Discovery of new rare genetic forms of obesity

Research

Ralf Jockers and Julie Dam's team is part of a European network for the prevention of childhood obesity, OBELISK, launched in May 2023. Designed and led by a multidisciplinary team from UFR3S University of Lille, Lille University Hospital, Inserm and the EGID Institute, OBELISK will bring together 14 research teams in 10 European countries for 5 years, with one objective: to reduce the number of overweight European children and adolescents by 35%.
Within this framework and in synergy with their collaborators, Ralf Jockers and Julie Dam's project will consist of identifying new genes linked to obesity, with particular emphasis on G protein-coupled receptors. These receptors are part of a large family of receptors that have strong therapeutic potential being the target of more than a third of existing drugs. Currently, two of them, GLP1R and MC4R, are specifically targeted by very promising new anti-obesity drugs. A second objective of this project will be to establish a prediction program capable of evaluating the functional impact of mutations of these receptors, found in humans. Thus, the discoveries resulting from this project could contribute to the implementation of a personalized medical approach.

Preventing childhood obesity to stay healthy throughout life

Rates of childhood obesity are increasing at an alarming rate. According to the WHO European Regional Obesity Report 2022, roughly 1 in 3 primary school-aged children in Europe is living with obesity or overweight. This figure is predicted to rise even further. Children and teenagers with obesity and overweight carry an increased risk of developing poor health outcomes in later life including severe obesity, diabetes and cardiovascular disease leading to disability and premature death.

Treating adults with obesity and overweight is challenging and it is proven that both prevention and treatment work better in younger age groups. A new European project is embarking upon an ambitious research programme aimed at preventing childhood obesity to ‘cut the roots’ of the current pandemic. The OBELISK project has developed an approach built on four principles, hence reference to the four-sided structure we are all familiar with: Prediction, Prevention, Precision, and Participation.

OBELISK aims to deliver scientific breakthroughs to enhance our understanding of the molecular mechanisms by which causative factors interact to drive (or prevent) the transition from normal weight to obesity during childhood. This knowledge will be used to develop and exploit new predictive tools and preventative treatments. Research teams will also seek to identify new genes associated with childhood obesity, providing the opportunity to develop new drug treatments. The project will demonstrate the effectiveness of targeted approaches to prevent childhood obesity, including trialling new treatments to reverse obesity in children who have mutations, and are therefore predisposed to the early development of severe obesity. Finally, underpinning the entire project is a participatory approach to both the research and dissemination of the project results, including the roll out of educational programmes, through engaging with families and carers, day care providers and schools, local authorities, the healthcare industry as well as policymakers and the scientific and academic communities.

This ambitious project includes 15 partners from universities, research institutions and small and medium-sized enterprises from across nine European countries. The consortium has received 9.5 million Euro from the EU’s Horizon Europe Research and Innovation programme and an additional 1.7 million Euro from UK and Swiss research funding bodies. The project is coordinated by French research institute INSERM, led by the centre in Lille and the consortium have met today to initiate the project and embark upon their five-year collaboration.

Project coordinators Philippe Froguel and Amélie Bonnefond say “we are excited to be working with this diverse and expert consortium to help address the challenges of childhood obesity and its adverse impacts on the future health of European citizens. We are committed to delivering the scientific innovations needed to develop more effective tools and treatments for prediction and prevention, and the project will deliver precise guidelines and educational materials to a range of stakeholders through our participatory approach”.

OBELISK started on 1st May and a public website will be launched in October 2023. In the meantime, to keep up to date with the project’s progress please follow @ObeliskProjectE on Twitter.
