Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

LMO7 Suppresses Tumor‐Associated Macrophage Phagocytosis of Tumor Cells Through Degradation of LRP1

open access: yesAdvanced Science, EarlyView.
LMO7 in tumor‐associated macrophages suppresses phagocytosis of tumor cells and limits cytotoxic T lymphocytes infiltration, fostering tumor progression. Mechanistically, LMO7 mediates the ubiquitination and degradation of the phagocytic receptor LRP1, impairing its ability to engulf tumor cells and driving macrophages toward an antitumor phenotype ...

XIAP Stabilizes DDRGK1 to Promote ER‐Phagy and Protects Against Noise‐Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
Mechanism of GAS‐mediated protection against noise‐induced hearing loss (NIHL). Noise exposure activates the ATF4/eIF2α axis, downregulating XIAP and promoting DDRGK1 degradation, thereby inhibiting ER‐phagy and leading to hair cell (HC) death. GAS treatment rescues XIAP and DDRGK1 expression, reactivating ER‐phagy to mitigate HC loss, synaptic damage,

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

open access: yesAdvanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...

Aberrant SUMOylation Restricts the Targetable Cancer Immunopeptidome

open access: yesAdvanced Science, EarlyView.
Pharmacological SUMOylation inhibition (SUMOi) counteracts tumor immune evasion by unmasking an immunogenic HLA‐I peptide and neoepitope repertoire. By restoring HLA‐I ligand availability through increased antigen processing and presentation, enhanced proteasomal cleavage, and modulated TAP1 peptide affinity, SUMOi boosts tumor immunogenicity ...

Elemene Augments the Effects of Anti‐PD‐1 Immunotherapy on Hepatocellular Carcinoma by Regulating the miR‐130a‐5p/SPP/MHC‐I Axis

open access: yesAdvanced Science, EarlyView.
Elemene increases SPP expression by competitively binding with miR‐130a‐5p to suppress SPP mRNA degradation. This led to more antigen/MHC‐I complexes being expressed on the cell surface, which consequently facilitated the recognition and killing of HCC cells by CTLs and enhancing the antitumor immune efficacy of anti‐PD‐1.
