Summary
Long non-coding RNAs (lncRNAs) are crucial components of the genome’s ‘dark matter,’ playing vital roles in cellular functions and disease development. Understanding lncRNA function is key to developing new diagnostics and therapies for various human diseases.
Area of Science:
- Genomics and molecular biology
- Non-coding RNA research
- Disease mechanisms
Background:
- Genomes contain vast non-coding regions ('dark matter') with limited understanding.
- Protein-coding genes represent less than 5% of the human genome.
- Long non-coding RNAs (lncRNAs) are a key component of this non-coding fraction.
Purpose of the Study:
- To elucidate the molecular and cellular functions of lncRNAs.
- To understand how lncRNA misregulation contributes to human disease.
- To explore the potential of lncRNAs as biomarkers and therapeutic targets.
Main Methods:
- Review of current research themes in lncRNA biology.
- Analysis of lncRNA roles in the nucleus and cytoplasm.
- Examination of evolutionary conservation as a measure of lncRNA importance.
Main Results:
- lncRNAs exhibit diverse roles in cellular processes.
- Misregulation of lncRNAs is implicated in various diseases.
- Evolutionary conservation aids in identifying functional lncRNAs.
Conclusions:
- lncRNAs are critical regulators with significant implications for human health.
- Further research into lncRNA function is vital for advancing disease understanding and treatment.
- lncRNAs hold promise as biomarkers and therapeutic agents.

9.6K
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...

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.

01:20Types of RNA
8.6K
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 regulating 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.

01:53RNA Stability
35.5K
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...
