CRISPR in MOF Formulation with Enhanced Stability, Activity, and Altered PAM Specificity for Broad‐Spectrum Diagnosis of Bacterial Sepsis

open access: yesAdvanced Science, EarlyView.
CRISPR‐FLEXMO (CRISPR with flexible PAM in MOF encapsulation) integrates a PAM‐relaxed Cas12a K607R enzyme with a manganese‐coordinated MOF for broad‐spectrum diagnosis of bacterial sepsis. The MOF enhances activity and preserves functionality under heat, solvent, and chaotropic stress, supporting long‐term room‐temperature storage.

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

open access: yesAdvanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW

Synthesis, characterization, and antimicrobial activity of an ampicillin-conjugated magnetic nanoantibiotic for medical applications

open access: yesInternational Journal of Nanomedicine, 2014
Because of their magnetic properties, magnetic nanoparticles (MNPs) have numerous diverse biomedical applications. In addition, because of their ability to penetrate bacteria and biofilms, nanoantimicrobial agents have become increasingly popular for the

Synovial Fluid‐derived Micrococcus Luteus G18 Exacerbates Osteoarthritis Progression by Promoting Chondrocyte Degradation via TLR2/JNK/AP‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
Traditionally considered sterile, the articular cavity is now recognized to harbor microbial communities influencing osteoarthritis (OA). Integrating 16S rRNA sequencing and culturomics, Micrococcus luteus is enriched in advanced OA. Notably, M. luteus G18 exacerbates cartilage degeneration via TLR2/JNK/AP‐1‐mediated ECM disruption, revealing intra ...

HMGB2–RAD21 Axis Promotes Fibro/Adipogenic Progenitor Proliferation and Regulates Fat Infiltration

open access: yesAdvanced Science, EarlyView.
This study constructed the first developmental atlas of embryonic skeletal muscle fibro/adipogenic progenitors (FAPs) and identified an HMGB2+ FAPs subpopulation that regulates FAP pool size and muscle homeostasis. HMGB2 directly targets the RAD21 promoter, and its knockout significantly reduces FAP numbers, thereby lowering the potential for ...

Altering Enzymatic Activity: Recruitment of Carboxypeptidase Activity into an RTEM β-Lactamase/Penicillin-Binding Protein 5 Chimera [PDF]

open access: yes, 1990
The D-Ala-D-Ala carboxypeptidases/transpeptidases (penicillin-binding proteins, PBPs) share considerable structural homology with class A β-lactamases (EC 3.5.2.6), although these β-lactamases have no observable D-Ala-D-Ala carboxypeptidase activity ...

SUPER: Upcycling Genetic Parts for Precise Gene Expression Control, Leakage Minimization, and Genetic Circuit Stability

open access: yesAdvanced Science, EarlyView.
To precisely modulate natural and synthetic regulatory parts, SUPER is introduced as a sophisticated and tunable controller of genetic devices without requiring sequence modification on the target. SUPER enhances dynamic range of RNA‐, chemical‐, temperature‐, and protein‐responsive biosensors up to 1011%, and converts biosensors to cover an expanded ...
