Fig. 4From: Gut microbiota-derived tryptophan metabolites alleviate liver injury via AhR/Nrf2 activation in pyrrolizidine alkaloids-induced sinusoidal obstruction syndromeFeatures of gut microbiota in MCT-induced HSOS rats. A The alpha diversity (Chao1 index). B The PCoA plot analysis with unweighted UniFrac distance. C The bacterial composition at the genus level. D Changes of the specific genera in MCT-induced HSOS rats, especially the tryptophan-metabolizing bacteria. E The predicted bacterial functional genome based on KEGG database. Data were shown as mean ± SEM. N = 6–7. *p < 0.05, **p < 0.01.
