The purpose of this study was to develop the delivery system of therapeutic molecules responding to the abnormal G protein-coupled receptor signaling for diagnosis and treatment of cardiovascular disease. Novel peptide substrates with high affinity for abnormal cellular signals were identified. Delivery system consisted of hydrophilic neutral polymer as the main chain and peptide substrates as side chains. When the system/gene complex was transfected into cells, gene expression increased in abnormal cells overexpressing target signals, but very low expression was found in normal cell.

本研究的目的是开发G蛋白偶联受体信号异常的治疗分子递送系统，用于心血管疾病的诊断和治疗。鉴定了对异常细胞信号具有高亲和力的新型多肽底物。给药系统以亲水性中性聚合物为主链，以多肽底物为侧链。当系统/基因复合体进入细胞后，过度表达靶信号的异常细胞的基因表达增加，而在正常细胞中表达很低。
