NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

open access: yesAdvanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

open access: yesAdvanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Thermal Shielding and Vapor Transport Enhancement in MOF‐Enabled Membranes for Membrane Distillation

open access: yesAdvanced Science, EarlyView.
A metal–organic framework‐enabled membrane (MEM) with a hierarchical porous structure is developed for thermal‐efficient membrane distillation. By embedding ZIF‐8 onto PH nanofibers, the MEM achieves low thermal conductivity and significantly enhances vapor flux and thermal efficiency.

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

open access: yesAdvanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Homoisoflavanone Delays Colorectal Cancer Progression via DNA Damage‐Induced Mitochondrial Apoptosis and Parthanatos‐Like Cell Death

open access: yesAdvanced Science, EarlyView.
Homoisoflavanone (HIF), a bioactive compound isolated from Polygonatum kingianum, selectively suppresses colorectal cancer progression by inducing DNA damage‐mediated mitochondrial apoptosis and parthanatos‐like cell death. HIF triggers mitochondrial dysfunction, including depolarized membrane potential, elevated ROS, and ATP depletion, while impairing
