Gut microbiome showing changes in “AOM/DSS and TP addition” and “sex and ORX” criteria. (A–C) The abundance ratio of butyrate-producing bacteria among commensal bacteria. (A) Clostridium indolis (Firmicutes: Clostridia: Clostridiales: Lachnospiraceae: Clostridium_g34). (B) Flintibacter butyricus (Firmicutes: Clostridia: Clostridiales: Ruminococcaceae: Pseudoflavonifractor). (C) Kineothrix alysoides (Firmicutes: Clostridia: Clostridiales: Lachnospiraceae: Kineothrix). (D–F) The abundance ratio of commensal bacteria. (D) Parabacteroides goldsteinii (Bacteroidetes: Bacteroidia: Bacteroidales: Porphyromonadaceae: Parabacteroides). (E) Romboutsia timonensis (Firmicutes: Clostridia: Clostridiales: Peptostreptococcaceae: Romboutsia). (F) Ruminococcus bromii (Firmicutes: Clostridia: Clostridiales: Ruminococcaceae: Ruminococcus_g2). (G–J) The abundance ratio of opportunistic pathogens. (G) Bacteroides caccae (Bacteroidetes: Bacteroidia: Bacteroidales: Bacteroidaceae: Bacteroides). (H) Mucispirillum schaedleri (Deferribacteres: Deferribacteres_c: Deferribacterales: Deferribacteraceae: Mucispirillum). (I) Akkermansia muciniphila (Verrucomicrobia: Verrucomicrobiae: Verrucomicrobiales: Akkermansiaceae: Akkermansia). (J) Bacteroides vulgatus (Bacteroidetes: Bacteroidia: Bacteroidales: Bacteroidaceae: Bacteroides). AOM, azoxymethane; CON, control; DSS, dextran sulfate sodium salt; ORX, orchiectomized; SEM, standard error of the mean; TP, testosterone propionate. Data are expressed as the mean±SEM. Whiskers show the minimum and maximum values. The p-values were calculated from the Mann-Whitney U test for comparison difference between independent two groups. *p < 0.05 for “CON vs. AOM/DSS” or “AOM/DSS vs. AOM/DSS+TP” in female, male, and ORX groups, †p < 0.05 for “Female vs. Male”, ‡p < 0.05 for “Male vs. ORX”, §p < 0.05 for “Female vs. ORX” in CON, AOM/DSS, and AOM/DSS+TP subgroups.
