Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

Advanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

Advanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.
