An Insulin‐Exosome‐TNFAIP8 Axis Drives Stromal Fibrosis and Therapeutic Resistance in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic ductal adenocarcinoma (PDAC), insulin is associated with activation of PI3K/AKT–RAB3A signaling and enhanced secretion of TNFAIP8‐enriched exosomes from tumor cells. Uptake of these exosomes by fibroblasts is linked to TRIM21‐dependent STAT1 degradation and the emergence of myofibroblastic CAF–associated features, accompanied by increased

Lipid‐Facilitated Opening of the ADAM10 Sheddase Revealed by Enhanced Sampling Simulations

Advanced Science, EarlyView.
Phosphatidylserine acts as a lipid trigger to enhance activation of the sheddase ADAM10. By integrating fluorescence spectroscopy assays with enhanced sampling molecular dynamics simulations, this study shows that phosphatidylserine promotes ADAM10 catalytic activity along with expansion of its extracellular domains, enhancing accessibility to scaffold

Decoding the Integrated Stress Response of Pancreatic Cancer: Identifying a Serine‐dependent Tumor Subset Under Metabolic Relationships With CAFs.

Advanced Science, EarlyView.
Researchers identified a pancreatic cancer subset with low global protein synthesis but heightened translation of stress‐response genes like ATF4, rendering cells resistant to chemotherapy and apoptosis. These tumors depend on serine and cysteine from surrounding cancer‐associated fibroblasts (CAFs), which shift to produce serine by curbing collagen ...

Alkaline Phosphatase‐Activated NIR‐II AIEgens Nanosystem for Surgical and Postoperative Closed‐Loop Therapy of Advanced Osteosarcoma

Advanced Science, EarlyView.
This study designed a tumor microenvironment‐responsive AIEgen nanoparticle for near‐infrared photoimmunotherapy, which inhibits primary tumors and metastasis by promoting pyroptosis and suppressing aerobic glycolysis. ABSTRACT In advanced osteosarcoma, tumor invasion often prevents complete resection, and immunotherapy is limited by the tumor's ...

Disulfide‐Bridged Ru Complex–Mediated Photo‐Disulfidptosis for Colorectal Cancer Therapy

Advanced Science, EarlyView.
In this work, a binuclear ruthenium complex, RuSSRu was developed for efficient colorectal cancer (CRC) treatment. The synergistic interaction between disulfidptosis and lysosomal damage‐induced apoptosis induced by RuSSRu amplified tumor cell death. This innovative approach offers a potent therapeutic strategy for CRC.
