Christopher Marshall, English physician and biologist (b. 1948)
Christopher John Marshall FRS FMedSci (19 January 1949 – 8 August 2015) was a British scientist who worked as director of the Division for Cancer Biology at the Institute of Cancer Research. Marshall was distinguished for research in the field of tumour cell signalling. His track record includes the discovery of the N-Ras oncogene
, the identification of farnesylation of Ras proteins, and the discovery that Ras signals through the MAPK/ERK pathway. These findings have led to therapeutic development of inhibitors of Ras farnesylation, MEK and B-Raf.
