Chromosomal aberrations in tire plant workers and interaction with polymorphisms of biotranformation and DNA repair genes
2008
Abstrakt
We evaluated chromosomal aberrations in lymphocytes of 177 workers exposed to xenobiotics in a tire plant and in 172 controls, in relation to their genetic background. Nine polymorphisms in genes encoding transformation enzymes and nine polymorphisms in genes involved in main DNA repair pathways were investigated for possible modulation of chromosomal damage..
Present results show that exposed individuals in the tire production, who smoke, exhibit higher chromosomal aberrations frequencies, and the extent of chromosomal damagemay additionally be modified by relevant polymorphisms
