DESCRIPTION (provided by applicant): The University of Texas M. D. Anderson SPORE in Pancreatic Cancer is focused on translating recent observations in molecular biology, cellular signaling, and DNA repair to patient care. This application outlines a strong institutional effort to foster research on the etiology, biology, and treatment of human pancreatic cancer that will translate basic research findings into concrete clinical research protocols involving pancreatic cancer patients. To accomplish this goal, five projects are proposed: Project 1 - A Novel Therapeutic Gene, p202, and its Potential in Pancreatic Cancer Therapy seeks to credential a specific new protein target that is applicable to pancreatic cancer because of its ability to inhibit the activity of NF-KappaB. The successful development of this strategy will lead to direct therapeutic application using a gene transfer approach. Project 2 - Role of COX-2 in Pancreatic Cancer Progression and Therapy will explore the mechanism of Cox-2 overexpression in pancreatic cancer. This project will specifically examine the hypothesis that EGF-EGF receptor interactions control PLA2 and COX2 expression in pancreatic cancer cells and that COX-2 regulates an important cell survival pathway. To address this issue in patients, a clinical trial entitled "Assessment of Biological Markers of Response to Treatment with Celecoxib and OSl 774 in Patients with Advanced Pancreatic Cancer" is proposed. Project 3 - NFkB Signaling Pathways in Pancreatic Cancer Biology & Therapy explores the biochemical effects and biologic consequences of a series of strategies to inhibit the EGFR - Akt - NFKappaB signaling pathway. Each approach tested has potential clinical relevance to pancreatic cancer. To clinically assess the impact of EGFR inhibition, a clinical trial entitled "Phase II Randomized Trial of Anti-Epidermal Growth Factor Receptor (EGFR) Antibody Cetuximab vs. Cetuximab Plus Gemcitabine in Patients with Advanced Pancreatic Cancer" is proposed. Project 4 - Regulation of Pancreatic Cancer Angiogenesis and Metastasis by Transcription Factor Sp1 will examine the hypothesis that disregulated expression and activation of Sp1 is responsible for aberrant expression of multiple angiogenic molecules that generates the angiogenic phenotype and sustains tumor growth and metastasis. Project 5 - DNA Repair as a Risk Factor for Pancreatic Cancer tests the hypothesis that DNA repair capacity is a risk factor for pancreatic cancer, and that polymorphisms in DNA repair and cell cycle genes modulate the efficiency of DNA repair capacity thereby increasing individual risk of pancreatic cancer or response to therapy. Data from two clinical trials in patients with resectable pancreatic cancer will examine the effect of DNA repair on patient survival following multi-modality therapy. To support these efforts, two Cores are proposed: Core - Biostatistics and Information Management will provide biostatistical support for the design and analysis of all Projects and clinical trials conducted through the SPORE. Core - Tissue Procurement and Distribution will facilitate the acquisition and distribution of pancreatic cancer and normal tissue to all SPORE Projects and collaborators. This Core will also evaluate and distribute all tumor biopsies and blood obtained from the clinical trials. We believe that our well-developed program will provide a significant and sustained impact on pancreatic cancer translational research and identify new research opportunities that will have an impact in reducing pancreatic cancer incidence and mortality.

描述（由申请人提供）：德克萨斯大学M。D.安德森孢子在胰腺癌的重点是翻译在分子生物学，细胞信号和DNA修复病人护理的最新观察。该申请概述了一项强有力的机构努力，以促进对人类胰腺癌的病因学、生物学和治疗的研究，将基础研究成果转化为涉及胰腺癌患者的具体临床研究方案。为了实现这一目标，提出了五个项目：项目1 -一种新的治疗基因，p202，及其在胰腺癌治疗中的潜力，旨在证明一种适用于胰腺癌的特异性新蛋白质靶点，因为它能够抑制NF-κ B的活性。这种策略的成功开发将导致使用基因转移方法的直接治疗应用。项目2 -考克斯-2在胰腺癌进展和治疗中的作用将探讨胰腺癌中考克斯-2过表达的机制。本项目将专门研究EGF-EGF受体相互作用控制胰腺癌细胞中PLA 2和COX 2表达以及考克斯-2调节重要细胞存活途径的假设。为了解决患者中的这个问题，提出了一项名为“在晚期胰腺癌患者中评估对塞来昔布和0 S1774治疗的反应的生物标志物”的临床试验。项目3 - NFkB信号通路在胰腺癌生物学和治疗探讨了一系列抑制EGFR - Akt - NFKappaB信号通路的策略的生化作用和生物学后果。测试的每种方法都与胰腺癌有潜在的临床相关性。为了临床评估EGFR抑制的影响，提出了一项名为“抗表皮生长因子受体（EGFR）抗体西妥昔单抗与西妥昔单抗联合吉西他滨治疗晚期胰腺癌患者的II期随机试验”的临床试验。项目4 -转录因子Sp1对胰腺癌血管生成和转移的调节将研究Sp1的表达和激活失调是多种血管生成分子异常表达的原因，这些血管生成分子产生血管生成表型并维持肿瘤生长和转移。项目5 - DNA修复作为胰腺癌的风险因素测试DNA修复能力是胰腺癌的风险因素的假设，以及DNA修复和细胞周期基因的多态性调节DNA修复能力的效率，从而增加胰腺癌的个体风险或对治疗的反应。来自两项可切除胰腺癌患者临床试验的数据将检查DNA修复对多模态治疗后患者生存率的影响。为了支持这些工作，提出了两个核心：核心-生物统计学和信息管理将为通过SPORE进行的所有项目和临床试验的设计和分析提供生物统计学支持。核心-组织采购和分发将促进胰腺癌和正常组织的采购和分发给所有SPORE项目和合作者。该中心还将评估和分发从临床试验中获得的所有肿瘤活检和血液。我们相信，我们完善的项目将对胰腺癌转化研究产生重大而持续的影响，并确定新的研究机会，这将对降低胰腺癌发病率和死亡率产生影响。
