Telomeres, regions of the DNA located on the ends of chromosomes, play an important role in cell division, carcinogenesis and aging. Their biological function can be disturbed by oxidative damage, which was thought to be solely caused by the interaction of DNA with other molecules acting as oxidants. Researcher in our institute show [collaboration] that low-energy ultraviolet light, absorbed directly by telomeric DNA, generates radicals leading to oxidative damage.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
