DNA repair genes have an important role in protecting individuals from cancer-causing agents. Polymorphisms in several DNA repair genes have been identified and individuals with non-dramatic reductions in the capacity to repair DNA damage are observed in the population, but the impact of specific genetic variants on repair phenotype and cancer risk has not(More)
DNA adducts in peripheral leukocytes are considered a reliable indicator of internal dose exposure to genotoxic agents and, possibly, of cancer risk. We investigated their association with diet and other individual characteristics in healthy adults. The prospective study EPIC-Italy, a section of a larger European project, enrolled 47,749 men and women, aged(More)
Glioblastoma multiforme (GBM), a malignant astrocytic tumour, represents the most frequent tumour of the human brain. Nevertheless, its molecular pathology is not well understood. We utilized the immune system, which contributes to cancer protection, to help identify new GBM-related genes. By screening a human GBM cDNA library with autologous patient serum(More)
Roundup is a postemergence herbicide acting on the synthesis of amino acids and other important endogenous chemicals in plants. Roundup is commonly used in agriculture, forestry, and nurseries for the control or destruction of most herbaceous plants. The present study shows that Roundup is able to induce a dose-dependent formation of DNA adducts in the(More)
Peripheral blood DNA adducts have been considered an acceptable surrogate for target tissues and possibly predictive of cancer risk. A group of 114 workers exposed to traffic pollution and a random sample of 100 residents were drawn from the EPIC cohort in Florence, a population recently shown to present increased DNA adduct levels (Palli et al., Int J(More)
The 'Mediterranean diet', a diet rich in cereals, fruit and vegetables, has been associated with lowering the risk of a variety of cancers of the digestive tract and the bladder. In a previous study, we showed that the high phenolic content these dietary components produce in the urine could be associated with higher antimutagenic properties of the urine(More)
Industrial and urban workers may be exposed to significant levels of air pollutants resulting from the incomplete combustion of organic matter. The authors performed a meta-analysis of 13 DNA-adduct studies ((32)P-DNA postlabeling technique) on occupational cohorts exposed to air pollution. The association between levels of DNA adducts and air pollution(More)
The glioma amplified sequence 41 (GAS41) was previously isolated by microdissection mediated cDNA capture from the glioblastoma multiforme cell line TX3868 and shown to be frequently amplified in human gliomas. We determined the complete cDNA sequence of the GAS41 gene, demonstrated that the GAS41 protein is evolutionarily conserved, specifically at the(More)
Several large prospective investigations are under way or are planned in different parts of the world, aiming at the investigation of gene-environment interactions for chronic diseases. Technical, practical and ethical issues are raised by such large investigations. Here we describe how such issues were approached within a case-control study nested in EPIC,(More)
Using serological identification of recombinantly expressed tumor antigens (SEREX), we identified several autoantibodies against glioma-expressed antigens including GLEA1, GLEA2 and PHD-finger protein3 (PHF3). Analysing sera of 62 glioblastoma patients, we found an antibody response against GLEA1 in 15 sera (24.2%), against GLEA2 in 30 sera (48.4%) and(More)
