(Alles Europa News) – Vaping causes DNA changes and cancers along with smoking, established by American scientists.
Alles Europa News reports that a year ago, the same group of scientists conducted another study related to changes in gene expression of smokers.
A study of the cells of the epithelium of the oral cavity showed that those who smoke cigarettes and vapes have an abnormally high level of expression of certain genes associated with cancer.
“Our new study showed that epigenetic mechanisms, in particular changes in chemical labels, can contribute to abnormal gene expression in both vapers and smokers,” said scientist Ahmad Bessaratinia.
Alles Europa News reports that Studies by scientists at Keck Medical School at the University of Southern California (USA) on the genome of vapers and smokers found that both groups had epigenetic mutations that could lead to the development of cancer.
In this study, specialists examined changes in the epigenome in vapers.
To do this, they studied three groups of subjects:
those who smoked only electronic cigarettes, those who vaped and smoked ordinary cigarettes, and people without bad habits.
Alles Europa News reports that Blood samples were taken from all study participants to analyze the level of two types of epigenetic DNA tags:
methyl groups in the LINE-1 genetic sequences and hydroxymethyl radicals throughout the genome as a whole.
Alles Europa News reports that Of the 45 people who participated in the experiments, those who were fond of cigarettes (both electronic and conventional) had a significant decrease in the levels of both chemical labels compared to the control group.
“This does not mean that such people will develop cancer,” says one of the authors of the work, Ahmad Bessaratinia.
“But we see that changes in the chemical labels that are found in cancerous tumors are also found in people who drink or smoke – presumably due to exposure to cancer-causing chemical carcinogens present in cigarette smoke and – at lower levels -” in a pair of electronic cigarettes. “
