Heart attacks treated with new gene therapy based on telomerase enzyme

The enzyme telomerase repairs cell damage produced by ageing, and has been used successfully in therapies to lengthen the life of mice. Now it has been observed that it could also be used to cure illnesses related to the ageing process. Researchers at the () have for the first time treated with telomerase by designing a very innovative strategy: a that reactivates the telomerase gene only in the heart of adult mice, thus increasing survival rates in those animals by 17 % following a .
