Abstract

Fluoropyrimidines are the first-line treatment for colorectal cancer, but their efficacy is highly variable between patients. We queried whether gut microbes, a known source of inter-individual variability, impacted drug efficacy. Combining two tractable genetic models, the bacterium E. coli and the nematode C. elegans , we performed three-way high-throughput screens that unraveled the complexity underlying host-microbe-drug interactions. We report that microbes can bolster or suppress the effects of fluoropyrimidines through metabolic drug interconversion involving bacterial vitamin B 6 , B 9 , and ribonucleotide metabolism. Also, disturbances in bacterial deoxynucleotide pools amplify 5-FU-induced autophagy and cell death in host cells, an effect regulated by the nucleoside diphosphate kinase ndk-1 . Our data suggest a two-way bacterial mediation of fluoropyrimidine effects on host metabolism, which contributes to drug efficacy. These findings highlight the potential therapeutic power of manipulating intestinal microbiota to ensure host metabolic health and treat disease.

  • Some bacterial species enhanced one drug's effect while reducing another's.

    “Different bacterial species increased the response to 1 drug and decreased the effect of another.”
  • Bacterial ribonucleotide metabolism changed the cytotoxicity of 5-fluorouracil and 5-fluoro-20-deoxyuridine by shifting regulatory metabolites that synergized with drug-induced DNA damage.

    “Bacterial ribonucleotide metabolism affected the cytotoxic effects 5-fluorouracil and 5-fluoro-20-deoxyuridine by altering production of regulatory metabolites had synergistic effects with drug-induced DNA damage.”
  • In C. elegans, bacterial metabolism changes the effectiveness of 5-fluorouracil, 5-fluoro-20-deoxyuridine, and camptothecin.

    “Bacterial metabolism was found to affect the efficacy of the anti-pyrimidine drugs 5-fluorouracil and 5-fluoro-20-deoxyuridine and the topoisomerase I inhibitor camptothecin in Caenorhabditis elegans 191, 192.”
  • Bacterial uracil phosphoribosyltransferase can convert 5-FU to the RNA-damaging 5-fluorouridine monophosphate in a Caenorhabditis elegans model system.

    “the widely present bacterial uracil phosphoribosyltransferase (Martinussen and Hammer, 1994) can convert 5-FU to the RNA-damaging 5-fluorouridine monophosphate using the nematode Caenorhabditis elegans as a model system (Garcia-Gonzalez et al., 2017;Scott 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.
