(A and B) Functional gene analysis in the DUOD: KEGG pathway analyses differentiate between healthy controls and patients with cirrhosis (A), as well as between compensated and decompensated stages of cirrhosis (B). (C and D) Gene expression profiles in cirrhosis: Hierarchical clustering heatmaps display changes in inflammation-related (C) and OXPHOS-related gene expression (D) in the DUOD and ASCEND colon of patients across different stages of cirrhosis compared with healthy controls, utilizing NanoString nCounter metabolic, inflammation, and fibrosis mRNA panels. (E and F) KEGG pathway analysis of DEGs in post-FMT DUOD versus pre-FMT (baseline). (E) DEGs suppressed after FMT. (F) DEGs activated after FMT.
