Cross-compartment signal propagation in the mitotic exit network

open access: yeseLife, 2021
In budding yeast, the mitotic exit network (MEN), a GTPase signaling cascade, integrates spatial and temporal cues to promote exit from mitosis. This signal integration requires transmission of a signal generated on the cytoplasmic face of spindle pole ...

The Unknown within the Known: Nucleolus, Understudied Compartment in the Filamentous Fungi

open access: yesMycobiology
Nucleolus is the most conspicuous sub-nuclear compartment that is well known as the site of RNA polymerase I-mediated rDNA transcription and assembly of ribosome subunits in eukaryotes.

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.

Cellular bases of the RNA metabolism dysfunction in motor neurons of a murine model of spinal muscular atrophy: Role of Cajal bodies and the nucleolus [PDF]

open access: yes, 2017
Spinal muscular atrophy (SMA) is caused by a homozygous deletion or mutation in the survival motor neuron 1 (SMN1) gene that leads to reduced levels of SMN protein resulting in degeneration of motor neurons (MNs).

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

open access: yesHepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

PQBP5/NOL10 maintains and anchors the nucleolus under physiological and osmotic stress conditions

open access: yesNature Communications, 2023
The nucleolus is a liquid-liquid phase separation droplet that dynamically changes under stress. Here, the authors report PQBP5/NOL10 is a critical component of the nucleolus, maintaining its structure and position in the nucleus during osmotic stress.

How to halve ploidy : lessons from budding yeast meiosis [PDF]

open access: yes, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

The nucleolus is the site for inflammatory RNA decay during infection

open access: yesNature Communications, 2022
The nucleolus is the traditional site for ribosomal RNA biogenesis. Here, the authors find that the nucleolus is a site of inflammatory pre-mRNA turnover and elucidated how immune homeostasis can be maintained by controlling inflammatory gene expression.

When two became three: Shaping the nucleolus with Treacle

open access: yesCell Reports, 2023
The nucleolus is a multiphase biomolecular condensate responsible for the initial steps of ribosome biogenesis. Jaberi-Lashkari et al.1 report that Treacle, a protein associated with a craniofacial distortion disease, played an evolutionary role in the ...

Computing the Least-core and Nucleolus for Threshold Cardinality Matching Games

open access: yes, 2014
Cooperative games provide a framework for fair and stable profit allocation in multi-agent systems. \emph{Core}, \emph{least-core} and \emph{nucleolus} are such solution concepts that characterize stability of cooperation.
