Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

Advanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

C(sp3)─S Bond Formation via the Synergy of Oxidative With Reductive Photocatalysts Through Photoredox and Dual Hydrogen Atom Transfer Processes

Advanced Science, EarlyView.
The research reveals that polysulfide anions (K2Sx), which serve as reducing catalysts, can also effectively act as sulfur reagents, providing the formation of C(sp3)─S bonds through photoredox catalysis with an oxidative photocatalyst tetrabutylammonium decatungstate (TBADT) and dual hydrogen atom transfer (DHAT) process.

Mechanisms and evolution of oxidative sulfur metabolism in green sulfur bacteria

Frontiers in Microbiology, 2011
Green sulfur bacteria (GSB) constitute a closely related group of photoautotrophic and thiotrophic bacteria with limited phenotypic variation. They typically oxidize sulfide and thiosulfate to sulfate with sulfur globules as an intermediate.

A Mitochondria‐Targeted Nanozyme Platform for Multi‐Pathway Tumor Therapy via Ferroptosis and Cuproptosis Regulation

Advanced Science, EarlyView.
This work reports a mitochondria‐targeted nanozyme platform, MIL‐Cu1.8S‐TPP/FA, which induces potent cuproptosis via localized delivery of Cu1.8S nanodots to mitochondria. Surface‐anchoring these nanodots onto MIL‐88B metal‐organic frameworks enhances both passive and active tumor targeting.

Sulfur starvation-induced autophagy in Saccharomyces cerevisiae involves SAM-dependent signaling and transcription activator Met4

Nature Communications
Autophagy is a key lysosomal degradative mechanism allowing a prosurvival response to stresses, especially nutrient starvation. Here we investigate the mechanism of autophagy induction in response to sulfur starvation in Saccharomyces cerevisiae.

Comparative Analysis of Clinical Outcomes and Financial Aspects of Phototherapies and Immunotherapy for Cancer

Advanced Science, EarlyView.
This review compares clinical outcomes, translational progress, and global funding trends across cancer phototherapies—photodynamic, photothermal, and photoimmunotherapy—and conventional immunotherapy. It highlights differences in treatment efficacy, clinical trial status, financial investment, and regulatory challenges, providing a comprehensive ...

Weight Cycling Deregulates Eating Behavior in Mice via the Induction of Durable Gut Dysbiosis

Advanced Science, EarlyView.
Weight cycling in Humans is suspected to dysregulate eating behavior. Mice submitted to body weight cycling by alternating western‐type and regular chow diets display increased hedonic appetite when exposed to a palatable diet, reminiscent of binge‐eating episodes.
