Washington: It is already widely known that smoking is dangerous for smokers and their children, but a new research led by an Indian origin researcher has now revealed that nicotine exposure also causes asthma in the smoker’s grandchildren.Asthma is a major public health problem. It is the most common chronic disease of childhood. While there are many factors which contribute to asthma maternal smoking during pregnancy is a well known, and avoidable, risk.During pregnancy nicotine can affect a developing foetus’ lungs, predisposing the infant to childhood asthma. Researchers from Harbor-UCLA Medical Centre, California, tested the effect of nicotine exposure during pregnancy on rats, looking not only at their pups (F1) but also at second generation pups (F2).Exposure inside the uterus resulted in both male and female (F1) offspring having reduced lung function consistent with asthma. It also impaired lung function of their own offspring (F2), even though the F1 rats were not themselves exposed to nicotine once they were born. Levels of proteins increased by maternal smoking in the lungs of their offspring such as fibronectin, collagen and nicotinic aceylcholine receptors, were also found to be raised in the grandchildren.
