Summary
Small nucleolar RNAs (snoRNAs), primarily known for rRNA processing, also regulate splicing, translation, and stress. These non-coding RNAs are implicated in diseases like cancer, revealing broader biological roles.
Area of Science:
- Molecular Biology
- Genetics
- Non-coding RNA Research
Background:
- Small nucleolar RNAs (snoRNAs) are abundant non-coding RNAs.
- Their primary known function involves ribosomal RNA (rRNA) processing.
- Emerging evidence suggests diverse roles beyond rRNA modification.
Purpose of the Study:
- To explore the expanding functional repertoire of snoRNAs.
- To highlight the involvement of snoRNAs in cellular processes beyond rRNA maturation.
- To underscore the significance of snoRNAs in disease pathogenesis.
Main Methods:
- Literature review of recent studies on snoRNA functions.
- Analysis of data linking snoRNAs to alternative splicing, translation, and oxidative stress.
- Examination of snoRNA roles in hereditary diseases and cancer.
Main Results:
- snoRNAs are confirmed to be involved in rRNA processing.
- New roles identified for snoRNAs in regulating alternative splicing and translation.
- snoRNAs implicated in cellular responses to oxidative stress.
- Association of snoRNAs with hereditary diseases and cancer pathogenesis established.
Conclusions:
- The functional scope of snoRNAs is considerably broader than previously understood.
- snoRNAs represent a versatile class of non-coding RNAs with critical roles in cellular regulation and disease.
- Further investigation into snoRNA functions is warranted to fully elucidate their biological significance.

02:53Ribosomal RNA Synthesis
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,...

02:55The Nucleolus
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

02:30siRNA - Small Interfering RNAs
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
