Research Topics

A number of age-related pathologies are associated with abnormal telomere length, suggesting that telomere defects may play a role in aging. It is believed that owing to its repetitive sequence, telomere can form unusual secondary structures (e.g., G-quadruplex and a lariat-like T-loop configuration), both of which impact telomere maintenance. We investigate the hypothesis that inadequate DNA structural resolution would impact telomere maintenance and function. Using a combination of molecular, genetic, and biochemical approaches, we are interested in probing (1) the key genes that modulate unique DNA secondary structures at telomeres; and (2) the contributions of DNA resolution deficiency to telomere defects in aging and premature aging syndromes. These studies will enhance our understanding of how DNA resolution deficiencies affect telomere maintenance and thus aging and related human diseases.


Dr. Yie Liu received her Ph.D. at Karolinska Institute, Sweden in 1995 and then joined the University of Toronto as a postdoctoral fellow of the National Cancer Institute of Canada. She became a principal investigator at NIA since 2006.
