Regulatory Mechanisms of Exoribonuclease PNPase and Regulatory Small RNA on T3SS of Dickeya dadantii

open access: yesMolecular Plant-Microbe Interactions, 2010
The type III secretion system (T3SS) is an essential virulence factor for many bacterial pathogens. Polynucleotide phosphorylase (PNPase) is one of the major exoribonucleases in bacteria and plays important roles in mRNA degradation, tRNA processing, and

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

The Ubiquitin Ligase Zinc Finger SWIM Domain‐Containing Protein 8 Regulates Oligodendrocyte Development Through the Argonaute2/MicroRNA‐7 Axis

open access: yesGlia, Volume 74, Issue 5, May 2026.
ZSWIM8, an E3 ubiquitin ligase that broadly targets IDR‐rich proteins, drives MiR‐7‐dependent AGO2 degradation and the turnover of many RBPs. Loss of ZSWIM8 leads to MiR‐7 accumulation in oligodendrocyte progenitor cells and myelination defects in the developing brain. ABSTRACT Proteostasis of proteins with intrinsically disordered regions (IDRs) is of

Extending the Targets for Coronavirus Antivirals Beyond That of Approved Drugs: Insights From Preclinical Research

open access: yesMicrobial Biotechnology, Volume 19, Issue 5, May 2026.
Chemical structure of RIBOTAC inhibitor with metabolic handle binding as nucleotide analogue to SARS‐CoV‐2 RNA dependent RNA polymerase, its linker and the RNase L recruiter which binds RNase L monomers and mediates their dimerization that actives nuclease activity degrading the viral RNA.

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1460-1467, May 2026.
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

Proteomic Profiling of Human Extracellular Vesicles Reveals Diagnostic Biomarkers for Colon Adenocarcinoma

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
Proteomic profiling of tissue explant‐ and plasma‐derived extracellular vesicles identified colon adenocarcinoma‐associated and healthy‐associated EV proteins. A 10‐protein EV panel enabled highly sensitive blood‐based detection of colon adenocarcinoma, showed marked postoperative changes, and retained performance in an independent validation cohort ...

Antivirals Targeting Coronavirus RNA‐Dependent RNA Polymerase and Main Protease: From Mechanisms of Action to Outcomes in COVID‐19 Clinical Trials

open access: yesMicrobial Biotechnology, Volume 19, Issue 4, April 2026.
The target sites of COVID‐19 antivirals discussed in the present opinion paper, namely the RNA dependent RNA polymerase Nsp12 and of the main viral protease Nsp5, are indicated by a red star in the overview of the replication cycle of coronavirus SARS‐CoV‐2.

Elevated Wall Tension Leads to Reduced miR‐133a in the Thoracic Aorta by Exosome Release

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Reduced miR‐133a was previously found to be associated with thoracic aortic (TA) dilation, as seen in aneurysm disease. Because wall tension increases with vessel diameter (Law of Laplace), this study tested the hypothesis that elevated ...

RNA Sequencing Identifies New RNase III Cleavage Sites in Escherichia coli and Reveals Increased Regulation of mRNA

open access: yesmBio, 2017
Ribonucleases facilitate rapid turnover of RNA, providing cells with another mechanism to adjust transcript and protein levels in response to environmental conditions. While many examples have been documented, a comprehensive list of RNase targets is not
