Binge and Heavy drinkers

Deoxyribonucleic acid is a molecule composed of two chains that coil around each other to form a double helix carrying the genetic instructions used in the growth, development, functioning; and reproduction of all known living organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids; alongside proteins; lipids and complex carbohydrates (polysaccharides); nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.
Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a Rutgers-led study in the journal Alcoholism: Clinical & Experimental Research. The Rutgers-led team’s findings may eventually help researchers identify biomarkers measurable indicators such as proteins or modified genes that could predict an individual’s risk for binge or heavy drinking.
“The researcher finds that people who drink heavily may change their DNA in a way that makes them crave alcohol even more. “This may help explain why alcoholism is such a powerful addiction; and may one day contribute to new ways to treat alcoholism or help prevent at-risk people from becoming addicted.”

Harmful Use of Alcohol

In 2016, more than 3 million people died from the harmful use of alcohol, according to a World Health Organization report. That is 5 percent of all global deaths. More than three-quarters of alcohol-caused deaths were among men. The harmful use of alcohol also caused 5.1 % of the worldwide toll of disease and injuries. Scientists at Rutgers and Yale University School of Medicine focusing on two genes implicating in the control of drinking behavior: PER2, which influences the body’s biological clock; and POMC, which regulates our stress-response system.

Binge and Heavy Drinkers

By comparing groups of moderate, binge and heavy drinkers; the researchers find that the two genes had changed in the binge and heavy drinkers through an alcohol-influenced gene modification process called methylation. The binge and heavy drinkers also showed reductions in gene expression or the rate at which these genes create proteins. These changes increased with greater alcohol intake.

Additionally, in an experiment, the drinkers viewed stress-related, neutral or alcohol-related images. They also shown containers of beer and subsequently tasted beer; their motivation to drink evaluated. The result: alcohol-fueled changes in the genes of binge and heavy drinkers were associated with a greater desire for alcohol.

The findings may eventually help researchers identify biomarkers; measurable indicators such as proteins or modified genes that could predict an individual’s risk for binge or heavy drinking; who works in the School of Environmental and Biological Sciences.
