Five-country analysis of geographic and dietary drivers of gut microbiome composition and genomic variation

Abstract Human diet and lifestyle vary widely across cultures, shaping global diversity in gut microbiome composition and function. However, comparable cross-population studies have been limited by methodological heterogeneity. The Human Diets and Microbiome Initiative (THDMI) in...

Gut microbial and metabolic biomarkers for early-onset colorectal cancer

Early-onset colorectal cancer (EO-CRC) is a growing global health challenge with poorly understood etiology. While gut microbiota and metabolites are implicated in colorectal carcinogenesis, EO-CRC-associated signatures remain poorly characterized. This study presents the first l...
