项目摘要
I have sought the potential of the tumor targeting to achieve successful gene the rapy for pancreatic cancer or hepatoma including antisense therapy.1. Studies concerning K-ras, DPC4, p53 and cyclin A in pancreatic cancer and the inhibitory effect of caffein on hepatocarcinogenesis have been performed, and the results have been published or are in press. It seems to be worthy to design a strategy of gene therapy for pancreatic cancer or hepatoma by targeting the ras signalling pathway.2. A novel tumor-targeting peptide vector (cRGD-hK) has been developed, that is intended to be systemically and repeatedly administered to patients with advanced solid tumors (the patent application has been done). The peptide vector of 36 1-amino acid residues, CRGDCF (K[H-]KKK) 6, has three elements : (i) a tumor-homing RGD motif to target tumor tissues, (ii) cationic oligolysine to form complexes with plasmid DNA or oligonucleotides, and (iii) histidyl residues to facilitate the escape from the acidic endosomes. Using CMV-driven luciferase expression plasmids as a reporter in pancreatic cancer and hepatoma celllines, the potential usefulness as a tumor-targeting vector was demonstrated in vitro and in vivo. The results were presented at the 3rd Conference of American Society of Gene Theraphy and at the 9th International Conference of Cancer Gene Therapy. Even if the targeting of cancer cells is successful, it seems to be unrealistic to expect a transduction of the majority of cells. In addition to repetitive antisense theraphy, we propose a potential non-viral gene theraphy for advanced pancreatic cancer or hepatoma through use of the tumor-targeting peptide vector and the concept of RNA interference.
本课题的研究目的是探索肿瘤靶向治疗胰腺癌或肝癌的可能性,包括反义治疗.关于胰腺癌中K-ras、DPC 4、p53和cyclin A的研究以及咖啡因对肝癌发生的抑制作用,已发表或正在出版。以ras信号通路为靶点设计胰腺癌或肝癌的基因治疗策略具有重要意义.已经开发了一种新型的肿瘤靶向肽载体(cRGD-hK),旨在全身重复给药于晚期实体瘤患者(专利申请已完成)。36个1-氨基酸残基的肽载体CRGDCF(K[H-]KKK)6具有三个元件:(i)靶向肿瘤组织的肿瘤归巢RGD基序,(ii)与质粒DNA或寡核苷酸形成复合物的阳离子寡聚赖氨酸,和(iii)促进从酸性内体逃逸的组氨酰残基。使用CMV驱动的荧光素酶表达质粒作为胰腺癌和肝癌细胞系中的报告基因,在体外和体内证明了作为肿瘤靶向载体的潜在有用性。研究结果在第三届美国基因治疗学会会议和第九届国际癌症基因治疗会议上发表。即使靶向癌细胞是成功的,期望转导大多数细胞似乎是不现实的。除了重复的反义治疗外,我们提出了一种潜在的非病毒基因治疗晚期胰腺癌或肝癌,通过使用肿瘤靶向肽载体和RNA干扰的概念。
