jumping genes

Researchers find many tumor-specific antigens form when cancer genes and transposable elements link up.

Transposons may be key players in how tumors develop and spread, but they also keep cancer at bay in some circumstances.

Genetic studies have made it clear that eukaryotic horizontal gene transfer can and does happen. Exactly how, though, remains speculative.

Horizontally transferred genes play significant roles in eukaryotic genomes

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

This year revealed just how much scientists have learned about the disease, from how animals become naturally cancer-resistant to how tumor cells harness extracellular DNA to develop rapid drug resistance.

Activation of retrotransposons in the animals’ cancerous cells sets off an innate immune response that triggers cell death.

A new study suggests that DNA synthesized in the cell cytoplasm drives retinal cell death in an advanced form of age-related macular degeneration, a leading cause of blindness.

A transposable element that jumped into the TBXT gene, which is linked to tail morphology, appears to be to blame for our missing appendage.

A tool for identifying jumping gene insertions in DNA sequencing data turns up possible explanations for four patients’ rare developmental disorders.

The study could pave the way for transplanting porcine organs to humans without the risk of reigniting endogenous retroviruses.

Transfer RNA fragments prevent jumping genes from hopping around in the mouse embryo, when histone methylation can’t do the job.

A transposon underlies this classic story of evolutionary adaptation.
