Is thiamine pyrophosphatase a reliable marker of the neuronal Golgi apparatus? A critical analysis. 1979

H Luppa, and H G Bernstein, and J Weiss

The thiamine pyrophosphatase histochemical technique is believed to be a suitable approach to the selective staining of the Golgi vesicles of all animal cells, icluding the neuron. However, during the past decade a considerable number of data have been published, suggesting that the TPPase is in general a membrane-associated enzyme in the brain, which can be found in subcellular fractions other than Golgi lamellae. It has therefore become necessary to reconsider the view that thiamine pyrophosphatase is an exclusive marker enzyme of the Golgi apparatus.

UI	MeSH Term	Description	Entries
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D011755	Pyrophosphatases	A group of enzymes within the class EC 3.6.1.- that catalyze the hydrolysis of diphosphate bonds, chiefly in nucleoside di- and triphosphates. They may liberate either a mono- or diphosphate. EC 3.6.1.-.	Pyrophosphatase
D006056	Golgi Apparatus	A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins, receiving them from the rough ENDOPLASMIC RETICULUM and directing them to secretory vesicles, LYSOSOMES, or the CELL MEMBRANE. The movement of proteins takes place by transfer vesicles that bud off from the rough endoplasmic reticulum or Golgi apparatus and fuse with the Golgi, lysosomes or cell membrane. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990)	Golgi Complex,Apparatus, Golgi,Complex, Golgi
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
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.	Animal,Metazoa,Animalia
D013834	Thiamine Pyrophosphatase	An enzyme that hydrolyzes thiamine pyrophosphate to thiamine monophosphate plus inorganic phosphate. EC 3.6.1.-.	TPPase,Thiamine Pyrophosphate Phosphohydrolase,Phosphohydrolase, Thiamine Pyrophosphate,Pyrophosphatase, Thiamine,Pyrophosphate Phosphohydrolase, Thiamine
