In 2003, Nicolas Lévy and his team identified the cause of the disease when they discovered the involvement of the LMNA (nuclear protein-coding) gene, lamin A/C. Progeria is a rare genetic disease. Have any problems using the site? . Researchers are continuing their efforts in an attempt to counter the consequences of the genetic defect that causes progeria. To generate a model of this kind, Spanish and French researchers decided to introduce a gene mutation (G609G), equivalent to that identified in humans (G608G), in mice to reproduce the exact pathological mechanism found in the children, with a view to then blocking it. Thank you for taking your time to send in your valued opinion to Science X editors. Apart from any fair dealing for the purpose of private study or research, no To study this aspect, researchers needed to obtain a relevant animal model. This approach made it possible to obtain young mice that produced progerin, characteristic of the disease in humans. The research, published on 26 October 2011 in Science Translational Medicine, received backing from the AFM thanks to donations from a Telethon.. Progeria is a rare genetic disease. Materials provided by INSERM (Institut national de la santé et de la recherche médicale). In 2003, a team directed by Nicolas Lévy discovered the gene, and, in 2008, 12 children were able to begin clinical trials in which two molecules were combined to slow down the characteristic effects of the disease: premature aging.

The treatment is based on a combination of two existing molecules: statins (prescribed in the treatment and prevention of atherosclerosis and cardiovascular risks) and aminobisphosphonates (prescribed in to treat osteoporosis and to prevent complications in some forms of cancer). Les résultats ont été communiqués aux patients lors d’une réunion en mars 2013. La progéria ou maladie de Hutchinson-Gilford est une maladie du vieillissement accéléré rarissime (environ 20 patients vivants recensés en Europe). Bekijk deze video van Ashley die, in slechts 90 seconden, schittert met haar heldere persoonlijkheid en inzichtelijk advies aan andere kinderen met Progeria - … "This technology, explains Nicolas Lévy, is based on introducing a synthetic antisense aglionecleotide into mice. C'est un essai qui se déroule dans un seul centre en France (Marseille). However, although this treatment aimed to slow down the development of the disease, it did not reduce the quantities of progerin. For several years, research has been conducted in close collaboration from teams led by Nicolas Lévy and Annachiara De Sandre-Giovannoli at Inserm/Université de la Méditerranée and from a team led by Carlos López-Otín (University of Oviedo) and has succeeded in making such a model possible.

As is the case with progeria, this sequence is applied to block (or facilitate) the production of a functional protein using a gene. For several years, research has been conducted in close collaboration from teams led by Nicolas Lévy and Annachiara De Sandre-Giovannoli at Inserm/Université de la Méditerranée and from a team led by Carlos López-Otín (University of Oviedo) and has succeeded in making such a model possible. After three weeks alive, the mutated mice displayed growth defects, weight loss caused by bone deformation and cardiovascular and metabolic anomalies mirroring the human phenotype and considerably reducing their lifespan (an average of 103 days compared with two years for wild mice).

L'objectif de cet essai, soutenu financièrement par l'AFM-Téléthon, est d'évaluer la tolérance et l’efficacité de l’association pravastatine et acide zolédronique sur le poids, la taille et le métabolisme osseux chez 15 personnes atteintes de progéria, âgées de plus de 3 ans.
