My research focuses on understanding the molecular and cell biology of the hypoxic microenvironment. Hypoxia (low oxygen) is key in many pathological settings including wound healing, inflammation, ischemia and cancer. Regions of hypoxia in tumours are associated with worse survival, chemotherapy and radiotherapy resistance. Tumour hypoxia arises from the combination of high metabolic and proliferative rates and aberrant vascularisation. The hypoxic tumour microenvironment is also acidic as metabolic acid accumulates in poorly-vascularised areas. Hypoxia induces a transcriptome shift under the regulation of the transcription factors HIF1α and HIF2α, which are stabilised in hypoxia. HIFs regulate genes in key "hallmarks of cancer" processes that enable adaptation to the hypoxic tumour microenvironment. In many cases anti-angiogenic therapy, such as bevacizumab, increases tumour hypoxia and hypoxic adaptation is a major mechanism of resistance to anti-angiogenic therapies. Understanding the molecular consequences of hypoxia and how to target hypoxic regions of tumours is key in improving tumour patient survival.
