A long and healthy life is not for everyone. Why is one person worn out at the age of sixty while another can still cycle at the age of ninety? The Molecular Epidemiology department of the LUMC conducts research into the origin of these differences and how these differences can be reduced.

What affects the aging rate? Which mechanisms play a role in this? To investigate this, the researchers are looking at factors that cause people to age healthily. To this end, research is being conducted in long-lived families. In these families the majority manage to reach the age of ninety. What is their secret? Which genes are beneficial? What makes their bodies different from other people? Within this context, we focus on a healthy metabolism, disease and osteoarthritis.

Molecular Epidemiology combines expertise in molecular epidemiology and computer science. This expertise is used for research, education and advice in order to contribute to the improvement of healthcare.

The mission of the research conducted within Molecular Epidemiology (MolEpi) is to monitor and understand factors that influence the risk of age-related disease(s) – aging – or the inverse factors involved in healthy aging. To this end, we generate and analyze state-of-the-art molecular data in human populations, families and groups of patients. In addition, in this context we focus on metabolic health and the relationship to cardiovascular disease. The research is anchored in themes and is carried out in three related research areas and the associated study populations: Aging osteoarthritis and epigenetic epidemiological research. The populations involved in these studies are also linked in biobanks within the BBMRI community.

New publication shows blood biomarkers for senescence endotypes in osteoarthritis patients

When cells reach a permanent growth arrest (Senescence) and resist death, this can result in numerous diseases, such as osteoarthritis. Here we show the presence of two different types of senescence in the blood metabolome of osteoarthritis patients. These blood metabolome patterns could function [...]

Leiden master’s student cracks epigenetic clock that predicts age – newsitem LUMC 14-01-2022

Researchers can accurately determine how old a person is based on the calibration of the DNA. To do this, they use a so-called epigenetic clock. Master's student Thomas Jonkman has now, nine years after the discovery, unravelled how this clock exactly works: it turns [...]
