• The SIRT1 activators isonicotinamide (IsoNAM), resveratrol, fisetin, and butein repressed transcription of the gene for the cytosolic form of phosphoenolpyruvate carboxykinase (GTP) (PEPCK-C). An evolutionarily conserved binding site for hepatic nuclear factor (HNF) 4α (-272/ -252) was identified, which was required for transcriptional repression of the PEPCK-C gene promoter caused by these compounds.

  • Methods: To address this question, transgenic Non-Obese Diabetic (NOD) mice which express insulin in the liver were made using the Phosphoenolpyruvate Carboxykinase (PEPCK) promoter to drive the mouse insulin I gene (Ins). (deepdyve.com)
  • The results of RT-qPCR analysis and gain-of-function experiments confirmed the positive association between the IMF content and phosphoenolpyruvate carboxykinase 1 ( PCK1 ) expression in buffalo. (biomedcentral.com)
  • In glycolysis, PEP is formed by the action of the enzyme enolase on 2-phosphoglycerate. (hmdb.ca)
  • This reaction is catalyzed by the enzyme phosphoenolpyruvate carboxykinase (PEPCK). (hmdb.ca)
  • A cytosolic form of this protein is encoded by a different gene and is the key enzyme of gluconeogenesis in the liver. (nih.gov)
  • Absence of the enzyme leads to a fatal form of childhood hypertension termed, APPARENT MINERALOCORTICOID EXCESS SYNDROME. (lookformedical.com)
