The effects of progesterone on some of the hepatic enzymes associated with lipogenesis and gluconeogenesis in rats is presented. Progesterone was given, 1.25 mg, twice daily, for 14 days followed by 2.5 mg twice daily for 7 days. Animals were killed after 21 days of treatment. Enzymes studied included phosphofructokinase (PFK) malic enzyme (ME), glucose-6-phosphate dehydrogenase (G-6-PD), citrate cleavage enzyme (CCE), glycerol-3-phosphatee dehydrogenase (g-3-PD), fatty acid synthetase (FAS), pyruvate carboxylase (PC), phosphenolpyruvate carboxykinase (PEPCK), fructose-1,6-diphosphatase (FDPase), and lactate dehydrogenase (LDH). PFK, ME, G-6-PD, and CCE were elevated significantly after progesterone administration, while FAS and G-3-PD were unchanged. These changes may represent insulin effects. Progesterone treatment also results in increased PEPCK. This enzyme is associated with control of gluconeogenesis. PEPCK is considered to be a key rat-limiting enzyme in the "dicarboxylic acid shuttle." This finding may indicate an increased capability for glycogen formation.
