E-mail: emilyc@scripps.edu <h3>SPECIFIC AIMS</h3> The aims of this study were: 1) to apply a sophisticated shot-gun proteomic method (MudPIT) to carry out the proteome analysis of breast cancer cells with or without the metastatic tumor suppressor gene maspin; and 2) to generate a mechanistic hypothesis of maspin’s role in tumor metastasis based on the observed proteome modification. <h3>PRINCIPAL FINDINGS</h3> <h3>1. A large scale proteome analysis of metastatic breast cancer cells and of the changes that took place by restoring maspin expression was conducted</h3> <h3>2. Three metastasis-related protein networks
