Hope for Progeria - Successfully Validated on Mice, a Treatment Could Soon be Tested o...( PARIS June 30 /- Five years after...),Health

PARIS, June 30 /PRNewswire/ -- Five years after the identification of the gene responsible for progeria, a rare disease causing accelerated and premature ageing, a team of Spanish and French researchers (Carlos Lopez-Otin and coll. - University of Oviedo - and Nicolas Levy and coll. - Inserm/AP-HM, Marseille, France) have successfully demonstrated a treatment for the disease, using mice. This treatment, combining two existing pharmacological molecules, should slow down the progression of this disease which has hitherto remained untreatable.

Subject to the authorisation of health agencies, this treatment could very soon be tested on 15 children in Europe. This represents a major advance for the families affected by this disease and - more generally - for the understanding of the normal ageing process.

From identification of the gene to the development of treatment and the projected clinical protocol, this work - published in the review Nature Medicine - has received the financial backing of the Association Francaise contre les Myopathies (Muscular Dystrophy Association) thanks to French Telethon donations.

The treatment recently validated in mice is based on a combination of two existing pharmacological molecules: statins (indicated for the treatment and prevention of atherosclerosis and cardiovascular risks) and aminobisphosphonates (indicated for the treatment of osteoporosis). The Franco-Spanish researchers have demonstrated that this treatment attenuated the effects of the disease and significantly raised life expectancy.

As previously demonstrated by Nicolas Levy's team - which originally identified the gene in 2003 - progeria is due to the accumulation in the cells of a truncated protein, progerin, whose toxicity is linked to the presence of a fatty acid which remains fixed to the protein (whilst it is eliminated in normal cells). In order to inhibit or block the toxicity of progerin, the researchers explored the path of synth
