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 ...

This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Basal IKK activity is decreased in cells lacking IRE1.
(A) Cells lacking IRE1 have lower basal IKK activity. IRE1+/+ (closed circle) and ire1−/− (open circle) MEFs were treated with MG132 for up to 60 min, and P-IκBα, total IκBα, and actin were measured by Western Blot.

As an endoplasmic reticulum (ER) stress sensor, inositol-requiring enzyme 1 (IRE1) splices the bZIP60 mRNA, and produces an active bZIP60 transcription factor that regulates genes involved in the unfolded protein response (UPR) during ER stresses.

Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration
This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

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

Computer-aided peptide-based drug design for inositol-requiring enzyme 1
Inositol-requiring enzyme 1 (IRE1), an endoplasmic reticulum (ER) transmembrane protein with both kinase and endoribonuclease activities, plays an essential role during ER stress and its subsequent unfolded protein response (UPR).
