Summary
Regulatory non-coding RNAs (ncRNAs) are crucial for ribosomal RNA (rRNA) biogenesis in mammalian nucleoli. These ncRNAs control rRNA synthesis, processing, and modification, impacting cell viability and disease.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- Ribosomal RNA (rRNA) biogenesis occurs in the nucleolus, a key nuclear condensate.
- Accurate rRNA synthesis and processing are vital for ribosome function and protein translation.
- Nucleolar integrity reflects efficient rRNA production, essential for cell viability.
Purpose of the Study:
- To investigate RNA-mediated mechanisms controlling mammalian rRNA biogenesis.
- To highlight the role of regulatory non-coding RNAs (ncRNAs) in rRNA synthesis, processing, and modification.
- To explore the significance of ncRNAs in nucleolar morphology and their implications in human diseases.
Main Methods:
- Review of literature on RNA-mediated regulation of rRNA biogenesis.
- Focus on mammalian systems.
- Analysis of the role of ncRNAs in nucleolar function and disease.
Main Results:
- Regulatory ncRNAs are essential for controlling rRNA synthesis, processing, and modification.
- ncRNAs play a significant role in maintaining nucleolar morphology and function.
- Dysregulation of ncRNAs in rRNA biogenesis is linked to human diseases.
Conclusions:
- RNA-mediated mechanisms, particularly involving ncRNAs, are critical for precise rRNA biogenesis in mammals.
- ncRNAs are key regulators of nucleolar integrity and function.
- ncRNAs represent potential novel therapeutic targets for diseases associated with rRNA biogenesis defects.

Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

1.2K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

02:24Regulation of Expression Occurs at Multiple Steps
24.7K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
