This is contradictory to the experimental results in this study, because we had a significant increase in Parasutterella in the CRC group when compared to that of the control group after the administration of AOM/DSS-induced colitis; Odoribacter in the CRC + Fn + Cys group also showed a significant increase when compared to the other three groups. The gene discussed is FN1; the disease is colorectal carcinoma.
