ChREBP Mediates Metabolic Remodeling in FBP1-deficient Liver.

The deficiency of fructose-1,6-bisphosphatase 1 (FBP1), a key enzyme of gluconeogenesis, causes fatty liver. However, its underlying mechanism and physiological significance are not fully understood. Here we demonstrate that carbohydrate response element-binding protein (ChREBP) mediates lipid metabolic remodeling and promotes progressive triglycerides accumulation against metabolic injury in adult FBP1-deficient liver.
