Non-LTR Retrotransposons

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 Recombination

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...

Mechanisms of Retrovirus-induced Cancers

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

DNA-only Transposons

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...

Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
Some...

Summary

Transposable elements (TEs) in human genomes can drive cancer by causing mutations or rearrangements. However, TEs may also offer protection against cancer, with their mobility potentially influenced by the cancer environment itself.

Background:

Transposable elements (TEs), mobile DNA sequences, are prevalent in eukaryotic genomes, including humans.
TEs significantly influence genome evolution by contributing to genetic diversity.
TE mobility can lead to detrimental genetic alterations, such as mutations, gene disruptions, and chromosomal rearrangements, implicated in various diseases, including cancer.

Purpose of the Study:

To review the dual role of transposons and retrotransposons in human cancer.
To explore how TEs may genetically cause cancer onset.
To examine the potential protective effects of TEs against cancer.

Main Methods:

Literature review of studies on transposable elements and cancer.
Analysis of the mechanisms by which TEs impact genome stability.
Investigation of the interplay between the cancer cell environment and TE activity.

Main Results:

TEs can act as mutagens, promoting cancer development through genomic instability.
Conversely, TEs might possess anti-cancer properties, though mechanisms are less understood.
The tumor microenvironment may induce or exacerbate TE mobility.

Conclusions:

Transposable elements have a complex and often contradictory relationship with human cancer.
Understanding TE dynamics is crucial for comprehending cancer etiology and developing novel therapeutic strategies.
Further research is needed to elucidate the precise roles and regulatory mechanisms of TEs in cancer.
