Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

open access: yesAdvanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Gut Microbiota‐Derived Anandamide Mediates the Therapeutic Effects of Urolithin A on Alcohol‐Induced Cognitive and Social Dysfunction via CB1R‐DRD2‐RAP1 Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier

open access: yesAdvanced Science, EarlyView.
SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

ZNRD2 Mediated Nucleoprotein Aggregation Impairs Respiratory Syncytial Virus Replication

open access: yesAdvanced Science, EarlyView.
During RSV infection, nucleoprotein (N) forms RNA‐bound oligomers. The host protein ZNRD2 binds to these oligomers, promoting their transition into insoluble aggregates. These aggregates simultaneously sequester functional N to restrict viral production and disrupt chaperonin assembly quality control by interfering with ZNRD2's role as an adaptor ...
