Marrakech – British scientists has discovered the reason behind the retention of some smokers’s lungs healthy despite they smoke their entire life.
An analysis that included more than 50 thousand people showed favorable mutations occur to the DNA of smokers and lead to enhancing the lungs function and, at the same time, hiding the deadly effects of smoking.
Scientists of the British Council of Medical Researches said that the outcome of this analysis may lead to discovering new medicines in order to improve the lungs function.
Researchers analyzed an enormous amount of genetic and health data of volunteers in Britain. In the results, Scientists found many diseases, including the Chronic Obstructive Pulmonary Disease (COPD). This illness leads to coughing, breath shortness, and chest infections. It is estimated that 3 million people are affected by COPD in the UK.
Scientists discovered that some parts of smokers’ DNA reduce the risk of being infected by COPD, when comparing smokers, non-smokers, people with the disease, and people not affected by COPD. Consequently, smokers who have “good genes” are less likely to develop Chronic Obstructive Pulmonary Disease than those who don’t.
Other effects of smoking, which were not covered by the study, include heart disease and cancer. The researchers also revealed parts of the genetic code that appear only in smokers. This genetic code explains how people become addicted to nicotine.
In an interview with BBC, Ian Jarrold, the Head of Research at the British Foundation of Lung Diseases, said “These findings represent a significant step forward in helping us achieve a clearer picture about the fascinating and intricate reality of lung health.”
Jarrold went on to add, “Understanding genetic predisposition is essential in not only helping us develop new treatments for people with lung disease but also in teaching otherwise healthy people how to better take care of their lungs.”
