We carried out metagenomic shotgun sequencing and a metagenome-wide association study (MGWAS) of fecal, dental and salivary samples from a cohort of individuals with rheumatoid arthritis (RA) and healthy controls. Concordance was observed between the gut and oral microbiomes, suggesting overlap in the abundance and function of species at different body(More)
OBJECTIVE To evaluate the potential for diagnosing colorectal cancer (CRC) from faecal metagenomes. DESIGN We performed metagenome-wide association studies on faecal samples from 74 patients with CRC and 54 controls from China, and validated the results in 16 patients and 24 controls from Denmark. We further validated the biomarkers in two published(More)
Emerging evidence has linked the gut microbiome to human obesity. We performed a metagenome-wide association study and serum metabolomics profiling in a cohort of lean and obese, young, Chinese individuals. We identified obesity-associated gut microbial species linked to changes in circulating metabolites. The abundance of Bacteroides thetaiotaomicron, a(More)
In recent years, metagenome-wide association studies have revealed potential relationships between intestinal microbiomes and the pathogenesis of type 2 diabetes mellitus (T2DM). However, considering the increase in volume of gene catalogues and algorithms, an updated analysis would be expected to confirm previous discoveries and provide new knowledge. We(More)
