Identification of Nucleolus-Associated Chromatin Domains Reveals a Role for the Nucleolus in 3D Organization of the A. thaliana Genome

open access: yesCell Reports, 2016
The nucleolus is the site of rRNA gene transcription, rRNA processing, and ribosome biogenesis. However, the nucleolus also plays additional roles in the cell. We isolated nucleoli using fluorescence-activated cell sorting (FACS) and identified nucleolus-

The Cell’s Nucleolus: an Emerging Target for Chemotherapeutic Intervention [PDF]

open access: yesChemMedChem, 2013
AbstractThe transient nucleolus plays a central role in the up‐regulated synthesis of ribosomal RNA (rRNA) to sustain ribosome biogenesis, a hallmark of aberrant cell growth. This function, in conjunction with its unique pathohistological features in malignant cells and its ability to mediate apoptosis, renders this sub‐nuclear structure a potential ...

Nucleolar asymmetry and the importance of septin integrity upon cell cycle arrest. [PDF]

open access: yesPLoS ONE, 2017
Cell cycle arrest can be imposed by inactivating the anaphase promoting complex (APC). In S. cerevisiae this arrest has been reported to stabilize a metaphase-like intermediate in which the nuclear envelope spans the bud neck, while chromatin repeatedly ...

Regulation and Roles of the Nucleolus in Embryonic Stem Cells: From Ribosome Biogenesis to Genome Organization [PDF]

open access: yes, 2020
The nucleolus is the largest compartment of the eukaryotic cell's nucleus. It acts as a ribosome factory, thereby sustaining the translation machinery. The nucleolus is also the subnuclear compartment with the highest transcriptional activity in the cell,

The Multiple Functions of the Nucleolus in Plant Development, Disease and Stress Responses

open access: yesFrontiers in Plant Science, 2018
The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.

Nucleolar localization of the ErbB3 receptor as a new target in glioblastoma

open access: yesBMC Molecular and Cell Biology, 2022
Background The nucleolus is a subnuclear, non-membrane bound domain that is the hub of ribosome biogenesis and a critical regulator of cell homeostasis. Rapid growth and division of cells in tumors are correlated with intensive nucleolar metabolism as a ...

The nucleolus, an ally, and an enemy of cancer cells [PDF]

open access: yesHistochemistry and Cell Biology, 2018
The rates of ribosome production by a nucleolus and of protein biosynthesis by ribosomes are tightly correlated with the rate of cell growth and proliferation. All these processes must be matched and appropriately regulated to provide optimal cell functioning. Deregulation of certain factors, including oncogenes, controlling these processes, especially

Cic1p/Nsa3p is required for synthesis and nuclear export of 60S ribosomal subunits [PDF]

open access: yes, 2003
Cic1p/Nsa3p was previously reported to be associated with the 26S proteasome and required for the degradation of specific substrates, but was also shown to be associated with early pre-60S particles and to be localized to the nucleolus.
