Nuclear‐Localized BCKDK Facilitates Homologous Recombination Repair to Support Breast Cancer Progression and Therapy Resistance

Advanced Science, EarlyView.
Under DNA damage, tumor cells rely on efficient DNA repair for survival and therapy resistance. This study has demonstrated that BCKDK localizes to breast cancer cell nuclei, where it binds to and phosphorylates RNF8, thereby blocking ubiquitin‐mediated degradation of RAD51 and enhancing HRR. A selective BCKDK inhibitor synergizes with clinical agents,

An Engineered PfAgo with Wide Catalytic Temperature Range and Substrate Spectrum

Advanced Science, EarlyView.
This work presents a strategy for engineering thermophilic Ago proteins to obtain wide catalytic temperature range and broad substrate spectrum. This strategy is applied to engineer PfAgo and TtdAgo, and the biochemical properties of the engineered PfAgo are systematically characterized. The study further elucidates the structural differences involved.

Small RNA Toxin‐Assisted Evolution of GC‐Preferred ErCas12a for Enhanced Genome Targeting Range

Advanced Science, EarlyView.
ErCas12a is engineered to target GC‐rich PAMs using a small RNA toxin‐aided positive screening system. The resulting variant, enErCas12a, exhibits an expanded PAM profile and facilitates efficient gene editing in both bacterial and mammalian cells, while preserving high targeting specificity for both canonical and non‐canonical PAM targets.

Enhanced the Trans‐Cleavage Activity of CRISPR‐Cas12a Using Metal‐Organic Frameworks as Stimulants for Efficient Electrochemical Sensing of Circulating Tumor DNA

Advanced Science, EarlyView.
This work designs manganese metal‐organic frameworks (Mn‐MOFs) co‐assembled with Cas12a/crRNA, enabling rapid release of Mn2⁺ under mild conditions. The MOFs‐induced proximity effect sustains Mn2⁺‐Cas12a/crRNA interactions, enhancing the trans‐cleavage activity of complex available to develop an electrochemical biosensor based on Mn‐MOFs‐enhanced ...

Aqueous Two‐Phase Submicron Droplets Catalyze DNA Nanostructure Assembly for Confined Fluorescent Biosensing

Advanced Science, EarlyView.
Submicron droplets, formed by a polyethyleneglycol (PEG)/dextran aqueous two‐phase system·(ATPS), can act as catalytic centers that concentrate DNA and accelerate assembly kinetic in crowded environments. It highlights a cooperative mechanism wherein global crowding from PEG induces an excluded volume effect, while local crowding from dextran provides ...

METTL14‐Induced M6A Methylation Increases G6pc Biosynthesis, Hepatic Glucose Production and Metabolic Disorders in Obesity

Advanced Science, EarlyView.
It is shown that obesity is associated with increases in hepatic METTL14 and m6A methylation of G6pc transcript. YTHDF1 and YTHDF3 bind to m6A‐marked G6pc mRNA to increase its synthesis. Hepatocyte‐specific deletion of Mettl14 decreases G6pc m6A methylation, G6pc biosynthesis, and G6pc‐mediated gluconeogenesis, alleviating glucose metabolic defects in ...
