A developmental study of neuron-specific enolase in rat adrenal medulla. 1982

S A Vinores, and P J Marangos

The levels of neuron-specific enolase (NSE) in rat adrenal medulla increase with age. A sharp increase was observed until the age of 15 days. At this time, the NSE level dropped slightly, followed by a gradual increase until the rats were 1 year old. The adrenal medullary NSE levels in males were higher than those observed in females. The difference was seen from 32 days of age, but was not statistically significant until 1 year. This study indicates that NSE can be used as a marker for differentiation in adrenal medulla, as it is used in the central nervous system and in neuroblastoma and pheochromocytoma cells.

D000313 Adrenal Medulla The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM. Adrenal Medullas,Medulla, Adrenal,Medullas, Adrenal
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.

D048948 14-3-3 Proteins A large family of signal-transducing adaptor proteins present in wide variety of eukaryotes. They are PHOSPHOSERINE and PHOSPHOTHREONINE binding proteins involved in important cellular processes including SIGNAL TRANSDUCTION; CELL CYCLE control; APOPTOSIS; and cellular stress responses. 14-3-3 proteins function by interacting with other signal-transducing proteins and effecting changes in their enzymatic activity and subcellular localization. The name 14-3-3 derives from numerical designations used in the original fractionation patterns of the proteins. 14-3-3 Protein,14-3-3 Protein, beta Isoform,14-3-3 Protein, epsilon Isoform,14-3-3 Protein, eta Isoform,14-3-3 Protein, gamma Isoform,14-3-3 Protein, tau Isoform,14-3-3 Protein, zeta Isoform,14-3-3 beta Protein,14-3-3 epsilon Protein,14-3-3 eta Protein,14-3-3 gamma Protein,14-3-3 tau Protein,14-3-3 zeta Protein,14-3-3beta Protein,14-3-3epsilon Protein,14-3-3eta Protein,14-3-3gamma Protein,14-3-3tau Protein,14-3-3zeta Protein,Brain 14-3-3 Protein,Protein 14-3-3,14 3 3 Protein,14 3 3 Protein, beta Isoform,14 3 3 Protein, epsilon Isoform,14 3 3 Protein, eta Isoform,14 3 3 Protein, gamma Isoform,14 3 3 Protein, tau Isoform,14 3 3 Protein, zeta Isoform,14 3 3 Proteins,14 3 3 beta Protein,14 3 3 epsilon Protein,14 3 3 eta Protein,14 3 3 gamma Protein,14 3 3 tau Protein,14 3 3 zeta Protein,14 3 3beta Protein,14 3 3epsilon Protein,14 3 3eta Protein,14 3 3gamma Protein,14 3 3tau Protein,14 3 3zeta Protein,14-3-3 Protein, Brain,Brain 14 3 3 Protein,Protein, 14-3-3tau,eta Protein, 14-3-3
