LC-NMR Study Biomarkers to Detect Lung Cancer
Lung CancerLung cancer is the most common cancer in men and the fourth most common cancer in women worldwide. Until today no effective method permits the early detection of lung cancer. Consequently, lung cancer is often diagnosed owing to symptoms of advanced disease. To address this problem, detection methods with an improved sensitivity and specificity are urgently needed. Over the past decade, accumulating evidence shows that the metabolism of cancer cells differs from that of normal cells. More specifically, the entire metabolism of cancer cells is reorganized or reprogrammed to increase anabolic reactions that induce cell growth and survival. Metabolic reprogramming during the development of cancer is driven by aberrant signaling pathways due to the activation of oncogenes and the loss of tumor suppressor genes. Furthermore, the microenvironment of the tumor plays a role in metabolic reprogramming. The altered cancer metabolism is characterized by an increased glycolysis, the production of lactate and the biosynthesis of macromolecules, such as proteins, lipids and nucleotides. Cancer cells have a high glycolytic rate and eliminate most of the glucose-derived carbon as lactate rather than oxidizing it completely via oxidative phosphorylation, a phenomenon known as the Warburg effect. The breakdown of glucose and other nutrients leads to a high energy production and provides the Krebs cycle with intermediates, which consequently are allocated to metabolic pathways that support biosynthesis. Metabolites are the end products of cellular metabolism and are therefore closely related to the observed phenotype. Disturbances in biochemical pathways which occur during the development of cancer consequently provoke changes in the metabolic phenotype. As a result, low-molecular weight metabolites are very attractive biomarkers for different cancer types. Nuclear magnetic resonance (NMR) spectroscopy enables the identification and quantitative analysis of complex mixtures of metabolites, as in plasma and serum, without an extended sample preparation. The present study aims to determine the metabolic phenotype of lung cancer by means of proton (1H)-NMR spectroscopy. Once the phenotype determined (training cohort), this has to be validated by an independent cohort.
Study of Lung Cancer in Appalachian Kentucky: The Role of Environmental Carcinogens
Lung CancerThis is a research study about the relationship between lung cancer and environmental risk factors. The purpose of this study is to try to understand the effects of trace elements such as arsenic and chromium, as well as radon on the development of lung cancer. To do this, the investigators will collect information and environmental and biologic specimens from people who live in Appalachian Kentucky who a) have lung cancer or b) don't have lung cancer and will serve as control subjects. The investigators will create a specimen repository of from these people and their residences to compare differences in many risks factors for cancer. By doing this study, the investigators hope to learn why there are more lung cancers in Kentucky's fifth Congressional District than anywhere else in the nation.
