Elizabeth Blackburn

Elizabeth Blackburn was awarded the 2009 Nobel Prize in Physiology or Medicine for discovering the molecular structure of telomeres and the telomerase enzyme. Her work revealed how telomeres protect chromosome ends and how telomerase maintains them — discoveries directly relevant to cancer, where telomerase is reactivated to enable unlimited replicative potential, one of the hallmarks of cancer. Her research illuminated why cancer cells do not senesce and opened telomerase as a cancer therapeutic target. She also contributed to the foundational understanding of cellular aging and stress biology.
