Molecular Genetics of Ageing
Ageing is defined as a gradual decline of organismal homeostasis and of physiologic functions throughout the body, and is associated with an increased risk of age-related disease. Yet work from model genetic organisms reveals that animals possess natural defense mechanisms that help stave off ageing, increase organismal homeostasis and stimulate longevity. [more...]
