项目摘要
DESCRIPTION (provided by applicant): Colorectal cancer (CRC) is the most common gastrointestinal malignancy in the United States and it is commonly diagnosed in both men and women. It was estimated that 146,940 new cases were diagnosed, and 56,730 deaths from CRC occurred in 2010. The optimal management of patients with colorectal adenomatous polyps depends on the accuracy of appropriate staging strategies because patients with similar colorectal adenocarcinoma architecture display heterogeneity in the course and outcome of the disease. While a number of treatment modalities have been developed for CRC, we still are far from finding why there are a great deal of heterogeneity show by CRC patients during the course and outcome regarding the disease racial differences. Therefore, more research is needed not only to understand the basic processes that are subverted by early stages of CRC cells to gain a proliferative advantage, also why there are a great deal of racial differences show
by CRC patients during the course and outcome of the disease. The accumulation of ROS and oxidative DNA damage during the course of a lifetime may be deleterious and lead to specific mitochondrial genome alterations that may be associated in the progression of CRC. Our central hypothesis is that mtDNA gene profiling in primary tissues of colorectal adenomatous polyps will identify clinically relevant patterns of mutations and expression in histological colorectal tumor stages and subgroups of Caucasian and African-American with aggressive tumors. Specific aims are: (i) to determine and evaluate the role of mtDNA polymorphism/mutations play between African American and Caucasian patients susceptibility to the progression of CRC. (ii); to determine whether there are differences in the level of mitochondrial protein expression profiles between "early" stages of colorectal tumors and normal surrounding colorectal tissue from individual patients of African-American and Caucasian origin. This study is different from other previous studies in that a multiplatform of technologies will be performed to accurately evaluate genetic changes in epithelial colorectal adenopolyps and sub-classification of patients with similar disease, correlating the results with racial/ethnical populations. Results from this study should provide basic knowledge to the development of proper clinical tests for prediction of CRC progression in patients' clinical outcome, which is required for efficacious therapies.
描述(由申请人提供):结直肠癌(CRC)是美国最常见的胃肠道恶性肿瘤,在男性和女性中都很常见。据估计,2010年诊断出146,940例新病例,56,730例结直肠癌死亡。结直肠腺瘤性息肉患者的最佳治疗取决于适当分期策略的准确性,因为具有相似结直肠腺癌结构的患者在疾病的过程和结果上表现出异质性。虽然已经开发了许多治疗结直肠癌的方法,但我们仍然远远没有发现为什么结直肠癌患者在病程和结果中表现出大量的异质性,这与疾病的种族差异有关。因此,不仅需要更多的研究来了解早期CRC细胞被破坏以获得增殖优势的基本过程,还需要更多的研究来了解为什么存在大量的种族差异
