Similar results were obtained by KEGG analysis, which showed that genes were mainly involved in metabolic pathways, including tryptophan metabolism, sulfur metabolism, steroid hormone biosynthesis, oxidative phosphorylation, non-alcoholic fatty liver disease, the insulin signaling pathway, fatty acid degradation, and butanoate metabolism (Figure 2E). The gene discussed is INS; the disease is metabolic dysfunction-associated steatotic liver disease.
