Cars2‐Mediated Cysteine Catabolism Drives Brown Fat Development and Thermogenesis Through Persulfidating EBF2

Advanced Science, EarlyView.
We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

SIRT1 Prevents Ferroptosis in Corneal Epithelial Cells by Enhancing HIF1α Protein Stability in Dry Eye Disease

Advanced Science, EarlyView.
Hyperosmotic stress drives ferroptosis in corneal epithelium via SIRT1 downregulation. This work demonstrates that SIRT1 activation stabilizes HIF1α, which transcriptionally upregulates GPX4 to inhibit lipid peroxidation and cell death. The identified SIRT1/HIF1α/GPX4 axis reveals a novel defense mechanism and potential therapy for dry eye disease ...

Engineered TIGIT‐Blockade Membrane Vesicles Synergize with Microwave Ablation to Mediate Liver Metastases Eradication

Advanced Science, EarlyView.
Microwave ablation (MWA) represents a highly effective and clinically significant therapeutic modality for the treatment of liver metastases. This study develops engineered cell membrane vesicles to specifically target the transition zone of MWA for liver metastases. This strategy can inhibit VEGF‐mediated immunosuppression, block CD155/TIGIT signaling

GPX4 Inhibitor Resistance and Metastatic Features in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study establishes breast cancer cell lines that are resistant to glutathione peroxidase 4 inhibitors (GPX4i) in vitro and investigates the metastatic capacity of the GPX4i‐resistant versus parental lines in vivo. GPX4i‐resistant cells survive upon intravenous injection, but lose capacity to spontaneously metastasize.

ESCRT‐Mimetic Nanodegrader Targets STING for Anti‐Inflammatory Therapy

Advanced Science, EarlyView.
A nanoplatform‐enabled targeted protein degradation strategy is presented to regulate aberrant STING signaling. STING‐ATTEC induces selective autophagic degradation of STING via formation of a STING–ATTEC–LC3 ternary complex, while the cationic FA‐LNP+ system enhances LC3 generation and targeted delivery. Together, this synergistic approach efficiently

Albumin‐Bound STING Agonist Reprograms HSPCs to Antitumor Neutrophils Enhancing CD8+ T Cell Immunity

Advanced Science, EarlyView.
This study demonstrates that an albumin‐bound STING agonist (Nano ZSA‐51D) reprograms HSPCs to produce antitumor neutrophils with enhanced MHC I–mediated CD8+ T cell activation, thereby sensitizing tumors to α‐PD1 therapy. These findings highlight a strategy to target early hematopoiesis for shaping neutrophil fate and potentiating cancer immunotherapy.

Smartly Assembled near‐Micron RF‐Responsive Agents Bridge Transarterial Embolization and Immunothermal Potentiation

Advanced Science, EarlyView.
ABSTRACT Hepatocellular carcinoma (HCC) remains a significant clinical challenge due to the limited efficacy of conventional treatments like surgery, radiofrequency ablation (RFA), and transarterial embolization (TAE). Here, we develop an innovative TAE and immunothermal therapy strategy based on smartly assembled near‐micron layered double hydroxide ...

Redox‐Responsive Polymeric Nanocapsules for Enhanced Tumor‐Targeted Delivery of Antimicrobial Peptides

Advanced Science, EarlyView.
This study presents a modular redox‐responsive nanocapsule platform that enables enhanced tumor‐targeted delivery of antimicrobial peptides. Using melittin as an example, the system achieves controlled activation within the tumor microenvironment, improving intratumoral accumulation while minimizing systemic toxicity.
