Regulation of virulence in Francisella tularensis by small non-coding RNAs [PDF]

, 2011
Using a cDNA cloning and sequencing approach we have shown that Francisella tularensis expresses homologues of several small RNAs (sRNAs) that are well-conserved among diverse bacteria.

5S Ribosomal RNA genes of the newt Notophthalmus viridescens [PDF]

Nucleic Acids Research, 1981
The genes which code for the 5S ribosomal RNA in the newt, Notophthalmus viridescens have been cloned and analyzed. Two types of repeating unit were detected: a major type consisting of a 120 bp coding region with a 111 bp spacer, and a minor type composed of a coding region, a pseudogene, and a 113 bp spacer.

Enterobius vermicularis: ancient DNA from north and south American human coprolites

Memorias do Instituto Oswaldo Cruz, 2003
A molecular paleoparasitological diagnostic approach was developed for Enterobius vermicularis. Ancient DNA was extracted from 27 coprolites from archaeological sites in Chile and USA.

The emerging roles of ribosome biogenesis in craniofacial development. [PDF]

, 2014
Neural crest cells (NCCs) are a transient, migratory cell population, which originates during neurulation at the neural folds and contributes to the majority of tissues, including the mesenchymal structures of the craniofacial skeleton.

Targeting the CMKLR1‐Mediated Signaling Rebalances Immunometabolism State in Middle‐Age Testicular Macrophages

Advanced Science, EarlyView.
In middle age, testicular CMKLR1⁺ macrophages exhibited a pro‐inflammatory immunometabolic profile, mediated by adipose signals associated with high BMI. However, inhibition of CMKLR1 signaling, either through Cmklr1 genetic ablation or treatment with a CMKLR1 antagonist peptide, can reverse this phenotype.

DNA-methylation dependent regulation of embryo-specific 5S ribosomal DNA cluster transcription in adult tissues of sea urchin Paracentrotus lividus [PDF]

, 2013
We have previously reported a molecular and cytogenetic characterization of three different 5S rDNA clusters in the sea urchin Paracentrotus lividus and recently, demonstrated the presence of high heterogeneity in functional 5S rRNA.
