Insights

The Sleeping Beauty (SB) transposon system enables cancer gene discovery in mice. This technology identifies known and novel cancer genes and pathways driving tumor formation, aiding in potential drug target identification.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Genetics

Background:

  • The Tc1/mariner transposon, Sleeping Beauty (SB), can now be mobilized in mouse somatic cells.
  • High-frequency SB transposition in mice can induce tumors through insertional mutagenesis.
  • This process targets cancer genes, offering insights into tumor development.

Purpose of the Study:

  • To leverage SB insertional mutagenesis for identifying cancer-driving genes and signaling pathways.
  • To utilize a conditional SB transposition system for modeling specific human cancer types.
  • To discover novel cancer genes and potential therapeutic targets.

Main Methods:

  • Mobilization of the Sleeping Beauty (SB) transposon in mouse somatic cells.
  • Induction of tumors via SB insertional mutagenesis of endogenous genes.
  • Development and application of a conditional SB transposition system for targeted mutagenesis.

Main Results:

Transposons01:24

Transposons

Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...

DNA-only Transposons02:57

DNA-only Transposons

DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Overview of Transposition and Recombination02:13

Overview of Transposition and Recombination

Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
