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

Advanced Science, EarlyView.
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.

Sensor dimer disruption as a new mode of action to block the IRE1-mediated unfolded protein response

Computational and Structural Biotechnology Journal, 2022
The unfolded protein response (UPR) is activated to cope with an accumulation of improperly folded proteins in the Endoplasmic reticulum (ER). The Inositol requiring enzyme 1α (IRE1α) is the most evolutionary conserved transducer of the UPR.

ERAD Component MoHrd3 Facilitates Pathogenicity and Establishes a Direct Regulation on Autophagy in Magnaporthe Oryzae

Advanced Science, EarlyView.
MoHrd3 plays a crucial role in regulating the pathogenicity of Magnaporthe oryzae. As an ER‐associated degradation component, MoHrd3 involves in ER stress‐triggered autophagy. It facilitates the fusion between the autophagosome and the vacuole via enhancing the interaction between MoAtg8 and MoYpt7.

The Unraveling Truth About IRE1 and MicroRNAs in Diabetes [PDF]

Diabetes, 2016
Wound healing is a well-regulated complex process that occurs as a cellular response to injury and consists of four phases: hemostasis, inflammation, proliferation, and remodeling (1). Many factors, such as diabetes and obesity, interfere with these stages and lead to wound healing defect.

IRE1 RNase controls CD95-mediated cell death [PDF]

, 2022
Abstract Signalling by the Unfolded Protein Response (UPR) or by the Death Receptors (DR) represents cellular stress pathways frequently activated towards pro-tumoral outputs in cancer. Experimental evidence has highlighted functional links between the UPR and the DR TRAIL-R1/2.

Activation of the IRE1 RNase through remodeling of the kinase front pocket by ATP-competitive ligands

Nature Communications, 2020
The RNase activity of Inositol-Requiring Enzyme 1 (IRE1) can be allosterically regulated by ATP-competitive inhibitors of the IRE1 kinase domain. Here, the authors identify ATP-competitive IRE1 RNase activators with improved selectivity and cellular ...

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

Advanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose

Peptidomimetic‐based identification of FDA‐approved compounds inhibiting IRE1 activity [PDF]

The FEBS Journal, 2020
Inositol‐requiring enzyme 1 (IRE1) is a bifunctional serine/threonine kinase and endoribonuclease that is a major mediator of the unfolded protein response (UPR) during endoplasmic reticulum (ER) stress. Tumour cells experience ER stress due to adverse environmental cues such as hypoxia or nutrient shortage and high metabolic/protein‐folding demand. To

Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

The UPR reduces glucose metabolism via IRE1 signaling

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2017
Neurons are highly dependent on glucose. A disturbance in glucose homeostasis therefore poses a severe risk that is counteracted by activation of stress responses to limit damage and restore the energy balance. A major stress response that is activated under conditions of glucose deprivation is the unfolded protein response (UPR) that is aimed to ...
