In a study recently published in the journal Human Molecular Genetics the researchers have examined how the genes are changed in smokers and users of non-smoke tobacco. They could identify a large number of genes that were altered in smokers but found no such effect of non-smoke tobacco.
"This means that the epigenetic modifications are likely not caused by substances in the tobacco, but by the hundreds of different elements that are formed when the tobacco is burnt," says Åsa Johansson, researcher at the Department of Immunology, Genetics and Pathology at Uppsala University and Uppsala Clinical Research Center, who has led the study
