Zhangfei/CREB-ZF - a potential regulator of the unfolded protein response. [PDF]

PLoS ONE, 2013
Cells respond to perturbations in the microenvironment of the endoplasmic reticulum (ER), and to the overloading of its capacity to process secretory and membrane-associate proteins, by activating the Unfolded Protein Response (UPR).

The IRE1‐XBP1s Axis Drives Inflammatory Osteolysis by Regulating a 5‐HT Dependent Endogenous Anti‐Autophagy Mechanism

Advanced Science, EarlyView.
A previously unrecognized IRE1‐XBP1s‐Slc6a4 signaling axis links endoplasmic reticulum stress to serotonin metabolism, autophagy, and inflammatory osteoclastogenesis. By promoting intracellular serotonin uptake and reducing endogenous 3‐methyladenine accumulation, this pathway accelerates inflammatory bone destruction and provides a promising ...

Endoplasmic Reticulum Stress in Intestinal Epithelial Cell Function and Inflammatory Bowel Disease

Gastroenterology Research and Practice, 2015
In eukaryotic cells, perturbation of protein folding homeostasis in the endoplasmic reticulum (ER) causes accumulation of unfolded and misfolded proteins in the ER lumen, which activates intracellular signaling pathways termed the unfolded protein ...

Activation of the unfolded protein response is required for defenses against bacterial pore-forming toxin in vivo.

PLoS Pathogens, 2008
Pore-forming toxins (PFTs) constitute the single largest class of proteinaceous bacterial virulence factors and are made by many of the most important bacterial pathogens. Host responses to these toxins are complex and poorly understood. We find that the

Proteostasis in the regulation of pancreatic islet cell plasticity. [PDF]

J Diabetes Investig
Adaptive proteostasis integrates protein synthesis, folding, trafficking, and degradation through ISR, UPR, ER stress responses, autophagy, and proteasomal degradation. In pancreatic islet cells, this coordinated network preserves protein quality, secretory function, proliferation, and survival, enabling adaptation to metabolic stress and aging while ...

Aberrant GRP78 Phase Transition Sustains Endothelial IRE1α Signaling and Drives Blood–Brain Barrier Failure in Cerebral Amyloid Angiopathy

Advanced Science, EarlyView.
Vascular Aβ40 corrupts GRP78 phase behavior in brain endothelial cells, sustaining IRE1α–TRAF2–JNK signaling and driving apoptosis, tight junction loss, and blood–brain barrier failure in cerebral amyloid angiopathy. Pharmacological IRE1α inhibition restores vascular integrity, reduces leakage, and improves functional outcomes, revealing a targetable ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Conserved and Plant-Unique Strategies for Overcoming Endoplasmic Reticulum Stress

Frontiers in Plant Science, 2014
Stress caused by environmental conditions or physiological growth can lead to an accumulation of unfolded proteins in the endoplasmic reticulum (ER) causing ER stress, which in turn triggers a cytoprotective mechanism termed the unfolded protein response

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

Advanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.
