Résumé

Embedded into a complex signaling network coordinating glucose uptake, usage and production, the nuclear bile acid receptor FXR is expressed in several glucose-processing organs including the liver which synthesizes, stores or mobilizes glucose according to the organism's needs. Dysregulated in type 2 diabetes, hepatic gluconeogenesis (GNG) is controlled through allosteric regulation of gluconeogenic enzymes and by glucagon/cAMP-dependent transcriptional regulatory pathways. Whether FXR positively or negatively regulates fasting hepatic gluconeogenesis is still debated.
