[Variations in acetylcholinesterase activity of the brain of Tenebrio molitor (Coleoptera) during metamorphosis and ecdysterone titer]. 1986

J J Lenoir-Rousseaux, and J Gautron

After the metamorphosis of Tenebrio molitor (Coleoptera), Acetylcholinesterase (AChE) activity per adult brain was twofold the activity of the last larval instar. During metamorphosis, from the prepupa to the adult fluctuations occurred in brain AChE activity per protein amount. These fluctuations were superimposable to the molting hormone (ecdysterone) variations in hemolymph so that each rise of ecdysterone was accompanied by an AChE peak.

D008675	Metamorphosis, Biological	Profound physical changes during maturation of living organisms from the immature forms to the adult forms, such as from TADPOLES to frogs; caterpillars to BUTTERFLIES.	Biological Metamorphosis,Biological Metamorphoses,Metamorphoses, Biological
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
D004441	Ecdysterone	A steroid hormone that regulates the processes of MOLTING or ecdysis in insects. Ecdysterone is the 20-hydroxylated ECDYSONE.	20-Hydroxyecdysone,Beta-Ecdysone,Crustecdysone,20 Hydroxyecdysone,Beta Ecdysone
D000110	Acetylcholinesterase	An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7.	Acetylcholine Hydrolase,Acetylthiocholinesterase,Hydrolase, Acetylcholine
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
