Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

CircSMEK1 Suppresses HCC via the hnRNPK‐IGF2‐AKT Axis: A Diagnostic Biomarker and Therapeutic Target

open access: yesAdvanced Science, EarlyView.
CircSMEK1 is downregulated in MASH/HCC and predicts poor prognosis. It suppresses tumor progression by promoting hnRNPK ubiquitination and inhibiting the IGF2/PI3K/AKT axis, while its loss activates immunosuppressive cancer‐associated fibroblasts. Serum circSMEK1 serves as a non‐invasive diagnostic biomarker, and its restoration potently inhibits HCC ...

Microglial Deletion of Hrh4 Alleviates Alzheimer's Disease Pathologies by Enhancing Microglial Phagocytosis of Amyloid‐β and Tau

open access: yesAdvanced Science, EarlyView.
Histamine H4 receptor (H4R) antagonist VUF6002 mimics low‐dose X‐ray irradiation in aged Alzheimer's disease (AD) mice, enhancing microglial clearance of amyloid‐beta/hyperphosphorylated tau aggregates and restoring cognition. Microglial H4R deletion activates cAMP/TGF‐β1/Smad3 pathway, enhancing phagocytosis, while TGF‐β receptor 1 deletion abolishes ...

Gut Microbial Genetic Variation Prolongs Host Healthy Longevity and Remodels Metabolome and Proteome in Drosophila Melanogaster

open access: yesAdvanced Science, EarlyView.
This study reveals that specific genetic variations in gut‐residing Saccharomyces cerevisiae significantly extend healthspan and lifespan in Drosophila melanogaster. These mutants rejuvenate aged intestinal metabolism, upregulate mitochondrial proteins, and enhance energy pathways.
