Antisense Oligonucleotides – The Revolutionizing Modalities in the Field of Gene Silencing

Oligonucleotide (commonly referred to as oligos), are brief single stranded DNA or RNA molecules, usually containing 15-20 nucleotide residues. In the modern-day biopharmaceuticals and biotechnology, the applications of these particles are large, consisting of (however not restricted to) hereditary testing, basic biomolecular research, and forensic analysis. Oligonucleotides are a varied class of therapies that are divided into many different classes, such as antisense, aptamers, miRNA, shRNA, siRNA and other types of oligonucleotides.

Oligonucleotide Therapeutics

RNAi is a natural process of post-transcriptional gene silencing, involving brief strands of nucleic acids. Cells utilize this process to silence and/ or prevent gene expression, through the targeted deterioration of specific (undesirable) mRNA molecules.
Antisense oligonucleotides (also called ASOs) are short RNA/ DNA based structures whose series specifically binds to the target RNA and inhibits the gene expression. [5] Antisense rehabs are considered to be one of the most promising agents for impairing the protein production and obstructing the function of the specific target gene of interest in the human genome. Currently, this mechanism forms the basis for lots of therapies being investigated in different stages of medical trials for treatment of a variety of cancers, viral diseases, and congenital diseases.

There are 2 principle techniques used for the advancement of RNA-based drugs; double stranded RNA-mediated disturbance (RNAi) and antisense oligonucleotides (ASO). Both approaches are presently in clinical trials for targeting of RNAs associated with various illness, such as cancer and neurodegeneration.

As suggested earlier, healing antisense oligonucleotides are normally made up of 18 to 30 base sets (bp). Examples of antisense therapeutics that have actually been approved by the FDA till date consist of nusinersen (treatment of numerous forms of back muscular atrophy (SMA)), eteplirsen (treatment of duchene muscular dystrophy (DMD)) and inotersen (treatment of familial amyloid polyneuropathy (FAP)).

The Evolving Landscape of Antisense Oligonucleotide Therapeutics

The marketplace is controlled by mid-sized and little firms based in North America and Europe. Among the particles developed by these gamers, 5 have been approved for different indications in regions, such as the US, Japan, Canada and the UK. Even more, almost 60% of the therapies in the pipeline are being evaluated by the players based in North America.

With the capability to interfere with the process of gene expression, antisense oligonucleotides are thought about to be one of the best options for gene control and problems of protein production. Offered the speed of innovation and advancements in this upcoming market, we can anticipate antisense oligonucleotides to become a significant healing modality in the anticipated future.

Further, bulk of the treatments (30) are created for administration through subcutaneous route. The subcutaneous path of administration assists in rapid beginning of healing action that can be extended to a longer period.
