Pre-symptomatic Parkinson’s disease blood test quantifying repetitive sequence motifs in transfer RNA fragments

open access: yesNature Aging
Early, efficient Parkinson’s disease (PD) tests may facilitate pre-symptomatic diagnosis and disease-modifying therapies. Here we report elevated levels of PD-specific transfer RNA fragments carrying a conserved sequence motif (RGTTCRA-tRFs) in the ...

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

open access: yesJournal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase

A novel 5’tRNA-derived fragment tRF-Tyr inhibits tumor progression by targeting hnRNPD in gastric cancer

open access: yesCell Communication and Signaling
Transfer RNA-derived small RNAs (tsRNAs), including tRNA-derived fragments (tRFs) and tRNA halves (tiRNAs), constitute a novel class of small noncoding RNAs (sncRNAs).

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Advances of transfer RNA-derived fragments in age-related diseases

open access: yesShiyong laonian yixue
Transfer RNA-derived fragments (tRFs), generated through specific nuclease cleavage of transfer RNAs (tRNAs), represent a class of non-coding RNAs characterized by high evolutionary conservation, structural stability, and functional diversity.

High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Photochemistry of CryB from Rhodobacter sphaeroides

open access: yesPhotochemistry and Photobiology, EarlyView.
Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.

Linking dynamic cerebral autoregulation and inhibitory executive function: Role of modifiable behaviours

open access: yesExperimental Physiology, EarlyView.
Abstract Dynamic cerebral autoregulation (dCA) stabilises cerebral blood flow (CBF) against rapid fluctuations in perfusion pressure and may serve as a key physiological mediator of cognitive function. Inhibitory executive function, a core domain essential for goal‐directed behaviour, is influenced by modifiable lifestyle factors such as physical ...

Blind Estimation Versus Direct Measurement of the Arterial Input Function in Dynamic Contrast‐Enhanced MRI of the Breast

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1947-1955, October 2026.
PurposeAccurate arterial input functions (AIFs) are essential for quantitative dynamic contrast‐enhanced (DCE) MRI, yet direct measurement is challenging and population‐averaged AIFs neglect patient‐specific variability. Blind deconvolution provides an alternative by estimating patient‐specific AIFs directly from tissue data, up to a scale factor. This

METTL18 is Required for Developmental, Metabolic, and Endocrine Regulation of Mammalian Growth

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
METTL18 is essential for histidine Nτ‐methylation of proteins, normal embryonic development, iron and lipid metabolism, and hormone signaling pathways that support postnatal growth in mice. The main points of this study are as follows: First, mouse METTL18 catalyzes histidine Nτ‐methylation. Next, Mettl18 KO embryos are significantly smaller than their
