Abstract

Colorectal cancer (CRC) represents the third most common cancer worldwide. Consequently, there is an urgent need to identify novel preventive and therapeutic strategies for CRC. This study aimed to screen for beneficial bacteria that have a preventive effect on CRC and to elucidate the potential mechanisms. Initially, we compared gut bacteria and bacterial metabolites of healthy volunteers and CRC patients, which demonstrated that intestinal conjugated linoleic acid (CLA), butyric acid, and Bifidobacterium in CRC patients were significantly lower than those in healthy volunteers, and these indicators were significantly negatively correlated with CRC. Next, spontaneous CRC mouse model were conducted to explore the effect of supplemental CLA-producing Bifidobacterium on CRC. Supplementation of mice with CLA-producing Bifidobacterium breve CCFM683 and B. pseudocatenulatum MY40C significantly prevented CRC. Moreover, molecular approaches demonstrated that CLA and the CLA-producing gene, bbi, were the key metabolites and genes for CCFM683 to prevent CRC. Inhibitor intervention results showed that PPAR-γ was the key receptor for preventing CRC. CCFM683 inhibited the NF-κB signaling pathway, up-regulated MUC2, Claudin-1, and ZO-1, and promoted tumor cell apoptosis via the CLA-PPAR-γ axis. Additionally, fecal microbiota transplantation (FMT) and metagenomic analysis showed that CCFM683 up-regulated Odoribacter splanchnicus through CLA production, which then prevented CRC by producing butyric acid, up-regulating TJ proteins, regulating cytokines, and regulating gut microbiota. These results will contribute to the clinical trials of Bifidobacterium and the theoretical research and development of CRC dietary products.

  • The Odoribacter genus is strongly associated with bile acids and short-chain fatty acids.

    “This certain bacterial genus was strongly associated with the bile acids (BAs) and short-chain fatty acids (SCFAs) (Chen et al. 2025; Sato et al. 2021).”

    From Odoribacter laneus protects intestinal barrier by bile acid-FXR axis in acute pancreatitis (2026) · cites this paper as Chen et al. 2025

    The Results section (Effects of O. splanchnicus on CRC mice; page unavailable) reports that O. splanchnicus treatment significantly increased butyric acid, a short-chain fatty acid, but did not increase the other short-chain fatty acids measured. Our copy does not report an association between Odoribacter and bile acids, so it does not support the full claim. (LLM, conf=0.87)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
