Etiology-associated differences in the gut microbiome and metabolome in hepatocellular carcinoma: an exploratory study of alcohol-related and HBV-related cases
Hepatocellular carcinoma (HCC) arises in heterogeneous etiological contexts, but direct cross-omics comparisons between HCC subgroups defined by different etiologies remain limited. In this exploratory study, we combined fecal 16S rRNA gene sequencing and untargeted serum metabolomics with exploratory cross-omics analy...
