Homocysteine Promotes the Pathogenesis of Atherosclerosis through the Circ‐PIAS1‐5/miR‐219a‐2‐3p/TEAD1 Axis

open access: yesAdvanced Science, EarlyView.
A model is schematically represented for the major molecular mechanisms by which homocysteine (Hcy) accelerates the nuclear export of circ‐PIAS1‐5, which regulates atherosclerosis by acting as a competing endogenous RNA for miR‐219a‐2‐3p. Hcy enrichment of circ‐PIAS1‐5 leads to YTHDC1 binding to circ‐PIAS1‐5 and promotes its intracellular localization ...

Development of MDM2‐Targeting PROTAC for Advancing Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This work presents a creative pipeline for developing MDM2‐targeting PROTACs (MDM2‐PROTACs) for application in bone regeneration. The developed PROTACs (CL144 and CL174) are validated for their degradation efficiency and osteogenic effects in human BMSCs.

SSRP1/SLC3A2 Axis in Arginine Transport: A New Target for Overcoming Immune Evasion and Tumor Progression in Peripheral T‐Cell Lymphoma

open access: yesAdvanced Science, EarlyView.
Enhanced arginine uptake is a critical feature of metabolic reprogramming in PTCL, characterized by elevated expression of the arginine transporter SLC3A2. SLC3A2‐mediated arginine uptake facilitates PTCL proliferation and survival by enhancing OXPHOS metabolism and inducing immune evasion.

PLXDC1+ Tumor‐Associated Pancreatic Stellate Cells Promote Desmoplastic and Immunosuppressive Niche in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
This study uncovers the activation, heterogeneity, and regulatory roles of pancreatic stellate cells (PSCs) at single‐cell and spatial levels. It further identifies PLXDC1+ PSCs near aggressive LRRC15+ cancer‐associated myofibroblasts and SPP1+ macrophages, forming a desmoplastic and immunosuppressive tumor niche that promotes CD8+ T cell exhaustion ...

Mechanisms of Baicalin Alleviates Intestinal Inflammation: Role of M1 Macrophage Polarization and Lactobacillus amylovorus

open access: yesAdvanced Science, EarlyView.
Baicalin alleviates E. coli‐induced intestinal inflammation through dual mechanisms: direct inhibition of the TLR4/IRF/STAT signaling pathway to modulate macrophage polarization and antigen presentation, thereby regulating Th17/Treg cell differentiation; and microbiota‐mediated indirect effects via increasing Lactobacillus amylovorus abundance and ...

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

open access: yesAdvanced 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 ...

M2 Macrophage‐Derived Extracellular Vesicles Reprogram Immature Neutrophils into Anxa1hi Neutrophils to Enhance Inflamed Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study reveals that M2‐EVs mitigate periodontitis‐induced bone resorption by modulating neutrophil fate. Single‐cell RNA sequencing identified an Anxa1hi neutrophil subpopulation with pro‐reparative properties. M2‐EVs disrupt neutrophil maturation, promoting this subpopulation through key reprogramming genes (Acvrl1, Fpr2). These findings highlight

Discovery, Herbicidal Activity and Biosynthesis of a Novel Natural Tetramic Acid from Alternaria Species

open access: yesAdvanced Science, EarlyView.
The biosynthetic mechanism of novel natural tetramic acid S‐TeA in Alternaria alternata is elucidated. Threonine acts as a precursor for 2‐amino‐3‐methylhexanoic acid (AMHA) synthesis via eight key enzymes from the branched‐chain amino acid biosynthetic pathway in the mitochondrion, wherein three unique enzymes (IPMS, IPMDH, and ISMD) play critical ...
