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.

Mosaic Arrangement of the 5S rDNA in the Aquatic Plant Landoltia punctata (Lemnaceae)

Frontiers in Plant Science, 2021
Duckweeds are a group of monocotyledonous aquatic plants in the Araceae superfamily, represented by 37 species divided into five genera. Duckweeds are the fastest growing flowering plants and are distributed around the globe; moreover, these plants have ...

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.

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.

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.

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.

Overexpression of a Brix Domain-Containing Ribosome Biogenesis Factor ARPF2 and its Interactor ARRS1 Causes Morphological Changes and Lifespan Extension in Arabidopsis thaliana

Frontiers in Plant Science, 2018
The Brix domain is a conserved domain in several proteins involved in ribosome biogenesis in yeast and animals. In the Arabidopsis genome, six Brix domain-containing proteins are encoded; however, their molecular functions have not been fully ...

5S ribosomal RNA database

, 2016
Ribosomal 5S RNA (5S rRNA) is a conserved component of the large subunit of all cytoplasmic and the majority of organellar ribosomes in all organisms.  5SRNAdb is the first database that provides a high quality reference set of ribosomal 5S RNAs across three domains of life.
