DNA damage is believed to represent the initiating step in chemical carcinogenesis. Our laboratory seeks to understand how specific DNA adducts perturb DNA structure and how these structural interfere with the biological processing of DNA. One goal is to understand the basis whereby chemical modification of DNA triggers specific mutations. Some mutations, especially those occurring in proto-oncogene sequences or tumor suppressor gene sequences, play crucial roles in the process of chemical carcinogenesis.
