Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]

open access: yes, 2004
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...

Determination of ribonuclease sequence-specificity using Pentaprobes and mass spectrometry [PDF]

open access: yes, 2012
The VapBC toxin-antitoxin (TA) family is the largest of nine identified TA families. The toxin, VapC, is a metal-dependent ribonuclease that is inhibited by its cognate antitoxin, VapB. Although the VapBCs are the largest TA family, little is known about

RNA-Catalyzed RNA Ligation on an External RNA Template [PDF]

open access: yesChemistry & Biology, 2002
Variants of the hc ligase ribozyme, which catalyzes ligation of the 3' end of an RNA substrate to the 5' end of the ribozyme, were utilized to evolve a ribozyme that catalyzes ligation reactions on an external RNA template. The evolved ribozyme catalyzes the joining of an oligonucleotide 3'-hydroxyl to the 5'-triphosphate of an RNA hairpin molecule ...

RNA Chemistry for RNA Biology

open access: yesCHIMIA, 2019
Advances in the chemical synthesis of RNA have opened new possibilities to address current questions in RNA biology. Access to site-specifically modified oligoribonucleotides is often a pre-requisite for RNA chemical-biology projects. Driven by the enormous research efforts for development of oligonucleotide therapeutics, a wide range of ...

Cooperativity and Interdependency between RNA Structure and RNA–RNA Interactions [PDF]

open access: yesNon-Coding RNA, 2021
Complex RNA–RNA interactions are increasingly known to play key roles in numerous biological processes from gene expression control to ribonucleoprotein granule formation. By contrast, the nature of these interactions and characteristics of their interfaces, especially those that involve partially or wholly structured RNAs, remain elusive.

RT-PCR detection of SARS-CoV-2 in nasopharyngeal and salivary specimens: contribution of alternative collection systems and extraction processes to cope with mass screening. Interpretation of low viral loads

open access: yesJournal of Laboratory Medicine, 2022
Due to massive screening of the persistent coronavirus SARS-CoV-2, supply difficulties emerged for swabs and extraction reagents leading to test alternative choices.

Fast prediction of RNA-RNA interaction [PDF]

open access: yesAlgorithms for Molecular Biology, 2009
Abstract Background Regulatory antisense RNAs are a class of ncRNAs that regulate gene expression by prohibiting the translation of an mRNA by establishing stable interactions with a target sequence. There is great demand for efficient computational methods to predict the specific interaction between an ncRNA and its ...
