Targeting PTBP3‐Mediated Alternative Splicing of COX11 Induces Cuproptosis for Inhibiting Gastric Cancer Peritoneal Metastasis

Advanced Science, EarlyView.
The splicing factor PTBP3 promotes COX11 exon skipping, allowing gastric cancer organoids to evade cuproptosis. Antisense oligonucleotide drugs targeting PTBP3‐mediated COX11 alternative splicing, in combination with copper ionophores, promote cuproptosis in organoids, thereby providing a therapeutic approach for gastric cancer peritoneal metastasis ...

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

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.

Mutants of Taq DNA polymerase resistant to PCR inhibitors allow DNA amplification from whole blood and crude soil samples [PDF]

, 2008
Potent PCR inhibitors in blood and soil samples can cause false negative results from PCR-based clinical and forensic tests. We show that the effect of these inhibitors is primarily upon Taq DNA polymerase, since mutational alteration of the polymerase ...

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.

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]

, 2005
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).

Virome and Experimental Analysis Reveal Tryptophan‐Like Dissolved Organic Matter Contributes to the Persistence of Plant Viruses in River Water

Advanced Science, EarlyView.
Tryptophan‐like dissolved organic matter (Try‐like DOM), a key component of organic matter in river ecosystems, demonstrates significant protective effects against plant viruses. The protective mechanism operates via a “swimming firewall” mode, whereby free Try‐like DOM attenuates ultraviolet (UV) radiation and scavenges reactive oxygen species ...
