The non-coding genome in cardiac ageing and regeneration

Since the completion of the human genome project the number of protein-coding genes has been gradually corrected down to ~20,000 genes, or roughly the same number of genes found in the roundworm C. elegans. During the past decade, it became increasingly evident that the bigger part of our genome, which was considered ‘Junk DNA’, is actively transcribed into non-coding RNAs. Especially, in vertebrates ncRNAs are currently emerging as pivotal players in virtually all biological processes where they are believed to contribute significantly to biodiversity and disease susceptibility including cardiovascular ageing and disease. Our group is interested in identifying functional ncRNAs which play crucial roles in the processes of neonatal heart regeneration as well as cardiac ageing. Since telomere biology is directly associated with ageing and regeneration we are further interested in the link between ncRNAs and telomere dynamics. Our vision is the therapeutic exploitation of ncRNA and telomere biology aiming to enhance mammalian cardiomyocyte proliferation, thus boosting cardiac regeneration to combat heart disease.
