Insights

Alternative splicing, a key gene regulation process, generates variants impacting cancer and genetic disorders. Antisense oligonucleotides offer a promising therapeutic strategy by modulating these splicing patterns.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Over 35% of human genes utilize alternative splicing, a crucial regulatory mechanism.
  • Dysregulated splicing patterns yield splice variants with altered functions, implicated in diseases.
  • Aberrant splice variants are linked to cancer, including cell death, proliferation, and angiogenesis.

Purpose of the Study:

  • To review cancer-associated alternatively spliced genes.
  • To explore the role of alternative splicing in genetic disorders like beta-thalassemia, cystic fibrosis, and muscular dystrophy.
  • To discuss antisense oligonucleotides (ASOs) as a therapeutic approach for modulating alternative splicing.

Main Methods:

  • Review of literature on alternative splicing in cancer and genetic diseases.
  • Identification of key alternatively spliced genes relevant to disease pathology.
  • Discussion of ASO chemistry and delivery strategies for therapeutic applications.

Main Results:

  • Several cancer-related alternatively spliced genes and their functions are highlighted.
  • The association of alternative splicing with genetic disorders is detailed.
  • Potential gene targets for ASO-based splicing modulation are identified.

Conclusions:

  • Alternative splicing plays a significant role in various cancers and genetic disorders.
  • Antisense oligonucleotides represent a viable therapeutic strategy for correcting aberrant splicing patterns.
  • Further research into ASO chemistries and delivery is essential for clinical translation.

RNA 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...

Alternative 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...

siRNA - 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...
Experimental RNAi02:15

Experimental 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...
