[Current advances in the analysis of free RNA modified nucleosides by high performance liquid chromatography-tandem mass spectrometry].

Post-transcriptional ribonucleic acid (RNA) modifications play crucial roles in regulating gene expression, with both eukaryotic and prokaryotic RNA exhibiting more than 170 distinct and ubiquitous modifications. RNA turnover generates numerous free nucleosides, including unmodified nucleosides and a variety of modified ones. Unlike unmodified nucleosides, modified nucleosides are not further degraded or used in the salvage-synthesis pathway owing to a lack of specific enzymes, which leads to the cytosolic accumulation or cellular efflux of modified nucleosides.

Why is pollen in Camellia oleifera inedible to honeybees?

This Commentary examines a recent study that addressed a long-standing controversy: Is the lethal effect of Tea-oil Camellia on honeybee larvae due to nectar or pollen toxicity? Flowers of Camellia oleifera are adapting to bird pollination, evolving 'anti-bee' traits such as theasaponin-containing pollen, which is toxic to bee larvae.

Developing an enhanced chimeric permuted intron-exon system for circular RNA therapeutics.

: Circular RNA (circRNA) therapeutics hold great promise as an iteration strategy in messenger RNA (mRNA) therapeutics due to their inherent stability and durable protein translation capability. Nevertheless, the efficiency of RNA circularization remains a significant constraint, particularly in establishing large-scale manufacturing processes for producing highly purified circRNAs. Hence, it is imperative to develop a universal and more efficient RNA circularization system when considering synthetic circRNAs as therapeutic agents with prospective clinical applications.
