Tobacco smoking increases the risk of at least 17 classes human cancer. We analyzed somatic mutations and DNA methylation in 5243 cancers types for which tobacco confers an elevated risk. Smoking is associated with increased mutation burdens multiple distinct mutational signatures, contribute to different extents cancers. One these mainly found derived from tissues directly exposed smoke, attributable misreplication damage caused by carcinogens. Others likely reflect indirect activation...
Highlights•41 of 79 environmental agents yielded substitution signatures•6 produced double-substitution signatures and 8 indel signatures•Several match or exhibit similarity with found in human tumors•Topographical mutational asymmetries reveal mechanistic insightsSummaryWhole-genome-sequencing (WGS) tumors has revealed distinct mutation patterns that hint at the causative origins cancer. We examined 324 WGS human-induced pluripotent stem cells exposed to known suspected carcinogens....
Lung cancer is a leading cause of mortality with an inter-individual difference in susceptibility to the disease. The inheritance low-efficiency genotypes involved DNA repair and replication may contribute susceptibility. We investigated 44 single nucleotide polymorphisms (SNPs) 20 genes including excision (NER) XPA , ERCC1 ERCC2/XPD ERCC4/XPF ERCC5/XPG; base (BER) APE1 / APEX OGG1 MPG XRCC1 PCNA POLB POLι LIG3 EXO1; double-strand break (DSB-R) XRCC2 XRCC3 XRCC9 NBS1 ATR; direct damage...
EXPOsOMICS is a European Union funded project that aims to develop novel approach the assessment of exposure high priority environmental pollutants, by characterizing external and internal components exposome. It focuses on air water contaminants during critical periods life. To this end, centres 1) at personal population levels within existing short long-term studies, exploiting available tools methods which have been developed for monitoring (PEM); 2) multiple "omic" technologies analysis...
Whole genome sequencing of human tumours has revealed distinct patterns mutation that hint at the causative origins cancer. Experimental investigations mutations and spectra induced by environmental mutagens have traditionally focused on single genes. With advent faster cheaper platforms, it is now possible to assess in experimental models across whole genome. As a proof principle, we examined profiles mouse embryo fibroblasts immortalised following exposure benzo[a]pyrene (BaP), ultraviolet...
Hemochromatosis and Wilson disease (WD), characterized by the excess hepatic deposition of iron copper, respectively, produce oxidative stress increase risk liver cancer. Because frequency p53 mutated alleles in nontumorous human tissue may be a biomarker oxyradical damage identify individuals at increased cancer risk, we have determined from WD hemochromatosis patients. When compared with samples normal controls, higher frequencies G:C to T:A transversions codon 249 (P < 0.001) C:G A:T...
Background Larvae of the greenbottle fly Lucilia sericata are used routinely for clinical treatment difficult necrotic and infected wounds. Degradation by proteinases contained in larval excretory/secretory (ES) products is thought to contribute wound debridement removal dead tissue. However, proteinase activity may also affect host tissue remodelling processes. Objectives To identify proteolytic enzymes derived from L. ES with activities against fibrin extracellular matrix (ECM) components....

The aim of this project was to devise and test improved protocols the 32P-postlabelling assay for detection carcinogen-DNA adducts. intention reverse drift different investigators using increasingly divergent experimental conditions. This would lead a more standardized that can be used in future applications by monitoring human exposure genotoxic agents, permitting meaningful comparisons between studies or participants same study. As part process, there perceived need carcinogen-modified DNA...
