Summary
Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), regulate gene expression and are linked to diseases. Modulating ncRNA activity offers a promising therapeutic strategy for various conditions.
Area of Science:
- Molecular Biology
- Genetics
- Epigenetics
Background:
- Non-coding RNAs (ncRNAs) play crucial roles in cellular processes, notably gene expression regulation.
- Two key classes, microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), function at post-transcriptional and epigenetic levels, respectively.
- Dysregulation of ncRNAs is associated with numerous human diseases, highlighting their therapeutic potential.
Purpose of the Study:
- To review the roles of miRNAs and lncRNAs in gene regulation.
- To explore therapeutic strategies for modulating ncRNA activity in disease.
- To discuss the potential of targeting ncRNAs for epigenetic-based therapies.
Main Methods:
- Antisense oligonucleotides and miRNA sponges to inhibit miRNA activity.
- miRNA mimics to restore deficient miRNA expression.
- Antisense technologies and small interfering RNAs (siRNAs) to modulate lncRNA function.
- Targeting promoter-associated RNAs and natural antisense transcripts for gene silencing or activation.
Main Results:
- Pharmacological modulation of ncRNAs presents a viable therapeutic avenue.
- Inhibition of miRNAs can be achieved via sequestration or degradation.
- Restoration of miRNA levels can be accomplished using miRNA mimics.
- lncRNAs can be silenced using antisense technologies or siRNAs.
- Targeting specific ncRNAs can induce transcriptional gene silencing or activation.
Conclusions:
- Modulating ncRNA activity, including miRNAs and lncRNAs, offers promising therapeutic strategies for various diseases.
- Targeting gene expression at the epigenetic level through ncRNA manipulation opens new avenues for treating human diseases.
- The development of ncRNA-based therapeutics holds significant potential for clinical applications.

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
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...

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...
