Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

Microbial succinate promotes the response to metformin by upregulating secretory immunoglobulin a in intestinal immunity

Gut Microbes
Metformin is the first-line pharmacotherapy for type 2 diabetes mellitus; however, many patients respond poorly to this drug in clinical practice. The potential involvement of microbiota-mediated intestinal immunity and related signals in metformin ...

Reversing Macrophage Immunometabolic Dysfunction in Prolonged Infections Via a Glutaminolysis‐Fueled Restoration‐Based Hierarchically Selective Therapeutic System

Advanced Science, EarlyView.
A hierarchically selective immunotherapeutic nanoplatform, mGls@HEV‐MTP, selectively restores macrophage immunocompetence through GLS1‐mediated restoration of glutaminolysis‐fueled anaplerosis. Concurrently, it renders Staphylococcus aureus (S. aureus) more readily recognizable to the metabolically reprogrammed macrophages, thereby facilitating ...

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

Advanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

Targeting the KAT7/H3K14ac/RAC2 Axis Mediates OXPHOS to Promote Stemness Maintenance and Malignancy in Glioblastoma

Advanced Science, EarlyView.
SOX2 upregulates KAT7 in glioma stem cells, where KAT7 deposits H3K14 acetylation at the RAC2 promoter to activate RAC2 transcription. RAC2‐GTP subsequently promotes PAK1/2/3 phosphorylation, increasing tricarboxylic acid cycle flux and mitochondrial respiration to support glioblastoma malignancy.
