Bioinformatics and Epidemiology of the Epigenetic Clock & Heart Failure

1 PhD project offered in the IPP winter call 2020/2021

Scientific background

Organismic ageing is accompanied by changes in the level of DNA cytosine methylation. These changes are so stereotypic that “epigenetic clocks’ have been developed, whose methylation level tightly correlates with biological age, most famously ‘Horvath’s clock’.  These epigenetic clocks predict biological age and inform about positive or negative deviation of biological from chronological age, as well as predicting time to death.

PhD project

In an interdisciplinary project, we will investigate the utility of Horvath’s clock in studying the common age-associated disease of heart failure (HF), a syndrome that shows growing prevalence due to increasing life expectancy and demographic change. HF represents a high medical and economic burden and is the most frequent cause of hospitalization. There are distinct HF-phenotypes with varying outcome, the mechanisms of which are poorly understood. To stratify HF and predict patient outcomes we will employ Horvath’s clock as a molecular parameter.

In this project, you will establish the computational analysis employing Horvath’s clock and use it to calculate the epigenetic age a cohort of HF patients. You will correlate epigenetic age with available clinical parameters to stratify patients, predict disease outcome, and develop computational tools that improve treatment regimes. The project will be pursued in close collaboration with Prof. Philipp Wild  at the University Medical Center (Preventive Cardiology). The successful candidate will have a strong background in Computational Biology, Bioinformatics, and/or Epidemiology.
