Mitochondrial CircRNA CircMT‐RNR2 Safeguards Antioxidant Defense to Support Fibroblast Functions in Wound Repair

Advanced Science, EarlyView.
CircMT‐RNR2 promotes wound healing by enhancing fibroblast proliferation, migration, contraction, and extracellular matrix (ECM) production. It sustains mitochondrial redox balance by stabilizing the antioxidant protein PRDX3, thereby reducing ROS‐induced damage. In diabetic foot ulcers, hypoxia, hyperglycemia, and reduced FGF2 and EGF expression lower

Arabidopsis Bax Inhibitor-1 inhibits cell death induced by pokeweed antiviral protein in Saccharomyces cerevisae

Microbial Cell, 2015
Apoptosis is an active form of programmed cell death (PCD) that plays critical roles in the development, differentiation and resistance to pathogens in multicellular organisms. Ribosome inactivating proteins (RIPs) are able to induce apoptotic cell death

Synergistic Tuning of Conformational Dynamics, Electron Tunneling, and Substrate Positioning Enhances Electron Transfer in a P450 Chimera for Calcifediol Biosynthesis

Advanced Science, EarlyView.
A synergistic electron transfer (ET) optimization strategy modulating conformational dynamics, ET pathway, and substrate orientation is proposed for self‐sufficient cytochrome P450s. Guided by this strategy, a P450 variant with improved ET and catalytic efficiency was identified, and the underlying molecular basis was revealed by computational analysis.

Targeting DAP5 Disrupts Alternate Mode of Translational Initiation in Tregs and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
Regulatory T cells (Tregs) suppress antitumor immunity. This study identifies that the translation scaffold DAP5/eIF4G2 is upregulated in tumor‐infiltrating Tregs (ti‐Tregs). DAP5 mediates an alternate translation mode to sustain CD25 and MCL‐1 expression, which is critical for ti‐Treg stability and survival in the tumor microenvironment.

Cascade Therapy of Periodontitis via Sequential Release of Ribosome‐Targeting Antimicrobial Peptide and Irisin From a Multifunctional MOF‐Based System

Advanced Science, EarlyView.
This study presents a novel strategy for periodontitis treatment by co‐delivering a membrane‐ and ribosome‐targeting antimicrobial peptide GF and Irisin through a pH‐responsive metal‐organic framework. The system enables sequential release, providing rapid antibacterial action, anti‐inflammatory and antioxidative effects, as well as promoting bone ...

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

Advanced Science, EarlyView.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...
