Christopher John Marshall FRS FMedSci (19 January 1949 – 8 August 2015^[1]) was a British scientist who worked as director of the Division for Cancer Biology at the Institute of Cancer Research.^[2] Marshall was distinguished for research in the field of tumour cell signalling. His track record includes the discovery of the N-Ras oncogene^[3] , the identification of farnesylation of Ras proteins,^[4] and the discovery that Ras signals through the MAPK/ERK pathway.^[5] These findings have led to therapeutic development of inhibitors of Ras farnesylation, MEK and B-Raf.

Early life

Marshall was born in Birmingham, UK, and educated at the King Henry VIII School, Coventry. He then studied Natural Sciences at the University of Cambridge followed by a DPhil in cell biology at the University of Oxford. His graduate studies were followed by post-doctoral work at the Imperial Cancer Research Fund laboratories at Lincoln’s Inn Fields (now part of the Francis Crick Institute) in London and the Dana-Farber Cancer Institute in Boston.^[6]

Oncogene research

In 1980, Marshall moved to The Institute of Cancer Research in London, and began studies to identify human cancer genes. This work, in collaboration with his colleague Alan Hall, resulted in the identification of NRAS, a new human oncogene.^[7] Subsequent work from his laboratory showed that NRAS has important roles in leukaemia and others demonstrated the role of NRAS in melanoma. Following the identification of NRAS, Marshall concentrated on studying how NRAS and the two other RAS genes, HRAS and KRAS, act in cancer. His work in the field of cell signalling showed how RAS and other signalling proteins are involved in transmitting signals from outside of the cell all the way to the cell nucleus.^[8] His work laid the foundation for studies that showed the importance of the BRAF cancer gene in melanoma.^[9]

At the time of his death,^[1] Marshall's laboratory studied the cell signalling mechanisms that allow cancer cells to disseminate through the body. In particular, these studies were focused on signal transduction pathways regulated by Ras and Rho family of small GTPases.^[10]
