Investigating Changing Gene Expression With Age

A brief release from EurekAlert! is illustrative of the spread of examining changes of gene expression with aging. That knowledge should provide a starting point for further research to understand why tissues act differently with age, as well as the root causes of these changes. In this case, the tissue in question is skin: researchers aim "to identify how genetic expression in the skin changes with ageing and how it can affect the comparative healing and scarring rates of older and younger people. Findings from the study will go towards achieving our ultimate goal of reducing the disfigurement associated with burn injury. We also hope to gain important knowledge for the development of tailored burns treatments based on an individual's unique combination of genes." Sooner or later, tracking down the whys and wherefores for all the biochemical changes that make up age will produce sufficent knowledge and tools to do something about age-related degeneration and death.
