Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

open access: yesAdvanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

POLE Deficiency Exacerbates Diesel Engine Exhaust‐Induced Genomic Instability and Malignant Transformation of Bronchial Epithelial Cells

open access: yesAdvanced Science, EarlyView.
This study establishes a diesel engine exhaust (DEE)‐induced malignant transformation model in bronchial epithelial cells. Whole genome sequencing(WGS) and RNA‐seq reveal DEE‐induced mutational signatures and gene expression profiles. Mechanistically, DEEaffect polymerase epsilon (POLE) and mismatch repair, driving genomic instability and promoting ...

The DEC2‐SCN2A Axis is Essential for the Anticonvulsant Effects of Cannabidiol by Modulating Neuronal Plasticity

open access: yesAdvanced Science, EarlyView.
This study identifies DEC2 as a critical transcriptional repressor of Scn2a that directly binds E‐box motifs in its promoter to regulate neuronal plasticity and epileptogenesis. Functional manipulation of DEC2 alters seizure susceptibility in vivo. Cannabidiol enhances this repression, unveiling a novel DEC2‐SCN2A axis underlying its anticonvulsant ...

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

open access: yesAdvanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Okanin Suppresses the Growth of Colorectal Cancer Cells by Targeting at Peroxiredoxin 5

open access: yesAdvanced Science, EarlyView.
Okanin suppresses colorectal cancer growth by directly targeting PRDX5. This natural compound selectively binds peroxiredoxin 5 (PRDX5), inhibiting its activity and inducing WSB1‐mediated degradation. PRDX5 loss elevates ROS, suppresses GPX4 via SIAH2, and further triggers cell death (apoptosis and ferroptosis).
