Subarea 3: Genetics and Epigenetics of Aging

The focus of Subarea 3 is on genetic and epigenetic determinants of life- and health span as well as aging in fish, rodents and humans. This line of research builds on the expertise of the institute in comparative and functional genomics.

The research is defined by five focus areas:

  • Comparative genomics in short- and long-lived models of aging,
  • Genomic engineering in N. furzeri,
  • Epigenetics of aging,
  • Non-coding RNAs in aging, and
  • Comparative transcriptomics of aging.

Research focus of Subarea 3.

To uncover causative factors for aging, comparative genomics in short- and long-lived model systems are applied. Functional genomics is used to identify novel pathways contribute to aging of an organism and to validate the functional relevance of genetic and epigenetic changes that occur during aging. Furthermore, genetic risk factors for aging-related diseases are identified and functionally tested. The future development of the Subarea aims to integrate changes in host-microbiota interactions during aging, and how these influence clonal mutation and epigenetic alterations through metabolites and other signals.
