Further studies on the mammalian cell nucleolus
Journal of Ultrastructure Research, 1976A new nucleolar fraction (P 0 ) that is observed following drug treatment (actinomycin D, proflavine, camptothecin, and adenosine) of tissue culture cells has been identified and its properties are described. In addition, other previously described structural entities that appear as a result of drug treatment have further been analyzed and discussed ...

The Nucleolus of the Apodan Sertoli Cell
Nature, 1948THE association of desoxyribose nucleic acid with the nucleolus has been reported in a number of different types of cells. Hyden1 in nerve cells, Davidson2 in the rat liver cell and Koller3 in tumour cells, find that particles or granules giving a positive Feulgen reaction occur on the periphery of the Feulgen-negative nucleolus.

The nucleolus: the magician's hat for cell cycle tricks
Current Opinion in Cell Biology, 2000The nucleolus, for decades considered a ribosome factory and site for ribosomal RNA synthesis and processing, has recently acquired new fame. Analyses of proteins important for cell-cycle regulation have shown that this organelle is used to sequester proteins, thereby inhibiting their activity.

Nucleolus‐associated J chains in myeloma cells
Scandinavian Journal of Haematology, 1986Bone marrow aspirates from 10 patients with multiple myeloma (6 IgG myeloma, 3 IgA myeloma, 1 Bence Jones myeloma) were examined for nucleolus‐associated localization of J chains. On light microscopy using the PAP method, almost all or a significant number of myeloma cells exhibited intranuclear spots stained with anti‐J chains in 3 (IgG myeloma) out ...

Proteomic profiling of the human T-cell nucleolus
Molecular Immunology, 2011The nucleolus, site of ribosome biogenesis, is a dynamic subnuclear organelle involved in diverse cellular functions. The size, number and organisation of nucleoli are cell-specific and while it remains to be established, the nucleolar protein composition would be expected to reflect lineage-specific transcriptional regulation of rDNA genes and have ...

Two Types of Ribonucleoprotein in the Nucleolus of Mammalian Cells
Nature, 1959NUCLEOLAR differentiation has been recognized since the time of Gustav Valentin. Agassiz1 referred to a body within the nucleolus of the turtle egg as the “Valentinian vesicle”. Montgomery2 and Heidenhain3 called this structure the nucleolinus. Recently, it has been suggested that the appearance of vesicular or solid nucleolini is due to the presence ...

Distribution of U3 snRNA in the nucleolus of CHO cells
Biology of the Cell, 1985Localization of snRNA at the ultrastructural level was studied in the nucleolus of CHO cells by EM autoradiography. In conditions where snRNA U3 is the only RNA species labelled in the nucleolus, silver grains were largely found at the periphery, over the granular ribonucleoprotein component and the perinucleolar condensed chromatin; this enrichment ...

Annular nucleolus in Leydig cells of mouse
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1973Many mature Leydig cells of adult mice contain annular nucleoli. In the cytoplasm of these cells, there is an abundance of agranular endoplasmic reticulum and its modifications, i.e. membranous whorls and double-walled tubules. By contrast, the cytoplasm of Leydig cells with compact nucleoli shows abundant free ribosomes and granular endoplasmic ...
