Figure 3 | Overview of gene expression profiles by gut microbiota. (A) Principal component analysis (PCA) of different treatment. N1 represents the first day (D1) of the non-toxic diet, N2 represents the second day (D2) of the non-toxic diet, T1 represents D1 of the toxic diet, T2 represents D2 of the toxic diet. (B) Differentially expressed gene (DEG) number; (C) Significantly enriched and upregulated metabolic pathways.
