. Ribosomal Protein S3 (RPS3), a component of the eukaryotic 40S ribosomal subunit, is a multifunctional protein that regulates DNA repair, apoptosis, and the ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]

open access: yes, 2009
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...

The Mitochondrial Myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like Episode Syndrome-associated Human Mitochondrial tRNALeu(UUR) Mutation Causes Aminoacylation Deficiency and Concomitant Reduced Association of mRNA with Ribosomes [PDF]

open access: yes, 2000
The pathogenetic mechanism of the mitochondrial tRNALeu(UUR) A3243G transition associated with the mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome has been investigated in transmitochondrial cell lines ...

Neurodegeneration-associated instability of ribosomal DNA

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2014
Homologous recombination (HR)-mediated instability of the repetitively organized ribosomal DNA (rDNA) has been proposed as a mediator of cell senescence in yeast triggering the DNA damage response. High individual variability in the content of human rDNA suggests that this genomic region remained relatively unstable throughout evolution.

Following basal stem rot in young oil palm plantings [PDF]

open access: yes, 2005
The PCR primer GanET has previously been shown to be suitable for the specific amplification of DNA from Ganoderma boninense. A DNA extraction and PCR method has been developed that allows for the amplification of the G.

Characterization of ribosomal DNA (rDNA) in Drosophila arizonae

open access: yesGenetics and Molecular Biology, 2000
Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between ...

Increased sampling reveals novel lineages of Entamoeba: consequences of genetic diversity and host specificity for taxonomy and molecular detection. [PDF]

open access: yes, 2011
To expand the representation for phylogenetic analysis, ten additional complete Entamoeba small-subunit rRNA gene sequences were obtained from humans, non-human primates, cattle and a tortoise. For some novel sequences no corresponding morphological data

Molecular Evidence of Trichobilharzia Species (Digenea: Schistosomatidae) in the Snails of Lymnaea auricularia from Urmia Suburb, North West Iran

open access: yesIranian Journal of Parasitology, 2016
Background: The present study was carried out to detect the infection of larval stages of Trichobilharzia species in the snail Lymnaea auricularia in northwestern Iran based on DNA analysis. Methods: A total number of 320 snails of L.
