Single‐Molecule Characterization of Bacterial Factor‐Dependent Transcription Activation by Rob

Advanced Science, EarlyView.
Factor‐dependent transcription activation is crucial and involves complex interactions between transcription factors, RNA polymerase, and promoter DNA. Using single‐molecule assays, we show that Rob prebinds RNAP to facilitate promoter search and enhances DNA unwinding and promoter escape.

Autoantigen mRNA‐LNP Vaccination Drives Therapeutic Efficacy in Preclinical Models for Autoimmunity

Advanced Science, EarlyView.
Systemic and intramuscular delivery of autoantigen mRNA via lipid nanoparticles reprograms antigen‐presenting cells toward a mature, homeostatic state, driving antigen‐specific T cell exhaustion and providing therapeutic efficacy across autoimmune disease models.

EpCAM+ Extracellular Vesicle PD‐L1 Dynamics as a Predictive Biomarker of Immune Checkpoint Blockade Response

Advanced Science, EarlyView.
A highly sensitive SERS‐based platform measures PD‐L1 expression on EpCAM+ circulating EVs from cancer patients undergoing immunotherapy. Monitoring dynamic changes after treatment reveals that reduced EpCAM+ EV PD‐L1 levels associate with improved long‐term clinical outcomes, establishing a non‐invasive approach for tracking immune checkpoint ...

Optimization of biotinylated antibody and streptavidin-HRP.

, 2016
Two different dilutions of biotinylated antibody (1:500 and 1:1000) were coated onto ELISA plates. Different dilutions of streptavidin-HRP (1:1000, 1:5000, and 1:10000) were added and the interaction between biotinylated antibody and streptavidin-HRP was

Gene Correction Enhances Dopaminergic Cell Therapy in a Nonhuman Primate Model of Parkinson's Disease

Advanced Science, EarlyView.
LRRK2‐mutant induced pluripotent stem cells (iPSCs) were derived from a patient with Parkinson's disease (PD). Using CRISPR/Cas9–mediated gene editing, the pathogenic LRRK2 mutations were precisely corrected, and isogenic dopaminergic neural progenitor cells (DA‐NPCs) were subsequently generated.

ANXA2+ Small Extracellular Vesicles Drive Chemoresistance in Anaplastic Thyroid Cancer by Promoting XRCC5 Lactylation and Enhancing Non‐Homologous End‐Joining Repair

Advanced Science, EarlyView.
ANXA2+ sEVs promote cisplatin resistance in ATC by stabilizing the SRC/LDHA interaction, increasing LDHA phosphorylation and activity, and lactate production. Elevated lactate levels promote KAT5‐mediated lactylation of XRCC5 at lysine 265, enhancing its binding to XRCC6.

Liver Endothelia Orchestrate MASH‐Associated Macrophage Zonation Through FSTL1‐ITGA4 Axis

Advanced Science, EarlyView.
Liver inflammation in MASH fundamentally hinges on the newly defined Kit/STAT2/FSTL1/ITGA4 axis. Declining endothelial Kit collapses normal hepatic zonation, driving an aberrant FSTL1 gradient that recruits pathogenic macrophages. Strikingly, targeting FSTL1‐ITGA4 with anti‐VLA4 restores spatial immune homeostasis and halts disease progression ...

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

CXCL10/SLC11A1 Axis Exacerbates Septic Liver Injury by Regulating Neutrophil Extracellular Traps Formation to Drive Macrophage Pro‑Inflammatory Polarization

Advanced Science, EarlyView.
In sepsis‐induced liver injury, marked neutrophil infiltration correlates with disease severity. Neutrophil SLC11A1 drives intracellular Fe2+ and ROS via the Fenton reaction, promoting NETs formation. Hepatocyte‐derived CXCL10 recruits neutrophils and activates the JAK/STAT1/SLC11A1 axis, enhancing NETs‐mediated inflammation.
