Dr Opher Gileadi tells us how cells maintain genome integrity and how we can use it in our fight against cancer. While cigarette smoke and sun exposure can lead to DNA damage, which causes cancer, there are a number of natural processes within the body that can also lead to cell mutations. Dr Opher Gileadi studies the structure and chemical biology of the proteins involved in DNA repair and in recovery from DNA damage. Since DNA damage can be both a cause of cancer and a tool in fighting cancer, Dr Gileadi aims to uncover ways to better target and destroy cancer cells.
