Insights

Researchers discovered two new splicing variants of the RON proto-oncogene in colon cancer. These variants, involving exons 4-7 and introns 4-6, may contribute to cancer progression but have not yet been detected.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • The RON proto-oncogene plays a role in cell dissociation, migration, and invasion.
  • A known splicing variant, RON∆160, is found in colon cancers and promotes cellular transformation and tumor formation.
  • Understanding RON splicing variants is crucial for cancer research.

Purpose of the Study:

  • To identify and characterize novel splicing variants of the RON gene.
  • To investigate the structural differences and potential implications of these new variants in cancer.

Main Methods:

  • Analysis of alternative splicing events in the RON gene.
  • Identification of novel splicing variants involving exons 5 and 6.
  • Comparison of the structural features of the identified variants.

Main Results:

  • Two novel RON splicing variants were identified, characterized by the inclusion of exons 4-7.
  • Both variants include intron 4 and intron 5, but differ in the inclusion or skipping of intron 6.
  • These variants are predicted to be truncated, but the corresponding proteins have not yet been detected.

Conclusions:

  • The discovery of these novel RON splicing variants expands our understanding of RON gene regulation in cancer.
  • Further research is needed to detect these truncated proteins and elucidate their functional roles in colon cancer progression.

RNA Splicing01:32

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...

Ribosome Profiling02:24

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique helps...
