Scientists from the Institut Pasteur, CNRS, Institut Gustave Roussy and CEA, have succeeded in restoring normal activity in cells isolated from patients with the premature aging disease Cockayne syndrome. They have uncovered the role played in these cells by an enzyme, the HTRA3 protease. The team state that this enzyme is overexpressed in Cockayne syndrome patient cells, and leads to mitochondrial defects, which in turn … Continue reading Researchers identify and correct premature aging in diseased cells.
