Soluble MAdCAM-1 as a biomarker in metastatic renal cell carcinoma
Patients with metastatic renal cell carcinoma treated with immune checkpoint inhibitors or antiangiogenic tyrosine kinase inhibitors may develop resistance driven by gut dysbiosis, which disrupts the MAdCAM-1–α4β7 axis and promotes the recruitment of immunosuppressive IL-17-producing T regulatory (Tr17) cells into tumors.
Notably, low sMAdCAM-1 levels were associated with an immunosuppressive gut microbiota profile dominated by Enterocloster species. Therefore, sMAdCAM-1 deserves further investigations as a biomarker-guided tool for microbiota-targeted interventions.

ArticleIntegrative analyses of dicarbonyls and advanced glycation end-products with multiomic profiles across tissue, plasma and stool samples reveal methylglyoxal accumulation in colon cancer
This pilot integrative analysis highlighted novel coherent associations among tissue, circulating, and stool levels of MGO-derived AGEs, the expression of AGE-related metabolic pathways, and microbial signatures in colon cancer. If confirmed in larger studies, these candidate molecular and microbial interactions may provide novel insights into the dicarbonyl stress involvement in tumor biology.

ArticleFrom Womb to Weaning: Microbial Signals That Shape the Developing Brain
This review synthesizes current knowledge on the temporal dynamics of gut colonization and brain maturation. Drawing on mechanistic insights from animal models, we emphasize the central role of the maternal microbiota and particularly, microbially derived metabolites that cross the feto-placental barrier and shape fetal brain development. We also discuss molecular and cellular targets of microbial influence, implications for neurodevelopmental disorders, and potential therapeutic strategies.

ArticleFaecalibacterium prausnitzii, depleted in the Parkinson’s disease microbiome, improves motor deficits in α-synuclein overexpressing mice
Gut microbiome composition is altered in Parkinson’s disease (PD), the fastest-growing neurological condition, that is characterized by neurodegeneration, motor dysfunction, and is frequently accompanied by gastrointestinal (GI) symptoms.
