Profiling Carbohydrate Metabolism in Liver and Hepatocellular Carcinoma with [¹³C]-Glycerate Probes.

ABSTRACT: The interplay between glycolysis and gluconeogenesis is central to carbohydrate metabolism. Here, we describe novel methods to assess carbohydrate metabolism using [¹³C]-probes derived from glycerate, a molecule whose metabolic fate in mammals remains underexplored. Isotope-based studies were conducted via NMR and mass spectrometry analyses of freeze-clamped liver tissue extracts after [2,3-¹³C₂]glycerate infusion. The ex vivo investigations were correlated with in vivo measurements using hyperpolarized [1-¹³C]glycerate. Application of [¹³C]glycerate to N-nitrosodiethylamine (DEN)-treated rats provided further assessments of intermediary carbohydrate metabolism in hepatocellular carcinoma. This method afforded direct anal
