Researchers find that UBQLN2 gene dysfunction causes a virus-like protein to accumulate in cells, which changes gene expression and may contribute to disease progression in amyotrophic lateral sclerosis (ALS).
Mice with overactive LINE-1 retrotransposons in their brains exhibit movement difficulties, suggesting the genetic elements may play a role in ataxia in humans.
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.
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.

While studying a degenerative eye disease, researchers find the first evidence that cells produce endogenous DNA in the cytoplasm. Drugs that block this activity are linked with reduced risk of atrophic age-related macular degeneration.

These mobile genetic elements can wreak havoc on the genome. Researchers are now trying to understand how such activity contributes to the aging process.
Scientists show that horizontal transfer of a particular DNA sequence among a diverse range of vertebrates is more widespread than previously believed.
