Abstract

Stable isotope-based dynamic metabolic profiling is applied in this paper to elucidate the mechanism by which butyrate induces cell differentiation in HT29 cells. We utilized butyrate-sensitive (HT29) cells incubated with [1,2-13C2]glucose or [1,2-13C2]butyrate as single tracers to observe the changes in metabolic fluxes in these cells. In HT29 cells, increasing concentrations of butyrate inhibited glucose uptake, glucose oxidation, and nucleic acid ribose synthesis in a dose-dependent fashion. Glucose carbon utilization for de novo fatty acid synthesis and tricarboxylic acid cycle flux was replaced by butyrate. We also demonstrated that these changes are not present in butyrate-resistant pancreatic adenocarcinoma MIA cells. The results suggest that the mechanism by which colon carcinoma cells acquire a differentiated phenotype is through a replacement of glucose for butyrate as the main carbon source for macromolecule biosynthesis and energy production. This provides a better understanding of cell differentiation through metabolic adaptive changes in response to butyrate in HT29 cells, demonstrating that variations in metabolic pathway substrate flow are powerful regulators of tumor cell proliferation and differentiation.

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.
