Nat Plants. 2015 Jan 08;1:14005. doi: 10.1038/nplants.2014.5.

Self-incompatibility (SI) systems in flowering plants distinguish self- and non-self pollen to prevent inbreeding. While other SI systems rely on the self-recognition between specific male- and female-determinants, the Solanaceae family has a non-self recognition system resulting in the detoxification...

Particle-mediated Intravenous Delivery of Antigen mRNA Results in Strong Antigen-specific T-cell Responses Despite the Induction of Type I Interferon.

Molecular therapy. Nucleic acids

Broos K, Van der Jeught K, Puttemans J, Goyvaerts C, Heirman C, Dewitte H, Verbeke R, Lentacker I, Thielemans K, Breckpot K.

Mol Ther Nucleic Acids. 2016 Jun 21;5(6):e326. doi: 10.1038/mtna.2016.38.

Cancer vaccines based on mRNA are extensively studied. The fragile nature of mRNA has instigated research into carriers that can protect it from ribonucleases and as such enable its systemic use. However, carrier-mediated delivery of mRNA has been linked...

XRN1: A Major 5' to 3' Exoribonuclease in Eukaryotic Cells.

The Enzymes

Geisler S, Coller J.
PMID: 27166442
Enzymes. 2012;31:97-114. doi: 10.1016/B978-0-12-404740-2.00005-7. Epub 2012 Sep 29.

The degradation of RNA is a critical aspect of gene regulation. Correspondingly, ribonucleases exist within the cell to degrade RNA in specific cellular contexts. An important and conserved ribonuclease is called XRN1. This enzyme, an exoribonuclease, degrades RNA in...

mRNA degradation and maturation in prokaryotes: the global players.

Biomolecular concepts

Laalami S, Putzer H.
PMID: 25962050
Biomol Concepts. 2011 Dec 01;2(6):491-506. doi: 10.1515/BMC.2011.042.

The degradation of messenger RNA is of universal importance for controlling gene expression. It directly affects protein synthesis by modulating the amount of mRNA available for translation. Regulation of mRNA decay provides an efficient means to produce just the...

Action of the Style Product of the Self-Incompatibility Gene of Nicotiana alata (S-RNase) on in Vitro-Grown Pollen Tubes.

The Plant cell

Gray JE, McClure BA, Bonig I, Anderson MA, Clarke AE.
PMID: 12324597
Plant Cell. 1991 Mar;3(3):271-283. doi: 10.1105/tpc.3.3.271.

The products of the S-locus expressed in female tissues of Nicotiana alata are ribonucleases (S-RNases). The arrest of growth of incompatible pollen tubes in styles may result from entry of the S-RNase into the pollen tube and degradation of...

MicroRNAs in gene regulation: when the smallest governs it all.

Journal of biomedicine & biotechnology

Ouellet DL, Perron MP, Gobeil LA, Plante P, Provost P.
PMID: 17057368
J Biomed Biotechnol. 2006;2006(4):69616. doi: 10.1155/JBB/2006/69616.

Encoded by the genome of most eukaryotes examined so far, microRNAs (miRNAs) are small approximately 21-nucleotide (nt) noncoding RNAs (ncRNAs) derived from a biosynthetic cascade involving sequential processing steps executed by the ribonucleases (RNases) III Drosha and Dicer. Following...

Messenger RNA Turnover Processes in Escherichia coli, Bacillus subtilis, and Emerging Studies in Staphylococcus aureus.

International journal of microbiology

Int J Microbiol. 2009;2009:525491. doi: 10.1155/2009/525491. Epub 2009 Mar 05.

The regulation of mRNA turnover is a recently appreciated phenomenon by which bacteria modulate gene expression. This review outlines the mechanisms by which three major classes of bacterial trans-acting factors, ribonucleases (RNases), RNA binding proteins, and small noncoding RNAs...

Multicomponent synthesis of artificial nucleases and their RNase and DNase activity.

Beilstein journal of organic chemistry

Beilstein J Org Chem. 2011;7:1135-40. doi: 10.3762/bjoc.7.131. Epub 2011 Aug 19.

The synthesis of new, artificial ribonucleases containing two amino acid residues connected by an aliphatic linker has been developed. Target molecules were synthesized via a catalytic three-component Ugi reaction from aliphatic diisocyanides. Preliminary investigations proved unspecific nuclease activity of...
