Research from other scientists at Johns Hopkins, he says, had suggested that some tumors, particularly those that affect the nervous system, have mutations in the ATRX gene, which produces proteins that appear to maintain the length of telomeres, repetitive segments of DNA on the ends of chromosomes that typically shorten each time a cell divides.
The telomeres are located at the ends of the chromosomes, and affect the lifespan and health of an individual.

Telomere length predicts both cellular health and disease in rodent models and humans.8 Shorter telomeres predict onset of cardiometabolic diseases of aging.9 Chronic stress is associated with higher inflammation, shorter telomeres, and lower activity levels of telomerase, the cellular enzyme that elongates telomeric DNA.10, 11 Levels of amyloid beta (Aβ) proteins circulating in the blood appear to be stress - related in rodent models12 and may be affected by stress reduction, and greater Aβ42 / Aβ40 ratios are associated with lower risk of dementia.13
«Our findings reveal a critical role for telomere length in a mouse model of age - dependent human disease,» said first author Christina Theodoris, an MD / PhD student in the laboratory of Deepak Srivastava, MD. «This model provides a unique opportunity to dissect the mechanisms by which telomeres affect age - dependent disease and also a system to test novel therapeutics for aortic valve disease.»
The scientists think that telomere length affects disease severity by changing gene expression in pathways implicated in CAVD, such as anti-inflammatory and anti-calcifications pathways.
Erosion of telomeres has long been associated with diseases of aging, but how telomere length affects human disease has remained largely a mystery.
Telomeres work to keep chromosome ends from deteriorating or fusing with a neighboring chromosome, affecting how quickly cells age and die.

His research showed that comprehensive lifestyle changes affect gene expression, «turning on» disease - preventing genes and «turning off» genes that promote cancer and heart disease, as well as the first controlled study showing that these lifestyle changes may begin to reverse aging by lengthening telomeres, the ends of our chromosomes which control aging (in collaboration with Dr. Elizabeth Blackburn, awarded the Nobel Prize in Medicine).
