项目摘要

DESCRIPTION (provided by applicant): Colorectal cancer has many diet and lifestyle factors that contribute to the etiology. Data suggest that differences in etiology exist by tumor site, age, and sex, and that certain exposures modify the effects of others, indicating the importance of various diet and lifestyle factors in certain environments. Major factors that modify the effects of other risk factors are'use of aspirin and ibuprofen-type drugs. Our previous data have shown that NSAIDs interact with a variety of diet and lifestyle factors, including dietary fat, BMI, insulin- related genes, and estrogen. We hypothesize that genetic variation in an inflammation-related signaling pathway and in a pathway where inflammation, insulin and estrogen converge (designated as a metabolic signaling pathway) will most likely have implications for disease risk. We propose to study two pathways which have not previously been studied with colorectal cancer. We utilize data previously collected on 2780 incident cases of colorectal cancer and 3025 population-based controls to obtain a better understanding of the inter-relationship between inflammation, insulin, and estrogen. We examine known functional polymorphisms and evaluate haplotypes in candidate genes in an inflammation-related pathway (IL6, IL8, IL10, NFKB, TNF-A, IL4, IL1, ILIRA and IFNG) and genes located at key junctions where other cellular signaling pathways converge which we describe as a metabolic signaling pathway (SOC1, SOC2, AKT, FRAP1 (mTOR), TSC1, TSC2, P13K, LKB, AMP, PTEN, S6K.VEGF, STAT1, STAT6, JNK1, and pSSMAPK). We will test associations between genetic polymorphisms and haplotypes of these genes with colorectal cancer. We will evaluate the interaction of these genes with NSAIDs/aspirin, estrogen, BMI, dietary fat, antioxidants, and physical activity. We will evaluate associations of these polymorphisms/haplotypes with specific types of tumor mutations. We will utilize statistical methods to gain insight into how these genes relate to specific disease pathways and how genes inter-relate along these pathways. We include test of functionality for all genes and SNPs identified as being assocatied with CRC and we will validate study findings using statistical techniques that allow for test and validation. Identification of polymorphisms or haplotypes that are relevant to colorectal cancer will advance our understanding of etiology, may lead to specific health recommendations, and can identify targets for drug therapy.

描述（由申请人提供）：大肠癌具有许多有助于病因的饮食和生活方式因素。数据表明，肿瘤部位，年龄和性别存在病因的差异，并且某些暴露会改变他人的影响，表明某些环境中各种饮食和生活方式因素的重要性。改变其他危险因素的影响的主要因素是阿司匹林和布洛芬型药物的使用。我们以前的数据表明，NSAIDS与各种饮食和生活方式因素相互作用，包括饮食脂肪，BMI，胰岛素相关基因和雌激素。我们假设在炎症相关的信号通路以及炎症，胰岛素和雌激素融合（指定为代谢信号通路）的途径中，遗传变异很可能会对疾病风险产生影响。我们建议研究两种以前未接受结直肠癌研究的途径。我们利用先前收集的有关2780例大肠癌事件和3025个基于人群的对照的数据，以更好地了解炎症，胰岛素和雌激素之间的相互关系。我们检查已知的功能性多态性并评估与炎症相关途径（IL6，IL8，IL10，NFKB，TNF-A，IL4，IL4，IL1，IL1，ILIRA和IFNG）中的候选基因中的单倍型，并评估众所周知的信号途径，我们描述了一个社会的信号，我们将群体融合了（我们描述了一个社会），该途径是群众群体，我们的信号是群众的。 FRAP1（MTOR），TSC1，TSC2，P13K，LKB，AMP，PTEN，S6K.VEGF，STAT1，STAT6，JNK1和PSSMAPK）。我们将测试这些基因与结直肠癌的遗传多态性和单倍型之间的关联。我们将评估这些基因与NSAID/阿司匹林，雌激素，BMI，饮食脂肪，抗氧化剂和体育活动的相互作用。我们将评估这些多态性/单倍型与特定类型的肿瘤突变的关联。我们将利用统计方法来深入了解这些基因如何与特定疾病途径以及基因如何沿这些途径相互关系。我们包括对所有基因和SNP的功能测试测试，该基因和SNP与CRC相关，我们将使用允许测试和验证的统计技术验证研究结果。与结直肠癌相关的多态性或单倍型的鉴定将提高我们对病因的理解，可能会导致特定的健康建议，并可以识别药物治疗的靶标。
