Haematological Cancer Genetics

The Haematological Cancer Genetics team, headed by George Vassiliou, studies the genes and genetic pathways involved in the development of these cancers, with a particular emphasis on Acute Myeloid Leukaemia and Multiple Myeloma. The ultimate goal of the team is to help develop treatments that can improve the survival and quality of life of cancer sufferers.

Background

Blood cancers affect people of all ages worldwide. In recent years, our understanding of these cancers has improved dramatically as a result of advances made through scientific research. For some of the blood cancers, these advances have led to significant improvements in the survival and quality of life of sufferers. However, most blood cancers remain incurable and a lot more needs to be done before we are able to touch the lives of most patients. Our laboratory applies a number of approaches to facilitate this goal, focusing particularly on Acute Myeloid Leukaemia and Multiple Myeloma.

Research

We study the pathogenesis of haematological cancers using both in vitro approaches and in vivo models designed to closely mimic the human diseases, in order to assist in the development of targeted treatments. Recently we developed a mouse model of the commonest form of human Acute Myeloid Leukaemia (NPM1c +ve) and identified, using transposon-based insertional mutagenesis, molecular pathways that collaborate with NPM1 mutations to promote leukaemogenesis. We are currently testing therapeutic approaches against AML using these findings. Additionally, we are applying a similar transposon-based approach to identify molecular pathways involved in the pathogenesis of Multiple Myeloma in the presence and absence of Myc overexpression.

Finally, in collaboration with other scientists and doctors at the Sanger Institute, the European Bioinformatics Institute and the University of Cambridge, we are developing molecular and computational tools to help us understand the clonal evolution of leukaemias arising through insertional mutagenesis and to accelerate the process of incorporating scientific findings into clinical diagnosis and decision-making.
