The National Cancer Institute of Maryland has identified some processes behind progeria syndrome. This syndrome occurs in young and young children (about a year and a half) adopt the form of older people: they fight their hair, mock, have osteoporosis and arteriosclerosis, etc. Since 2003 they knew that the disease-causing protein is progerine, a defective version of lamin A. Now, the skin cells of these patients have grown in cultures and studied the influence of progerin on gene activity. They have seen that this protein affects more than a thousand genera and have discovered some damage to molecules and cells.
