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

Dual IRE1 targets: Determinants of the cell fate?
IRE1 is an ER stress sensor that restores protein homeostasis through two signaling activities: XBP1s, which upregulates its target gene expression or RIDD which downregulates its target transcripts. We recently identified Dual IRE1 Targets (DIT) which are modulated by both XBP1s and RIDD activities.

ABSTRACT Drought stress severely restricts rice productivity, necessitating strategies to enhance stress resilience. Here, we identify translation termination as a tunable regulatory node for stress adaptation. Using 25 rounds of SELEX, we isolated RTAR, an RNA aptamer that binds the rice eukaryotic release factor 1 (OseRF1) with nanomolar affinity ...

Understanding extracellular vesicles in antiaging
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Abstract PR12: Targeting eIF2α phosphorylation for cancer therapy
Solid tumor tumors contain hypoxic regions. Tumor hypoxia is co-present with reduced nutrients and usually intracellular acidification. Lack of O2 and nutrients, and intracellular acidification causes endoplasmic reticulum stress (ER).

Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

QRICH1 Suppresses Glioma Progression by Inducing ER Stress and Activating the PERK‐ATF4‐CHOP Pathway
ABSTRACT Background ER stress (ERS) influences tumor behavior through the unfolded protein response (UPR), yet its role in glioma is not fully defined. This study investigated the function of the ERS‐related regulator QRICH1 in glioma progression. Methods Public databases (TCGA and GTEx) were used to evaluate QRICH1 expression, survival, and prognostic
