I became more interested in genetics and DNA when I learned about my own genetic mutation, MTHFR, and how it can play a role in folate deficiency and my own health issues. Writing a medical book for ...

We don’t often, if ever, associate babies with aging. They may have adorable wrinkles, but those aren’t the same as the ones frequently associated with, say, an octogenarian. But the reality is that ...

The more exercise people get, the less their cells appear to age. In a new study in Preventive Medicine, people who exercised ...

In humans, telomeres are nucleoprotein complexes of tandem 5′TTAGGG3′ DNA repeats and associated proteins at the ends of all 46 chromosomes. Telomere loss beyond a certain threshold causes telomere ...

Some cells that do not produce telomerase are still able to maintain telomere length. Roger Reddel, [5] of the Children's Medical Research Institute in Sydney, Australia, is investigating this ...

Telomeres, the protective caps at the ends of chromosomes, are an important component of healthy aging. One study found that vitamin D supplementation helps to minimize the shortening of telomeres, ...

Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres - regions of repetitive DNA sequences and a protein structure - protect the tips of chromosomes from damage. Every ...
