Professional background

Dr Marc Mansour is an honorary consultant haematologist at University College London Hospital and research group leader at the UCL Cancer Institute. He undertook his medical degree at the University of Edinburgh, medical training at King's College London and UCLH, followed by an MRC Clinical Research Training PhDship in the laboratory of Professors David Linch and Rosemary Gale at UCL, where he studied Notch signalling in acute leukaemia. He was funded by the Kay Kendell Leukemia Research Fund to undertake a travelling fellowship at Harvard Medical School and Dana-Farber Cancer Institute in Boston, USA. He was awarded the HMS Claudia Adams Barr Innovative Research award, and was a Harvard Medical School faculty member from 2012-2014. He is currently funded as a Bennett Senior Fellow by Bloodwise.

His research has focused on two aggressive haematological malignancies - T-cell acute lymphoblastic leukaemia (T-ALL) and acute myeloid leukaemia (AML). He has published extensively on the biology of acute leukaemia, authoring papers in Science, Nature, Nature Cell Biology, JCI, ELife, JCO and J Ex Med. His clinical interest is in ALL, AML and myelodysplasia (MDS).

Research interests

Dr Mansour has a long-standing interest in the biology of ALL and AML, particularly on the role of non-coding DNA in oncogene regulation. He has created several zebrafish models to study novel leukaemia oncogenes and tumour suppressors, with a particular focus on using these models to exploit the principal of synthetic lethality. This is based on the concept that, unlike normal cells, deficiency of tumour-suppressor genes in cancer cells creates a dependency on certain other genes for cell survival. Targeting these other genes with drugs should allow killing of tumour cells, while leaving normal cells unharmed.
