D-gal injection influenced the microorganism structure of the gut microbiota in irradiated mice. (A–C) PCA analysis of the gut microbiota in mice from the ‘saline IR+’ and ‘D-gal IR+’ groups on Day 0 (A), Day 5 (B) and Day 10 (C) post-irradiation; n ≥ 10 mice per group. (D–F) PCoA analysis of the gut microbiota in mice from the ‘saline IR+’ and ‘D-gal IR+’ groups on Day 0 (D), Day 5 (E) and Day 10 (F) post-irradiation; n ≥ 10 mice per group. The difference in beta diversity was indicated by PERMANVO and is shown as the P value in the PCoA plot.
