Armanios led, shows that the telomere story is no exception. And a paper published Thursday in the New England Journal of Medicine, with results of a study that Dr. “And the longer the better.”īut, of course, nothing in biology is so simple. Mary Armanios, professor of oncology at Johns Hopkins University School of Medicine and director of the Telomere Center at the medical school’s Sidney Kimmel Comprehensive Cancer Center. “Short telomeres were thought to be bad - people with premature aging syndromes had short telomeres - so, by analogy, long telomeres were thought to be good,” said Dr. Every time a cell divides, its telomeres get a little shorter, until finally they get so short that the cell dies. The caps on chromosomes, called telomeres, are chains of short, repeated segments of DNA. The clocks come in the form of caps on the end of chromosomes - the long twisted strings of DNA carrying the cells’ genes. Stop the cell clocks and you can remain youthful. And the same should go for people, who are, after all, made from cells. If you can just stop the clock, cells can live indefinitely. Cells have a molecular clock that determines how long they live. The story, as often happens in science, sounded so appealing.
