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-

Mapping nucleolus-associated chromatin interactions using nucleolus Hi-C reveals pattern of heterochromatin interactions

open access: yesNature Communications, 2023
Here the authors developed a nucleolus Hi-C technique (nHi-C) for enriching nucleolus-associated interactions, and revealed specific heterochromatin interaction patterns within and around nucleoli in human cells at high resolution.

Genome Organization in and around the Nucleolus

open access: yesCells, 2019
The nucleolus is the largest substructure in the nucleus, where ribosome biogenesis takes place, and forms around the nucleolar organizer regions (NORs) that comprise ribosomal RNA (rRNA) genes.

Therapeutic Approaches Targeting Nucleolus in Cancer

open access: yesCells, 2019
The nucleolus is a distinct sub-cellular compartment structure in the nucleus. First observed more than 200 years ago, the nucleolus is detectable by microscopy in eukaryotic cells and visible during the interphase as a sub-nuclear structure immersed in ...

Space explorers need to be space farmers: What we know and what we need to know about plant growth in space

open access: yesMètode Science Studies Journal: Annual Review, 2021
Space exploration will require life support systems, in which plants can provide nutrients, oxygen, moisture, and psychological well-being and eliminate wastes. In alien environments, plants must adapt to a different gravity force, even the zero gravity

Recent transcriptomic studies to elucidate the plant adaptive response to spaceflight and to simulated space environments

open access: yesiScience, 2022
Summary: Discovering the adaptation mechanisms of plants to the space environment is essential for supporting human space exploration. Transcriptomic analyses allow the identification of adaptation response pathways by detecting changes in gene ...

The Nucleolus [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2010
When cells are observed by phase contrast microscopy, nucleoli are among the most conspicuous structures. The nucleolus was formally described between 1835 and 1839, but it was another century before it was discovered to be associated with a specific chromosomal locus, thus defining it as a cytogenetic entity. Nucleoli were first isolated in the 1950s,

Manipulation of Cellular Processes via Nucleolus Hijaking in the Course of Viral Infection in Mammals

open access: yesCells, 2021
Due to their exceptional simplicity of organization, viruses rely on the resources, molecular mechanisms, macromolecular complexes, regulatory pathways, and functional compartments of the host cell for an effective infection process.

The nucleolus [PDF]

open access: yesCurrent Opinion in Cell Biology, 1994
The transcriptionally active rRNA genes have the remarkable ability to organize and integrate the biochemical pathway of ribosome production into a structural framework, the nucleolus. The past year has seen numerous advances in our understanding of the relationships between nucleolar substructures, the site of ribosomal RNA (rRNA) gene transcription ...

Fibrillarin-GFP Facilitates the Identification of Meiotic Competent Oocytes

open access: yesFrontiers in Cell and Developmental Biology, 2021
The nucleolus undergoes significant functional changes and plays important roles during mammalian oocyte meiotic maturation. Fibrillarin (FBL) is the component of nucleolar small nuclear ribonucleoprotein (snRNP) particle and localizes to the dense ...
