How smoking affects DNA: it's better to know. Study

Cigarette manufacturers themselves are constantly talking about the dangers of smoking. This addiction leads to a decrease in lung volume, can cause the development of tuberculosis, chronic bronchitis and even malignant tumors. Despite this, the number of people willing to stop smoking is growing very slowly.To once again show society how harmful cigarette smoke is, scientists conducted a study. It was attended by staff from the National Institute of Environmental Health Sciences, led by Stephanie London.Experts have identified extremely negative effects on the body of a smoker. They found that it destroys the structure of DNA (the genome). It consists of 23 pairs of chromosomes, with about 25 thousand active genes. According to doctors, smoking destroys more than 7,000 of them.It is also important that under the influence of cigarette smoke, one part of the genes loses its activity, while the other increases it. This happens as a result of a change in their expression level. This phenomenon is called "DNA methylation". It is often these modifications that lead to diseases that are provoked by smoking.The scientists came to their opinion after conducting the experiment. For this purpose, the best scientific experiments were selected, in which approximately 16 thousand people took part.During the experiment, the results of 16 studies conducted at different times were analyzed. This was supposed to help identify how quickly DNA methylation occurs in smokers (the combination of cytosine and genes of the methyl group).The information received did not surprise the experts at all: they found that in the 5-year period after quitting the bad habit, some of the changes in DNA took place. But it should be noted that the remaining percentage of modifications remained even for three decades.Considering the above, whenever a person quits smoking, the risk of various diseases will remain quite high. That is why it is very important to avoid tobacco smoke and never be tempted by it.It should be recalled that another study was conducted earlier with the participation of almost 5,000 volunteers. On average, the participants were 75 years old. During the experiment, an echocardiogram was used to check the functioning of the heart and it turned out that those suffering from nicotine addiction had significantly thickened its walls. According to doctors, this is one of the causes of heart failure. Multi-bet lovers can benefit from accumulator bonuses.
