Distinct RNA profiles in subpopulations of extracellular vesicles: apoptotic bodies, microvesicles and exosomes [PDF]

, 2013
Introduction: In recent years, there has been an exponential increase in the number of studies aiming to understand the biology of exosomes, as well as other extracellular vesicles.

Molecular characterization of Sarcocystis species isolated from Chinese buffaloes in Guizhou province based on 18S rRNA and cox1 sequences

Mitochondrial DNA. Part B. Resources, 2019
The parasites from buffaloes in Guizhou province, southwest China, were suspected to be sarcocysts through morphologic observation. 18S rRNA and the subunit I of cytochrome oxidase (cox1) sequences were amplified, then implemented by phylogenetic ...

Nop9 binds the central pseudoknot region of 18S rRNA

Nucleic Acids Research, 2017
The assembly of eukaryotic ribosomes requires numerous factors that transiently associate with evolving pre-ribosomal particles. The Pumilio repeat-containing protein Nop9 briefly associates with the 90S pre-ribosome during its co-transcriptional assembly. Here, we show that Nop9 specifically binds an 11-nucleotide sequence of 18S rRNA that forms the 3΄

Application of dried blood spot sample pooling strategies for Plasmodium 18S rRNA biomarker testing to facilitate identification of infected persons in large-scale epidemiological studies

Malaria Journal, 2021
Background Plasmodium 18S rRNA is a sensitive biomarker for detecting Plasmodium infection in human blood. Dried blood spots (DBS) are a practical sample type for malaria field studies to collect, store, and transport large quantities of blood samples ...

Characterization of the TMV encapsidatlon initiation site on 18S rRNA [PDF]

Nucleic Acids Research, 1988
Tobacco Mosaic Virus capsid protein oligomers react with and encapsidate 18S rRNA from both plant and mammalian sources in vitro. The site (ei) in 18S rRNA which reacts with capsid protein to initiate the packaging reaction has been localized and partially characterized by testing the ability of transcripts from different regions of a cloned Cucurbita ...

Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

Molecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Restriction enzyme digestion of host DNA enhances universal detection of parasitic pathogens in blood via targeted amplicon deep sequencing

Microbiome, 2018
Background Targeted amplicon deep sequencing (TADS) of the 16S rRNA gene is commonly used to explore and characterize bacterial microbiomes. Meanwhile, attempts to apply TADS to the detection and characterization of entire parasitic communities have been

Characterization of the two intra-individual sequence variants in the 18S rRNA gene in the plant parasitic nematode, Rotylenchulus reniformis. [PDF]

PLoS ONE, 2013
The 18S rRNA gene is fundamental to cellular and organismal protein synthesis and because of its stable persistence through generations it is also used in phylogenetic analysis among taxa.

The Parasite that Causes Whirling Disease, \u3cem\u3eMyxobolus cerebralis\u3c/em\u3e, is Genetically Variable Within and Across Spatial Scales [PDF]

, 2012
Understanding the genetic structure of parasite populations on the natural landscape can reveal important aspects of disease ecology and epidemiology and can indicate parasite dispersal across the landscape.

Genetic Diversity and Potential Function of Microbial Symbionts Associated with Newly Discovered Species of Osedax Polychaete Worms [PDF]

, 2007
We investigated the genetic diversity of symbiotic bacteria associated with two newly discovered species of Osedax from Monterey Canyon, CA, at 1,017-m (Osedax Monterey Bay sp. 3 "rosy" [Osedax sp. MB3]) and 381-m (Osedax Monterey Bay sp.
