Scientists from the University of Michigan made a discovery in the field of smoking cessation. The researchers concluded that a genetic mechanism may be involved in nicotine addiction and withdrawal.
Experiments with unusual results were carried out on the roundworms Caenorhabditis elegans. First, they were accustomed to nicotine, and then they were deprived of this substance and studied the reaction.
As "Dni.ru" reports, as a result of experiments, scientists have isolated a number of genes and micro-RNAs responsible for increasing the production of proteins of nicotinic receptors. They play a key role in the development of smoking dependence. Therefore, the disposition of smokers to a bad habit can be explained by physiology.
The research results are planned to be used to study nicotine addiction in humans. Previously, the idea that genetics can explain the craving for smoking was rejected by the world scientific community.
Tobacco manufacturers have recently opposed the disclosure of the composition of cigarettes and the ban on the use of food additives in their production. Why tobacco workers do not want to talk about the composition and why additives are needed - in the material of the Moscow 24 portal.
