项目摘要

DESCRIPTION (provided by applicant): Our translational research group is dedicated to the development of innovative pancreatic cancer (PC) therapeutics. We have identified and characterized a novel PC related oncogene (the Cancer-associated Sm-like oncogene(CaSm)) and shown that: 1) it contributes to the transformed state in human and murine PC cells, and 2) adenovirus expressing CaSm antisense RNA (Ad-DhCaSm) significantly reduces in vitro and in vivo tumor growth with prolonged survivorship via cyclin B1/CDK1 dependent cytostatic cell cycle inhibition. These results indicate that the CaSm oncogene is critical to PC cell cycle control and could be targeted for therapeutic intervention. One of the major barriers to an effective CaSm-based gene therapy approach is achieving adequate in vivo tumor delivery. In fact, insufficient and/or non-effective delivery of gene vectors is a global problem limiting cancer gene therapy. We have recently established an exciting collaboration with Dr. Jesse Au's laboratory (Ohio State) that has developed a novel paclitaxel tumor priming approach capable of enhancing the delivery large molecules throughout an intraperitoneal tumor. Furthermore, we now have preliminary studies suggesting that the down-regulation of CaSm may induce a bystander effect in vivo- which could alleviate the need for delivery of the CaSm anti-sense gene to 100% of PC cells in vivo. Utilizing the downregulation of CaSm as a novel therapeutic intervention and our recently characterized murine CaSm PC model, our specific aims are to: 1) Determine whether paclitaxel tumor priming improves delivery and efficacy for pancreatic cancer gene therapy, 2) Define the impact of tumor priming on, and the mechanisms by which, the reduction of CaSm over-expression mediates a bystander effect, and 3) Define the mechanism by which CaSm upregulation leads to PC oncogenesis. The focus of this proposal is to combine a novel tumor priming approach with a promising gene target in order to develop innovative PC therapeutics. Successful completion of the proposed studies will advance the research in treatment of pancreatic cancer and, on a broader scope, validate an innovative technology for delivering gene vectors or other nanoparticles to intraperitoneal tumors
描述(由申请人提供):我们的转化研究小组致力于开发创新的胰腺癌(PC)治疗方法。我们已经鉴定并表征了一种新的PC相关癌基因(癌症相关Sm样癌基因(CaSm)),并表明:1)它有助于人和小鼠PC细胞的转化状态,2)表达CaSm反义RNA的腺病毒(Ad-DhCaSm)通过细胞周期蛋白B1/CDK 1依赖的细胞周期抑制剂显著降低体外和体内肿瘤生长并延长存活。这些结果表明,CaSm癌基因是至关重要的PC细胞周期控制,并可能成为治疗干预的目标。有效的基于CaSm的基因治疗方法的主要障碍之一是实现足够的体内肿瘤递送。事实上,基因载体的不充分和/或无效递送是限制癌症基因治疗的全球性问题。我们最近与Jesse Au博士的实验室(俄亥俄州)建立了令人兴奋的合作,该实验室开发了一种新型紫杉醇肿瘤引发方法,能够增强大分子在整个腹膜内肿瘤中的递送。此外,我们现在有初步的研究表明,下调的CaSm可能会诱导旁观者效应在体内-这可能会减轻需要交付的CaSm反义基因的PC细胞在体内的100%。利用下调CaSm作为一种新的治疗干预和我们最近表征的小鼠CaSm PC模型,我们的具体目标是:1)确定紫杉醇肿瘤引发是否改善胰腺癌基因治疗的递送和功效,2)定义肿瘤引发对CaSm过表达的减少介导旁观者效应的影响和机制,明确CaSm上调导致PC肿瘤发生的机制。该提案的重点是将一种新的肿瘤引发方法与有前途的基因靶点结合联合收割机,以开发创新的PC治疗方法。成功完成拟议的研究将推进胰腺癌治疗的研究,并在更广泛的范围内验证将基因载体或其他纳米颗粒递送到腹膜内肿瘤的创新技术
