Fig. 2: PCoA plot using the Bray-Curtis dissimilarity index illustrating differences in gut microbiota composition between groups over time.

Fecal samples were analyzed at 2 weeks (A) and 0 weeks (B) before irradiation, and at 1 week (C), 3 weeks (D), and 6 weeks (E) after irradiation; n = 6 mice/group at each time point, for a total of 210 samples.
