Summary
Antisense oligonucleotides can induce exon skipping to potentially treat Duchenne muscular dystrophy by restoring the dystrophin gene. This promising therapy is advancing toward clinical trials.
Area of Science:
- Biochemistry
- Genetics
- Molecular Biology
Background:
- Duchenne muscular dystrophy (DMD) is caused by mutations in the dystrophin gene.
- Exon skipping is a potential therapeutic strategy to restore the dystrophin reading frame.
- Antisense oligonucleotides (ASOs) are key tools for inducing exon skipping.
Purpose of the Study:
- To review the advancements in ASO-induced exon skipping for DMD.
- To highlight the progress towards clinical applications.
- To discuss challenges and limitations of this therapeutic approach.
Main Methods:
- Review of in vitro and in vivo studies on ASO-induced exon skipping.
- Analysis of ASO chemistry advancements for stability and reduced toxicity.
- Examination of clinical trial progress for related applications.
Main Results:
- Induced exon skipping can address a significant percentage of dystrophin gene mutations.
- ASO chemistry has improved, leading to more stable and less toxic compounds.
- Several ASOs are in advanced clinical trials for other applications, demonstrating therapeutic potential.
Conclusions:
- ASO-induced exon skipping shows significant promise for treating DMD.
- Therapeutic strategies are progressing towards clinical trials.
- Further research is needed to overcome challenges and limitations for widespread clinical use.

02:18Alternative RNA Splicing
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

02:27Nonsense-mediated mRNA Decay
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

01:32RNA Splicing
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
02:32Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon has three reading...

01:21Satellite Stem Cells and Muscular Dystrophy
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
02:31Nuclear Export of mRNA
Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...
