Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

open access: yesAdvanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.

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.

Heat Stress Modulates WDR5‐Mediated H3K4me3 Modification to Induce Melanogenesis via Activating CX3CL1/CX3CR1 Axis

open access: yesAdvanced Science, EarlyView.
This study elucidates the mechanism by which heat stress regulates skin pigmentation: heat stress upregulates CX3CL1 through the MYC‐WDR5‐H3K4me3 axis, thereby activating the CX3CL1/CX3CR1‐JNK signaling pathway and ultimately promoting melanogenesis. These findings provide novel potential therapeutic targets for pigmentary skin disorders.

Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

O/C Ratio‐Driven Fluorescence Enhancement in Cellulose‐Derived Carbon Quantum Dots: Mechanistic Insights into Reaction Pathways

open access: yesAdvanced Science, EarlyView.
Three types of CQDs are prepared from cellulose and its derivatives via hydrothermal carbonization. An increase in the atomic O/C ratio from 0.25 to 0.61 results in a nearly seven‐fold enhancement in QY. DFT calculations verify this mechanism. Further, this study elucidates the formation pathways of cellulose‐derived CQDs and proposes a fluorescence ...
