This project has 4 main lines of investigation. Firstly, we are currently undertaking a comprehensive molecular analysis of lung cancer tissues from European Americans and African American. These samples are being analysed fo microRNA, coding gene expression, genetics and methylation. The goal of these analyses are to understand whether differences in tumor biology exist in lung cancers from African Americans and European Americans. Understanding such differences could provide clues for etiology, prevention and new treatments. In addition, a major goal of this project is to understand the biology behind genetic loci specifically associated with lung cancer incidence in African Americans. This work extends from an NCI-led GWAS of lung cancer in African Americans. Thirdly, based on previous literature suggesting that the cytokine profile is different in African Americans and European Americans, and ongoing work in European Americans showing that cytokine profiles are very promising risk, diagnostic and prognostic biomarkers, we are investigating whether a specific inflammatory cytokine profile is also associated with the diagnosis and prognosis of lung cancer in European Americans. Finally, as the main causes of the disparities in incidence are unknown, we are also conducting population studies to assess the potential causes

该项目有4条调查主线。首先，我们目前正在对欧洲裔美国人和非裔美国人的肺癌组织进行全面的分子分析。这些样本正在分析microRNA、编码基因表达、遗传学和甲基化。这些分析的目标是了解非裔美国人和欧洲裔美国人的肺癌是否存在肿瘤生物学上的差异。了解这些差异可以为病因、预防和新的治疗方法提供线索。此外，该项目的一个主要目标是了解与非裔美国人肺癌发病率特别相关的基因位点背后的生物学。这项工作是从美国国家癌症研究所领导的非裔美国人肺癌的全球癌症研究延伸而来的。第三，根据以前的文献表明，非洲裔美国人和欧洲裔美国人的细胞因子谱不同，而欧洲裔美国人正在进行的工作表明，细胞因子谱是非常有希望的风险、诊断和预后生物标志物，我们正在调查特定的炎性细胞因子谱是否也与欧洲裔美国人肺癌的诊断和预后有关。最后，由于发病率差异的主要原因尚不清楚，我们也正在进行人口研究，以评估潜在的原因
