Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

CypD Dependent mPTP Opening Is Crucial for Oxidized Mitochondrial DNA Release in Ferroptosis

open access: yesAdvanced Science, EarlyView.
Ferroptosis is driven by mitochondrial permeability transition pore (mPTP) opening, which induces mitochondrial swelling and releases oxidized mitochondrial DNA. The released mtDNA activates cGAS–STING signaling, promotes ferritinophagy, and amplifies ferroptotic cell death. Disruption of mtDNA repair sensitizes tumors to ferroptosis in vivo, revealing

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.

Integrative clustering by colonic volatile fatty acids reveals microbiota and host physiological variation in weaned piglets

open access: yesJournal of Animal Science and Biotechnology
Background Volatile fatty acids (VFAs) reflect microbial fermentation linking gut microbiota, metabolism and host physiology. However, endogenous VFA profiles and their physiological relevance remain insufficiently characterized.

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

open access: yesAdvanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

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 ...

A Novel Function of Nonadecanoic Acid in Regulating Glucose Homeostasis

open access: yesAdvanced Science, EarlyView.
This study identifies the odd‐chain fatty acid C19:0 as an endogenous ligand of GPR120 that promotes glucose homeostasis via Gαq signaling. In obesity, elevated palmitic acid suppresses endogenous C19:0 production through a miRNA–PPARα–HACL1 pathway, offering a promising direction for understanding the role of OCFAs in human health.
