Spatial Transcriptomics and snRNA‐seq Expose CAF Niches Orchestrating Dual Stromal‐Immune Barriers in Hepatocellular Carcinoma

Advanced Science, EarlyView.
HmmyCAFs may form a triple immunosuppressive niche: possibly secrete ECM (POSTN, etc.) as physical barriers to block CD8⁺ T cells, induce CD8⁺ T exhaustion via those molecules, and use HIF‐1α‐driven metabolism to create acidic, nutrient‐poor microenvironments that suppress T cells.

Mechanisms of Direct Electron Transfer Governed by Redox‐Active Conductive Carrier with Superior Wettability in Anaerobic Biofilms

Advanced Science, EarlyView.
A redox‐active conductive carrier of tannic acid‐modified iron‐biochar with superior wettability is demonstrated to regulate direct electron transfer at the anaerobic biofilm‐carrier interface by enhancing the cytochrome c‐mediated pathway. For the first time, integrated evidence from spectroscopy, electrochemical analyses, and metatranscriptomics ...

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

Advanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.
