Developmental changes of rat liver cytoplasmic and mitochondrial aconitate hydratases. 1978

A Masini, and V Guarriero-Bobyleva, and A Pincelli-Gatti, and C Cennamo

The developmental patterns of the activity of cytoplasmic and mitochondrial aconitate hydratses of rat liver have been studied. Both activities are low in foetal liver, with respect to adult levels, and begin to increase after birth. The activity of the mitochondrial enzyme reaches a maximum about two days after birth, then decreasing gradually to adult level. The activity of the cytoplasmic enzyme reaches its maximum level, nearly equal to adult level, about ten days after birth. The developmental pattern of the activity of the cytoplasmic aconitate hydratase may suggest a possible role of this enzyme in gluconeogenesis.

UI	MeSH Term	Description	Entries
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008930	Mitochondria, Liver	Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D000154	Aconitate Hydratase	An enzyme that catalyzes the reversible hydration of cis-aconitate to yield citrate or isocitrate. It is one of the citric acid cycle enzymes. EC 4.2.1.3.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
