The 5′ Cap Epitranscriptome and Beyond: Natural and Engineered 5′ Cap Modifications for Optimizing mRNA Therapeutics and Functional Studies

open access: yesChemMedChem, Volume 21, Issue 2, January 2026.
5′ Cap modifications can be introduced via enzymes or chemical synthesis. Natural and non‐natural 5′ cap structures affect mRNA properties, including translation (T), stability (S), and/or immunogenicity (I). Eukaryotic mRNAs made by in vitro transcription have emerged as medical modalities for vaccination and protein replacement therapy. The 5′ cap is

Structure Modeling Protocols for Protein Multimer and RNA in CASP16 With Enhanced MSAs, Model Ranking, and Deep Learning

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 167-182, January 2026.
ABSTRACT We present the methods and results of our protein complex and RNA structure predictions at CASP16. Our approach integrated multiple state‐of‐the‐art deep learning models with a consensus‐based scoring method. To enhance the depth of multiple sequence alignments (MSAs), we employed a large metagenomic sequence database.

Structural and functional studies of the decapping exoribonucleases [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Recent studies showed that two homologous yeast proteins, Rai1 and Dxo1, function in a quality control mechanism to clear cells of incompletely 5' end-capped messenger RNAs (mRNAs). Rai1 possesses a novel decapping activity that can remove the entire cap structure dinucleotide from an mRNA.

The Arabidopsis deNADding Enzyme DXO1 Modulates the Plant Immunity Response

open access: yesPlant, Cell &Environment, Volume 49, Issue 1, Page 32-50, January 2026.
ABSTRACT DXO1, the only DXO homolog in Arabidopsis, due to its plant‐specific features, exhibits strong deNADding enzymatic activity but has no apparent role in 5′ QC. Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited.

Regular versus Irregular Exercise Differentially Modulates Hippocampal‐Hepatic Acetylcholine Flux to Coordinate Fear Memory Extinction and Liver Inflammation

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
Ma et al. report the hippocampal and hepatic acetylcholine (ACh) levels are differently modulated by regular versus irregular exercise, which contributes to coordinate hippocampal astrocyte activity and hepatic FBXL6high neutrophil recruitment. This ACh‐modulated brain‐liver circuit links the effects of exercise on fear memory extinction and liver ...

Five‐Year (2017–2022) Evolutionary Dynamics of Human Coronavirus OC43 in Southern France Based on Whole Genome Next‐Generation Sequencing

open access: yesJournal of Medical Virology, Volume 97, Issue 12, December 2025.
ABSTRACT HCoV‐OC43 genomes and their evolution are scarcely studied worldwide and in France, with only 361 genomes available as of October 2023. Here, an in‐house PCR amplification system was implemented to obtain retrospectively by next‐generation sequencing, then analyze HCoV‐OC43 genomes for infections diagnosed with this virus in southern France ...

Xrn1 Exoribonuclease—An Intrinsic Marker of Yeast Population Growth

open access: yesFrontiers in Bioscience-Elite
Background: Xrn1 exoribonuclease is the major mRNA degradation enzyme in Saccharomyces cerevisiae. In exponentially growing cells, Xrn1 is localised in the yeast cells and directs the degradation of mRNA molecules. Xrn1 is gradually deposited and presumably inactivated in the processing bodies (P-bodies) as the yeast population ages.
