Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.

Endoplasmic reticulum stress and the unfolded protein response in lung diseases: molecular pathways and therapeutic interventions

open access: yesThe Journal of Pathology, Volume 269, Issue 3, Page 268-283, July 2026.
Abstract Endoplasmic reticulum stress (ERS) occurs when the protein‐folding capacity of the endoplasmic reticulum (ER) is overwhelmed, triggering the unfolded protein response (UPR) to restore homeostasis. However, severe or persistent ERS can shift the UPR toward pro‐inflammatory, apoptotic, and fibrotic signaling, thereby exacerbating tissue injury ...

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

Molecular Signatures of Peripheral and Central Dental Pulp Subpopulations in Response to Streptococcus mutans: A Bulk RNA‐Seq Analysis

open access: yesInternational Endodontic Journal, Volume 59, Issue 7, Page 1402-1415, July 2026.
ABSTRACT Aim The dental pulp is an immunologically active tissue that responds dynamically to cariogenic challenge. Peripheral pulp cells adjacent to dentine encounter bacterial stimuli earlier than cells located in the central pulp. To investigate signalling and immune interactions, this study profiled the transcriptomes of dentine‐adherent cells ...

A Novel Endoribonuclease, RNase LS, in Escherichia coli [PDF]

open access: yesGenetics, 2005
Abstract The dmd gene of bacteriophage T4 is required for the stability of late-gene mRNAs. When this gene is mutated, late genes are globally silenced because of rapid degradation of their mRNAs. Our previous work suggested that a novel Escherichia coli endonuclease, RNase LS, is responsible for the rapid degradation of mRNAs.

Interferon induced circRNAs escape herpesvirus host shutoff and suppress lytic infection

open access: yesEMBO Reports
To globally profile circRNAs, we employ RNA-Sequencing paired with chimeric junction analysis for alpha-, beta-, and gamma-herpesvirus infection. We find circRNAs are, as a population, resistant to host shutoff. We validate this observation using ectopic

The cooperative regulation of miR‐221 by APE1 and AUF1 impacts p27Kip1 defining a miR signature relevant for cervical cancer

open access: yesFEBS Open Bio, Volume 16, Issue 6, Page 1222-1236, June 2026.
A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Low‐Dose H2O2 Priming Improves Performance Under Simulated Marine Heatwave Conditions in a Coastal Bivalve

open access: yesGlobal Challenges, Volume 10, Issue 6, June 2026.
Low‐dose hydrogen peroxide priming shapes Manila clam responses to simulated marine heatwaves, which showed faster burrowing behavior, limited transcriptional disruption, and reduced opportunistic microbiota. A long‐term field trial confirms no detectable adverse effects, supporting redox‐based chemical priming as a feasible resilience strategy in ...

Pyrimidine-specific cleavage by an endoribonuclease of Saccharomyces cerevisiae [PDF]

open access: yesJournal of Bacteriology, 1985
An endoribonuclease with pyrimidine cleavage site specificity was isolated from Saccharomyces cerevisiae. The enzyme had a pH optimum of 6 to 7 and did not require a divalent cation. It was inhibited by 5 X 10(-5) M ethidium bromide, although it appeared to be single strand specific.

Vacuolization as a Novel Approach to Cancer Therapy

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
This review discusses the novel strategy of inducing vacuole formation in cancer cells using small molecules, that induce nonapoptotic cell death mechanisms, such as paraptosis, oncosis, autophagy, and methuosis, and its potential in overcoming resistance to apoptosis‐based cancer therapies.
