telomeres

In PNAS this week: characterization of an alternatively spliced autism-linked gene, horizontal gene transfer in soil bacteria, and more.

The researchers reported that most of these changes, though not all, reverted to normal upon the astronaut's return to Earth.

The assay will use Genomic Vision technology and be used to study the role of telomere length in complex diseases.

The companies will co-fund a new study of the 3DS technology, and MDxHealth will have the option to exclusively license the telomere-based test.

Long Lives of Bats

Researchers report that the telomeres of a long-lived bat don't shorten with age.

A null mutation in the SERPINE1 gene was associated with longer telomeres and increased longevity among carriers, a new study found.

Salmon with shorter telomeres survive to make the trip back to their river homes, New Scientist reports.

Chromosomes

The firm's first assay will be for Hodgkin lymphoma, but a liquid biopsy test for prostate cancer has also shown strong predictive power in initial validation data.

Researchers found that telomeres were shorter in tumors than in normal tissues and longer in sarcomas and gliomas than in other cancers.

In Genome Research this week: molecular autopsies for sudden death, telomere methylation in Arabidopsis, and more.
