RNA folding landscapes from explicit solvent all-atom simulations [PDF]

open access: yesarXiv, 2022
Atomically detailed simulations of RNA folding have proven very challenging in view of the difficulties of developing realistic force fields and the intrinsic computational complexity of sampling rare conformational transitions. To tackle both these issues, we extend to RNA an enhanced path sampling method previously successfully applied to proteins ...

Recognition of Cognate Transfer RNA by the 30S Ribosomal Subunit

open access: yesScience, 2001
Crystal structures of the 30S ribosomal subunit in complex with messenger RNA and cognate transfer RNA in the A site, both in the presence and absence of the antibiotic paromomycin, have been solved at between 3.1 and 3.3 angstroms resolution.

Using Guided Transfer Learning to Predispose AI Agent to Learn Efficiently from Small RNA-sequencing Datasets [PDF]

open access: yesarXiv, 2023
Given the increasing availability of RNA-seq data and its complex and heterogeneous nature, there has been growing interest in applying AI/machine learning methodologies to work with such data modalities. However, because omics data is characterized by high dimensionality and low sample size (HDLSS), current attempts at integrating AI in this domain ...

Combining simulations and solution experiments as a paradigm for RNA force field refinement [PDF]

open access: yesJ. Chem. Theory Comput., 2016, 12 (12), pp 6192-6200, 2016
Recent computational efforts have shown that the current potential energy models used in molecular dynamics are not accurate enough to describe the conformational ensemble of RNA oligomers and suggest that molecular dynamics should be complemented with experimental data.

Small RNAs and extracellular vesicles in filarial nematodes: from nematode development to diagnostics [PDF]

open access: yes, 2016
Parasitic nematodes have evolved sophisticated mechanisms to communicate with their hosts in order to survive and successfully establish an infection. The transfer of RNA within extracellular vesicles (EVs) has recently been described as a mechanism that

7-Methylguanosine Modifications in Transfer RNA (tRNA)

open access: yesInternational Journal of Molecular Sciences, 2018
More than 90 different modified nucleosides have been identified in tRNA. Among the tRNA modifications, the 7-methylguanosine (m7G) modification is found widely in eubacteria, eukaryotes, and a few archaea.

Machine learning a model for RNA structure prediction [PDF]

open access: yesNAR Genom. Bioinform. 2, lqaa090 (2020), 2020
RNA function crucially depends on its structure. Thermodynamic models currently used for secondary structure prediction rely on computing the partition function of folding ensembles, and can thus estimate minimum free-energy structures and ensemble populations.

Directly visualized glioblastoma-derived extracellular vesicles transfer RNA to microglia/macrophages in the brain.

open access: yesNeuro-Oncology, 2016
BACKGROUND To understand the ability of gliomas to manipulate their microenvironment, we visualized the transfer of vesicles and the effects of tumor-released extracellular RNA on the phenotype of microglia in culture and in vivo. METHODS Extracellular

Platelets and tumor-associated RNA transfer.

open access: yesBlood, 2021
Until recently the nucleic acid content of platelets was considered to be fully determined by their progenitor megakaryocyte. However, it is now well understood that additional mediators (e.g.

PtRFdb: a database for plant transfer RNA-derived fragments

open access: yesDatabase J. Biol. Databases Curation, 2018
Transfer RNA-derived fragments (tRFs) represent a novel class of small RNAs (sRNAs) generated through endonucleolytic cleavage of both mature and precursor transfer RNAs (tRNAs).
