Postmaturity in the rat: phosphorylase, glucose-6-phosphatase and phosphoenolpyruvate carboxykinase activities in the fetal liver. 1978

B Portha, and E Le Provost, and L Picon, and G Rosselin

Liver glucose-6-phosphatase and phosphoenolpyruvate carboxykinase activities were increased in the postmature rat fetus (23.5 day old) when compared to term rat fetus (21.5 day old). Postmaturity was without effect on liver phosphorylase activity. The three liver enzyme activities were also determined in normal 2 day old neonates. These results are correlated with the mobilisation of fetal liver glycogen occuring during postmaturity in the rat and are discussed in relation to the secretory pattern of the pancreatic hormones.

D010729	Phosphoenolpyruvate Carboxykinase (GTP)	An enzyme of the lyase class that catalyzes the conversion of GTP and oxaloacetate to GDP, phosphoenolpyruvate, and carbon dioxide. This reaction is part of gluconeogenesis in the liver. The enzyme occurs in both the mitochondria and cytosol of mammalian liver. (From Dorland, 27th ed) EC 4.1.1.32.

D005333	Fetus	The unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
