Recently it has been proposed that the DNA damage response acts as a barrier mechanism during the early stages of tumourigenesis. Markers commonly phosphorylated as a result of an active DNA damage pathway were identified in pre-neoplastic lesions and have been attributed to the early activation of oncogenes. Our hypothesis suggests that along with the activation of oncogenes, the DNA-damage response pathway could be initiated by other factors during early tumour progression, for example, oxidative changes to DNA bases, the production of reactive oxygen species and hypoxia. Regions of hypoxia arise due to the malformed vessels induced by tumour angiogenesis and occur early in the development of all solid tumours. Many elegant studies have demonstrated that the degree of hypoxia within human cancers correlates with poor prognosis as a result of a more aggressive phenotype as well as resistance to both chemo and radio-therapy. Significantly, red cell flux instability within a tumour can lead to rapid re-oxygenation and also induces a DNA damage response. My work has shown that both the ATR and ATM signal transduction pathways are activated by tumour hypoxia. The aim of my lab is to target the DNA damage response as a means of sensitizing cells to hypoxia/reoxygenation.
