Summary
Long non-coding RNAs (lncRNAs) contain RNA G-quadruplexes (rG4s) that regulate cellular functions and disease. This review covers rG4 formation, protein interactions, detection methods, and therapeutic disruption strategies.
Area of Science:
- Molecular Biology
- Genomics
- RNA Biology
Background:
- Long non-coding RNAs (lncRNAs) are key regulators of cellular processes.
- Dysregulation of lncRNAs is associated with various diseases.
- RNA G-quadruplexes (rG4s) are structural motifs within lncRNAs with significant biological roles.
Purpose of the Study:
- To provide a comprehensive overview of rG4s in lncRNAs.
- To elucidate the formation, protein interactions, and cellular roles of rG4s.
- To discuss methodologies for studying rG4s and therapeutic strategies.
Main Methods:
- Literature review of rG4s in lncRNAs.
- Summary of experimental techniques for probing rG4s (small molecules, ligands, probes).
- Analysis of common rG4-interacting protein domains.
Main Results:
- rG4s play diverse roles in cellular function and disease pathogenesis.
- Various methods exist for detecting and analyzing rG4s.
- Specific protein domains interact with rG4s, offering therapeutic targets.
Conclusions:
- rG4s are critical structural elements in lncRNAs with implications for health and disease.
- Understanding rG4-protein interactions is crucial for developing targeted therapies.
- Further research into rG4s can unlock new therapeutic avenues for diseases linked to lncRNA dysregulation.

lncRNA - Long Non-coding RNAs
8.5K
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...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

RNA Structure
4.7K
The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

Nucleic Acid Structure
6.1K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.

RNA Stability
33.4K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
