Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

Advanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

Chemotherapy‐Activated GSK3β‐DNMT1 Signaling Upregulates CD47 to Evade Macrophage Phagocytosis and Drive Temozolomide Resistance in Glioblastoma

Advanced Science, EarlyView.
Temozolomide treatment activates GSK3β, driving DNMT1 phosphorylation, destabilization, and CD47 promoter hypomethylation in glioblastoma. This epigenetic shift upregulates CD47, enabling TMZ‐treated GBM cells to evade macrophage phagocytosis, survive chemotherapy, and acquire resistance.

Deubiquitination of Vangl by USP6 and USP32 Regulates Planar Cell Polarity Signaling

Advanced Science, EarlyView.
Compartment‐specific deubiquitination controls Vangl dosage and planar cell polarity signaling. USP6 and USP32 regulate distinct subcellular pools of Vangl by removing distinct ubiquitin modifications from Vangl proteins. This regulatory mechanism safeguards PCP‐dependent embryonic morphogenesis, while aberrant USP32‐dependent stabilization of VANGL ...

Protocol to investigate the biochemical details of immune checkpoint ligand/receptor ubiquitination using in vitro ubiquitination assay

The activity and stability of immune checkpoint ligands/receptors including PD-L1 and PD-1 are tightly regulated by ubiquitination. Biochemical analysis of their ubiquitination using in vitro enzymatic assays represents an indispensable technique for ...

The TUBA1B–G3BP2 Axis Sustains p65 Transcriptional Activity to Promote Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
TUBA1B is consistently upregulated in hepatocellular carcinoma and sustains malignant progression by stabilizing G3BP2. By restraining TRIM25‐associated K48‐linked ubiquitination, TUBA1B preserves the G3BP2–IκBα complex and basal NF‐κB/p65 activity. Concurrent TUBA1B/G3BP2 upregulation identifies an aggressive HCC subgroup with enhanced p65 activation ...

Cancer‐Associated Fibroblasts Promote Glucose Metabolic Reprogramming and Progression of Triple‐Negative Breast Cancer via Exosomal circFAD104‐Mediated Intercellular Communication

Advanced Science, EarlyView.
CAF‐derived exosomes deliver circFAD104 into TNBC cells, where it acts as a molecular scaffold that bridges the E3 ligase MARCHF8 and PGM1, promoting MARCHF8‐mediated K48‐linked ubiquitination and proteasomal degradation of PGM1. Loss of PGM1 redirects glucose‐phosphate flux from glycogen synthesis toward glycolysis, thereby driving stemness, EMT, and ...

Epigenetic Reactivation of TNFRSF19 Suppresses Mitophagy and Sensitizes Triple‐Negative Breast Cancer to Doxorubicin

Advanced Science, EarlyView.
TNFRSF19 is an epigenetically silenced regulator of mitophagy in triple‐negative breast cancer. TNFRSF19 deficiency activates the TGFBR1–SMAD3–PINK1 axis to promote mitophagy and confer doxorubicin resistance, whereas decitabine‐mediated restoration of TNFRSF19 suppresses mitophagy and enhances doxorubicin sensitivity, revealing a targetable epigenetic–

Near‐Infrared Fluorescent PROTAC Enables Theranostic Imaging and Selective Tau Degradation in Alzheimer's Disease

Advanced Science, EarlyView.
Here, we report a novel NIR fluorescent PROTAC platform that enables real‐time imaging and targeted degradation of Alzheimer's p‐Tau. Our lead compound effectively clears p‐Tau, reduces APP/Aβ, and alleviates cognitive deficits in AD mice. This work demonstrates a theranostic strategy for visualizing degradation and developing next‐generation AD ...

Molecular Glue Degraders Enhance CAPRIN1‐Dependent Lysosomal Degradation of APP and Reduce Amyloid β in Alzheimer's Disease

Advanced Science, EarlyView.
A new class of lysosome‐directed molecular glue degraders selectively enhance CAPRIN1–APP interactions, driving APP degradation and reducing amyloid‐β production in human neurons and Alzheimer's disease mouse models. This CAPRIN1‐dependent targeted protein degradation strategy reveals a previously unrecognized therapeutic approach for disrupting the ...

Targeting the CRYAB/β‐Catenin Axis with an MMP‐9‐Responsive Hydrogel Disrupts CTC Clusters to Suppress Progression of Hepatocellular Carcinoma after Radiofrequency Ablation

Advanced Science, EarlyView.
The graphical abstract illustrates that sublethal thermal stress after iRFA upregulates the chaperone CRYAB in residual HCC cells, which stabilizes β‐catenin and drives a dual pathological program, including EMT and N2‐TAN polarization, thereby leading to heterotypic CTC cluster formation. The MMP‐9‐responsive hydrogel (XB@Gel) delivers XAV‐939 and BMS‐
