Abstract

Microbiome-mediated suppression of carcinogenesis may open new avenues for identification of therapeutic targets and prevention strategies in oncology. Histidine decarboxylase (HDC) deficiency has been shown to promote inflammation-associated colorectal cancer by accumulation of CD11b+Gr-1+ immature myeloid cells, indicating a potential antitumorigenic effect of histamine. Here, we demonstrate that administration of hdc+Lactobacillus reuteri in the gut resulted in luminal hdc gene expression and histamine production in the intestines of Hdc-/- mice. This histamine-producing probiotic decreased the number and size of colon tumors and colonic uptake of [18 F]-fluorodeoxyglucose by positron emission tomography in Hdc-/- mice. Administration of L. reuteri suppressed keratinocyte chemoattractant (KC), Il22, Il6, Tnf, and IL1α gene expression in the colonic mucosa and reduced the amounts of proinflammatory, cancer-associated cytokines, keratinocyte chemoattractant, IL-22, and IL-6, in plasma. Histamine-generating L. reuteri also decreased the relative numbers of splenic CD11b+Gr-1+ immature myeloid cells. Furthermore, an isogenic HDC-deficient L. reuteri mutant that was unable to generate histamine did not suppress carcinogenesis, indicating a significant role of the cometabolite, histamine, in suppression of chronic intestinal inflammation and colorectal tumorigenesis. These findings link luminal conversion of amino acids to biogenic amines by gut microbes and probiotic-mediated suppression of colorectal neoplasia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Gut l-histidine levels may be decreased in older adults, which could lead to an altered immune state.

    “In total, these results indicate that gut l-histidine levels may be decreased in older adults, which could lead to an altered immune state, as l-histidine metabolites have been demonstrated to influence colonic inflammation (Gao et al., 2017).”

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.
