N-acetylcysteine might treat Progeria go to comments

Researchers found, in cultured cells, that N-acetylcysteine, a widely-used “drug” / food complement – “soaking up” reactive oxygen (among other things) – could prevent (some of?) the molecular damages occurring in Hutchinson Gilford progeria – a condition where children age up to eight times too quickly.
It hasn’t yet been given to children with the illness… A real full randomised clinical trial of the drug is not possible as the condition is so rare (78 cases worldwide!), but it could/will be tried.

Our findings suggest that un-repaired Reactive oxygen species – induced DNA double-strand breaks [= DNA damages] contribute significantly to the [restrictive dermopathy] RD and [Hutchinson Gilford progeria syndrome] HGPS phenotypes and that inclusion of [N-acetylcysteine] NAC in a combinatorial therapy might prove beneficial to HGPS patients.
