Washington D.C. [USA], Sept.22 : A new research says that smoking leaves its impression on the human genome in the form of DNA methylation, a process by which cells control gene activity.

The new findings suggest that DNA methylation could be an important sign that reveals an individual's smoking history and could provide researchers with potential targets for new therapies.

"These results are important because methylation, as one of the mechanisms of the regulation of gene expression, affects what genes are turned on, which has implications for the development of smoking-related diseases," said author Stephanie J. London, adding, "Equally important is our finding that even after someone stops smoking, we still see the effects of smoking on their DNA."

Washington D.C. [USA], Sept.22 : A new research suggests that smoking may shorten the lives of those with terminal illness, such as ALS (amyotrophic lateral sclerosis).

ALS damages nerve cells in the brain and spinal cord. These cells control many vital muscle functions, including speaking, swallowing and breathing.

Though no cure for this disease has been found, scientists have identified several risk factors, including genes, gender, age and underlying health issues.

For this study, researchers explored the link between tobacco and development of ALS.

They collected data on the smoking habits of 650 people diagnosed with ALS between 2007 and 2011 in northern Italy. They also looked at chronic lung disease (COPD) among these patients.
