Scientific Interests

Dr. Oliver Hankinson's research focuses on the mechanism of carcinogenesis by environmental chemicals. Specifically, Hankinson studies polycyclic aromatic hydrocarbons (found in cigarette smoke and smog), dioxin (a widespread pollutant) and related compounds. Carcinogenesis by these compounds depends upon their binding to the aryl hydrocarbon receptor (AHR) and the subsequent dimerization of AHR with the ARNT protein. He is studying the molecular mechanism of activation of gene transcription by the liganded AHR/ARNT dimer (including the role of coactivator proteins in this process). In addition, he studies the impact of dietary fats (particularly omega-3 and omega-6 polyunsaturated fatty acids {PUFA}) on chemical carcinogenesis.

Current research projects include utilizing the CRISPR-Cas9 gene editing system to identify novel gene products required for transcriptional activation by the AHR/ARNT dimer and investigating the effects of dietary PUFA on cancer progression elicited by chemical carcinogens.
