Life Extension

This book looks at aging through research on Drosophila, the fruit fly that is one of the most widely used model organisms in biogerontology. Work in model organisms can expand the theoretical knowledge of aging: it yields valuable insight into the molecular and cellular processes that underlie aging process, and it can perhaps provide new therapeutic targets for the treatment of age-related disorders in humans.

Drosophila models have been developed for a large variety of aging-related processes and diseases, and this book provides readers with an overview of current research on the use of the Drosophila model to understand the genetic, molecular and physiological mechanisms that underlie the aging process. Themes of healthspan, life extension and longevity-associated genes emerge in this collation of international research on Drosophila that is of relevance to geriatrics and gerontology, animal genetics and genomics, and biomedicine.

This fascinating, illustrated book will be of interest to a wide audience, ranging from academic researchers to the general reader.
