Influence of D,L-ethionine intoxication on galactosyl transferase activity and morphology of the rat liver Golgi apparatus. 1984

A Kordowiak, and F Kaczmarski

Eight hours after single, intraperitoneal injection of D,L-ethionine to rats, statistically significant increased activity of liver Golgi apparatus UDP-Gal-GlcNAc transferase calculated per g as well as per total liver in comparison with control was found. Specific activity of the enzyme was higher than normal, however not statistically significant. Yield of Golgi-rich membrane fraction was unchanged in comparison with control. Slight stimulation of liver Golgi apparatus expressed in increased area of this organelle and marginal dilatation of dictyosome cisternae and secretory vacuoles were found in morphological analysis performed in electron microscope.

UI	MeSH Term	Description	Entries
D007788	Lactose Synthase	An enzyme complex that catalyzes the transfer of GALACTOSE from UDP GALACTOSE to GLUCOSE, forming LACTOSE. The enzyme complex is composed of a B subunit, ALPHA-LACTALBUMIN, which changes the substrate specificity of the A subunit, N-ACETYLLACTOSAMINE SYNTHASE, from N-ACETYLGLUCOSAMINE to glucose making lactose synthesis the preferred reaction.

D005001	Ethionine	2-Amino-4-(ethylthio)butyric acid. An antimetabolite and methionine antagonist that interferes with amino acid incorporation into proteins and with cellular ATP utilization. It also produces liver neoplasms.
D005260	Female		Females
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.

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.
