Studying the muscle stem cells in boys suffering fromDuchenne muscular dystrophy, Stanford scientist Helen Blau found that their telomeres–the protective caps at the end of chromosomes–were unusually short. Now, in a new study, Blau and a small group of colleagues say that they have developed a method to use modified messenger RNA to lengthen telomeres, opening a pathway to countering the effects of aging in cells–a process that might apply to a range of diseases from DMD to diabetes and heart disease.
Telomeres naturally shorten every time a … Read more
