Dr. Courtneidge’s laboratory has studied the Src family of protein tyrosine kinases for a number of years. Src was the first oncogene to be discovered, and the first protein tyrosine kinase, and dissecting the mechanisms of Src transformation, regulation, substrate selection and function has proven to be a powerful research paradigm to understand tumorigenesis. In addition, since Src is frequently up-regulated and hyperactivated in human cancers, particularly of the breast and colon, such research is of direct relevance to human disease. Current research in the laboratory focuses on three main areas. The first involves defining how Src and its substrates, Tks4 and Tks5, drive the formation of podosomes and invadopodia, which are protrusive membrane structures of normal and cancer cells respectively that coordinate migration with extracellular matrix degradation. Since invadopodia are found in metastatic human cancer cells, the second focus is to identify and validate molecular targets in invadopodia, in order to define novel therapeutic points of intervention for the treatment of metastatic disease. The third research area involves defining in molecular detail the role of the Tks adaptor proteins during development, using both zebrafish and mice as model organisms.

Sara Courtneidge's Bio

Sara A. Courtneidge, Ph.D. is Professor and Director of the Tumor Microenvironment Program, and Director of Academic Affairs at Sanford-Burnham Medical Research Institute in La Jolla, California. Dr. Courtneidge was born in the UK, and received her undergraduate degree from the University of Leeds and her Ph.D. from the National Institute for Medical Research. Following postdoctoral study at the University of California, San Francisco, and an independent position at the National Institute for Medical Research, she joined the European Molecular Biology Laboratory in 1985, where she rose to the position of Senior Scientist. Changing course in 1994, Dr. Courtneidge joined SUGEN Inc. as Vice President of Research, where she guided novel kinase discovery and validation efforts in oncology. From 2001-2005 she was Distinguished Scientific Investigator at the Van Andel Research Institute in Grand Rapids, Michigan. Dr. Courtneidge joined Sanford-Burnham Medical Research Institute in May 2005.


Dr. Courtneidge received her undergraduate degree from the University of Leeds and her Ph.D. from the National Institute for Medical Research. She completed postdoctoral studies at the University of California, San Francisco.
