摘要
Genetic mutations that lead to an accumulation of farnesyl-prelamin A cause progeroid syndromes, including Hutchinson-Gilford progeria syndrome. It seemed possible that the farnesylated form of prelamin A might be toxic to mammalian cells, accounting for all the disease phenotypes that are characteristic of progeria. This concept led to the hypothesis that protein farnesyltransferase inhibitors (FTIs) might ameliorate the disease phenotypes of progeria in mouse models. Thus far, two different mouse models of progeria have been examined. In both models, FTIs improved progeria-like disease phenotypes. Here, prelamin A post-translational processing is discussed and several mutations underlying human progeroid syndromes are described. In addition, recent data showing that FTIs ameliorate disease phenotypes in a pair of mouse models of progeria are discussed.
