Summary
Natural antisense transcripts in mammals are diverse and functional, not just regulatory RNAs. These molecules employ various mechanisms to play significant biological roles.
Area of Science:
- Genomics
- Molecular Biology
- RNA Biology
Background:
- Mammalian genomes contain many natural antisense transcripts (NATs).
- The precise functions of NATs remain largely uncharacterized.
- Previous assumptions viewed NATs as a uniform class of regulatory RNAs.
Purpose of the Study:
- To investigate the functional diversity of natural antisense transcripts.
- To explore the mechanisms by which NATs regulate gene expression.
- To categorize NATs based on their biological roles and regulatory strategies.
Main Methods:
- Functional validation studies of NATs.
- Analysis of transcriptional regulatory mechanisms.
- Investigation of post-transcriptional gene regulation by NATs.
Main Results:
- Antisense transcripts are not a homogenous group.
- NATs exhibit diverse functional categories.
- Evidence supports frequent functionality of NATs.
- NATs utilize varied transcriptional and post-transcriptional mechanisms.
Conclusions:
- Natural antisense transcripts are functionally versatile.
- NATs play critical roles in diverse biological processes.
- Understanding NATs requires acknowledging their multifaceted nature and regulatory strategies.

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)...

01:20Types of RNA
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.

01:23RNA Interference
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
