Telomeres explained as an analogy to aglets, the tips that keep shoe laces from unravelling. Glutathione slows down telomere shortening. -
Telomeres are such an important discovery and a key to our aging. The DNA molecule is packaged into In the nucleus of each cell, and is found in thread-like structures called chromosomes. Protecting each of your chromosomes at the end is a structure ca... -

(Visit: http://www.uctv.tv/) Telomeres were first recognized in the late 1930s as important structures on chromosome ends. In the 1970s the sequence of these structures was identified in the ciliated protozoa Tetrahymena by Elizabeth Blackburn. In the ... -
Watch how stress effects our genes! The genetic structures called telomeres protect the ends of our chromosomes from fraying. As we age, our telomeres shorten. Stress by way of stress hormones accelerate the shortening of telomeres. A telomere is a reg... -

As normal cells divide, the ends of their chromosomes (telomeres) progressively shorten until eventually the cells reach senescence or undergo apoptosis. Cancers, which disproportionally kill more individuals in the 65 years or above age group, often o... -
