Insulin-Like Growth Factor Receptors May Be Involved in Development of Resistance to the Breast Cancer Drug Herceptin
December 13, 2001 (EMBARGOED FOR RELEASE 4 P.M. EST December 18)
New research suggests that insulin-like growth factor-I (IGF-I) receptors may be involved in the development of resistance to the breast cancer drug Herceptin.
Herceptin (Genentech, San Francisco) is a monoclonal antibody that has important therapeutic activity against breast cancers that overexpress the protein HER2. However, most breast cancers develop a resistance to Herceptin in less than a year through mechanisms that are
