UTMB’s Norbert Herzog and David Niesel report on last year’s winners of the Nobel Prize in Physiology or Medicine in this week’s installment of Medical Discovery News. The honors went to a trio of Americans who answered a fundamental biological question: How do cells reliably divide and reproduce? Their work was on something called telomeres and the protein that creates them called telomerase. What the trio discovered is that telomeres are integral to the cell’s ability to faithfully divide and reproduce. By understanding telomeres and telomerase, it’s possible we could delay aging and discover new ways to fight cancer. This discovery has profoundly transformed our understanding of biology and medicine. MDN airs locally at 10 a.m. Saturday on KUHF.
