The future of heart disease prevention? How your genome expresses itself

By AMERICAN HEART ASSOCIATION NEWS

The breakthrough made headlines in 2003: Scientists had mapped the DNA sequence that makes up the genetic code of humans. Since then, scientific discoveries and transformative technologies have ushered in a genomic era that continues to peel back layers of information about traits and diseases […]

Smoking leaves historical ‘footprint’ in DNA

By AMERICAN HEART ASSOCIATION NEWS

Smoking leaves its “footprint” in your DNA, according to research released Tuesday.

The new findings suggest that DNA methylation — a process by which cells control gene activity — could reveal a person’s smoking history and provide researchers with potential targets for new therapies.

Positive lifestyle changes could reverse aging on a cellular level

 Comprehensive lifestyle changes could increase the length of telomeres, the ends of chromosomes that control cell aging, according to a pilot study published in The Lancet Oncology. The findings may lead to a better understanding of how lifestyle changes could reverse aging on a cellular level. 

Telomeres are DNA-protein complexes at […]
