Découverte de nouvelles formes génétiques rares de l’obésité

L’équipe de Ralf Jockers et Julie Dam fait partie d’un réseau européen de prévention de l’obésité de l’enfant, OBELISK, lancé en mai 2023. Conçu et dirigé par une équipe multidisciplinaire de l’UFR3S Université de Lille, du CHU de Lille, de l’Inserm et de l’Institut EGID, OBELISK réunira pendant 5 ans 14 équipes de recherche dans 10 pays européens, avec un objectif : diminuer de 35% le nombre d’enfants et d’adolescents européens en surpoids.
Dans ce cadre et en synergie avec leurs collaborateurs, le projet de Ralf Jockers et Julie Dam consistera à identifier de nouveaux gènes liés à l'obésité, en mettant un accent particulier sur les récepteurs couplés aux protéines G (RCPG). Ces récepteurs font partie d'une vaste famille de récepteurs qui présentent un fort potentiel thérapeutique étant la cible de plus d’un tiers des médicaments existants. Actuellement, deux d'entre eux, le GLP1R et le MC4R, sont spécifiquement ciblés par de nouveaux médicaments anti-obésité très prometteurs. Un deuxième objectif de ce projet consistera à établir un programme de prédiction capable d'évaluer l'impact fonctionnel des mutations de ces récepteurs, trouvés chez l’homme. Ainsi les découvertes issues de ce projet pourraient contribuer à la mise en place d'une approche médicale personnalisée.

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.
