A Modular DNAzyme for Precise Visualization and Intervention of Alternative Splicing Isoforms in Live Cells

Advanced Science, EarlyView.
A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

Purification and characterization of DNA ligase III from bovine testes. Homology with DNA ligase II and vaccinia DNA ligase.

The Journal of biological chemistry, 1995
Mammalian cell nuclei contain three biochemically distinct DNA ligases. In the present study we have found high levels of DNA ligase I and DNA ligase III activity in bovine testes and have purified DNA ligase III to near homogeneity. The high level of DNA ligase III suggests a role for this enzyme in meiotic recombination.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Antagonistic Ubiquitin Switching by USP7 and RNF40 Orchestrates KDM6A Homeostasis to License Coronavirus Susceptibility

Advanced Science, EarlyView.
We identify an antagonistic ubiquitin circuit that controls cellular permissiveness to multiple coronaviruses. The deubiquitinase USP7 stabilizes the epigenetic regulator KDM6A to upregulate viral receptors, while the E3 ligase RNF40 degrades KDM6A by catalyzing K6/K11‐ubiquitin chains of KDM6A for autophagic degradation.

A Functionally Conserved Enhancer is Critical for PGC1A Expression and Thermogenesis in Brown Fat

Advanced Science, EarlyView.
An evolutionarily conserved enhancer controls PGC1A expression and thermogenic activation in brown adipose tissue. Integrative multi‐omics analyses identify two BAT‐specific enhancers, with PGC1A‐En1 functioning as the dominant regulatory element that maintains thermogenic capacity across species.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in
