Multi-omic analysis reveals transkingdom gut dysbiosis in metabolic dysfunction-associated steatotic liver disease.

ABSTRACT: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common condition linked to obesity and the metabolic syndrome, yet its transkingdom connections have been under-investigated. We performed high-resolution multi-omic profiling-including stool metagenomes, metatranscriptomes and metabolomes-in 211 MASLD cases and 502 controls from a cohort of female nurses. Here we show that MASLD is associated with shifts in 66 gut bacterial species, including widespread enrichment of oral-typical microbes, and transkingdom dysbiosis involving not only bacterial but also viral taxa. Streptococcus spp. are more abundant in non-lean versus lean MASLD, the latter being a paradoxical subtype of a disease typically associated with increased adiposity. These microbial changes correspond with s
