Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma

Advanced Science, EarlyView.
This review explains how chronic liver injury progresses toward hepatocellular carcinoma through interconnected changes in gut microbes, metabolism, immunity, fibrosis, and diet. It highlights microbial metabolites, bile‐acid signaling, immune dysfunction, and nutritional or microbiome‐based interventions as opportunities to identify risk earlier ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

A Molecular Engineering Strategy to Fine‐Tune Phototoxicity of AIE Probes for Super‐Resolution Imaging of Mitochondrial Cristae Dynamics

Advanced Science, EarlyView.
Regulation of molecular packing, phototoxicity, and ROS output of AIE photosensitizers is achieved through carboxylation and alkyl‐chain‐length tuning. The probe designed via this strategy enables super‐resolution visualization of inner‐mitochondrial‐membrane cristae dynamics under controlled oxidative stress, and fluorescence‐lifetime imaging of ...

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

Advanced Science, EarlyView.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.

Biosynthesis of Sciadonic Acid Derived from Gymnosperms with Anti‐Colitis Activity

Advanced Science, EarlyView.
This study establishes an efficient Yarrowia lipolytica platform for unusual sciadonic acid (SCA) production and assess the anti‐colitis efficacy in mice of SCA, supporting its potential as a novel therapeutic lipid. ABSTRACT Sciadonic acid (SCA), Δ5‐unsaturated fatty acid with anti‐inflammatory and lipid‐regulatory properties, is predominantly derived
