Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

open access: yesAdvanced Science, EarlyView.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Advanced Biomaterial Delivery of Hypoxia‐Conditioned Extracellular Vesicles (EVs) as a Therapeutic Platform for Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This research introduces a novel approach to enhance neuroregeneration following Traumatic Brain Injury (TBI). Extracellular Vesicles (EVs) are isolated from human neural progenitor cells under hypoxic conditions, leading to enhanced expression of neurogenic and angiogenic factors.

The Mitochondrial Protein RESISTANCE to APHIDS 9 Interacts with S40 to Resist Aphid Infestation by Modulating Reactive Oxygen Species Homeostasis in Maize (Zea mays)

open access: yesAdvanced Science, EarlyView.
This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

Microwave‐Activated Bacterial Biorobot for Multimodal Cancer Therapy

open access: yesAdvanced Science, EarlyView.
An Escherichia coli bacterial biorobot is engineered for localized microwave activation in cancer therapy. Upon activation at tumor sites, the biorobot releases glucose oxidase, inducing tumor cell death via glucose depletion and H2O2 generation catalyzed by Cu2O.

Draper‐ATG3 Interaction Positively Regulates Autophagy to Mediate Silk Gland Degradation in Bombyx mori

open access: yesAdvanced Science, EarlyView.
Draper is evolutionarily conserved across most insect species. Loss of Draper inhibits autophagy activation, delaying middle silk gland degradation in the silkworm during metamorphosis. Draper interacts with autophagy ‐ related protein 3 (ATG3) to orchestrate autophagosome formation—a process essential for silk gland degradation during the larval‐pupal

Decoding Dental Stem Cell Aging: Mechanisms, Therapeutic Strategies, and Beyond

open access: yesAdvanced Science, EarlyView.
Dental stem cell (DSC) aging involves genomic instability, mitochondrial dysfunction, telomere attrition, and epigenetic alterations, leading to impaired proliferation, reduced differentiation potential, and pro‐inflammatory secretory activity. These processes drive cellular senescence and compromise regenerative and immunomodulatory functions, thereby

Honeysuckle‐Derived Nanovesicles Regulate Gut Microbiota for the Treatment of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
This study explores honeysuckle‐derived nanovesicles (HNVs) for treating inflammatory bowel disease. Orally administered HNVs alleviates colitis in mice by repairing the gut barrier, reducing inflammation, and restoring a healthy gut microbiota.

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.
