By understanding the control of the fidelity of DNA replication in normal cells we aim to understand why defects in the proteins involved are associated with cancer. Her aim is to pinpoint differences between dividing tumour cells and dividing normal cells and determine which are important in cancer development. This has enabled the group to develop drugs which can specifically kill the tumour cells rather than just all dividing cells (personalized therapy). A separate side to Dr Bryant’s work is the development of novel transition metal-containing photodynamic therapy agents that bind to DNA and induce damage only upon irradiation with specific wavelengths of light. This is a collaboration with Prof. Julia Weinstein in the Department of Chemistry (TUOS).
