MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

High‐Throughput Formation of Pre‐Vascularized hiPSC‐Derived Hepatobiliary Organoids on a Chip via Nonparenchymal Cell Grafting

Advanced Science
Liver organoids have been increasingly adopted as a critical in vitro model to study liver development and diseases. However, the pre‐vascularization of liver organoids without affecting liver parenchymal specification remains a long‐lasting challenge ...

IKKβ and USP28 Regulate HEY1 Stability to Promote Cancer Stemness and Immune Evasion in Hepatocellular Carcinoma

Advanced Science, EarlyView.
The uncovered IKKβ‐USP28‐HEY1 axis fuels cancer stemness and immune evasion in hepatocellular carcinoma. USP28 deubiquitinates HEY1 upon IKKβ‐mediated phosphorylation, conferring PD‐1/PD‐L1 blockade resistance. Pharmacological inhibition of USP28 sensitizes resistant tumors to anti‐PD‐1 immunotherapy, revealing a promising therapeutic strategy ...

mTORC2 Phosphorylation of GSDME‐N Drives Cullin4B‐Mediated Proteasomal Degradation to Suppress Pyroptosis and Confer Radioresistance in Small Cell Lung Cancer

Advanced Science, EarlyView.
Radioresistance severely limits the efficacy of therapies for small cell lung cancer (SCLC). This study reveals a novel mechanism of resistance driven by the active suppression of pyroptosis. Specifically, the mTORC2 complex directly phosphorylates GSDME‐N and promotes its CUL4B‐mediated ubiquitination and proteasomal degradation.

Imaging‐Guided Live Single‐Cell Lipid Profiling of Leader and Follower Cells During Collective Migration of Triple‐Negative Breast Cancer Cells

Advanced Science, EarlyView.
Integrated single‐cell mass spectrometry reveals distinct lipidomic signatures that differentiate leader and follower phenotypes in migratory breast cancer cells. Phenotype‐specific alterations across various lipid classes, including fatty acids and phosphatidylcholines, underpin functional heterogeneity.

CEBPG‐Mediated Palmitic Acid Adaptation of Cancer‐Associated Fibroblasts Drives Metastasis of Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study reveals a metabolic signaling axis in the OSCC microenvironment where palmitic acid (PA) drives the activation of CAFs. PA uptake triggers CEBPG‐dependent epigenetic remodeling to upregulate ERN1 and TMBIM6, thereby mitigating ER stress. This adaptive program sustains CAF survival and the pro‐metastatic phenotype, establishing this pathway ...

Melatonin Alleviates Graft Biliary Fibrosis by Inhibiting VIM+ Cholangiocyte Subcluster via Hypoxia/TGF‐β‐CREM‐VIM Axis

Advanced Science, EarlyView.
Single‐cell RNA sequencing verified the presence of the VIM+ biliary epithelial cell (BEC) in the bile ducts of NAS patients. The hypoxia/TGF‐β‐CREM‐VIM axis mediated phenotypic switch toward VIM+ BEC is validated using a hypoxia/TGF‐β‐stimulated cellular model, a rat liver transplantation model, BEC‐specific Crem conditional knockout rats, and BEC ...

PDIA6–SCD1 Axis Rewires Lipid Metabolism to Drive Gastric Cancer Progression

Advanced Science, EarlyView.
Protein disulfide isomerase A6 (PDIA6) is identified as an oncogenic driver in gastric cancer. PDIA6 directly binds and stabilizes SCD1 by limiting its ubiquitin–proteasome‐mediated degradation, thereby sustaining monounsaturated fatty acid (MUFA)‐enriched lipid homeostasis and lipid metabolic reprogramming.

A Periosteum‐Inspired Janus Piezoelectric Scaffold Using Bioenergetic‐Driven H‐Type Vascularization for Diabetic Bone Regeneration

Advanced Science, EarlyView.
A periosteum‐inspired Janus piezoelectric scaffold converts micromechanical forces into electrical signals and synergizes with controlled resveratrol release. This dual action reprograms endothelial metabolism, drives H‑type vessel formation, and restores bone–vessel coupling in diabetic bone defects.
