A unique ball-shaped Golgi apparatus in the rat pituitary gonadotrope: its functional implications in relation to the arrangement of the microtubule network.
In polarized exocrine cells, the Golgi apparatus is cup-shaped and its convex and concave surfaces are designated as cis and trans faces, functionally confronting the rough endoplasmic reticulum and the cell surface, respectively. To clarify the morphological characteristics of the Golgi apparatus in non-polarized endocrine cells, the investigators immunocytochemically examined its precise arch...
متن کاملGolgi Apparatus of Rat Kidney
A procedure has been developed for the isolation of morphologically recognizable, largely intact, Golgi apparatus from rat kidneys. The fraction contains both uridine diphosphogalactose: IVacetylglucosamine galactosyltransferase and 3’-phosphoadenosine 5’-phosphosulfate: cerebroside sulfotransferase activities enriched 50to 80-fold over the original homogenate. Comparison of the Golgi-rich frac...

متن کاملMembrane fusion and glycosylation in the rat hepatic Golgi apparatus
When purified Golgi fractions were incubated with UDP-[3H]galactose in the absence of Triton-X-100, radioactivity was incorporated into an endogenous lipid and several peptide acceptors. Electron microscope analysis of Golgi fractions incubated in the endogenous galactosyl transferase assay medium revealed extensive fusion of Golgi saccules. Systematic removal of constituents in the galactosyl ...
متن کاملAssociation of kinesin with the Golgi apparatus in rat hepatocytes.
The Golgi apparatus is a dynamic membranous structure, which has been observed to alter its location and morphology during the cell cycle and after microtubule disruption. These dynamics are believed to be supported by a close structural interaction of the Golgi with the microtubule cytoskeleton and associated motor enzymes. One microtubule-dependent motor enzyme, kinesin, has been implicated i...
