This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The investigators propose to obtain blood from approximately 500 patients scheduled for screening colonoscopy. The blood samples will be analyzed for pro-inflammatory cytokines. Polymorphisms in pro-inflammatory cytokines are associated with increased risk of gastric cancer. The hypothesis of this pilot, exploratory study is that there is a similar increased risk in the development of carcinoma of the colon. The investigators propose to obtain blood from approximately 500 patients scheduled for screening colonoscopy. The blood samples will be analyzed for pro-inflammatory cytokines: COX-2, IL-1b, IL-2, IL-6, IL-8, IL-10, PPARg, and TNFa. They plan to examine patients for history of red meat consumption, BMI, history of cancer, etc; colonoscopy; and allelic analysis. Subjects will be stratified into four populations: no polyps; low-grade polyps; high-grade polyps; colorectal cancer. Preliminary data show significance.

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 研究人员建议从大约500名计划进行结肠镜检查的患者身上采集血液。血液样本将被分析致炎细胞因子。 促炎细胞因子基因的多态与胃癌的风险增加有关。这项先导性、探索性研究的假设是，结肠癌的发生风险也有类似的增加。研究人员建议从大约500名计划进行结肠镜检查的患者身上采集血液。血液样本将分析促炎症细胞因子：COX-2、IL-1b、IL-2、IL-6、IL-8、IL-10、PPARg和TNFa。他们计划检查患者的红肉消费史、体重指数、癌症病史等；结肠镜检查；以及等位基因分析。受试者将被分成四组：无息肉；低度息肉；高度息肉；结直肠癌。初步数据显示了重要意义。
