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 [1,2-13 C 2 ]glucose or [1,2-13 C 2 ]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 c… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
