The effect of hormones on the transcription rate of cytosolic phosphoenolpyruvate carboxykinase and level of mRNA for this enzyme in the rat kidney has been investigated. In renal nuclei isolated from rats given dibutyryladenosine cyclic 3',5'-phosphate (Bt2cAMP) or 8-bromoadenosine cyclic 3',5'-phosphate (8-Br-cAMP), [32P]UMP incorporation into ...

As can be seen from the data presented in this chapter, glucagon, epinephrine and Bt2cAMP can act directly on isolated rat hepatocytes to markedly increase the concentration of P-enolpyruvate carboxykinase mRNA. The effects of these hormones on enzyme mRNa are rapid, causing a 2–3-fold increase in 90 min of incubation.

Phosphoenolpyruvate carboxykinase (PEPCK) is well known as a key enzyme involved in the metabolic pathway of gluconeogenesis in organisms, but the information about its involvement in immune response is still very limited. In the present study, a novel PEPCK homolog named CgPEPCK was identified from oyster Crassostrea gigas.

The first non-substrate like inhibitors of human cytosolic phosphoenolpyruvate carboxykinase (PEPCK) competitive with GTP are reported. An effort to discover orally active compounds that improve glucose homeostasis in Type 2 diabetics by reversibly inhibiting PEPCK led to the discovery of 1-allyl-3-butyl-8-methylxanthine (5).

Abstract In vitro , 3-mercaptopicolinic acid inhibited phosphoenolpyruvate carboxykinase activity in supernatant fractions of liver, kidney cortex, and adipose tissue obtained from fasted rats. 3-Mercaptopicolinic acid also inhibited enzymatic activity in the mitochondrial and supernatant fractions of liver obtained from fasted guinea pigs.

Using an in vitro assay with isolated rat nuclei, we have determined that thyroid hormone causes a 4-6-fold increase in the synthesis of mRNA coding for phosphoenolpyruvate carboxykinase. Proportional changes were seen in the steady-state cytosolic mRNA levels for phosphoenolpyruvate carboxykinase.

We report crystal structures of the human enzyme phosphoenolpyruvate carboxykinase (PEPCK) with and without bound substrates. These structures are the first to be determined for a GTP-dependent PEPCK, and provide the first view of a novel GTP-binding site unique to the GTP-dependent PEPCK family.

The structural gene Pck-1, encoding cytosolic phosphoenolpyruvate carboxykinase (GTP) (PEPCK; EC 4.1.1.32), has been assigned to mouse chromosome 2. This assignment was made based on genomic Southern transfer of rat-mouse and hamster-mouse hybrid DNAs using a rat kidney cloned cDNA of the PEPCK gene as a probe. Conclusive evidence for the cosegregation

The relationship between the control by cAMP of phosphoenolpyruvate carboxykinase (GTP) mRNA synthesis and breakdown was examined. The half-life of phosphoenolpyruvate carboxykinase mRNA was estimated from its decay rate in cells exposed to insulin (a specific inhibitor of phosphoenolpyruvate carboxy-kinase gene transcription) in the presence or ...
