telomere

New research reveals how cells prevent telomerase from meddling with double-stranded breaks.

Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

Lizards born to parents that experienced persistent heat had shortened telomeres, a genetic weathering that typically happens with age but can also be exacerbated by stress.

The science isn’t there yet, nor are the known interventions that ought to be combined with delivering such predictions.

Telomeres in cancer cells exposed to oxidative stress got shorter and stickier.

Data don’t support many direct-to-consumer products, from telomere assessments to bespoke diets based on genetic sequences.

Researchers find that while bats in the Myotis genus don’t produce telomerase, the enzyme that lengthens telomeres, they possess 21 telomere maintenance–related genes.

An accumulation of stressful events in childhood is associated with shorter telomeres as a person ages, researchers report. 

Endurance exercise and metabolism are linked to transcriptional activation of human telomeres, researchers propose.

Researchers identify a novel protein that helps maintain the length of chromosome-capping telomeres. 

Reduction in telomere length is associated with stress early on in life and may have a genetic component, researchers find.

Former biotech executive files lawsuit accusing the company of engaging in deceptive business practices.
