Abstract: The current invention provides new methods and means for the prevention and treatment of ageing-related symptoms and diseases. The invention discloses Mannitol 5 and/or proline containing compositions that are particularly useful for the treatment of premature ageing related symptoms in mammalian subjects suffering from genetic defects in DNA damage response and genome maintenance pathways. Humans suffering from Cockayne syndrome (CS), Xerodema pigmentosum (XP), combined XPCS, trichothiodystrophy (TTD), COFS (cerebro-oculo-facio-skeletal syndrome), 10 XFE disorder (Xpf-Erccl syndrome), Bloom Syndrome (BS), Werner Syndrome (WS), Ataxia telangiectasia (AT), Fanconi Anemia (FA), Hutchinson Guilford Progeria (HGP) may be treated with pharmaceutical compositions comprising mannitol and/or proline according to this invention.

Abstract: The current invention pertains to a method for screening and discovery of compounds capable of inhibiting, preventing, delaying or reducing genome maintenance disorders and consequences thereof, in particular ageing related symptoms and disorders. The current invention provides a method for screening and discovery of compounds that are capable of inhibiting, preventing, delaying or reducing genome maintenance disorders and consequences thereof. The invention exploits animal models that comprise deficiencies in their genome maintenance systems, such as DNA repair systems, and display premature, enhanced, accelerated or segmental ageing phenotypes. These animal models can be advantageously applied to screen compounds and thereby develop schemes of intervention to treat, delay, inhibit, prevent or cure ageing related symptoms. The current invention thus provides a new and powerful tool to screen aid/or discover therapeutically active compounds to treat ageing related symptoms and diseases.
