Research Interests

The main goal of the Ashcroft laboratory is to understand the key cellular mechanisms involved in oxygen sensing and hypoxia signalling in mammalian cells. In particular, we have a strong interest in the hypoxia inducible factor (HIF) family of transcription factors and their role in cancer, renal disease and cardiovascular disease.


Research Aims

Our main goals are to:

1) Evaluate known and novel regulators of the hypoxia/HIF signalling with particular focus on link between mitochondria and the cellular oxygen-sensing machinery.

2) Investigate the key cellular mechanisms regulating hypoxia/HIF signalling in mammalian cells and elucidate how these are mechanistically linked to disease.

3) Identify and develop strategies to exploit hypoxia/HIF signalling in disease.
