The role of the gut microbiome in the regulation of high‐altitude adaptation

open access: yesiMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

Oral proton‐reprogrammed nanomedicine to break the inflammatory bowel disease‐Clostridium difficile infection vicious cycle

open access: yesiMeta, EarlyView.
Research on the mechanism of OPR restoring intestinal epithelial cell (IEC) structure and function in inflammatory bowel disease (IBD) treatment. (A) Schematic diagram of OPR structure and the rate of GP release under different conditions. (B) Schematic diagram of OPR targeting IBD colonic lesions through charge interaction.

Inhibition of ferroptosis by microbiota‐derived lithocholic acid underlies the intestinal radioprotection of a host defensin‐derived oligopeptide

open access: yesiMeta, EarlyView.
AT9(C/G), an oligopeptide derived from human defensin 5, enriches Bifidobacterium pseudolongum and increases lithocholic acid (LCA) levels in the intestine. Reduced levels of LCA link to increased severity of ionizing radiation‐induced intestinal injury (IRIII) in both murine and clinical studies.

Microbial metabolites in tumor epigenetic regulation

open access: yesiMeta, EarlyView.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Chondroitin sulfate restores muscle mass via gut–muscle axis remodeling through sugar–bile acid metabolism reprogramming

open access: yesiMeta, EarlyView.
The graphical abstract illustrates the molecular mechanism by which chondroitin sulfate (DCS) alleviates glucocorticoid‐induced myopathy through the gut–muscle axis. DCS selectively enriches L. johnsonii Z‐RW, enhancing bshA‐encoded BSH activity to promote bile acid deconjugation and reduce the sugar–bile acid ratio, thereby re‐establishing intestinal ...
