Description of Research

Lauren Endres received her Ph.D. from the University of Toronto, where her research focused on understanding the role that tumor suppressors play in processes that determine cancer cell fates. Dr. Endres continued research in cancer biology as a post-doc, first at Harvard Medical School and then at the State University of New York’s Polytechnic Institute (SUNY Poly), where she later accepted a faculty position. Dr. Endres's research aims to understand translational mechanisms that protect against oxidative stress with implications for cancer prevention and stemming its progression from a benign to a malignant state. Specifically, she investigates tRNA methyltransferases that are reactive oxygen species responsive and show deregulated expression in cancer. Ultimately, Dr. Endres aims to understand the interrelationships between these fascinating enzymes, their catalytic modifications, and known oncogenic and tumor-suppressive signaling pathways.

Research Description

The broad goal of my research program is to understand translational defense mechanisms that protect against oxidative-stress, with implications for the prevention of cancer and its progression from a benign to a malignant state. Specifically, I am investigating tRNA methyltransferases that are reactive oxygen species responsive and that show deregulated expression in a number of cancers, including colon, bladder, breast and ovarian. I aim understand the interrelationships between these fascinating enzymes, the modifications they catalyze, and known oncogenic and tumor suppressor signaling pathways.
