1 Acetate, a precursor of acetyl-CoA (a product of fatty acid beta-oxidation [FAO]), or dichloroacetate, a compound that promotes pyruvate oxidation and generation of mitochondrial acetyl-CoA, were used for metabolic intervention RESULTS: Crypt cells rapidly absorbed labeled fatty acid, and mRNA levels of Lgr5+ stem cell markers (Lgr5, Olfm4, Smoc2, Msi1, and Ascl2) were downregulated in organoids incubated with etomoxir, an inhibitor of FAO, indicating that FAO was required for renewal of ISCs.
