Objetivos: Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare genetic disease (prevalence: 1 in 20 million) characterized by multiorgan defects, accelerated aging, and death at an average age of 14.6 years mainly from myocardial infarction or stroke. It is caused by a heterozygous de novo point mutation in the LMNA gene leading to the synthesis of progerin, a permanently farnesylated prelamin A mutant protein. HGPS has no cure and clinical trials targeting progerin farnesylation showed increased mean survival of only ~1.6 years in treated patients. It is therefore urgent to develop new strategies to treat or cure HGPS.

TREAT-HGPS is a transnational 3-year program involving scientists from 4 European nations who will exploit existing HGPS cell and mouse models to: a) discover novel combinations of therapeutic drugs to fight HGPS, and b) provide essential new knowledge about reversibility of progerin-induced damage.


1) Evaluate whether combinations of available drugs known to target either progerin (rapamycin, all-trans-retinoic acid, sulforaphane, trichostatin A) or progerin-induced effects (anti-IL6r antibodies) can synergize to ameliorate disease symptoms in cell and mouse models of HGPS. RNA interference strategies will be also tested.

2) Assess whether systemic progerin suppression at different time-points in the lifespan of progeroid mice reverses HGPS progression to ascertain the potential benefit of future approaches targeting progerin expression.

3) Evaluate whether progerin suppression restricted to vascular smooth muscle cells, main target of progerin, provokes overall beneficial effects in progeroid mice as an alternative approach to more challenging systemic progerin suppression.
