Assemblies of d-Peptides for Targeting Cell Nucleolus. [PDF]
Selectively targeting the cell nucleolus remains a challenge. Here, we report the first case in which d-peptides form membraneless molecular condensates with RNA for targeting cell nucleolus. A d-peptide derivative, enriched with lysine and hydrophobic residues, self-assembles to form nanoparticles, which enter cells through clathrin-dependent ...

The nucleolus: a paradigm for cell proliferation and aging [PDF]
The nucleolus is the cellular site of ribosome biosynthesis. At this site, active ribosomal DNA (rDNA) genes are rapidly transcribed by RNA polymerase I (pol I) molecules.

Nucleolus and Nucleolar Stress: From Cell Fate Decision to Disease Development
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.

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

Developmental regulation of nucleolus size during Drosophila eye differentiation. [PDF]
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 ...

Nucleoli are membrane-less structures located within the nucleus and are known to be involved in many cellular functions, including stress response and cell cycle regulation. Besides, many viruses can employ the nucleolus or nucleolar proteins to promote

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

Plant Cell Nucleolus as a Hot Spot for Iron [PDF]
Many central metabolic processes require iron as a cofactor and take place in specific subcellular compartments such as the mitochondrion or the chloroplast. Proper iron allocation in the different organelles is thus critical to maintain cell function and integrity.
