Advanced Science, EarlyView.Multi‐omics analyses uncover breed‐specific cis‐regulatory landscapes and higher‐order chromatin architectural differences that underlie early postnatal muscle fiber divergence in pigs. A super‐enhancer upstream of PPP3CB recruits MEF2C to activate PPP3CB transcription, while the PPP3CB–MEF2C positive feedback loop promotes oxidative muscle fiber ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms
Advanced Science, EarlyView.Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System
Advanced Science, EarlyView.Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis
Advanced Science, EarlyView.In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.

Advanced Science, EarlyView.The TopCas platform utilizes an engineered DNA‐RNA chimeric circular crRNA to establish topology‐gated control over CRISPR‐Cas12a activity, enabling target‐triggered self‐catalytic amplification (preamplification‐free). This system seamlessly integrates highly sensitive molecular diagnostics with conditionally controlled gene editing, demonstrating ...

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform
Advanced Science, EarlyView.We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.

Mechanozyme: An Artificial Enzyme With a Mechanophore Framework
Advanced Science, EarlyView.Mechanical destabilization of a G‐quadruplex mechanophore in a DNAzyme markedly boosts its catalytic activity, demonstrating “mechanozymes” as artificial enzymes whose functions are modulated by mechanical stress exerted by ultrasonication. This mechanozyme principle is broadly applicable to control biomolecular activities.
