On the Locus of the Nucleolus [PDF]

open access: yes, 1994
In this paper we prove some properties of the locus of the nucleolus of a set C that can be the core of a cooperative game. We show that there are two subsets of C, the kernel and the least core, only dependent on the set C that contain this locus. From this fact we derive that for a set C which is the core of convex game the locus consists of one ...

Nucleolar Organization and Functions in Health and Disease

open access: yesCells, 2020
The nucleolus is a prominent, membraneless compartment found within the nucleus of eukaryotic cells. It forms around ribosomal RNA (rRNA) genes, where it coordinates the transcription, processing, and packaging of rRNA to produce ribosomal subunits ...

Distinct dynamics of the nucleolus in response to nutrient availability and during development in the rice blast fungus

open access: yesmBio, 2023
The nucleolus has emerged as a central hub for nuclear functions in eukaryotes. Studies in mammals and the model yeast Saccharomyces cerevisiae showed that the nucleolus is pivotal to nuclear functions other than ribosome biogenesis.

Nucleolar Proteome Analysis and Proteasomal Activity Assays Reveal a Link between Nucleolus and 26S Proteasome in A. thaliana

open access: yesFrontiers in Plant Science, 2017
In all eukaryotic cells, the nucleolus is functionally and structurally linked to rRNA synthesis and ribosome biogenesis. This compartment contains as well factors involved in other cellular activities, but the functional interconnection between non ...

Nucleolus and chromatin [PDF]

open access: yesHistochemistry and Cell Biology, 2018
The nucleolus as site of ribosome biogenesis holds a pivotal role in cell metabolism. It is composed of ribosomal DNA (rDNA), which is present as tandem arrays located in nucleolus organizer regions (NORs). In interphase cells, rDNA can be found inside and adjacent to nucleoli and the location is indicative for transcriptional activity of ribosomal ...

Nucleolar accumulation of RNA binding proteins induced by Actinomycin D is functional in Trypanosoma cruzi and Leishmania mexicana but not in T. brucei. [PDF]

open access: yesPLoS ONE, 2011
We have recently shown in T. cruzi that a group of RNA Binding Proteins (RBPs), involved in mRNA metabolism, are accumulated into the nucleolus in response to Actinomycin D (ActD) treatment. In this work, we have extended our analysis to other members of

rRNA transcription is integral to phase separation and maintenance of nucleolar structure.

open access: yesPLoS Genetics, 2023
Transcription of ribosomal RNA (rRNA) by RNA Polymerase (Pol) I in the nucleolus is necessary for ribosome biogenesis, which is intimately tied to cell growth and proliferation.

RepA Promotes the Nucleolar Exclusion of the V2 Protein of Mulberry Mosaic Dwarf-Associated Virus

open access: yesFrontiers in Microbiology, 2020
Plant viruses have limited coding capacities so that they rely heavily on the expression of multifunctional viral proteins to achieve a successful infection.

On the 1-nucleolus [PDF]

open access: yesMathematical Methods of Operations Research, 2017
This paper analyzes the 1-nucleolus and, in particular, its relation to the nucleolus. It is seen that, contrary to the nucleolus, the 1-nucleolus can be computed in polynomial time due to a characterization using a combination of standard bankruptcy rules for associated bankruptcy problems. Sufficient conditions on a compromise stable game are derived

Apoptosis and expression of argyrophilic nucleolus organizer regions in epithelial neoplasms of the larynx

open access: yesBrazilian Journal of Otorhinolaryngology, 2015
INTRODUCTION: Occurrence of apoptosis and expression of proliferative markers are powerful tools to establish a prognosis in the follow-up of cancer.OBJECTIVE: To evaluate the growth fraction in papillomas and laryngeal squamous cell carcinomas with ...
