Insights

Alternative messenger RNA (mRNA) splicing plays a key role in cancer initiation and progression. Understanding these splicing variants and targeting them offers promising new cancer therapies.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • Cancer is a leading global cause of mortality.
  • Genetic and epigenetic factors are well-studied in cancer, but alternative mRNA splicing is an emerging area of focus.
  • Alternative splicing patterns differ between cancer and non-cancer cells, influencing cancer development.

Purpose of the Study:

  • To review the role of alternative mRNA splicing in cancer initiation and progression.
  • To highlight how cancer cells are sensitive to drugs targeting the splicing regulatory network.
  • To discuss pathogenic splicing disruptions and their contribution to tumor progression.

Main Methods:

  • Review of existing literature on alternative mRNA splicing in cancer.
  • Analysis of examples of cancer-related alternative splicing events.
  • Discussion of therapeutic strategies targeting splicing.

Main Results:

  • Alternative mRNA splicing variants are distinct in cancer cells compared to normal cells.
  • Certain recurring splicing variants contribute to tumor progression.
  • Splicing disruptions can arise from mutations or altered balances of splicing variants.

Conclusions:

  • Alternative mRNA splicing is a significant contributor to cancer.
  • Targeting splicing regulatory networks presents a promising therapeutic avenue for cancer treatment.
  • Further research into cancer-specific splicing events can lead to novel treatment strategies.

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 Splicing02:18

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

What 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...

Nonsense-mediated mRNA Decay02:27

Nonsense-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,...
