Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

open access: yesThe FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

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.

ATF4 transcriptional activities during UPR are Siah1/2-dependent.

open access: yes, 2014
(A) Siah2 expression augments ATF4 protein levels. WT MEFs were transfected either with control or Siah2 expression vectors, and 24 h later the cells were collected. Harvested proteins were analyzed for ATF4, Siah2 and β-actin.

One day of environment‐induced heat stress causes injury to the murine kidney

open access: yesExperimental Physiology, EarlyView.
Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Targeting ATF4 alters SOD1 aggregation in mutant SOD1 transgenic mice.

open access: yes, 2013
Histological characterization of ATF4−/−/SOD1G86R spinal cord. (A) Immunofluorescence analysis of NeuN and Olig2 staining in spinal cord tissue derived from ATF4+/+, ATF4+/+/SOD1G86R and ATF4−/−/SOD1G86R at the late disease stage.

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

open access: yesJournal of Applied Toxicology, Volume 46, Issue 8, Page 2599-2622, August 2026.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Transcriptional regulation of ATF4 is critical for controlling the Integrated Stress Response during eIF2 phosphorylation

open access: yes, 2012
Indiana University-Purdue University Indianapolis (IUPUI)In response to different environmental stresses, phosphorylation of eIF2 (eIF2P) represses global translation coincident with preferential translation of ATF4.

Role of ATF4 in fibroblast proliferation and apoptosis induced by mechanical trauma through the miR−93-3p/Smad7 axis

open access: yesStress
Stress urinary incontinence (SUI) is a serious disease for females. This study attempts to explore the role of activating transcription factor 4 (ATF4) in mechanical trauma-induced SUI fibroblast cell proliferation and apoptosis, thereby finding a ...

Mitochondrial membrane remodeling in stress adaptation: Lipid control of organelle quality

open access: yesProtein Science, Volume 35, Issue 8, August 2026.
Abstract Mitochondria respond to proteotoxic stress through the mitochondrial unfolded protein response, traditionally viewed as a transcriptional program that restores proteostasis by inducing chaperones and proteases. Emerging evidence indicates that mitochondrial membrane remodeling constitutes an additional adaptive component of this response ...
