Results from the new study, reported in the Proceedings of the National Academy of Sciences (PNAS) have shown that telomerase is reactivated in normal adult cells at the latter stage of cell aging, and this activity reduces the potential for DNA damage that could lead cells to become cancerous. “This study reshapes the current understanding of telomerase’s function in normal cells,” said Kan Cao, PhD, an associate professor of cell biology and molecular genetics at UMD, who is senior author of the study. “Our work shows, for the first time, that there is a role for telomerase in adult cells beyond promoting tumor formation.
University of Maryland-led team found that telomerase, which immortalizes cancer cells, also prevents tumors and slows a key stage in normal cell death.
