The growing proportion of the elderly population represents an increasing socioeconomic burden, not least because of age-associated diseases. It is therefore increasingly pertinent to find interventions that may lead to interventions for age-associated diseases such as Alzheimer's, Parkinson's and cardiovascular diseases. Although the cause of aging is currently unknown accumulation of damage to our genome, the DNA, may be an contributing factor.

In the Scheibye-Knudsen lab we try to understand the cellular and organismal consequences of DNA damage with the aim of developing interventions. We have discovered that DNA damage leads to changes in certain metabolites and that replenishment of these molecules may alter the rate of aging in model organisms. These findings suggest that normal aging and age-associated diseases may be malleable to similar interventions. The hope is to develop interventions that will allow everyone to live healthier, happier and more productive lives.
