项目摘要

The overall theme of Berkeley's Biological Response Indicators of Environmental Stress Center is "Biomarkers and Biosensors for Studies of Blood Cancer Risks." This theme reflects the long-standing interests of our investigators in the etiology of human leukemias and lymphomas and our close associations with clinicians and epidemiologists who maintain repositories of stored tissues for molecular epidemiology studies of these diseases. It also highlights particular research strengths of our investigators in the areas of microsensing, chemistry, toxicology, bioinformatics, and exposure biology. Our Program has the following three projects and goals: Project 1 - Protein Adducts as Molecular Signatures of Carcinogen Dose. The major goal of Project 1 is to demonstrate the viability of 'protein adductomics' as a true 'omics' approach, one of general importance to the GEI and of particular importance to Exposure Biology. We propose to enrich unknown cysteinyl adducts of human serum albumin and then to profile these adducts in the serum of lymphoma cases and controls. If successful, this project will identify unknown initiators of human lymphomas. Project 2 - High Throughput Detection of Genetic Mutations as Biomarkers of Hematological Cancer Risk. This project will develop and apply lab-on-a-chip technologies to investigate mutation spectra in individual cells that are involved with the mechanism of human leukemia. By amplifying DMA from single cells, we will measure mutation spectra at critical loci in susceptible individual cells surrounded by normal cells. Then, by developing high-throughput single-cell PCR assays to detect low frequencies of mutations of importance in leukemia, we will prepare a biased library of hot-spots for mutations in key genes or regions related to leukemia. Project 3 - Advanced Biosensing for Molecular and Cellular Biomarkers. This project will develop biosensors that make it possible to perform immunoassays quickly and conveniently, either in a laboratory or in the field, using a single drop of blood. It will validate the biosensors by measuring blood protein adducts of polycyclic aromatic hydrocarbons in the blood from asphalt and construction workers. By achieving these goals our Center will open up important new avenues of inquiry regarding the links between chemical exposures and human cancers. It will also develop the technology to utilize protein adducts as biomarkers of internal dose in large epidemiology studies.

伯克利环境压力生物反应指标中心的总体主题是“血癌风险研究的生物标志物和生物传感器”。这一主题反映了我们的研究人员对人类白血病和淋巴瘤病因学的长期兴趣，以及我们与维护这些疾病分子流行病学研究的储存组织库的临床医生和流行病学家的密切联系。它还突出了我们的研究人员在微传感、化学、毒理学、生物信息学和暴露生物学等领域的特殊研究优势。项目一：蛋白质加合物作为致癌物剂量的分子特征。项目1的主要目标是证明“蛋白质内收组学”作为一种真正的“组学”方法的可行性，这对GEI具有普遍重要性，对暴露生物学尤其重要。我们建议富集人血清白蛋白的未知半胱氨酸加合物，然后在淋巴瘤病例和对照组的血清中分析这些加合物。如果成功，该项目将确定未知的人类发起者
