Summary
RNA therapeutics offer a promising alternative to gene replacement, overcoming delivery challenges. These RNA-based strategies enable precise gene modulation, including splicing modification and allele-specific silencing.
Area of Science:
- Molecular Biology
- Biotechnology
- Genetics
Background:
- Conventional gene therapy faces significant hurdles in DNA delivery and in vivo regulation.
- Gene replacement strategies have shown limited clinical translation due to these challenges.
- RNA-based therapeutics present an alternative by utilizing short oligonucleotides and endogenous gene regulation.
Purpose of the Study:
- To review the potential of RNA therapeutics as an alternative to traditional gene therapy.
- To explore novel RNA-based strategies for genetic defect correction and gene expression modulation.
- To focus on specific RNA-based approaches including antisense oligonucleotides, pre-mRNA trans-splicing, and RNA interference.
Main Methods:
- Review of existing literature on RNA-based therapeutic strategies.
- Analysis of antisense oligonucleotide (ASO) modification of pre-mRNA splicing.
- Examination of pre-mRNA trans-splicing techniques and RNA interference (RNAi) for isoform- and allele-specific gene silencing.
Main Results:
- RNA therapeutics can circumvent DNA delivery and regulation issues inherent in gene therapy.
- Strategies like ASO modification allow for precise control over pre-mRNA splicing.
- RNA interference enables targeted silencing of specific gene transcripts, including disease-associated alleles or isoforms.
Conclusions:

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...
01:23RNA 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...

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:36What is Gene Expression?
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
