For example, Ruoslahti and coauthors have been developed a theranostic nanosystem, which consists of iron oxide nanoworms conjugated with a composite peptide with proapoptotic domain (i.e., therapy motif) and cell surface p32 protein binding domain (i.e., tumor-homing motif).52,53 The in vivo experimental results indicate that the as-prepared theranostic nanosystem has excellent homing and penetrating activity in mouse-bearing breast tumor models, and enables to effectively retard tumor growth. Here, C1QBP is linked to neoplasm.
