Neuron‐Derived Vesicular circMagi1 Restrains Vascular Repair After Ischemic Stroke by Promoting TRIM65‐Mediated ANXA2 Degradation

Advanced Science, EarlyView.
After ischemic stroke, injured neurons transfer circMagi1 to endothelial cells through extracellular vesicles. Within endothelial cells, circMagi1 binds ANXA2 and enhances its engagement with TRIM65, promoting ANXA2 ubiquitination and proteasomal degradation to constrain angiogenic repair.

Thalidomide-Based PROTACs: A Viable Strategy Against Trypanosomatids?

Drugs and Drug Candidates
Background: In recent years, compounds known as Proteolysis Targeted Chimeras (PROTACs) have revitalized the field of bioactive molecule design. These compounds promote proteolysis of therapeutic targets by recruiting them to ubiquitin ligases.

Degrading GPX4 via Biomimetic Nanoparticle‐Mediated In Situ Synthesis of Deep‐Learning‐Designed Binder‐Degron Chimeras for Prostate Cancer Therapy

Advanced Science, EarlyView.
A deep‐learning‐designed binder is fused to a combinatorial degron to create a binder‐degron chimera (bdC) that recruits the CUL2‐RING ubiquitin ligase complex. Encapsulation in a prostate‐cancer‐targeted, CD47‐camouflaged nanocarrier enables tumor‐specific in situ bdC expression, triggering GPX4 degradation and ferroptosis, thereby establishing a ...

Peptides, specific proteolysis products, as molecular markers of allergenic proteins - in silico studies.

Acta scientiarum polonorum. Technologia alimentaria, 2014
The objective of this study was to analyse allergenic proteins by identifying their molecular biomarkers for detection in food using bioinformatics tools. The protein and epitope sequences were from BIOPEP database, proteolysis was simulated using BIOPEP program and UniProt database screening via BLAST and FASTA programs.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

Advanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

Advanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.
