The development of pyruvate dehydrogenase in the subhuman primate Macaca mulatta. 1977

B H Robinson, and W G Sherwood, and J Oei

The development of total pyruvate dehydrogenase activity in the subhuman primate, Macaca mulatta, was investigated in brain, liver, kidney cortex, and skeletal and cardiac muscle. Newborn primates delivered prematurely at 135 days of gestation had only 32% of this enzyme activity present in the brain compared to the full-term animal. Full-term animals were similar to adults. All tissues showed high activities of enzyme at 1 year of age compared either with neonates or adults. Kidney cortex showed an increase in activity from 807 +/- 74 mumol/g/min in prematurely delivered neonates to a maximum of 3,769 +/- 275 mumol/g/min in 1-year-old animals. The results are discussed in relation to the developing energy requirements of the tissues concerned.

D011768 Pyruvate Dehydrogenase Complex A multienzyme complex responsible for the formation of ACETYL COENZYME A from pyruvate. The enzyme components are PYRUVATE DEHYDROGENASE (LIPOAMIDE); dihydrolipoamide acetyltransferase; and LIPOAMIDE DEHYDROGENASE. Pyruvate dehydrogenase complex is subject to three types of control: inhibited by acetyl-CoA and NADH; influenced by the energy state of the cell; and inhibited when a specific serine residue in the pyruvate decarboxylase is phosphorylated by ATP. PYRUVATE DEHYDROGENASE (LIPOAMIDE)-PHOSPHATASE catalyzes reactivation of the complex.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
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.
