Summary
MicroRNA (miRNA) therapeutics show great promise for treating diseases by regulating gene expression. However, despite extensive research, few miRNA-targeting drugs have reached clinical trials, indicating challenges in translating potential into practice.
Area of Science:
- Molecular Biology
- Genetics
- Biotechnology
Background:
- Therapeutic nucleic acids, including DNA and RNA oligonucleotides, have seen significant FDA approvals.
- RNA interference (RNAi) and antisense oligonucleotide therapies are rapidly expanding fields.
- MicroRNAs (miRNAs) are regulatory RNAs with altered expression in disease, presenting therapeutic potential.
Purpose of the Study:
- To evaluate the feasibility and practicality of miRNA-based therapeutics.
- To discuss the benefits and obstacles associated with targeting miRNAs for disease treatment.
- To explore the future prospects of miRNA therapeutics in clinical practice.
Main Methods:
- Review of existing literature on miRNA therapeutics.
- Analysis of clinical trial data for miRNA-targeting drugs.
- Discussion of scientific and practical challenges in miRNA drug development.
Main Results:
- A significant gap exists between the identification of miRNAs as therapeutic targets and their progression into clinical trials.
- While numerous studies highlight miRNA roles in various diseases, only a limited number of miRNA mimics or inhibitors have entered clinical development.
- The translation of miRNA research into approved therapies faces considerable hurdles.
Conclusions:
- The investment in identifying miRNA therapeutic targets has not yet yielded a commensurate number of clinically viable drugs.
- Overcoming obstacles related to delivery, stability, and specificity is crucial for advancing miRNA therapeutics.
- Further research and strategic development are needed to realize the full potential of miRNAs as a therapeutic modality.

siRNA - Small Interfering RNAs
18.2K
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...

RNA Interference
27.6K
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...

Experimental RNAi
7.2K
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...

MicroRNAs
3.6K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Types of 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.
