Systems Based Mechanisms of AgingProctor, Carole; Morgan, Amy; Mc Auley, Mark; Newcastle University; University of ChesterThe last number of decades have witnessed an unrelenting global rise in the number of older people. This demographic shift is laudable; however, many older people are burdened by poor health. The main reason so many older people have their healthspan compromised is due to the complex biology which underpins ageing and the diseases which are associated with this intriguing phenomenon. Fortunately, however, in recent years there has been a paradigm shift within biological research which has seen the emergence of systems biology. In contrast to a reductionist approach which was commonplace in biological research for many years, systems biology seeks to understand biological systems in an integrated manner. Investigating ageing and age related disease in this way is becoming increasingly effective. In this article we discuss the methods which underpin systems and provide examples of their application to biogerontology research.
