Polimorfismo I/D del gene per l'enzima di conversione dell'angiotensina (ACE): gene della longevità o fattore di rischio nella patologia ipertensiva?

In recent decades, the increase in life expectancy stimulated the study of aging processes and the search for candidate genes involved in longevity. The angiotensin converting enzyme (ACE), present in all endothelial cells, plays an essential role in maintaining the homeostasis of blood flow by regulating the production of the vasoconstrictor angiotensin II and inactivating the bradykinin. Some studies reported a possible association between the polymorphism I/D of ACE gene and either hypertension and longevity. The present study was aimed to confirm these data. We studied two large cohorts of nonagenarians and centenarians. One was from Sardinia (200 subjects, 88 males, mean age: 96 years)…
