Dr Dean Craig Singleton
Dean Singleton obtained his BSc(Hons) in Biomedical Sciences at the University of Auckland and his PhD in Molecular Medicine and Pathology at the University of Auckland under the supervision of Associate Professor Adam Patterson and Professor Bill Wilson. He then completed a postdoctoral fellowship in the laboratory of Professor Adrian Harris at the Weatherall Institute of Molecular Medicine, University of Oxford, investigating transcriptional responses to tumour hypoxia. In 2014 he joined the laboratory of Dr Susanne Müller-Knapp in the Nuffield Department of Medicine, University of Oxford, developing chemical probes to target epigenetic proteins. In 2015 he was awarded the Rodney and Elaine Davies Cancer Research Fellowship to return to the University of Auckland.
Dr Singleton’s primary interest is in the development of antitumour agents that target tumour hypoxia with a focus on blocking the epigenetic reprogramming implicated in transcriptional responses to hypoxia.
Research | Current
My research aims to identify and develop new approaches to treat cancer. These projects include a combination of medicinal chemistry, functional genomics, cancer metabolism and cellular biology.
My current projects include:
- Can targeting glutamine metabolism destabilise HIF-1α in Triple receptor Negative Breast Cancer?
- Can targeting PERK (an immunosuppressive stress kinase) in immune cells restore antitumour immunity and enhance the activity of immune checkpoint therapy?
- Can whole genome CRISPR/Cas9 screens identify genes that are required for growth and survival of IDH1 mutant brain cancers?
