When two became three: Shaping the nucleolus with Treacle
Cell 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 ...

Nucleolus disassembly and distribution of segregated nucleolar material in prophase of root-tip meristematic cells in Triticum aestivum L. [PDF]
Archives of Biological Sciences, 2015 This paper presents details of the process of nucleolar disassembly, studied by conventional transmission electron microscopy (TEM) in wheat root cells. In early prophase, chromatin condensation and irregular nucleolar morphology are observed, with many ...

Brazilian Journal of Medical and Biological Research, 2004 Cajal bodies (CB) are ubiquitous nuclear structures involved in the biogenesis of small nuclear ribonucleoproteins and show narrow association with the nucleolus. To identify possible relationships between CB and the nucleolus, the localization of coilin,

Frontiers in Microbiology, 2018 In the fast-growing Escherichia coli cells, RNA polymerase (RNAP) molecules are concentrated and form foci at clusters of ribosomal RNA (rRNA) operons resembling eukaryotic nucleolus. The bacterial nucleolus-like organization, spatially compartmentalized

Developmental regulation of nucleolus size during Drosophila eye differentiation. [PDF]
PLoS ONE, 2013 When cell cycle withdrawal accompanies terminal differentiation, biosynthesis and cellular growth are likely to change also. In this study, nucleolus size was monitored during cell fate specification in the Drosophila eye imaginal disc using fibrillarin ...

Nucleolus and Nucleolar Stress: From Cell Fate Decision to Disease Development
Cells, 2022 Besides the canonical function in ribosome biogenesis, there have been significant recent advances towards the fascinating roles of the nucleolus in stress response, cell destiny decision and disease progression.

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

The nucleolus: a raft adrift in the nuclear sea or the keystone in nuclear structure?
Biomolecular Concepts, 2013 The nucleolus is a prominent nuclear structure that is the site of ribosomal RNA (rRNA) transcription, and hence ribosome biogenesis. Cellular demand for ribosomes, and hence rRNA, is tightly linked to cell growth and the rRNA makes up the majority of ...
