Mon, 27 Mar 2017 00:00:00 EDTScientists at the Gladstone Institutes discovered a key mechanism that protects mice from developing a human disease of aging, and begins to explain the wide spectrum of disease severity often seen in humans. Both aspects center on the critical role of telomeres, protective caps on the ends of chromosomes that erode with age.
Mon, 27 Mar 2017 00:00:00 EDTA genetic trawl through the DNA of almost 100,000 people, including 17,000 patients with the most common type of ovarian cancer, has identified 12 new genetic variants that increase risk of developing the disease and confirmed the association of 18 of the previously published variants.
