Aging is not currently regarded as a disease, but researchers tend increasingly to view it as the common origin of conditions like insulin resistance or cardiovascular disease, whose incidence rises with age. In treating cell aging, we could prevent these diseases.

A short telomere represents a persistent and non-repairable damage to the cells, which is able to prevent their division or regeneration.

We believe that such a significant increase in longevity is due to the protective effect against cancer produced by caloric restriction - incidences fall by 40 percent if we compare them with the mice that produce more telomerase and have a normal diet - and, added to the presence of longer telomeres, this makes the mice live longer and better.

We see that mice that undergo caloric restriction show a lower telomere shortening rate than those fed with a normal diet. These mice therefore have longer telomeres as adults, as well as lower rates of chromosome anomalies.

It will be useful for you to know your biological age and maybe to change your lifestyle habits if you find you have short telomeres.

We can detect very small differences in telomere length, and it is a very simple and fast technique where many samples can be analysed at the same time. Most importantly, we are able to determine the presence of dangerous telomeres - those that are very short.
