Five-year NIH-funded study will examine how early-life factors such as growth patterns and exposure to air pollution affect ...

Much like shoelaces have plastic tips on them to prevent fraying, our chromosomes are capped with structures called telomeres—sections of DNA that protect the chromosomes from damage. These protective ...

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, ...

Vitamin D is a real powerhouse. New research suggests this vitamin supports healthy aging, along with your immune system and ...
