Infection of human dendritic cells (DCs) by negative-strand RNA viruses, such as Newcastle disease virus, leads to the induction of the IFNbeta gene, IFNB1, through the activation of the RNA helicase RIG-I, which is encoded by DDX58. Expression levels of IFNB1 and DDX58 in infected DCs showed positive correlations at the population and the single-cell(More)
Glutathione S-transferases (GSTs) are known to take part in detoxification of many potentially carcinogenic compounds. Therefore, polymorphisms of the GST genes have been considered as potentially important modifiers of individual risk of environmentally induced cancers. The association between lack of glutathione S-transferase M1 gene (GSTM1 null genotype)(More)
Glutathione S-transferases GSTM1, GSTM3, GSTP1 and GSTT1 are involved in the detoxification of active metabolites of several carcinogens in tobacco smoke. We studied the potential role of GSTM3 and GSTP1 gene polymorphisms either separately, or in combination with GSTM1 and GSTT1 gene polymorphisms, in susceptibility to lung cancer using peripheral blood(More)
We investigated the roles of EPHX1 Tyr113His and His139Arg polymorphisms in lung cancer susceptibility in a Finnish study population comprising of 230 lung cancer cases and a large control group (n=2105). The controls were distributed into five age strata, which enabled us to examine the potential age-related changes in the putative EPHX1 at-risk genotypes(More)
Several polymorphic glutathione S-transferase enzymes are involved in the detoxification of active metabolites of many potential carcinogens from tobacco smoke and may therefore be important in modulating susceptibility to smoking-related cancers. As part of a hospital-based case-control study performed in France among Caucasian smokers, we studied GSTM1,(More)
Glutathione S-transferases (GSTs) are involved in detoxification of reactive metabolites of carcinogens and, therefore, could be potentially important in susceptibility to cancer. The associations between larynx cancer risk and GSTM3 and GSTP1 gene polymorphisms, either separately or in combination with GSTM1 and GSTT1 gene polymorphisms, were evaluated(More)
Myeloperoxidase (MPO) is released from neutrophils in lung tissue in response to exposure to various pulmonary insults, including tobacco smoking. This enzyme is involved in the activation of an intermediate metabolite of benzo(a)pyrene to the highly reactive benzo(a)pyrene diol epoxide. A (-463)G --> A polymorphism in the promoter region of the MPO gene(More)
The present study comprised a biomonitoring study in 95 workers occupationally exposed to styrene and 98 unexposed controls, employing an integrated approach involving biomarkers of exposure, effect, and susceptibility. Airborne styrene was evaluated at workplace, and urinary styrene metabolites, mandelic acid (MA), phenylglyoxylic acid (PGA), vinylphenols(More)
Myeloperoxidase (MPO) is released from neutrophils in lung tissue in response to exposure to various pulmonary insults, including tobacco smoking. This enzyme is involved in the activation of an intermediate metabolite of benzo(a)pyrene to the highly reactive benzo(a)pyrene diol epoxide. A G 3 A polymorphism in the promoter region of the MPO gene has been(More)
BACKGROUND Xenobiotic metabolizing enzymes (XMEs) are important detoxifiers of hazardous environmental agents, and their polymorphisms may therefore modify the risk of environmentally induced cancers. Consequently, the XME polymorphisms have been extensively studied in this context during recent years. Particular attention has been given to the(More)
