ABCG2 and hepatitis C virus infection: Within the main KEGG categories, LEfSe analysis indicated that homologous recombination; galactose metabolism; other glycan degradation; starch and sucrose metabolism; amino sugar and nucleotide sugar metabolism; biosynthesis of antibiotics; biosynthesis of amino acids; biosynthesis of secondary metabolites; and metabolic pathways were enriched in 6-OHDA-lesioned group, whereas ribosome; carbon metabolism; quorum sensing; tryptophan metabolism; alanine, aspartate and glutamate metabolism; hepatitis C; ABC transporters metabolism pathway genes were enriched in sham-operated group (Fig 6).
